The efficiency and lifespan of a unit is directly related to the cleanliness of the condensor (outdoor)
coil and the evaporator (indoor) coil. The indoor and outdoor coils becoming dirty is a natural occurrence under normal
run conditions, but if left untreated, this will cause the compressor to be under a much greater strain.
~What causes the indoor and outdoor coils to become dirty?
The outdoor coil becomes stopped up
with scaling and small dirt particles while the indoor coil becomes covered with mold, mildew, lint and dust. Mold also
grows in the primary drain pan, making its way to the drain line.
~What are the consequences of allowing a unit to remain dirty?
During warm, humid months,
this mold and mildew can grow at a rate fast enough to stop up the drain line, causing water to run into the
unit, damaging electrical components, and run over onto the ceiling, damaging insulation and sheet rock. If
the unit is under the house, mold can cause moisture damage in the crawl space.
While in air condition mode during Summer months, as the coils become dirtier, the indoor coil picks up heat at a much slower rate and
the outdoor coil expels that heat at an equally slower rate. Also, the compressor
runs at a higher pressure, which shortens its life and causes it to use more energy, resulting in higher energy bills.
~What can I do to protect my unit?
Money spent on preventive maintenance is money saved on energy usage and replacement of a shortlived compressor.
Killman Heating & Air conducts a 21-point inspection and cleaning, which includes chemically cleaning and
treating both the indoor and outdoor coils and treating drain pans and drain lines to prevent stoppages that cause
water damage. The absolute key to a unit running as efficiently as it did at installation is keeping the indoor and
outdoor coils clean. This allows the compressor to operate at factory specified pressures, which will allow
the unit to provide lasting comfort for you and your family for years to come.
