What’s the difference between a commercial HVAC system and a residential HVAC system?

While commercial and residential HVAC systems serve a similar purpose of heating, ventilating, and air conditioning, they vary considerably in mechanism and features.

This is mainly because cooling and heating needs for homes do not match that of commercial centres.

There are considerable differences between the commercial units and residential units that ultimately tell them apart. First, they have different sizes. Compared to commercial HVAC systems, residential HVAC units are much smaller in size. Commercial units also have condenser fans, thermostats, evaporators, compressors, dumpers, and blowers. They also have different energy consumption needs as both need different amounts of energy to serve other areas. The placement for the units differs; while residential HVAC systems are usually placed outside your home, a commercial HVAC system is typically placed on building tops or in swamp coolers for various reasons. First, HVAC systems positioned on the rooftop create great space-saving solutions. Second, rooftops minimize noise pollution inside the building, and third, it’s the perfect spot for maintenance as no activity will be disrupted during replacements and repairs. The two units also have differences in mechanisms. Manufacturing and installation of commercial HVAC systems are modular, while residential systems are manufactured as standalone systems. Due to the modular nature of commercial systems, all the components are housed together, allowing easy maintenance and upgrade. Residential units have split parts between the outdoors and the indoors, making it difficult to modify or expand them. In essence you can not install a commercial HVAC system in your residential apartment.
