There are various types of HVAC systems, including the two major types, residential and commercial HVAC systems. Residential HVAC systems are typically used in homes and possibly small businesses. Commercial HVAC systems are used in office buildings, large retail stores, warehouses and other large buildings.
A commercial HVAC system is much larger than a residential HVAC system. This visible difference doesn’t need too much explaining. Bigger buildings need bigger HVAC systems because of the amount of space they need to serve. They’re also more complex in terms of dampers and thermostats.
Due to the size difference and the size of the areas they both serve, the amount of power differs as well. The commercial HVAC system needs a much higher level of power to function.
