Is a Drain Line Causing Problems with Your HVAC System?

If you have problems with your HVAC, it could be because of any one of a host of problems. A common problem for an HVAC to stop working is a simply a clogged drain line. If your drain line is backed up, it can trigger a sensor that turns off the HVAC system until the line is cleared.

Your HVAC drain line’s purpose is to remove condensation that develops with the unit’s evaporator coils. The HVAC drain line moves moisture down and out of the house. You can see the moisture on the outside of your home.

The drain line is the small, narrow pipe that has a slow drip of water trickling from it when the AC unit is on or has recently been on. From time to time, the drain line can get clogged.
