What Should I Do If My Furnace Is Leaking Water?

What Does Water Have To Do With My Furnace?

If you’re like most homeowners, you may wonder how water is even connected to your heating system. In fact, moisture is the enemy of most HVAC processes, so it can be confusing at first to figure out why water is leaking in the first place. The answer lies in the type of furnace that you have.

Non-Condensing Furnaces

Standard efficiency furnaces don’t create water or moisture when they heat your air. The combustion process warms the heat exchanger, allowing air to absorb the heat as it passes by. Any byproduct of the combustion process is expelled outside via the flue. Standard efficiency furnaces are recognizable by their metal exhaust pipe leading outside.

Condensing Furnaces

High-efficiency (or condensing) furnaces operate a little differently. The combustion process occurs the same way, but when the byproduct is expelled along the flue, it goes through a secondary heat exchanger. As the air undergoes a second heat exchange, it is condensed. The moisture turns from a vapor to a liquid as it heats, creating water. High-efficiency furnaces that have condensers have white PVC flue pipes to carry moisture away from your home.

What Causes A Furnace To Leak?

First and foremost, if you have a standard-efficiency furnace, it can’t leak water. A puddle of water underneath your unit has to come from a different source — likely another appliance nearby.

However, high-efficiency furnaces can experiences malfunction in the condensate lines and components that cause the water being carried away to leak back into your home. Some of the most common sources of water leaks in these furnaces include:

  • Clogged condensate drain hose
  • Leaking inducer assembly
  • Damaged or clogged condensate drain line
  • Clogged condensate trap
  • Leaking condensate pump
