Differences Between Commercial and Residential HVAC

Life without HVAC systems would be extremely difficult to say the least. Can you imagine working in 30 degrees Celsius with no air cooling or trying to sleep in your bed while your home is -2 degrees Celsius with no heating? HVAC systems are an important part of residential and commercial properties, and serve the standard function of ventilating, heating, and cooling. However, the two systems differ in their respective mechanisms that are strategically designed to serve the space they are built for.

If your property is equipped with an HVAC system, keep in mind to only hire specialized contractors to perform the necessary installation and maintenance. Additionally, due to the significant differences between commercial and residential HVAC systems, expertise in home air conditioning does not transfer over to systems in commercial buildings. Finding an appropriately trained professional is necessary to ensure the longevity and high performance of your HVAC system.

Variations between commercial and residential HVAC

Size and Compatibility

The two HVAC systems greatly vary in sizes. Commercial buildings ideally have larger spaces compared to residential properties and accommodate more people at a time. Heavy-duty commercial units are built to provide heating and cooling for a large number of people. In contrast, residential HVAC systems are more compact and cater to a smaller amount of people.

Installing an HVAC unit in accordance with the size of your property is essential. If the system is too small compared to the area it is operating to heat or cool, it will constantly run and overwork itself in an attempt to reach the thermostat settings. On the other hand, if the machine is too large, it will reach the temperature settings in smaller cycles and fail to eliminate inside humidity. The two scenarios can take a significant toll on the machine and impact its longevity.

Commercial HVAC units, unlike residential systems, are also too big to be placed on the side of the buildings. They are situated on the rooftop instead.


Commercial HVAC systems have both heating and cooling combined into an individual unit. Whereas residential HVAC machines consist of two prime components: an outdoor compressor and an indoor evaporator. Commercial units are intact but it’s comprised of intricate parts that require thorough maintenance.

Bigger HVAC systems are also bound to use multiple thermostats to maintain temperatures in different parts of the building. Many modules in commercial units give property owners the liberty to reduce or increase the air conditioning capacity of the system, depending on the people it is set to accommodate.
