What Do I Do about Excessive Condensation Issues with my Air Handler? - Ask the Expert Episode 223

Today's question is from Dino. "Hi. I bought a 3.5 ton Goodman heat pump from you a year or so ago for a 1,300 Square foot house we remodeled. In the attic is where the air handler is located. The system cools great but I am having excessive condensation problems and I am reaching out to you for some advice into this and I would appreciate any help. Thanks."

When you have an air handler, a heat pump, or an air conditioner, and you've got excessive condensation problems with the air handler, that usually means the condensate drain pan or tube is not getting the water out. If the water isn't draining properly from the air handler, there are usually one of two issues.

  • The drain hose or the pan could be clogged somewhere. Just check and see if there is a bunch of stuff gunking up the drain hose.
  • It could be because your drainage isn't angled downward properly. Most condensate drains are gravity drains, which means that the gravity is just pulling the water down. This could happen if it's installed incorrectly. In that case it could be that the drain pan is overflowing.

You can try to fix this problem yourself. But if everything seems normal and you can't find a clog then you will probably need a professional to come out to take a look at it.

    I have the same problem, same size equipment and house. My installer re-used the old drain pipe, I finally ran drano through it to make the problem stop. The copper pipe was also reused and has a pinhole so I also have the problem of replacing the pipe and coolant to deal with.
