Understanding Unit Ventilators and Best Applications

Posted on by Brandon Sulikowski

If you went to public school in Long Island, Westchester or New Jersey, there’s a very good chance your school days were spent sitting in a classroom next to a Unit Ventilator.  Unit Ventilators have been around for decades as they are an easy solution to bring in required fresh air into classrooms with the units positioned underneath the windows.  

What are Unit Ventilators?

unit ventilators

Unit Ventilators, or “Unit Vents” or “UV”s for short, have been the solution of choice for these classroom applications as classrooms tend to need high amounts of outside air and their position along an exterior wall make them suitable to bring in large amounts of air but also offer the ability to operate in full economizer mode. The ability to operate in full economizer mode is really what makes this type of equipment stand out against other choices of interior mounted equipment like air handlers and fan coils.  

Over the years, in the northern climates unit ventilators were almost exclusively only delivering heating and fresh air. If there was a hot day in June, students would hope the teacher would set up a large oscillating fan for relief from the heat. Cooling coils were typically not found in UVs. That trend has recently changed as school districts are replacing these old, heating-only UVs with new versions with cooling coils to provide summertime cooling in classrooms. 

How VRF Systems Help

The growing popularity of Variable Refrigerant Flow (VRF) systems have helped add cooling to these systems. VRF systems allow for a single outdoor condensing unit to serve multiple cooling coils and even operate as a heat pump delivering effective heat even at outdoor temperatures below 0F. 

To interface a Direct Expansion (DX) coil in a UV to a VRF system, some accessory kits are needed to provide the expansion valve and the control board to effectively operate.  Depending on the UV and VRF manufacturer, additional cabinets may need to be added to the UV to house these items.  

Using MERV-13 Filters for Unit Ventilators

Another growing trend among school districts in the post-pandemic world is the use of high efficiency filters in HVAC equipment. The same goes for unit ventilators and UV Manufacturers now offer MERV-13 filters as an option. Typically, these filters can only be applied on UVs equipped with an ECM motor. 

A word of caution on using MERV-13 filters as these filters will load up faster than lower efficiency filters and require more frequent cleaning/ changing. If proper filter maintenance is not done, airflow across the coils can be restricted. This is especially dangerous in configurations with DX Coils as DX Coils require adequate airflow across them to ensure proper heat absorption and refrigerant evaporation within the coil.

A DX Coil operating with little to no airflow can result in anything from a frozen coil to a dead compressor, caused by slugging liquid back to the condenser.  Additionally, no airflow across a DX Coil can pose a threat to HW Coils downstream of it where very cold discharge temperatures can freeze that HW Coil.  This can potentially cause the HW Coil to burst and result in a flood.  It is worth repeating that high efficiency filters are a great thing, but proper maintenance is a must if they will be used.

Offerings and Arrangements

UVs with cooling coils are typically set up as a split system arrangement, but some manufacturers also offer a self-contained version for applications where a remote condenser will not be possible. The self-contained type of UVs have internal mounted compressors for cooling and can still use HW or steam heating from the building. 

Some manufacturers also offer hot gas reheat coils in these self-contained units to control humidity. The compressors used in these systems are often inverter-driven compressors which generate less noise than traditional single speed compressors. One thing to consider when using self-contained systems is that additional louver space in the exterior wall is needed for intake and exhaust air for the compressor and condensing coil.  

The various UV configurations offered as well as the option to integrate shelving and cabinets provide a seamless solution for both engineers and architects designing classrooms.  Even though Unit Ventilators are not exactly considered a cutting edge, new or trendy technology in the HVAC world, they serve a great purpose.  They provide adequate ventilation, air, heating and even cooling in today’s schools and will most likely be around for decades in the future.  To learn more about Commercial HVAC Solutions in NYC and Long Island, please visit Klima’s website and contact us today.

HVAC Training: What to Consider as a Young Upstart

Posted on by Brandon Sulikowski

Right now in 2023, there is a huge demand for professionals in the HVAC industry — and therefore a need for HVAC training. There are a lot of factors creating an increased demand for various types of HVAC needs. Across the landscape there is a lot of pent up demand for construction, some of which may stem from people’s resistance to buying new buildings with interest rates at historically high levels. 

