Your leak could be a result of the condensation tubing becoming clogged or from breaks in the line.

Old gas furnace leaking water. If this is the case it s best to call your local furnace repair team. If you have a standard efficiency furnace usually 15 plus years old it should not be leaking water. Go to the furnace and open the drain line. Why a condensing furnace leaks water unlike conventional furnaces condensing units are actually designed to produce condensation.

But if you have a high efficiency furnace here s the most common cause. This is especially significant if your furnace is connected to a drain since the floor will be sloped gently to encourage runoff. Then apply pressure to the line to blow it out. There are a few things that could be happening here.

If this is the case it could be an incorrectly sized flue pipe which is making water to drain back into the furnace. Broken condensation line condensate pump. This is one of the most common reasons for a furnace leak. Many furnaces run at a high efficiency.

Typically the condensation from a high efficiency gas furnace is channeled to a floor drain. Find the end of the drain and use a shop vac to suck the pipe clean. Plumbing leaks can occur along the ceiling pipes causing water to drip down onto the furnace or the floor nearby. Possible causes of leak again the most common reason for a leaking furnace is a condensation leak.

Reasons for a furnace leaking water condensation leak. As your gas furnace runs is there water leaking at the base. The condensation is routed to a floor drain.

A standard efficiency furnace which has a metal exhaust pipe should not have condensation. It could also be a result of the floor drain becoming clogged. Another reason for your furnace leaking water is a break or clog in the humidifier. There are a few ways to do this.

You see instead of venting away combustion gases quickly like a conventional unit a condensing furnace pulls a lot more heat from those gases before allowing them to vent away into the atmosphere.
