CONDENSATE DRAIN

Residential central air conditioning systems that need to cool and dehumidify use a condenser, evaporator coil, and refrigerant piping to operate. The means of moving the air might differ (furnace, air handler, etc.), but the principal is the same for all split systems. The term "split" refers to the physical separation of the condenser and the evaporator. This is in contrast to a window or wall air conditioner in which they are "packaged" together. The refrigerant is compressed and run through a series of tubes to remove as much heat as possible, then piped to an evaporator coil as a warm liquid. Expansion of the compressed liquid causes it to cool, and as the air passes over the coil, heat is extracted. The cool liquid becomes a cool gas as it gathers heat from the air, and is drawn back to the compressor to start the procedure again. As the air passes over the evaporator coil and cools, moisture in the air condenses and drains off as condensate. Thus, water out your drain line. Make sure you see water coming from your main drain. If it is coming out of your emergency drain, then you know your main drain is clogged and should call us.
