Why Your Furnace Could Be Leaking 

Discovering water beneath your furnace is a homeowner’s worst fear. Is it a furnace issue or plumbing malfunction? It could be either, but Stevenson Service Experts is here with some HVAC issues that could result in a leaky furnace. 


Standard-efficiency heating equipment should not produce condensation so if yours does, it could be that the flue pipe was not sized properly. The hot exhaust could be cooling and condensing within the pipe, then draining back into the furnace and leaking out. 

Clogged Drain 

Typically condensation from a high-efficiency furnace will flow out to a floor drain. If there is blockage in the line or the floor drain, it could cause a leak around your heating system. A heating tune-up from a furnace repair contractor should help avert this problem from happening. Unfortunately, skipping furnace maintenance may make you end up with a clogged drain, resulting in wood, ceiling, or other damage to your home. 


This malfunction should be caught with seasonal furnace tune-ups, but if your furnace is leaking water, the humidifier might be leaking inside the furnace. Water leaking into your heating system can cause serious damage to the internal components so it’s important to call your furnace service technician right away if you think this could be your issue. 

To make sure your heating system doesn’t spring a leak and that it’s ready to keep you warm all winter long, call Stevenson Service Experts in Columbus today. Our fall promotion is happening now and you can save on a fall tune-up or qualifying heating and air conditioning systems.
