There can be a few reasons why water is coming out of your furnace. It is vital to troubleshoot and identify the cause to get it fixed! This blog post will go over some of the most common reasons for water coming out of furnace. Keep reading to learn more.

Damaged Drain Pan

Many people have their furnaces regularly serviced to protect against leaks, but even with this precaution, it is not uncommon for the water to appear around the furnace. In most cases, this is due to a damaged drain pan. The drain pan is designed to catch any water that condenses inside the furnace. However, water will leak if the drain pan becomes cracked or full of holes.Simply replacing the old drain pan with a new one should stop the leak. In some cases, cleaning or replacing the furnace’s condensate pump may also be necessary. Either way, addressing a damaged drain pan should solve the problem and help keep your furnace running smoothly.

A Frozen Coil

A furnace is a common household appliance that is used to generate heat. The heat is then distributed throughout the home using a system of ducts and vents. A crucial component of this system is the furnace coil, which helps to transfer heat from the furnace to the ducts. If the coil becomes frozen, it can cause water to leak out of the furnace. It is because the ice prevents the heat from being transferred properly, causing the water to condense on the cold surface of the coil. Sometimes, this can also cause the furnace to overheat and shut down. If you notice water leaking from your furnace, it is vital to have a professional inspect the unit as soon as possible.

Clogged Drain Line

We all expect our furnace to blow hot air, but it is a cause for concern when it starts blowing water instead. If you have noticed water pooled around your furnace or even dripping from the vents, there is a good chance that your drain line is clogged. The drain line is responsible for carrying excess water away from the furnace; if it becomes blocked, that water has nowhere to go but out. Fortunately, unclogging a drain line is usually a relatively simple process. Start by locating the clean-out plug at the base of the furnace. Then, use a plunger or plumber’s snake to clear any debris causing the blockage. Once the line is clear, run hot water through it to flush out any residual gunk. With the drain line clear, your furnace should be back to blowing hot air in no time.

Failed Condensate Pump

If you have a water leak from your furnace, your condensate pump has likely failed. The condensate pump is responsible for pumping water out of the furnace and into the sewer line. When the condensate pump fails, water can leak out of the furnace and onto the floor. If you suspect that your condensate pump has failed, you should call a furnace repair technician to have it repaired or replaced. In the meantime, you can try to prevent water damage by placing a bucket under the leak to catch the water.

So, what do you think is the cause of your furnace leaking water? Have you tried any of these solutions? We are here to help, so do not hesitate to reach out if you have any questions or need further assistance. Until then, keep your home warm and cozy – and dry!
