Furnace leakage is a problem that homeowners commonly encounter. Water leaking from your furnace could cause mold growth, damage your property, and even pose a health risk. Let’s take a closer look at the possible reasons behind a furnace leaking water and what you can do to remedy the issue.
Problems with the Condensate Pump or Drain Line
Condensation occurs when a highly efficient furnace releases exhaust gases. The condensate drains to a condensate pump or a floor drain. A malfunctioning pump or blocked drain can result in a furnace leak.
Clogged Filter
A clogged filter is a common cause of furnace leakage. A dirty filter makes your furnace work harder to move heated air through your home. This could make condensation collect around your filter. The condensation will eventually leak onto the ground.
Humidifier Issues
Furnace leaks can also occur due to humidifier issues. If your system has a built-in humidifier, it will need plumbing to deliver water. A leak may occur if the water lines break or clog up because of poor maintenance.
Malfunctioning Heat Exchanger
Calcium carbonate can clog the secondary heat exchanger. When this happens, you may see condensation on the floor.
What to Do When Furnace Leakage Occurs
If your furnace is leaking water, take the following steps:
- Turn the unit off using the furnace switch, the thermostat, or at the breaker. That stops water from continuing to pool around the unit.
- Clean up the pooled water using towels and napkins. You may need to use a wet-dry vacuum if there’s a large amount of water.
- Check your air filter and replace it if it’s dirty or clogged.
- Call an HVAC professional to diagnose the issue and repair the system.
Furnace leakage can have more severe consequences if left unchecked. Make sure you have your system fixed before it causes more expensive repairs. If you need HVAC repair, maintenance, or indoor air-quality solutions, contact Ace Hardware Home Services, proudly serving the Dayton area.
