One of the most prevalent problems with HVAC systems is furnace water leaks. It can create quite a mess in your home and a major problem for your furnace unit. While it is great to have a system that is so flexible, it also means that there are more chances for things to go wrong.
Heating, ventilation, and air conditioning are complex systems that rely on multiple moving parts to function optimally. So, it is never a good sign when your furnace starts leaking water. In most cases, you need to call a furnace repair specialist to fix the problem. In this feature, let us discuss the various sources of leaks that might happen to your furnace. Then you would know what to do when they happen and when to call a furnace repair specialist.
Reasons Why a Furnace Leaks
Different furnaces can have water leaks for different reasons. Read on to learn more about its possible causes and what you should do when water leaks from your furnace.
Heating, ventilation, and air conditioning are complex systems that rely on multiple moving parts to function optimally. So, it is never a good sign when your furnace starts leaking water.
High-Efficiency Furnace Condensation
A high-efficiency furnace creates condensation as a byproduct of its operation. Unfortunately, this condensation can sometimes escape from the system. It can either cause damage to the tubing or a clog in the floor drain. The most effective way to prevent this is to have your furnace regularly serviced by an HVAC maintenance professional.
Remember that condensation should only happen with a high-efficiency furnace and not with a standard-efficiency one. However, if there is still condensation, it is necessary to contact a certified HVAC technician right away.
Secondary Heat Exchanger Malfunction
Water leaks in furnaces can also come from the secondary heat exchanger. A secondary heat exchanger is often where the combustion exhaust goes after leaving the primary heat exchanger. This process creates water vapors that can cause leaks. Regular furnace cleaning helps prevent this issue. During routine upkeep, an HVAC technician can detect if there is a leak before it turns into a bigger problem.
Leaking Furnace Humidifier
Another potential source of your furnace leak is the humidifier on the unit. Humidifier leaks can happen for various reasons—from scale control insert blockage to water backup in the drain line. But then again, regular maintenance can help prevent bigger problems. Likewise, with the help of an expert technician, they can detect a leaking humidifier before it becomes a major issue.
Clogged Condensate Trap
Condensate traps play an important role in removing corrosive condensate from high-efficiency furnaces. However, a clogged trap can restrict condensation flow. Thus, causing it to build up and overflow out of the furnace. Meanwhile, another problem can arise when the condensate drain line gets broken or disconnected, leading to furnace leaks.
External Furnace Leaks Source
Your furnace leak may be coming from an external source. A leaky water line above your furnace, for example, can cause it to seem like your furnace is leaking. Or, if your furnace is located in an attic, a roof leak could have the same effect. Only rule out possibilities once you have investigated thoroughly.
