With winter weather arriving quickly and the holidays approaching, the last thing you want to happen is your furnace breaking down in the middle of one of the busiest seasons! Keep reading to learn about the signs you can look for that signify you need your furnace repaired.

Burner Flame Color

If your burner flame is yellow, it means the furnace is dirty and not being ventilated as it should be. This can lead to carbon monoxide not being ventilated and becoming a danger to anyone in your home. If you don’t already have one, set up a carbon monoxide detector in your home to ensure the safety of you and everyone else that lives there.


When air isn’t circulating in your home correctly, it’s not uncommon to see moisture buildup in certain rooms or areas of the house. Excessive moisture and damp air can mean there’s a problem with your vents or furnace. If you are having problems with the ventilation, consider calling a professional to take a look and diagnose the problem.

High Utility Bills

There are multiple reasons you might notice a sudden increase in your utility bills; however, there’s a good chance that it’s being caused by your furnace not working properly. Check your furnace to see if it needs cleaning. A dirty filter can obstruct the airflow. If this is the case, it just needs to be cleaned, and you should be able to see a difference in the next month’s bill.

Water Leaks

A multitude of different things can cause a water leak. If you notice water leaking when the air conditioner is running, that’s likely a sign that it has something to do with the HVAC unit, which is a simple fix. If water leaks from the furnace itself, it may be time to call a professional to look into things, as it might be something more serious.

Cold Air

If you’ve turned on your furnace but are not feeling any warm air, chances are something isn’t working quite right. If your furnace is blowing cold air, you likely have a malfunctioning motor on your hands. The best thing to do in this situation is to call a professional to take a look and diagnose the problem.

At the end of the day, if you are noticing problems with your furnace, the simplest thing you can do is a professional to look at what’s going on and make sure everything is working correctly.
