6 Furnace Fail Warning Signs

When it comes to HVAC systems, the changing weather of autumn can bring some unexpected problems. At the first sign of chilly fall winds, homeowners find themselves turning on furnaces that haven’t been used for several months. Have you ever turned on your furnace to discover that it’s not heating your home the way you expected? There are a few potential reasons why your furnace could be failing you:

Older Unit

Your furnace could simply be running on its last legs. Have you moved into an older home recently, or simply haven’t replaced your furnace in a while? It may be time to do so. Furnaces usually only last between 15-20 years, so if you are not feeling the warmth, your furnace may be telling you it’s time for an upgrade. You can check information about its age on the serial label posted on your furnace.

Cold Air Flow

Cold air flowing through your furnace could be another warning signthat your system is due for a revamp. If you find cold spots in your home, it’s time to contact a professional, as your blower fan may be malfunctioning!

Yellow Pilot Light

Behind the front panel of your furnace, you can find your pilot light. Check the colour; is it yellow? If so, this could be a sign that your heat exchange is leaking carbon monoxide, which poses a huge risk for you and your family. Seek professional service immediately, if there’s any potential for a carbon monoxide leak. Just remember, BLUE means GO, YELLOW means Oh NO!

Unusual Noises

Although furnaces do tend to generate sounds when running, pay attention to any sound that’s out of the ordinary for your furnace. In particular loud and high pitched pops and squeaks could indicate that there is something loose in your unit.

Dust

Finding an unusual amount of dust buildup in your furnace could mean that your furnace is not able to clean your air properly. If you are experiencing this issue, call one of our technicians for assistance – your family will be happy you did!