There are major trends like electrification, increased ventilation requirements, higher efficiency standards and alternative energy all pushing for new HVAC systems and strategies. With HVAC systems typically making up around 40% of a building’s energy consumption, improvements to the HVAC systems can be low hanging fruit in a path to increased efficiency. Presently, there is a generation of HVAC professionals reaching the twilight of their career and a deficit of newcomers to meet this increased demand. So the time is right for someone to enter the HVAC field.

The 3 main types of companies in the industry

hvac training

There are 3 main paths for working in the HVAC industry. These are:

  1. Engineering consulting
  2. Mechanical sub-contracting
  3. Equipment manufacturing/sales. 

People from various backgrounds come into the HVAC industry and generally the best preparation for any of these career paths in HVAC is to have a bachelors of science in a technical field. Engineering is preferred but not an absolute requirement. 

One educational path to highlight here are HVAC technical schools, which provide HVAC training on basics of refrigeration and electrical systems. These are usually taken by people entering the mechanical contractor field, but the honest truth is that these courses should be taken by HVAC professionals of ALL pathways to get a basic foundation on how systems generally work. 

Luckily, today we have the benefit of YouTube and other resources at our fingertips. If someone is motivated enough, they can simply find the bulk of this material online. Of course, this is not as effective as being taught in a real-life classroom, but it’s better than not knowing the material at all.

Internships for students who need HVAC training

For those young people who are yet to enter the workforce and still in school, internships in nearly any business of the three industry types would be recommended. An internship is a low-pressure way to get exposure to the industry, learn some of the jargon and test out the work environment of a company with the possibility of full time employment after graduation.

Self-starters get ahead

As a young professional starting out in the HVAC field, the best thing you can do is to learn everything you can pertaining to your area of interest. For example, if you want to be a consulting engineer in HVAC, you will want to learn all of the basic principles of fans; fan curves, fan selection, troubleshooting air distribution issues, etc.

Resources for these can be found all over, which is great but can also be problematic. YouTube and other places on the internet have material, but one must be careful to learn from a reliable source. The best webinars, YouTube videos and articles come from agencies like ASHRAE, AMCA and other not-for-profit organizations. Next behind that are manufacturers who offer webinars, lunch-and-learns, and other resources. 

Start with the absolute basics to gain a solid foundation so the more complicated topics are not overwhelming. Employers will provide some pertinent HVAC training, but this will typically be limited to things related to the tasks they assign. The young professional who goes through the effort to find the resources to learn on their own will quickly get ahead in their career. Joining industry groups like ASHRAE is an easy way to not only access educational resources but also to meet other people in the industry.

Find a Mentor

Whether someone works at a mechanical contractor or a manufacturer’s rep firm, there is usually a seasoned person with a lot of experience willing to teach the younger generation — a necessity when it comes to HVAC training. More effective/useful knowledge is passed down this way than any textbook or webinar will ever provide. 

A mentor should be someone who is willing to provide informal guidance on various topics and be a trusted advisor. This is someone who can fill in the gaps to answer questions that come up from learning the basics and beyond. Some of their wisdom will be from painful mistakes they have made in their career and they are willing to share those insights and advice.

Further HVAC training education

One lesson to be learned in the HVAC industry is that the most successful people in this industry tend to be those who can combine the technical aspects of systems with business in some way. For example, if someone can understand the technical challenges of a chilled water plant, but also negotiate very well with clients they might have a bright future in the manufacturers rep world. 

Depending on what the future aspirations might be, one may find themselves taking graduate studies. One recommended graduate program would be finance. Having a master’s degree in finance provides the HVAC professional with insights into how businesses are run. This is especially critical for someone who hopes to one day go out on their own and have their own business. Understanding financial fundamentals like how to read a balance sheet and how businesses successfully manage money can make the difference between a business that survives and one that dies after a few years.

