Air conditioners create condensation as a by-product, and it’s easy to ignore the drainage because it’s largely out of sight. As the humid air from your home blows over the cold evaporator coil inside the blower compartment, the humidity condenses and needs to drain into your home’s plumbing or outdoors. But A/C condensate drain problems can affect your health and cause serious damage to your home.
The air conditioner is one of the most favorable spots for mold growth. The blower fan pulls air rich in organic particles into the air conditioner, feeding the mold. The evaporator coil provides plenty of moisture to support its growth in the condensate pan and drain pipe and even inside the air ducts. Mold can also cover the evaporator coil, dramatically reducing system efficiency. Spores from mold may also trigger allergies, asthma or more serious health problems.
The drain trap keeps gases from backing up into the blower compartment, and if it dries out, you may notice noxious odors. It’s more common after the A/C has been off for a prolonged period and requires professional attention to repair.
A/C condensate drain problems that involve leakage or flooding are caused by blockages in the drain pipe or cracks in the drain pan. Undetected problems can cause an expensive repair to the area where the blower compartment sits, causing floor damage, wood rot and possibly rust the blower compartment.
Avoiding Drainage Problems
When an HVAC professional performs annual system maintenance, he or she will clean the drain pan, check the trap and clear the condensate drain pipe. In the meantime, homeowners can pour bleach down the drain pipe, or use a wet vac to pull the blockage out. To prevent issues, inspect the drain pan periodically and clean the end of the drain pipe periodically.
