Why Is My Furnace Leaking Water?

Have you noticed a puddle of water around your furnace? A furnace leaking water is never a good sign, but often it’s not quite as bad as you might think when you first notice the problem. Here are some potential reasons you may be noticing water around your furnace, and what the Black Diamond Plumbing & Mechanical team recommends you do about it.

1. Water from a Clogged Drain

If you have an air conditioner, then the furnace and air conditioning system share an internal drain. Sometimes, that drain can get clogged. When that happens, water from the air conditioner gets redirected through the furnace, and you may notice what appears to be a leak. Unclog the drain, and the leak should disappear.

2. Leaks from Condensation

Energy efficient furnaces create more condensation than older models. That condensation can collect at the bottom of the furnace. While it should drain away or collect in the condensation pan, sometimes the drain process doesn’t work as it should or the pan gets full, and you end up with a puddle on the floor. This is not a serious problem, because condensations is normal and healthy.

3. Humidifier leaks

Does your HVAC system have a built-in humidifier? Humidifiers use water from your home’s plumbing to ad moisture to the air. If it has a clog or crack, it can look like water is coming from your furnace. Check the humidifier first for signs of a leak before moving on to other problems.

4. Pipes Leaking Near the Furnace

If you have any plumbing pipes near the furnace, then check these for signs of a leak. Again, if these are leaking and the water is directed into or near your furnace, it could cause a leak that looks like it’s coming from the furnace.

5. Heat Exchanger Problems

If none of the first four problems are the cause of your water, then the secondary heat exchanger could be the source. This is a costly repair that must be handled by a professional. If you can’t pinpoint the cause of your problem, then give Black Diamond a call to have your heat exchanger inspected!