It’s not all about what you know when it comes to HVAC training

Having technical know-how is very important in the HVAC industry, but how useful is this knowledge if nobody knows you have it? Having the right networking connections in any business is vital. These connections are what may bring a new job opportunity, a new partnership opportunity or the next client for your new business. Understanding how to connect with people is a critical skill that any serious professional needs to master if they want to see substantial success.

Every contractor needs to sell their services to a client, every consulting engineer needs to work well with an architect on a project, and every equipment vendor needs to be able to work with everyone to make sure the equipment they sell successfully goes into a project. Some people have a natural ability to work well with others and some people have trouble with this. For many engineers, this may be particularly challenging. 

Those who struggle with interpersonal skills should look at enrolling in some courses like the Dale Carnegie training course. Courses like this teach people presentation skills, people skills and help with improving your ability to sell and deal with customer service. These soft skills are absolutely crucial to someone in the professional environment of any industry.

Ductless Mini Splits: What Do I Need to Know?

Posted on by Brandon Sulikowski

Ductless mini splits are an efficient way to heat and cool many homes and even certain commercial and multi-unit housing applications. They can be an effective replacement to conventional HVAC systems. Since its first introduction decades ago in Asia, mini splits have made innovative and technological changes to become an ideal solution in today’s market and growing in popularity for good reason. 

Ductless mini splits are composed of two primary components – an outdoor condensing unit, which contains a compressor and one or more indoor air handlers (the evaporators).  A conduit that houses the power cable, refrigerant liquid and suction tubing link the outdoor and indoor unit(s). All indoor units are powered by the outdoor unit single phase power. These systems require 208V/1 phase electrical power although there are some smaller 115V systems available with certain brands.

Analyzing the Benefits of Ductless Mini Splits

Cost Savings

Overall cost savings could arguably be the top reason people research and choose ductless mini splits. Ductless mini splits have some of the highest energy efficiencies in the industry. They use less energy, lowering monthly utility costs for a quicker payback. The upfront cost of installation is also typically lower than traditional systems. Precise customizable temperature settings in each individual zone create not only personalized comfort in all rooms, but also savings whether occupied or unoccupied. There are also a wide range of Energy Star rated mini splits that qualify for rebates and incentives.  

Energy Efficiency

Energy efficiency and high performance are added benefits of ductless mini splits. Inverter variable speed compressor technology uses less energy and is measurably quieter than conventional systems. Unlike conventional systems that cycle on and off, an inverter compressor ramps up or down to match the capacity needed to maintain comfort levels within the conditioned zone(s). 

Additionally, this greatly enhances the ability to efficiently dehumidify and increase air quality by running the fan longer. Ductless mini splits eliminate efficiency losses in ductwork due to leaks and conduction as well as the need to consume more energy to make up for the efficiency losses. There are models offered by some manufacturers that perform in extreme weather conditions as a reliable primary heat source. The shift to using electricity rather than burning fossil fuels like gas and oil reduces the carbon footprint, making these systems more environmentally friendly.

Ductless Mini Splits Are Easy to Install

Ductless mini splits offer design flexibility and easy installation. It can be both ducted and ductless in single and multi-zone configurations to meet the design needs. Ductless mini splits can be used in new construction or upgrade/retrofit an old furnace or heat pump system using the existing duct. It can be added to a home or business that currently does not have air conditioning or heating as the installation is much less invasive. A ductless mini split installation requires only a 3-inch hole drilled in the wall. Hence, they require little to no ductwork and often take less time to install than conventional HVAC systems. Ductless mini splits can supplement an existing system to provide additional comfort and control on room additions or remodeling projects. Smaller indoor and outdoor units ensure space-saving convenience. Moreover, models with long refrigerant piping capability can increase the distance between the indoor and outdoor units, allowing for extra design and installation flexibility.

Are There Any Downsides to Ductless Mini Splits?

While mini splits produce a significant number of benefits and value, there are limitations that need to be considered. All ductless mini splits have piping length and elevation limitations that cannot be exceeded. Typically, the largest multi zone mini split can have up to eight connected indoor units. With that many indoor units, there may be a requirement for branch distribution boxes that need to be installed indoors. Most mini split systems are only available up to 5 tons. The life expectancy of a ductless mini split is anywhere from 10 to 20 years.

