Preventative Maintenance

Preventative Maintenance or PM as it is known in the industry, should be performed semi-annually.  Your investment in HVAC equipment is substantial and the investment warrants maintenance in the same manner as you would maintain your automobile.  Maintenance includes chemically cleaning the condenser coil, checking the high voltage to ensure that it is within specification, checking the low voltage control system, checking the energy consumption, checking the starting electrical system, inspecting the filters, checking the refrigerant charge, and visually inspecting the system.

Over time your system becomes less efficient as a result of reduced heat exchange in the outdoor.  A dirty coil will not exhange heat properly because the dirt acts as insulation.

Dirt on the condenser coil prevents the heat exchange from taking place.  This makes the compressor work harder with higher than designed head pressures.  Adding refrigerant to a dirty system is likely to result in an overcharge of refrigerant.  The excess refrigerant can make its way to the compressor, where there compressor will fail when it encounters liquid instead of vapor.

A system that is cleaned will run at reduced amperage draws, the system will run more efficiently as a result of increased heat exchange at the condensing unit, and the compressor will run for shorter cycles which results in reduced energy costs.
