Heating, Ventilation and Air Conditioning (HVAC) Inspection

With a hot, humid climate the greater Houston area has to offer, we all want our air conditioning system to keep us cool and comfortable. That is why the HVAC system is an important part of a complete property inspection. Texas licensed inspectors are not allowed to use gauges on refrigerant lines to check refrigerant levels of the system, but there are other ways I inspect an air conditioning system for proper operation.

Operate cooling system for about 10-20 minutes and then check the temperature differential between supply and return air systems; the differential should be about 15-20 degrees. Remove equipment access covers intended for inspection purpose on the outdoor condensing unit and indoor evaporator could reveal hidden deficiencies, including a dirty evaporator coil. Checking for air leakage with the duct system would reveal inefficiencies with the system, which lead to longer equipment usage and higher utility bills. Corrosion and liquids in evaporator auxiliary pan could reveal an obstruction to the primary condensate drainpipe. Proper access to all equipment should be provided for inspection and safety of service technicians.

While not as frequently in use for the greater Houston area, the heating system is important as well. The only way to inspect for a cracked heat exchanger in a gas-fired system is removal of the heat exchanger, which Texas licensed inspectors do not perform. Again, there are other ways I inspect the heating system for proper operation.

Operate system to observe the gas flame inside equipment and use of electronic gas detection equipment for any evidence of gas leakage within the system. Operating the system can reveal deficiencies with controls or fan motor and removal of equipment cover could reveal hidden deficiencies. Proper access to equipment should be provided for inspection and safety of service technicians.
