Never Call a Residential Technician to Repair Commercial HVAC Systems

One of the major red flags Union-Bulletin writer Sheila Hagar pointed out involved the inspection process. A local appraisal company recommended a home inspection company to search every nook and cranny of the building for problems, which the county hired. However, county officials failed to realize that residential and light/heavy commercial HVAC systems are different.

According to Michael J. Brandemuehl, professor and Professional Engineer from the University of Colorado Boulder, commercial heating and cooling systems have more hardware in place than a typical home system. It’s fairly easy to spot the difference because residential HVAC systems are normally not configured as rooftop units.

Residential systems may use a ground-based unit, but commercial systems may use more than one unit due to increased heating and cooling loads. It doesn’t take much to realize that most office buildings clearly have more rooms to heat or cool than a typical home.
