Why is furnace leaking water

Water damage is serious and effects other areas of your home including the ceiling, walls, and flooring. Mold is an issue as well. This is one of the most common reasons for a furnace leak. Many furnaces run at a high efficiency , which means an AFUE rating of either 90 or above. This type of furnace contains two heat exchangers that help it produce more heat. Condensation caused by the production of heat must get carried out of your home via pipes.

Most of the time this is through a floor drain. Another reason for your furnace leaking water is a break or clog in the humidifier. These devices are hooked up to your plumbing system in order to add moisture to the air. If any type of breakage occurs, or they get clogged, water will start dripping around the furnace. There actually may not be an issue with the components of the furnace, which is a good thing.

However, the leak still needs to be addressed. When a clogged or broken plumbing pipe causes a backup in the drainage system, it seems as though the furnace is leaking. These pipes need to be repaired or replaced. Many times this causes the coil to freeze. However, sometimes it causes water to leak and pool up around the furnace. In mild climates like California, furnaces and air conditioners are sometimes used during the same season.

Using a water-safe vacuum i. Afterward, turn on air conditioning system and monitor to determine if this fixed leak. If condensate pump does not react, it indicates a mechanical failure.

If it does pump the water, then the drain line from pump to drain or wherever water gets dispersed is clear. Sometimes these issues require a quality contractor to disassemble air conditioner and furnace components to diagnose.

Overtime, your outdoor air conditioning unit will get covered in dirt and possibly cottonwood.

High-efficiency furnaces extract heat from the combustion gases for a longer period of time than a standard-efficiency furnace does, causing the gases to cool, then condense.

The condensation is routed to a floor drain. If the cause of the leaking water is condensation, there are a few possibilities. You might have a clogged condensation drain or tubing, a break in the condensation line, or issues with the condensate pump, if you have one. A standard-efficiency furnace extracts some heat from the combustion gases and quickly vents them out the exhaust or flue pipe. If you have a condensation leak with a standard efficiency, then its exhaust or flue pipe may be incorrectly sized.

There should be no water involved with a standard-efficiency furnace. If he or she rules out a condensation leak, there are other possibilities, all still requiring a professional. One option may be an issue with your whole-house humidifier, if you have one connected to the furnace. It could be leaking inside your furnace, though having an annual maintenance appointment on your HVAC system should prevent this from happening.

Another possibility is an internal drain system clog.
