Reasons For Water Leaking From Your Furnace

A furnace is necessary for heating in most households when the cold season is in full gear. Unfortunately, malfunctions can lead to water seeping from the heating appliance. As such, you may notice puddles of water below the furnace, hindering its performance. Failure to address the leaks promptly may escalate and cause water damage in your home. Thus, you should contact a heating system repair technician to inspect your system and fix the cause of leaks for optimal performance. The following are the reasons for your appliance leaks water.

Condensation Leaks

Some furnaces, especially high-efficient ones, generate condensation in their normal operation. This is because the heat exchangers absorb so much heat that the flue gas transitions to a liquid state. Subsequently, the condensate line channels the water to your drainage system. However, if the condensate line deteriorates over time, water will escape through the tiny holes. Moreover, dirt and grime can accumulate in the drain line, preventing water from flowing out. As a result, water will back up in the tubing, causing it to overflow and drip below the furnace.

Wrong Size of Exhaust Pipe

Your furnace will burn gas and generate heat, water vapor, and flue gases such as carbon monoxide and nitrogen oxides. Since these gases are toxic, the flue pipe vents them outside, away from your house. However, if you install the flue pipe yourself, you may fail to size it correctly. Further, you may install a small flue pipe that cannot accommodate combustion gases from your system. Ultimately, this leads to the condensation cooling down and flowing back into the flue pipe, leading to water leaks. Therefore, you should hire an expert for your exhaust pipe installation, ensuring no obstructions.

Faulty Condensate Pump

A condensate pump will collect and disperse water from the furnace condensation. Unfortunately, you may notice whistling noises when the pump sustains an air leak. Additionally, dirt could clog the pump, leading to gurgling noises. As a result, a faulty condensate pump will cause water to back up and leak below the furnace. Thus, it is wise to employ heating services to fix your condensate pump for effective water drainage.

Broken Humidifier

Cold air holds less moisture than warm air, making a humidifier necessary during winter. However, debris can clog the humidifier over time, leading to water seepage. Moreover, excess pressure from the water supply source can damage your device, causing it to leak water. Therefore, you should engage a heating specialist to replace your humidifier, ensuring the right water pressure. Moreover, they will clean the drainage pipe for excess water to flow out effectively.

Note that water leaks from your heating appliance can affect your home and promote mold growth. Given this, hiring a heating repair contractor is crucial to service your unit regularly for peak functionality.
