Why Is My Furnace Leaking?

Posted on: November 8, 2016

Furnace systems are a great, effective way to get good quality heating here in Raleigh. But for all of their attributes, you don’t normally find them associated with moisture at all. Quite the opposite, in fact, as many North Carolina homeowners depend on humidifiers and other systems to counteract the dehumidification a furnace naturally provides. Because of this, it can be downright confounding when you start noticing a leak or standing water on or around your furnace.

So, what’s the deal? How is your furnace leaking water, and what can you do about it? Never fear, the certified HVAC team at Air Experts Heating & Cooling are here to help! We know furnace systems backward and forward, and through our years of experience, we can provide the answers you’re looking for.

Common Causes for a Furnace Leak

The good news is that your leaky furnace is a bit of an oddity. It’s a fairly uncommon issue, and thus has a small number of causes. Because of this, it’s pretty quick and easy for HVAC professionals like Air Experts to come in and provide the repair services you need.

If your furnace springs a leak, there could be a few causes at hand.

  • Your humidifier is faulty. If like many Raleigh homeowners, you make use of a humidifier in conjunction with your furnace, the odds are strong that the humidifier is your culprit. This tends to be the most common cause, unless you’re using a high-efficiency furnace, which we’ll get to later.
  • Your AC is still running. If your heating system and air conditioner are connected, there’s a real possibility that the condensate drain system of your AC is clogged, and thus pushing water into your furnace.
  • Your furnace isn’t leaking at all. Before you call in the team at Air Experts for furnace repair, be sure you don’t need to be calling a plumber instead! It is entirely possible that pipes in your home are the real cause of your leak. Check carefully around the area with standing water and look for any signs of water damage or leaking, like dark spots on walls and floors, discoloration, or mold.

Do You Have a High-Efficiency Furnace?

If so, we’ve got some good news and some bad news. The good news is we almost definitely can tell you your problem right off the bat! The bad news is that it will absolutely require professional furnace repair. But don’t stress too much; our experts are very adept at servicing high-efficiency furnace problems.

If you’re using a high-efficiency furnace, then your leak is actually the most common reason for a furnace leak. High efficiency systems use a secondary heat exchanger to gain that great efficiency. The trouble is, the double exchanger allows a moment for air to rapidly cool, so if your furnace is in poor condition, this step can lead to the development of condensation. And that’s where your moisture is coming from! Don’t worry, our team can repair the issue for you to get your high efficiency furnace running as good as new.
