By the same principles that cause a cold glass of tea to sweat on a hot Louisiana day, A/C systems produce gallons of water due to condensation forming on the cold evaporator coil. The condensate drainage system easily conveys the water from the drip pan to the floor drain or outside the home. However, if there are A/C condensate drain problems, you may find a puddle of water there or at the indoor air handler.
Condensate Drainage System Basics
The condensate pan collects dripping water from the evaporator coil. The water flows into the drain pipe, runs through a trap like the one under your sink and empties to a floor drain.
As you're likely aware, water and moisture invite mold and other microorganisms. In fact, condensate dripping from the evaporator carries a multitude of bacteria and debris to the drainage system, which can cause blockages if the A/C isn't regularly maintained.
Following are some of the A/C condensate drain problems and causes of troubled systems:
- Water spillage – The most common drainage problem is a clogged trap caused by mold, algae and debris. A clogged trap or pipe quickly causes water accumulation and spillage inside your home if backup drainage measures are malfunctioning. For example, if the overflow pan is rusty or cracked, water spillage occurs.
- Mold contamination – The evaporator, fins and drainage system parts are havens for mold, fungi and algae growth. These microorganisms re-circulate through the ducts and home. This may be indicated by musty, foul odors.
- A/C shuts down – If overflow components are working properly, the float switch will trigger the A/C to shut down in the best case scenario. However, you'll need to call your HVAC technician to get the system up and going again.
