Is your furnace leaking water? Leaks are a common issue with furnaces, so we’re pretty sure some time during the time spent in your home, you will experience one. There are numerous reasons why a furnace leaks water, and we’ve outlined four of the most common reasons below:
- Condensation leak: This is a generally a problem for those with high efficiency furnaces. These types of furnaces contain two heat exchangers that help it produce more heat. Condensation caused by the production of heat must get carried out of your home via a set of pipes. When these pipes clog or break, you’ll get a leak around the base of the furnace.
- Humidifier leak: If you have a humidification unit installed inside your furnace there is a chance that it may be the source of your furnace leak. Have a professional HVAC technician take a look at the problem and make a proper diagnosis.
- Clogged filters: If your furnace’s filter is dirty and clogged, it will restrict airflow to the furnace coil. This may cause it to freeze up completely, or simply allow water to pool up at the base of the unit. Always check your filters on a regular basis to ensure maximum furnace efficiency and avoid water leaks and other damage.
- Heat exchanger damage: A problem with the heat exchanger inside your furnace could be the source of your water leak. If this is the case, you’re in for a major repair as the entire unit will have to be replaced.
Whenever you spot a leak around your furnace you should act quickly to have the problem repaired. Shut off your furnace, clean up the water around the unit, and call an HVAC technician
to help you properly diagnose and fix the problem.
