An Inside Look At System MaintenanceExpect us to do a complete system operation check in both cooling and heating modes. If you have a heat pump, we should check the defrost operation, as well. All other major components and safety devices should be checked. The air conditioner’s coils, both indoors and out, should be cleaned, as well as the indoor blower housing and blower wheel. Most modern residential air conditioning and heating fan motors have permanently-lubricated bearings so no additional lubrication is needed.
All of our residential air conditioning systems produced after 1990 have a direct drive blower, which means there are no fan belts to inspect. However, if you have an older system with a fan belt, be sure to have the fan belts checked and replaced if needed. Your duct system should also be checked. Inefficient operation can be caused by return air leaks located in non-air conditioned spaces like attics or crawl areas. Hot or cold air is drawn in through the leak, which is then heated or cooled by your system. This decreases your system’s ability to heat or cool your home and increases your energy bill, as well.
Pre-Season Preventive Maintenance Check ListWe recommend all maintenance and service work be performed by a professional air conditioning and heating dealer that holds the appropriate credentials to install and service air conditioning and heating equipment. Let your friends and relatives help you paint or cut grass if they feel the need to help around your home.