Finding a Qualified Installer

Proper installation and accurate load calculations for system sizing are crucial to the potential cost savings and performance of any ductless mini split.  Finding a qualified installer and asking the right questions are a must in deciding between potential contractors. Asking how the sizing of the mini split system is determined can help qualify the experience and knowledge level of the installer as well as the amount of utility savings. If not sized correctly, it can lead to a series of ongoing issues and problems. To qualify for local energy rebates and state or government incentives and tax credits, an installer must be EPA certified and approved by certain local energy partnership programs. Knowing this information prior to installation is very important. 

Another question to ask a potential installer is if they are certified by the equipment manufacturer they intend to install. Installers are typically required to complete training classes and be certified by the manufacturer to qualify for extended warranties and install their equipment. Make sure to ask for the installer’s certificates from the manufacturer to see how current they are.  Inquire about the product warranty and the warranty process. The length of the warranty speaks volumes for the quality of the product itself. Depending on the manufacturer, warranties can range anywhere from 5 years and upwards to 12 years when registered by an approved and certified installer. 

While many homes have conventional HVAC systems, that is not the only type available in today’s market. Ductless mini splits provide a variety of benefits and values. It is an excellent, efficient, and innovative technology that can transform your home or light commercial application. Ductless mini splits are a good investment with exceptional year-round comfort and can be the ideal solution for both heating and cooling.

LG Hydro Kit: Understanding Its Benefits and Purpose

Posted on by Andy

If you’re looking for an efficient way to make hot and/or chilled water without using fossil fuels, the LG Hydro Kit may be just what you need. The Hydro Kits pair up to LG’s Multi-V condensers, providing VRF industry-leading technology and performance.  Offered in 2 different versions and several different sizes, there are a wide variety of applications that can utilize this awesome technology. So if you’re in the business of finding cutting edge solutions to complex HVAC challenges — check out this blog to see why your next project might benefit from LG’s Hydro Kit!

The Benefits of the LG Hydro Kit

LG Hydro Kit

The LG Hydro Kit is offered in 2 versions; medium temp and high temp. The medium temp version can produce chilled water down to 41F and hot water up to 122F. The high temp Hydro Kit is a heating-only unit but can produce leaving hot water temperatures up to 176F. With leaving water temperatures that close to the typical 180F target of traditional hydronic boiler systems, you can theoretically replace gas or oil fired boilers with LG VRF air source heat pumps and hydro kits.

Historically, heat pumps in the northeast were not capable of providing adequate low ambient heating, let alone a version delivering hot water over 170F.  So during those times the only alternative system that would not burn fossil fuels would be electric boilers or hot water heaters.  The electric resistance heating elements in those units generate 3414 btus/hour of heat for every 1000 watts of electrical input.

For areas with relatively expensive electricity like the New York Metro area, this is not an economical way to heat a building or home. With the introduction of new heat pump technologies like the LG Multi-V 5, every 1000 watts of electrical power is now creating double the heating output of electric resistance heating or higher (depending on a variety of factors) making operating costs very attractive compared to other sources. 

If systems like this are powered by renewable sources like solar or wind power, homes and businesses can be producing heating without any emissions or fossil fuel consumption which is great for the planet. Additionally, since these heat pumps will use half or less of the electricity compared to resistance heating they can help stretch those renewable power resources further limiting the reliance on the power grid while saving on energy costs.

Efficient Use of Interior Space

For metropolitan areas like New York City, interior space is a scarce resource in limited supply.  Traditional boiler systems have to be housed in a dedicated boiler room which eats up considerable interior space. The LG Hydro Kit is a split system type where half of the system is located outdoors and the other component is indoors. The Hydro Kit is much smaller in footprint compared to a boiler and the service space requirements are often times less than a traditional boiler. All of this leads to more usable interior space, which can be a very good thing in markets with sky-high real estate costs.

