Your HVAC system works hard to keep your home cool and comfortable, but there's a hidden part of your system that can cause serious problems if neglected: the drain line. Recently, during a routine service call, we cleared out a drain line and found quite a mess—check out the picture below of our shop vac filled with water and debris we pulled from the system!
What Grows in HVAC Drain Lines?
Over time, drain lines can accumulate all sorts of debris:
Mold and mildew: The constant presence of moisture provides the perfect environment for mold to thrive.
Algae: Given enough time, algae can start growing in your drain line, leading to clogs.
Dirt and debris: Dust, dirt, and even leaves can find their way into the drain line, especially in outdoor units.
Why It’s a Problem
When your drain line gets clogged with this gunk, it can lead to water backup in your system. This could cause:
Water damage inside your home, including leaks and stains on ceilings or walls.
System shutdowns due to safety features kicking in when water isn't draining properly.
Mold growth in and around your HVAC system, which could lower your indoor air quality and pose health risks.
The Importance of Regular Maintenance
This is why we recommend HVAC maintenance twice a year. Cleaning your drain line, checking refrigerant levels, inspecting your system for any signs of wear and tear—these are just a few of the steps we take to ensure your system runs smoothly all year long.
Don’t wait until your drain line looks like our shop vac! Stay ahead of the problem with regular maintenance. Call CoolAir MD today to schedule your next service.
