Is your furnace leaking water?

When you step into a puddle of water near your furnace, it’s an obvious sign that it is leaking — figuring out the why can be tricky. This is because there are multiple reasons for your furnace to leak water, depending on which kind of unit you have. Some of these issues you can fix yourself, while others would definitely require a professional expert. When it comes to an HVAC installation or repair service, make sure you always pick the best out of the batch.

Why is My Furnace Leaking Water?

Below, we’ll list some reasons that could cause a water leak in your furnace:

1. Water Condensation

Usually, furnace leaks result from water condensation. This is because the heating vents force the water out into your home, and it ends up puddling up on the floor. Many people experience furnaces leaking water during winter, whether the room has been heated or not. This is why you need to follow tips for furnace maintenance in winter.

Your furnace might be leaking if you see water on the floor. Other than this, you’ll notice that the furnace keeps turning on and off.

2. The Air Return is Blocked

You might notice that your furnace is leaking water due to blocked return air. There might be an air duct leading from the furnace to the outside of your house. Sometimes, the duct might become clogged with dust, resulting in unfiltered air re-entering your home. As a result, your furnace will overheat and start leaking water.

3. There’s an Obstruction in The Vent Pipe

It’s possible that there’s a blockage in the vent pipe that leads directly outside. This is why you must be aware of how your furnace is venting outside the house; it helps with detailed inspection. Otherwise, clogs could appear, leading to water leaking from the furnace. If there’s no blockage, look for symptoms of condensation near the vent or the return air duct.

4. The PVC Drain Line is Plugged

It’s possible that the water leaking from the furnace is not actually coming from the furnace at all. Perhaps, there’s a blockage in the PVC drain line. Water might drain around the furnace if the PVC drain line is clogged, as it carries the spilled water away from it. Therefore, water pooled near the furnace could be an indication of a leak.

5. The Furnace Filter Needs Cleaning

You might want to check the furnace filter to see if it needs cleaning. This is because dirty furnace filters could cause a water leak. You might need a cleaned filter. Or, in some cases, you’ll need to replace the furnace filter.

6. There’s an issue with the Condensate Pump

If the condensate pump fails, your furnace could start leaking water. In winter, water is pumped into your house, keeping the air warm. But your condensate pump might fail, causing it to work harder to get rid of the additional water. Consequently, you might notice more condensation on the floor below. Therefore, call in a professional if you notice increased water leakage in your furnace.