Flexibility in Design

LG Hydro Kit

The capacity offerings of the LG Hydro Kits lend themselves to a very flexible way of heating and/ or cooling a building.  The medium temp versions come in 3.5 ton and 8 ton sizes. The high temp version is offered in 3.5 ton and 6.5 ton offerings. For larger applications, multiple Hydro Kits can be installed in parallel and staged to maximize efficiency. Additionally, having multiple systems offers some additional level of redundancy over larger central plant systems.  

For multi-family buildings, domestic hot water and hydronic heating plants are often central to the building and very difficult to bill their usage out to individual tenants. With smaller Hydro Kit systems, each condensing unit and Hydro Kit can potentially be fed from each tenant’s own power meter. This eliminates the cost and responsibility of the equipment from the Landlord and can lower common charges in the rent or building fees. An additional benefit of modular systems for larger buildings is the ability to stagger system operation to reduce demand charges from the utility.  

There are several air to hot water heat pump systems offered in the market now. Many of these are what is referred to as ‘Mono-Bloc’ types where the hot water heat exchanger is outside, attached to the condensing unit.  While this may be a plus from the installation side, the downside to this is that glycol will most likely be required in the heating water for colder climates like the Northeast.  

The medium temp Hydro Kits have started to replace aging air cooled chilled water systems throughout the New York Metro area. With the modular design and flexibility of piping runs on LG’s Multi-V 5 systems, clients have ripped out their small to medium sized chillers, replaced them with LG medium temp Hydro Kits and did not have to touch their existing chilled water air handlers. These systems now offer more redundancy, lower operating cost and take up less space outdoors than previous air cooled chillers. Additionally, the medium temp Hydro Kits can produce lower temperature hot water for radiant heat systems.  

Potential Issues and concerns

While the LG Hydro Kits pack a tremendous amount of technology in a small package, keep in mind they are more complicated than a traditional boiler or chiller. Clients should make sure to find an installing contractor and service company with proper training from the manufacturer to successfully install and maintain the system for years to come. 

LG’s Hydro Kit may require more labor to install over a traditional boiler or chiller as it is a split system.  The benefits of the operational cost, environmental impact have to be weighed against any potentially higher upfront costs.

Final Thoughts on Why the LG Hydro Kit is Worth It

The Hydro Kit’s innovative technology allows for the efficient use of energy, resulting in lower electricity bills and a more sustainable future while eliminating harmful Carbon Monoxide emissions in the home or business.

With natural gas becoming more difficult to access, the LG Hydro Kit offers the best alternative over the other technologies currently out on the market. Investing in an LG Hydro Kit may seem like a simple choice when looking at all of the short-term benefits that you gain; however, when we consider the long-term environmental impact it has on our planet, this decision suddenly seems much wiser. After all, small changes such as this can have a huge impact — making the LG Hydro Kit more than worth your investment.

One tip is to regularly change out your air filters to prevent buildup that can reduce airflow and impact the air quality in your indoor environment. During the summer months, all sorts of debris can also infiltrate the equipment outside the home — from small branches and twigs to leaves, to even small animals which can chew through wiring! To ensure optimal HVAC performance, make sure there are no objects obstructing your HVAC system.

It is also crucial to schedule annual check-ups with a licensed professional to ensure that your system is running smoothly and catch any potential issues before they turn into costly repairs. By staying on top of your HVAC system’s maintenance and inspections, you can ensure that your office or home stays comfortable and energy-efficient for years to come.

How to choose the right professional technician for the job

Choosing the right professional technician for the job can be a daunting task, but it doesn’t have to be. Start by researching potential candidates online and reading reviews from previous customers. Look for someone who has experience in the specific type of work you need done, familiar with your brand of equipment and who is properly licensed and insured. Don’t be afraid to ask for references and follow up on them.

When you meet with the technician, ask questions about their approach to the job and how they plan to complete it. Make sure to get a written estimate before any work begins and be wary of anyone who asks for payment upfront. By taking these steps, you can ensure that you are choosing a qualified and trustworthy professional for the job at hand.

