Blog Furnace Is Your Furnace Leaking Water? Here are the top reasons why Key Takeaways Condensation in High-Efficiency Furnaces: Condensation forms in high-efficiency furnaces due to chilly exhaust pipe gases, typically with an AFUE rating of 90% or greater. Condensate drain lines, pumps, or traps are commonly used to direct this water vapor away from the system. Frozen Evaporator Coils: When the furnace is switched on, water can flow out of the thawed evaporator coil if it freezes. This can occur due to insufficient refrigerant levels or inadequate airflow, leading to freezing and subsequent thawing, resulting in excess water leakage. Comfort Union offers reliable furnace repair services, including emergency assistance and maintenance plans to keep your furnace running smoothly. Their team of HVAC professionals can handle everything from simple water leaks to complex system issues. 2024-05-15 // 9 min Read Asif Engineer-in-Training & Apprentice Finding water around your furnace can be a cause of concern and must be inspected immediately.

Contact Us Common Causes of Furnace Leaks - How to identify them and troubleshoot them? It is critical to act swiftly in the event that you discover water surrounding your furnace in order to avoid harm to both your system and your property. To save both time and money, it’s helpful to know what causes furnace leaks and how to fix them. 1. Condensation in High-Efficiency Furnaces Cause: The reason behind this is that condensation forms in high-efficiency furnaces because their exhaust pipe gases are chilly. These furnaces usually have an AFUE rating of 90% or greater. Condensate drain lines, pumps, or traps are commonly used to direct this water vapor away from the system.Troubleshooting:Inspect the Condensate Drain Hose: Look for leaks or obstructions in the condensate drain line. Make sure all connections are tight, and use a solution of vinegar and hot water to unclog any pipes.Examine the Condensate Pump: Check that the condensate pump is not overflowing and that it is operating properly. It may be necessary to replace the pump if it is malfunctioning.Check the Condensate Trap: To prevent water from backing up and leaking out of the furnace, check the condensation trap and remove any debris that may be blocking it. 2. Clogged Condensate Drain Cause: The condensate drain pipe might get clogged with dirt, debris, or mold, which causes water to back up and pour out around the furnace.Troubleshooting:Clean the Clogged Drain Line: If there are any clogs in the floor drain pipe, use a wet/dry vacuum to remove them. Another option for light blockages and mold removal is to flush the line with a vinegar and water mixture. 3. Faulty Condensate Pump Cause: The condensate pump keeps the water output of your high-efficiency condensing furnace to a minimum. You can experience a condensate pump leaking if something goes wrong with it.Troubleshooting:Inspect the Pump: Look for any indications of trouble while inspecting the pump. Keep an ear out for strange noises or see if the water is draining correctly. Should the pump fail to function as intended, you must replace it. 4. Improperly Sized or Installed Flue Pipe Cause: The accumulation of condensation and subsequent backflow into the furnace unit can be caused by an inadequately sized or installed flue pipe, which in turn leads to inefficient exhaust gas expulsion.Troubleshooting:Flue Pipe Inspection: Inspect the flue pipe to make sure it is the right size and that it is installed correctly in relation to your furnace. In order to keep water from recirculating, it should be slightly inclined away from the furnace. 5. Leaking Humidifier Cause: If not maintained properly, a built-in humidifier might lead to water leaking, which increases the amount of moisture around the furnace.Troubleshooting:Check the Humidifier: Look for water line leaks and make sure the humidifier is draining properly before you use it. Leaks can be easily avoided with regular cleaning and maintenance. 6. Air Conditioner Leaks During Summer Cause: When the AC unit leaks, water can collect around the furnace, which can cause problems in systems where the two units share components.Troubleshooting:Check the AC Drain Pan and Line: Verify that the drain line is unobstructed and that the drain pan is not cracked. As needed, fix or replace the pan. 7. Cracked Heat Exchanger Cause: Thermomechanical stress and heat can cause the heat exchanger to break with time, which in turn allows water to flow out.Troubleshooting:Professional Inspection: Due to the complexity and potential safety issues with a cracked heat exchanger, it is recommended to have a trained HVAC specialist examine the system - whether it is your primary heat exchanger or secondary heat exchanger. 8. Frozen Evaporator Coils Cause: When the furnace is switched on, water can flow out of the thawed evaporator coil if it freezes.Troubleshooting:Check Airflow and Refrigerant Levels: Make sure there's enough refrigerant and adequate airflow in your system. To avoid air filter restrictions or blockages that can cause freezing, change them periodically. 9. Overflowing Drain Pan Cause: Excessive condensation or a lack of regular emptying of the furnace's drain pan could cause the pan to overflow, which would be a problem if the furnace had one.Troubleshooting:Regular Maintenance: Especially during times of heavy use, make sure to check the drain pan frequently and remove any debris that may have accumulated there. 10. Blocked Air Filters Cause: Condensation within the furnace might become worse if the air filter is unclean or clogged, which restricts the passage of air and causes other problems.Troubleshooting:Filter Replacement: To maintain adequate circulation and avoid condensation buildup, you should change the air filter in your furnace on a regular basis (at least every three months).
