Why Is Your Furnace Leaking?

To stay comfortable throughout the year, you need a heating and cooling system. When something goes wrong, try to determine the cause so that you can take steps to stop it from spreading. A quick diagnosis and furnace maintenance could prevent a heating outage or a potential need for a Brownsburg furnace repair company in the future. The following are some reasons why your furnace is leaking and tips for fixing it.

Damaged or Blocked Condensate Lines

During operation, high-efficiency furnaces create moisture. As the heat exchangers pull warmth from the fuel source, the fuel cools enough to turn from a gas into a liquid. In most cases, this liquid is piped out through a drain line, which can wear out over time, get punctured, or become clogged with debris or ice.

Check the exterior side of the drain if water is collecting inside. It is possible for the condensate to freeze, plugging the pipe as it exits in harsh weather. Inspect the floor drain next to the furnace and clean away any debris or dirt clogging its trap. Water may be leaking out before it reaches the drain if the condensate line has been punctured. To have the line repaired, contact a furnace maintenance contractor.

An Ill-fitting Flue Pipe

In conventional non-condensing furnaces, moisture is vented outside while it is still a gas. Find a metal vent pipe attached to the side or top of the unit. Water leaking from around this flue means gasses are trapped inside due to oversized or improperly shaped vent pipes. Have an HVAC professional inspect the unit and replace the incorrect flue with one of the correct sizes.

Often, the furnace and air conditioner are located together. Check the drainpipe if the AC has been running recently. This is usually located next to or on top of the furnace.

Humidifiers connected to heating systems could also cause leaks. A clog in the furnace’s lines may look like water coming from the air conditioner or humidifier, but it could actually be coming from the furnace. Identifying the leak’s source is the responsibility of a technician experienced in heating and air conditioning systems.