Warning signs that you may need to replace your unit

It’s crucial to keep an eye out for potential warning signs that you may need to replace your unit. One such indicator is if your unit is consistently failing to properly cool or heat your indoor space. Another clear sign is if you experience a major increase in your energy bills that cannot be explained by external factors. A unit that is constantly breaking down or producing strange noises is also cause for concern. HVAC systems using refrigerant to cool or heat are supposed to be closed systems, meaning the refrigerant gas should never leak out.  If your system is losing gas, that means you have a leak and it also means you are probably losing oil, which is vital to the health of your compressor.  Never let a technician tell you that they just need to ‘Top off the gas’ without finding a source of the leak.  Additionally, once the leak is found – the refrigerant from a leaking system needs to be evacuated and replaced with virgin refrigerant.  This refrigerant must match the type on the equipment nameplate. Be wary of technicians offering to use alternative refrigerants to save money.  

Furthermore, if your unit is more than 10-15 years old, it may be time to consider replacement to improve your overall air quality and system efficiency. By staying aware of these warning signs, you can address potential issues before they become major problems and ensure your unit is operating at optimal functionality.

Cost-saving strategies and tips for summertime HVAC maintenance

Summertime is the peak season for your HVAC system to function. Though it is an essential part of your business, it is also the most significant contributor to your electricity bills during the summers.

Klima’s Timeline: Analyzing a Decade of Growth

Posted on by Andy

Founded in 2011, Klima set out with an initial intent of providing customers with the wherewithal and expertise when navigating the complexities of VRF (Variable Refrigerant Flow) systems. After a decade-plus of growth, Klima has cemented itself as one of the leading manufacturing reps in New York. Here’s all about how we at Klima did it.

Klima Understood the Importance of VRF Systems

Over a decade ago, Klima solely focused on educating and selling consumers VRF systems. It was important to do so at the time, as other vendors did not provide the service that Klima has become so well-renowned for. Understanding the importance of VRF systems is crucial for achieving optimal energy efficiency and indoor comfort in commercial and residential buildings. Unlike traditional HVAC systems that operate at a fixed capacity, VRF systems dynamically adjust the refrigerant flow rate to match the cooling or heating needs of different zones or rooms, with the help of sophisticated control algorithms and sensors.

Another advantage of VRF systems is their flexibility and scalability, which makes them ideal for both retrofits and new construction projects. VRF systems can be customized to meet specific design requirements, such as high ceilings, open spaces, or multiple occupancy levels, without the need for ductwork, bulky equipment, or complex zoning controls. Moreover, VRF systems can be configured to operate in different modes, such as cooling, heating, dehumidification, or ventilation, depending on the environmental conditions and building usage.

And although VRF systems provide significant energy savings, reduced carbon emissions, improved thermal comfort, and enhanced indoor air quality, Klima eventually realized it was time to expand their product offerings. Soon, Klima began incorporating items such as energy recovery ventilators to supplement their VRF system offerings.

The Opportunity to Expand

Opening the Long Island City Office

Six years after first starting, Klima opened an office space in Long Island City. Housed with the bustling New York City market in mind, Klima offered local stock of equipment and parts for their VRF customers.  Moreover, Klima opened up a training facility for LG’s VRF systems to provide installation contractors with the knowledge and wherewithal they need to succeed in the field.

“Opening that office and warehouse in Long Island City turned Klima into a real player in the VRF game in NYC.”

Merging with AES Equipment and Acquiring iCon System Solutions Controls

The expanding product offerings weren’t the only indication of growth on Klima’s end. 2019 saw the backend expansion of Klima, as they merged with AES Equipment. This merger saw new management and, in turn, new product line offerings. As a result, Klima was able to grow its frontend employee base by hiring some of the most talented professionals in the market.

The growth didn’t stop with AES Equipment, either. In 2020, Klima acquired iCon System Solutions Controls — allowing them to expand their controls division, Klima Controls. This division specializes in providing turnkey controls systems of any size for commercial buildings.

“Merging with the guys from AES and acquiring iCon showed me what the best of the best really look like.  Having these groups become part of Klima totally raised the bar for everyone at the company.”

