Why is Furnace leaking water in winter?

The creation of condensation is a standard process within the function of a furnace. If the drain becomes clogged at any point, this means condensation will collect in the condensate pan and overflow. This causes your furnace to leak water. In winter, a frozen pipe is a common cause of drainage pipe clogging.

Do furnaces drain water?

Most furnaces will have at least 2 internal drains, typically one for the heat exchanger and one for the vent, usually at the inducer outlet or on the inducer housing. All condensate drains go into a trap. The condensate trap is absolutely mandatory for a high-efficiency gas furnace.

What causes a furnace to leak water?

Again, the most common reason for a leaking furnace is a condensation leak. If the cause of the leaking water is condensation, there are a few possibilities. You might have a clogged condensation drain or tubing, a break in the condensation line, or issues with the condensate pump, if you have one.

What happens when furnace drain is clogged?

The more water that your system extracts from the air, the more water will drop down into the pan, and the more your pan will fill up. Eventually, a completely blocked drain line will cause the water in your drain pan to overflow, resulting in potentially catastrophic damage to your home.

Why do high-efficiency furnaces drain water?

High-efficiency furnaces create water because they have two heat exchangers, one more than a conventional furnace. The two heat exchangers absorb so much heat that the exhaust gas changes from a gas state to a liquid state. Condensation forms and then drains out through the condensate line.

How much water should drain from furnace?

HomeTips.com says a high-efficiency furnace can produce as much as 5 or 6 gallons of water from condensation each day. Most of the time, condensate pipes are set up to carry condensation outdoors through a hole in an exterior wall. The water is able to drain harmlessly into the ground.

How much does it cost to fix a leaking furnace?

A furnace gas line leak repair cost is between $500 and $750 on average. If you smell gas, leave the house immediately and call for emergency service right away because this is extremely dangerous.

What happens if a furnace gets wet?

Water that comes from HVAC leaks and flooding can cause serious damage to your system. It can get into your pipes, ductwork, furnace or air conditioner. Unchecked water can short your electrical components or can cause harmful corrosion.
