Common Condensate Drain Issues

September 22, 2016 | Blog

Common Condensate Drain IssuesIf you have ever felt the unpleasant drip of water from your ceiling when it wasn’t even raining, there is a good chance you know what a clogged condensate drain is. If not, here’s a quick overview of how a condensate drain works and how you can avoid clogs and overflow.

Your condensate drain is part of your overall HVAC system. When you’re running your air conditioner, you get cool air from the system blowing air over your chilled evaporator coils. The cold from the coils brings the temperature of the air down, but it also dehumidifies the air, forming condensation.

This water falls into a drip pan. A drain line runs from it to some point outside your home. The drain line is intended to remove the condensation safely so that it doesn’t cause water damage. However, like most drains, it can get clogged. When that happens, water overflows the drip pan. If left long enough, the water will spill over the sides of the pan, creating water damage and leaks.

It is much simpler to avoid drain clogs than it is to clean up after them. So how do you keep these blocked drains from happening?

Let’s take a look at what blocks the drains and how to prevent it:

  1. Dust and debris. When you get dust, pollen, and other particles in your air system, some of them will be caught in the condensate drips that occur as your air cools. It’s impossible to keep all dust and other particles out of your air system. However, regularly cleaning your filter can help reduce the number of particles significantly. This means less debris in your drain and fewer chances for it to clog.
  2. Mold and mildew. Pipes that stay wet, especially with cold or room-temperature water, are the perfect breeding ground for mold and mildew. Overgrowth of these pollutants can clog your condensate drain pipe. Flushing it out as part of your yearly maintenance check-up can prevent clogs.

Great company. Contacted my current AC company to check on my warranty before charging me anything. Saved me a bunch of money and headache if dealing with anything. Would definitely recommend them and use them again.