Opening the Melville Office

In the year 2022, the company opened a second office in Melville, which marked a significant milestone in their expansion efforts. Their decision to open a second office in Melville is a testament to their continued success and growth trajectory. The new office allowed for them to better serve their customers in the region, while also expanding their reach to new markets throughout Long Island.

Overall, Klima’s growth is an impressive testament to their dedication to excellence and commitment to meeting their customer’s needs. With their continued expansion efforts and commitment to innovation, they are well-positioned to become the go-to provider of equipment and controls for customers across New York’s tri-state area.

“During Klima’s first 10 years, the focus was only on New York City.  Not only do we have a presence there but now we have an office and training center at the best location in Long Island.  Our sign on the building on Route 110 is visible to thousands of passing motorists every day.  The Melville office is also a great environment for the employees and you feel that upbeat energy in the office everyday.”

Understanding the Benefits of VRF Systems

Posted on by Andy

Whether you’re a business owner seeking to upgrade an aging HVAC system or a homeowner looking for improved energy efficiency, you’ve likely heard of Variable Refrigerant Flow (VRF) systems. These highly advanced solutions offer unparalleled performance and comfort levels compared to conventional air conditioning units, but many may not be aware of all the benefits that come with this efficient technology. In this blog post, we’ll explain in detail what VRF systems are, how they work, and why installing one could provide significant benefits for your home or commercial building. By understanding these features and associated costs, you can make an informed decision on whether a VRF installation is right for your property.

An Overview of VRF Systems and How They Work

Variable refrigerant flow (VRF) systems have become increasingly popular in the HVAC industry due to their energy efficiency, flexibility, and zoning capabilities. Unlike traditional air conditioning systems, VRF systems use a single outdoor unit to deliver refrigerant to multiple indoor units, allowing for precise temperature control and the ability to heat and cool different areas of a building simultaneously. Each indoor unit can operate independently, adjusting its output based on the specific heating or cooling needs of its area, resulting in enhanced comfort and reduced energy consumption. VRF systems utilize advanced technology, such as variable-speed compressors and electronic expansion valves, to provide efficient and effective heating and cooling solutions. While the installation and maintenance of VRF systems may be more complex than traditional systems, their benefits make them a popular choice for commercial and residential buildings.

This means that unused areas can be temporarily turned off, reducing energy consumption. VRF systems are also quieter and more compact than traditional HVAC units, making them ideal for use in commercial buildings or spaces with limited space. Additionally, VRF systems offer precise temperature control and improved air quality. Overall, VRF technology has revolutionized the HVAC industry, providing a more cost-effective, energy-efficient, and sustainable solution to heating and cooling buildings.

Benefits of Installing a VRF System in Your Business or Home

A VRF system is a highly efficient way to heat and cool your business or home. It uses a single outdoor unit that is connected to multiple indoor units, allowing for customizable temperature control in each individual space. Not only does this increase comfort levels, but it also saves energy and reduces utility costs. Additionally, a VRF system operates quietly and has a longer lifespan than traditional HVAC systems. Overall, investing in a VRF system is a smart choice for those looking to improve the efficiency and comfort of their space.

Cost Savings with a VRF System Installation

Switching to a VRF system for your HVAC needs can bring significant cost savings to your business or home. Compared to traditional HVAC systems, VRF systems use less energy, resulting in lower utility bills over time. 

Additionally, VRF systems allow for individual temperature control in each room or zone, allowing for improved comfort and energy efficiency. Not only can a VRF system save you money, but it also reduces your environmental footprint.

Why Did Klima Rebrand?

Posted on by Andy

Since 2011, Klima New York, LLC has been a leading provider of Variable Refrigerant Flow and Dedicated Outdoor Air Systems. However, after a decade of service in the industry, it quickly became apparent that Klima was in need of a rebrand.

The rebranding includes a renewed strategy and updated digital presence, both of which reflect the company’s commitment to providing innovative climate control solutions. Klima’s dedication to quality products and customer service remains unchanged, and the company looks forward to continue serving its customers with excellence.

