Designing and installing an HVAC system for your property takes specialized knowledge and training. As a result, it’s not advisable to hire an unlicensed contractor to install your new HVAC system.

A professional will have the required certifications and licensing, as well as the right experience in designing and installing various types of HVAC systems. However, you may be wondering why it’s important to hire professionals for your HVAC installation.

An HVAC system is responsible for regulating temperatures, airflow, and air quality in your home or office building. It’s composed of various pieces of equipment and components, such as a condensing unit (Outdoor Unit, also known as the A/C Unit), a heat exchanger (Indoor Unit, also known as the furnace or a fan coil).

The compressor is located inside the outdoor condensing unit and is used to pump refrigerant through the system. The condenser is the large outdoor fan coil we all think of as the AC, and the evaporator coil is found inside the building, is typically attached to a gas furnace, or is part of the indoor air handling equipment.

The compressor's job is to constantly pump refrigerant throughout the refrigeration circuit, from the outdoor fan coil and back into the building, where the indoor fan and evaporator coil are located.

The evaporator coil is used to change the liquid refrigerant into a vapor gas before it returns back to the outside compressor where it can continue to cycle the refrigerant from a liquid state as it enters into the evaporator coil (The indoor section of the AC), changes its state into a vapor gas while inside the evaporator, and then pulled back into the compressor in its vapor state to be cycled all over again.

Refrigerant phase change can only be achieved if the equipment has been installed properly. Even something as simple as a dirty filter can prohibit the capability to achieve these refrigerant phase changes from a liquid to a vapor gas. This is why maintenance is so important.

The goal of your HVAC system is to maintain consistent temperatures inside your building. During summer, it needs to keep temperatures low to prevent your building from getting too hot. During winter, it needs to keep temperatures high to prevent your building from getting too cold.

So, Which HVAC Company Should You Choose?

The choice of which HVAC contractor to hire for your commercial HVAC installation is a big decision. You’ll be relying on them for years to come, so you want to be sure that you’ve made the right decision. The best way to select an HVAC contractor is to conduct an in-depth review of their company.

Start by searching online and looking at reviews from customers who have hired the HVAC contractor in the past. You can also contact the Better Business Bureau to figure out if they have any complaints or issues on file. You should also speak with the HVAC contractor directly to find out if they have the skills and experience needed to complete your project.

Ask them about their experience installing commercial and/or residential HVAC systems, as well as the certifications and licensing they have. You can also ask about the process they follow for installing these HVAC systems.

If the contractor that you are interviewing doesn't use the word 'COMMISSIONING' then it's best you keep interviewing contractors until you find one whom does mention this topic and also goes on to explain the meaning of a system commissioning to you, and why its an essential final confirmation of whether or not the equipment had been designed and installed in such a manner that the new setup should operate effectively for 2 or more decades.

The contractor should be able to provide you with proof that the system vitals were tested, and logged and fall within the equipment manufactures specified test result ranges which are within an acceptable range.

You’ll Get an Energy Efficient System

When it comes to HVAC installation, you’re likely to find two types of systems: Central air systems and Ductless VRF or Mini-split Systems. Both types offer many benefits, but central systems are not nearly as energy efficient, as their ductless counterpart. If you’re trying to reduce your building’s carbon footprint, going with a multi-zoned VRF or a heat pump ductless system is the way to go.

Ductless systems do reduce energy costs, but they also significantly increase indoor pollutants. Central systems, on the other hand, reduce carbon emissions by up to 60% while maintaining high indoor air quality. Central systems do this by sucking out your building’s stale air and replacing it with fresh air. This results in a much healthier environment for your employees and customers.

It’s a Long-term Investment

If you’re investing in a new HVAC system for your property, you’re making a long-term investment. You’ll want to be sure that you select an efficient HVAC system with a lifespan that exceeds your business’s operating duration.

A reputable HVAC contractor will install a system that’s capable of running for decades. They’ll make sure that the components are of high quality and are built to last. When you go with an HVAC contractor that’s more interested in making a quick buck than providing you with a quality product, you might end up having to replace your system much sooner.

You’ll Receive a Higher Quality Installation

When it comes to commercial HVAC installation, it’s essential to work with an experienced contractor. A contractor that’s been in the business for years has probably installed a variety of HVAC systems.

| 2023They’ve also encountered all kinds of issues, both common and rare. As a result, they’re more prepared to deal with any issues that arise during your HVAC installation. They’ve likely seen every possible scenario and know how to deal with it.

Contractors that are inexperienced with commercial HVAC installation, on the other hand, are more likely to make a mistake. During installation, for instance, an inexperienced contractor might not use the proper tools.

They might also make mistakes with the wiring, which can lead to dangerous situations. An experienced contractor, on the other hand, knows exactly what they’re doing. They’ve done it hundreds of times, and they’ve seen just about everything.

It Ensures Code Compliance

When you hire an HVAC contractor to install a central HVAC system, they’re responsible for ensuring that it meets code compliance. They’ll make sure that your system complies with all applicable building codes and standards. Without proper code compliance, your system is unlikely to work as intended.

If your HVAC system isn’t working properly, it can lead to unsafe working conditions, poor indoor air quality, and lower productivity. It can also result in expensive repairs. If your HVAC contractor is not properly ensuring code compliance, it could lead to serious problems down the road.

A responsible HVAC contractor will use their expertise to make sure that your system stays up to code. They’ll also use the latest research and technology to make sure that your system runs as efficiently as possible.

Pro HVAC Installers Are Licensed and Bonded

All states, except Wyoming, require commercial HVAC contractors to obtain a license. A license shows that a contractor has the required experience in the field and has taken the necessary training courses.

If you hire a contractor without a license, you’re taking a huge risk. They may not have the skills or knowledge needed to complete the job correctly. They might also be less reliable, as they don’t really have anything to lose.

A contractor with a license, on the other hand, has a lot to lose. In addition to a hefty fine, they may have to surrender their license. You should also make sure that any experienced HVAC contractor you hire is bonded. A bond is a type of insurance that protects you in the event that your contractor doesn’t finish the job. A bond also protects the contractor.


Hiring a highly-qualified HVAC contractor is the best way to ensure that your new system is installed correctly and performs efficiently. An HVAC contractor with years of experience will make sure that your system complies with building codes, is energy efficient, and lasts for decades.

This is a long-term investment that will generate significant savings in the long run. If you’re looking to install a new HVAC system in your home or commercial building, make sure to choose a reputable contractor.

Start by conducting an in-depth review of their company, and then ask them the questions. You can also ask other contractors for advice on which HVAC contractor they recommend.
