Water leakage from furnaces is a common problem, yet it can often be challenging to determine the cause. It can be especially troublesome, as the reason can be difficult to identify, and the water damage can be severe.
In this article, we will explore how to identify the common causes of furnace water leaks and the proper Daikin furnace repair solution.
What Causes Furnace Water Leaks?
The most common causes of water leaks from furnaces are clogged drain lines, blocked condensate drains, and faulty drain pans. Other causes include a cracked heat exchanger, a faulty humidifier, and water line leaks.
Clogged Drain Line
A clogged drain line is one of the most common causes of water leaks from furnaces. In this case, the clog has likely prevented the water from running out of the furnace, causing a pressure buildup inside the system that eventually causes water to leak out.
Resolution: A technician can use specialised tools to clear the blockage in the drain line. The technician can also inspect the interior of the drain line with a camera to ensure it is free from blockages.
Blocked Condensate Drain
The condensate drain line allows excess water from the furnace to flow out safely from the unit. If the drain line is blocked, the water will build up and eventually cause it to back up and leak.
Resolution: To resolve this issue, a technician must unblock the drain line. This can typically be done by using plumbing snakes or other tools to remove the obstruction.
Faulty Drain Pan
The drain pan, also known as the condensate pan, is where the water collects before it is piped out of the furnace. If the drain pan is cracked or damaged, water will leak out of the furnace.
Resolution: A technician must replace the damaged drain pan and ensure it is adequately sealed to prevent further leaks.
Cracked Heat Exchanger
The heat exchanger is a metal component of the furnace that transfers heat from the air being blown out to the air being drawn in. If a crack develops in the heat exchanger, water can escape out of it and into the home’s living areas.
Resolution: If a crack is found in the heat exchanger, a technician must replace it.
Faulty Humidifier
The humidifier is a device used to add moisture to the air and is connected to the furnace. If it is not working properly, it can cause water leaks from the furnace.
Resolution: A technician will have to inspect and properly reset the humidifier. It may also need to be replaced if it is too damaged.
Water Line Leaks
If the water lines connected to the furnace are not correctly sealed, water can escape and cause a leak.
Resolution: The technician must inspect the water lines and ensure they are properly sealed.
Conclusion
Furnace water leaks can be a severe issue, as they can cause damage to the home. It is crucial to identify the cause of the water leakage to ensure that it can be properly resolved. In this article, we explored the common causes of furnace water leaks and how to fix them.