What led to Klima’s rebrand?

Beginning in 2022 and continuing into 2023, Klima recognized that their platform needed reworking to keep up with the ever-changing environment. As a result, they rebranded, utilizing modern technologies and forging partnerships with innovating leaders in their industry. 

Still providing clients with Variable Refrigerant Flow and Dedicated Outdoor Air Systems that will be better equipped for future advancements, Klima’s renewed focus aims to serve the same customer base while also welcoming a younger generation with open arms. 

In discussing Klima’s rebrand, President Brandon Sulikowski revealed, “Klima brought on additional ownership and management.” He further added that “The company was 10 years old and we wanted to make sure we were not alienating the younger generation of customers in the market.”

With this rebrand, Klima is able to remain trend-focused and offer their clients top quality systems so they can stay ahead of the curve.

What is Klima’s mission?

Klima has focused on rebranding in order to solidify their vision as a company. Their mission is to be a leading provider of Variable Refrigerant Flow and Dedicated Outdoor Air Systems, offering customers the most reliable, efficient and cost-effective solutions for their HVAC needs.

On the topic of their mission, Sulikowski said, “Klima’s mission is to become the #1 manufacturer’s rep firm in the New York Metro area, but we want to earn that title by building brand loyalty through customer service.”

Through their dedication to innovation and rebranding, Klima can provide customers with the highest quality products, backed by the best customer service. With their renewed focus on rebranding and customer satisfaction, Klima can help customers achieve their HVAC goals while also providing an experience that differentiates itself from other providers within this field.

Who is Klima’s target audience?

Sulikowski further added that “Klima’s target audience are the engineers, contractors and building owners with a passion for what they do in this industry.” The Klima President also noted that “We live and breathe supporting HVAC equipment and controls sales and we want customers who are dedicated to delivering the same values to their customers.”

What separates the old Klima from the new?

The rebrand from Klima to its new iteration represents a significant shift in how the company approaches its product selection. The old Klima only offered Variable Refrigerant Flow (VRF) and Dedicated Outdoor Air Systems (DOAS), but now they are taking the spotlight on rebranding and introducing much more than those two product offerings.

“The new Klima brings a wider offering of products and expertise. While the old Klima was successful with a laser-focus on only VRF equipment sales, the new Klima is taking the same customer-focused mentality and applying it to a larger variety of products and services, including controls,” said Sulikowski.

Under their rebranded identity, they have incorporated newer technologies. Their rebrand has positioned Klima as an industry leader in HVAC technology, providing unmatched energy savings and superior system performance.

In light of rebranding, Klima has implemented a number of processes and systems to ensure their customers have the best experience possible. For years, Klima has specialized in Variable Refrigerant Flow and Dedicated Outdoor Air Systems and have developed innovative solutions for these products. 

“We have made an internal shift to focus on more quality deliverables to customers and raised the bar internally on ensuring the quality of our service and project management is living up to the name we want Klima to represent,” Sulikowski stated. “The old Klima handled a lot of volume, but the new Klima will operate with more focus and attention to detail — even if that means lower volume.”

Klima’s rebrand is aimed at providing customers with an even greater experience than before, by further improving customer service, offering higher quality products, and refining their offerings to match clients’ unique needs. To facilitate this rebrand, the company has established processes and systems which will assist us with meeting the rebranded objectives of providing exceptional customer service, quality products and tailored services.

Dissecting Klima’s internal and external perception

Rebranding for Klima was not only a massive step for their front-facing appearance, but also internally. Amidst the rebrand, Sulikowski noted the differences between Klima and their competitors — as the latter tends to focus on profits over customer service and loyalty.

Sulikowski elaborated: “Our internal brand perception is that we are the good guys trying to do right by the customers while some of our competitors tend to navigate chasing profits rather than customer loyalty.”

So how does this translate externally? As Sulikowski further noted, “Our goal for our external brand perception would be for Klima to be viewed as the sales organization offering the best value and highest level of expertise in the industry. We want to be known as the company that people can trust in and rely upon for equipment and controls needs.”
