Reasons Why Your Furnace Is Leaking Water

Water leaking from a furnace is a common issue for homeowners. As follows, a water leak from your furnace could result in costly repairs.  Or, worse, mold growth, which could damage your property and endanger your health. Thus, if the leak persists, your furnace will eventually fail and need to be replaced. Furthermore, if you’re having trouble with a furnace that won’t turn on, you may learn more here.

Why Is My High-Efficiency Furnace Leaking Water?

First, condensation is formed when the exhaust gases from a high-efficiency furnace are released. Thus, when condensation is unable to drain correctly, it causes a water leak.

Below, our Sacramento HVAC technicians share a couple of examples.

Condensate Drain Hose Leaking

The drain hose that slopes down from the PVC exhaust pipe is quickly blocked with debris, dirt, and dust. As follows, this occurs leaks occur when any tubing that aids in draining is damaged, disconnected or obstructed.

Leaking Inducer Assembly

Additionally, condensation flows down the exhaust/flue pipe, down the condensate drain hose, and into the inducer assembly. Water can seep out of the furnace if the inducer component is cracked.

Condensate Drain Line Leakage

A condensate drain pipe is used to remove the water as it exits the system. Water leakage can occur if something has a loose connection, cracks, or holes. In addition, if the drain line becomes clogged, the condensate might back up and cause a water leak.

Why Is My Low-Efficiency Furnace Leaking Water?

If your furnace unit is a standard-efficiency furnace, it will not produce any water. If there is standing water surrounding your furnace, it is most likely the result of another piece of equipment.

The Air Conditioner Is Leaking Water

When your air conditioner is turned on, it generates water, a major source of leaks. Your air conditioner may leak for a variety of reasons, including:

Drain Pan Damage

A primary drain pan is situated beneath the evaporator coil in all AC systems. In addition, some air conditioners include a secondary drain pan located beneath the unit. The drain pan’s purpose is to catch any condensate. Excess water will spill or seep out if there is a crack or hole.

Drain Line Obstruction

If water cannot move through a clogged drain line, the drain will disengage from the drain pan. The water will then trickle and pool around your air conditioner.

Condensate Pump Failed

First, to drain the condensation from the HVAC, you must have a condensation pump. Therefore, if you have a high-efficiency furnace, the stove and the air conditioner often share the condensate pump.
