Why it’s Important to Keep the Condensate Line Clear and Clean

The condensate drain is one component that no one thinks about until there’s a problem. This passive part is responsible for draining all of the moisture that’s released by your air conditioner. When your evaporator coil absorbs heat and cools the warm air it receives, a significant amount of condensation develops. Depending on the ambient humidity, your air conditioner can remove more than 5 gallons of water each day. If your drain line is clogged, this moisture can back up in your home.

Potential Problems

Although the condensate line is usually a passive gravity-powered drainage system, several things can go wrong. Over time, algae, mold and microorganisms can clog the pipe that transports water out of your home. Usually, this common problem can be prevented or corrected by flushing the pipe with a product that will break down these organisms. This is one of many maintenance services that we perform at Assurance Heating & Air Conditioning. To prevent problems, always ask your air conditioning technician to complete this task.

Water Damage and Humidity Problems

In extreme cases, water may back up in the collection pan. After some time, it could overflow and damage your attic, ceiling and furnishings. This can also happen if water pools on one side because the pan isn’t tilted correctly. Many homeowners in Illinois have a split HVAC system with an outdoor compressor, indoor evaporator and an air handler that’s used by the air conditioning system and possibly the furnace. If this is the case, water will build up inside your home, which can increase indoor humidity, make your home uncomfortable and cause water damage.

To see if your condensate line is functioning properly, locate the drain pipe on the exterior of your home, and check to make sure that water is trickling out on a humid day. If you want to help your system run better, you can complete this and other DIY tasks. You’re also welcome to contact us at 847-388-0316 to learn more about seasonal maintenance requirements.
