Homeowner Handbook: What is a condensate line?

You may have heard your condensate line referred to as a few different things — a condensate drain line or a condensate drain. At MTB we’re heating and cooling experts, and we want to share a few of the ins and outs of your HVAC system so you can make qualified decisions. 

The condensate line is an integral component of your system and does numerous jobs. The most important is ensuring your HVAC system drains excess moisture outside of your home. While this is critical year-round, it’s especially critical during the summer months when you’re running your AC heavily. 

When your HVAC system cools the air, humidity is released, and it turns into condensation. Traditional condensate lines are usually PVC or metal and utilize gravity to lead the drainage out from your HVAC unit through an exterior wall to the outside, where it will evaporate into the air.  Many newer homes have the condensate lines terminate in the washer drain box, which then runs to the sewer lines.

The importance of your condensate line cannot be emphasized enough. It keeps the inside of your home moisture free. Moisture is the bad guy — it can be the downfall of your system and lead to problems like mildew. 

As a homeowner, it’s important to get the experts to inspect your HVAC system and condensate line. If your condensate line gets clogged with dust or dirt, this can impede its ability to funnel water outside. Wondering how to tell if your condensate line might be clogged? A lot of newer HVAC systems will automatically shut off when water begins to back up, meaning your AC is turning on and off without adequately cooling your home. EZ traps — or safety switches — can also be installed to help prevent issues with potential water problems.
