Causes Of Water Leaks In Your Furnace

This article will talk about the probable reasons your furnace is leaking. Likewise, it will discuss the steps you can take to resolve it.

Condensation Leak

The heating process of your furnace includes the formation of condensation. These droplets travel through pipes and are drained into a pan. However, with a condensation leak in the furnace,  your furnace will have damaged or blocked pipes. Consequently, the water is not drained properly and instead leaks out of the furnace. If this is the case, you will see water pooling at the base of your furnace.

Clogged Furnace Filter

The furnace filter traps dirt, dust, dander, and other contaminants. It helps keep your indoor air quality level high. However, it can get clogged over time, and it will not work as it should. Also, air cannot flow properly. As a result, the coils will freeze, and pipes can get clogged. The latter will cause leaking, which is evident when you notice puddles of water around your furnace. Make sure to check the furnace filter regularly. Clean or replace it as needed to prevent this problem.

Plumbing Leak

If you suspect that your furnace is leaking, check your plumbing system. There might be clogged parts or broken pipes in the plumbing that are causing a detrimental effect on your furnace. These issues will trap water and debris, and the drainage will back up. You will notice a leak at the base of your furnace when this happens. If your plumbing system is leaking, have a professional inspect it so that they can resolve the issue right away.

Humidifier Leak

A humidifier keeps the air from drying out. It produces moisture to ensure that the air in your home is comfortable. The humidifier can be connected to your heating system. If there is a leak, it could be due to a leak in the humidifier. The humidifier leak could trickle onto the furnace, so it looks like the heating system is leaking.


Air Conditioner Leak

If you are using your AC system with your heating system and there is a leak, the cause might be your cooling system. The water from your AC is drained into the condensation pan. When the pan becomes full, the excess water could leak onto your furnace. The water then drips out of your furnace, so you might mistake it to be a furnace leak when it actually is an AC leak.

Heat Exchanger Problem

When you have checked all possible reasons for the leak and still haven’t determined the cause, you might have a leaking heat exchanger. If this is the case, the component needs repair. If the problem is more severe, you might have to replace your furnace. Contact a licensed professional HVAC company immediately to help you.

What to Do When You Notice A Furnace Leak

If you suspect a furnace leak, contact a licensed HVAC technician to schedule a furnace checkup as soon as possible. Listed below are a few things you can do while you wait for professional help to arrive:

  • Turn off your furnace right away. If you cannot find the power switch, you can shut off the heating system via the breaker.
  • The furnace base should be kept as dry as possible. You can use a mop or rags to absorb water that has leaked from your furnace. If possible, you can use a wet-dry vacuum as well. Doing this will ensure that water damage is prevented.
  • Check the furnace filter, especially if it hasn’t been cleaned or replaced for a while. Replace or clean a dirty filter immediately.


Hire A Furnace Repair Professional

Never conduct a DIY furnace repair when you are experiencing furnace problems. A professional HVAC contractor has been through extensive training and has years of knowledge to work on your HVAC system. On the other hand, most homeowners do not have the skills and training needed. You might cause more damage to your unit, and you’ll only end up paying more as well.

It is always recommended that you call a professional HVAC technician instead of a handyman. HVAC techs have the training and certifications to repair or replace your system. Keep in mind that your furnace is a specialized appliance comprised of complex components. Therefore, it is always better to have a licensed HVAC technician to conduct proper inspections and repairs to your system.
