Furnace Cleaning

The main parts of a furnace are: the blower motor which forces air through the duct system and coil assembly which cools or heats* the flowing air (heatpump units only*).
When the motor's blades are dirty and/or the coil assembly is clogged, it will reduce the quanity of air circulating through the entire duct system. This causes dramatic loss of efficiency of the entire system up to 60%. The heating and cooling bill may double, the blower motor life will be reduced, and motor oil will be mixed with dust which will circulate through the duct system. The sign is black (oily) stains on vent covers or on sorounding ceiling or floor areas. A plugged coil assambly will create mold, mildew, and bacteria nests.
