Minneapolis-St. Paul Forced Air Furnace Repair
“Why is my furnace leaking water?” It’s a question we get asked a lot.
Homeowners like you need reliable and working heating.
So if you find your furnace leaking water, you will be understandably dismayed and concerned.
Discover a few reasons why your high-efficiency gas forced-air furnace is leaking water and what to do.
1. Leaking Condensate Pump
One possible source responsible for your furnace leaking water is a faulty condensate pump.
The condensate pump is a small sump pump, draining water away that is created during the heating (or cooling) process. Some homeowners also have a humidifier unit attached to their furnace that requires water drainage as well.
In some cases, you’ll need to clean the condensate pump and its associated tubing needs to remove buildup and gunk. To clean the pump we recommend adding 1/2 dixie cup of bleach to the pump storage tank. In other cases, the pump has stopped working completely and it needs to be replaced.
You need a working condensate pump so that water does not collect outside or inside the furnace, potentially harming your home.
You should call a qualified HVAC company if you suspect you have a problem with a leaky condensate pump.
We can repair or replace the pump, and also inspect your furnace for water damage.
2. Leaking Humidifier
Many high-efficiency gas forced-air furnaces (AFUE rated > 90%) have an attached humidifier unit with a water line connected to it. This distributes moisture into the heated air that is pushed into your home when your furnace is running.
Sometimes the humidifier leaks into or around your ductwork, this will cause you to think the furnace is leaking. You need to contact a reputable heating and cooling company to repair or replace a faulty humidifier unit. This prevents further damage to your furnace.
3. Clogged Floor Drain
When you don’t use a condensate pump the condensation from your furnace is usually routed to a floor drain.
Sometimes the floor drain, and / or condensation tubing leading to the drain is clogged as well. Check for a break in the line, which will probably be the cause of your furnace leaking water.
