Close up of furnace

 

There are some furnace issues that can be baffling, and a leak is certainly one of them. Most people don’t realize that their furnace even handles water, so discovering a leak is odd. While you can inspect your furnace and look for the source of the leak yourself, it is best to call a professional to get confirmation and a proper fix. The list below will help you find the issue so you can better inform your HVAC technician about your concerns when they arrive.

1. Nearby Leaks

First things first: is the furnace leaking or is it something else? Just because there is water near the furnace doesn’t necessarily mean it is the cause. It is possible that the wall has sprung a leak and caused water to pool around the base of the furnace. Or nearby appliances like washing machines and air conditioners could be the cause. If you can see where the leak is coming from, that will help you find the source.

If you’re not sure, an HVAC technician can help you locate the source and help you determine which professional you should be calling for the fix, if they can’t handle it themselves.

2. Condensation Leaks

So the water is coming from the furnace. What now? If you have a condensing furnace leaking water, the source is usually from the condensing unit. Condensing furnaces are also called high-efficiency furnaces and they have very good energy-efficiency ratings. Any part of the second heater and condensate system in the furnace could be the source of the leak, so you will need a professional’s help.

3. Humidifier Issues

If the furnace is leaking water when the heat is on, and it is equipped with a whole-home humidifier, then the humidifier could be the issue. Humidifiers use water, of course. It has at least one drain line for water and most also have condensate pans or some way to expose your furnace’s warm air to the moisture it needs. Problems with this system might include leaks and clogs, but your HVAC technician can take care of them.

4. Exhaust Problems

Water in the furnace exhaust is a common problem. The exhaust vent needs to lead outside to allow the exhaust to leave your home. When installed improperly, it may end up allowing some of that outside moisture in. Or, exhaust vents that go through the attic may get exposed to roof leaks and then bring that moisture down to your furnace. Your HVAC technician will want to examine the whole vent and see where the problem is.

When your furnace is leaking water, most people want to call the professionals and ensure it is handled properly. If you’re in this situation, reach out to the team at Lambton Climate Care for help.
