Why Is Water Coming out of My Furnace in Avon, NC?

A leaking furnace can result in water damage in your basement or room where you have your furnace. A leaking furnace needs inspection to identify the problem. Below are some of the causes of a furnace leak in Avon, NC.

Condensation

High-efficiency furnaces come with a cool exhaust, and they produce condensation. If your heating system comes with a white plastic pipe, then yours is probably a high-efficiency furnace and will produce condensation. If the condensation tubing clogs and/or breaks or the condensation drain blocks, your heating system will likely leak.

Standard-efficiency furnaces that come with a metal exhaust pipe don’t produce condensation. If they do, then the heating system’s flue pipe is the wrong size.

Broken Secondary Heat Exchanger

Secondary heat exchangers are components of high-efficiency furnaces. They collect heat that would otherwise go to waste and use it to heat your Avon, NC, home. Gases in the exchanger cool and form water.

Leaks from the secondary heat exchanger means the exchanger has a problem, and this may necessitate a costly repair or a new furnace. Contact a service technician to inspect your heating system.

Leaking Humidifier

A built-in furnace humidifier may have cracks or holes or may clog. When this happens, the humidifier lets out water that then pools in your heating system. Humidifiers use water to create humidity in your furnace.

The water flows in and out of the humidifier to add moisture to the air in your Avon, NC, home. Simple cracks and holes in your humidifier can cause pools of water in the furnace.

Clogged AC Condensate Drain Line

If you have a heat pump and it only shows signs of leaking when the AC is on, then the problem is most likely the condensate line. The AC coils produce condensation through the refrigeration process. This moisture leaves your system through the drain pan and condensate line. If this drain line clogs, there will be a leak in the surrounding area.

A professional can help you detect where a leak comes from and fix it. Call R.A. HOY Heating & Air Conditioning in Avon, NC, to inspect and maintain your furnace and other components of your HVAC.
