How is a Commercial HVAC different from a Residential HVAC?

Commercial and residential HVAC systems work under the same fundamentals in most aspects. However, they do have several differences with regard to multiple functionalities. This is why it is critical to look for technicians specially trained to handle commercial HVAC repair near me. There are very few technicians trained in handling both residential as well as commercial systems. Always look for technicians that have ample experience in the field.

The base differences between these system variants come from the fact that the commercially used systems are created to serve a sizable structure & larger collection of people. This requires a complex and large system architecture as compared to its simpler counterpart available with the residential systems.

So, how exactly are these two systems different?

Let us break it down for you!

What is the difference between residential and commercial HVAC systems?


The first and foremost difference between the two systems is the location. In general, the residential HVACs are placed down on the ground. However, the commercial HVACs are typically planted over the roof for the proper flow of air throughout the commercial building. This is due to the fact that residential systems aren’t as bulky as commercial systems. So, placing the commercial HVAC on roof ensures that the machinery doesn’t take up much space. Not just that, placing the system on the top avoids any chance of vandalism.

However, placing the system on the rooftop simply doesn’t mean you are done with it. There are several factors, such as airflow, shade, circuit connection, and so on to take care of. If you aren’t up for the task, you can always rely on the services provided by experts for commercial HVAC repair near me.

2-Modular vs. Standalone:

A residential HVAC system is a single and self-contained unit that doesn’t require expansion or modification in any way. However, on the contrary, the commercial systems tend to be modular systems that can easily be modified as per the requirement of the building. If the existing unit is unable to cool down the entire building with proper flow, you might require to add some more parts to make things more functional.

If you are unable to decide the right way to place your unit, it is imperative that you seek help by searching for professionals for commercial HVAC repair near me.

3-Split vs. Packaged:

Almost every residential HVAC system comes with components that are placed indoor as well as outdoor. The indoor unit is designed to bring in the cool or hot air and spread the same throughout the room. The outdoor unit is designed to carry out all the critical functionalities while keeping the uncomfortable air away from the house. On the other hand, commercial units are sold as single cabinets known as the packaged unit.


The residential systems generally use single pan for condensation needs, and the very same pan usually drains out through the pipe. This is due to the fact that residential HVAC system is concentrated on a small space, which leads to minimizing condensation. However, the complete drainage system focused on commercial ventilation systems tend to be complex. This is because the units are focused on cooling or heating a much larger space, which means the condensed output will surely be much higher in amount.

If you have been experiencing a leak in the commercial drainage system, you can always seek help from experts for commercial HVAC repair near me.


Commercial HVAC requires the use of multiple components for proper ventilation. This is due to the fact that the commercial buildings lack proper amount of windows to enable proper ventilation. In the case of a residential system, there isn’t much need for ventilation as the windows are enough to get the job done in a perfect way. However, it is imperative that you keep the windows closed when the HVAC system is under operation. This ensures maximum efficiency for the system.

6-Maintenance Costs:

The entire cost of a system depends on how complex it actually is. Size is secondary, but complexity is what decides how much you need to shell out from the pocket to avoid any repair charges. For your commercial unit, you need help from a skilled and highly-experienced technician, which might surely cost you a lot. However, you can always look for service providers that keep the cost budget-friendly without compromising on the quality.
