Reasons For Furnace Leaks

In this article, we discuss the causes of furnace leaks, some furnace troubleshooting tips, and what you can do to address the issue.

HVAC Condensation Leak

Condensation forms during the heat process of your furnace. These droplets are drained through the pipes or a floor drain. If the pipes get clogged or damaged, the water will leak out of your heating system instead. You are likely to see water pooling at the base of your furnace if this is the case.

HVAC Humidifier Leak

Is your humidifier connected to your HVAC system? If so, check your humidifier. Humidifiers generate moisture to keep the air from becoming too dry. Any humidifier issues can lead to a leak in your furnace, which might be the reason for the leak in your furnace.


Air Conditioner Leak

If you use your AC system and furnace simultaneously and there is leaking, the cooling system might be the cause. Condensation in the AC is drained into the condensation pan. When it is full, water can drip into your furnace. As the water is leaking out of your heating system, you would mistake the leak to be coming from the furnace instead of your A/C.

Plumbing Leak

A plumbing system leak negatively affects your furnace. Any clogged parts or damaged pipes in the plumbing system will clog water and debris. As a result, the drainage won’t be able to flow correctly and will back up instead. You are likely to see a leak at the base of your furnace if this is the case. Contact a professional to have your plumbing pipes inspected and repaired or replaced right away.

Clogged Filter

The furnace filter collects dirt and dust so that you can enjoy a high level of indoor air quality. However, it can get clogged over time. Air cannot flow properly when this happens. Your system might have frozen coils or clogged pipes. The latter can cause leaking, and you will notice a water puddle around your furnace. Make sure to check the filter and clean or replace it when needed.

Heat Exchanger Issue

When you have checked everything else and still cannot find the leak’s cause, it is time to take a look at your heat exchanger. Unfortunately, heat exchanger leaks can be severe, and the repair is typically expensive. If there are severe damages, you might even need to have a new unit installed instead. This can be serious and costly. Discuss the issue with your local, trusted technician so you can have the best possible solution to your heat exchanger problem.

Steps To Take When You Notice A Furnace Leak

Contact a reliable furnace repair company when you notice any leaking from your heating system. While you wait for help to arrive, here are a few steps you can take:
Shut off your furnace immediately. If you cannot locate the power button, switch your furnace off via the breaker.

The furnace base should be kept dry as much as possible. Use a mop, rags, or a wet-dry vacuum to remove water. This way, any water damage to your home and system is prevented.

Check the furnace filter, especially if it hasn’t been cleaned or replaced lately. If it is dirty, clean or replace it immediately.

Hiring A Professional Heating Repair Company

Never conduct DIY repairs on your furnace if you have not undergone the proper training to do so. Unless what needs to be done is as simple as filter replacement, it is not recommended to service your system yourself. You might cause more harm than good if you do not know what you are doing. You might even end up having to spend hundreds or thousands of dollars on HVAC repairs and replacement.

Your HVAC system is a piece of specialized equipment comprised of complex parts. Therefore, avoid calling your neighborhood handyman as well. It is best to contact a professional furnace repair technician to repair, diagnose, and resolve all your heating system problems. An HVAC expert has the right tools, training, experience, and knowledge to ensure that all furnace services are done correctly and on time.
