5 Early Signs of a Failing Furnace

Horizon Heating Logo

1) Your Furnace is Constantly Running

A furnace that runs all the time or frequently cycles on and off is not running efficiently. Make sure the air filter is not clogged or dirty. If the problem continues to persist, it may be time to call a professional for furnace maintenance.

2) There is an Unpleasant Odour

A dusty smell when you first turn on your furnace for the season is normal; however, if the smell continues or you notice a burning smell, shut off the system. Your furnace may be in need of furnace repairs.

3) Carbon Monoxide is Present

A carbon monoxide detector is a necessary safety item in any home with gas appliances. If your detector goes off, immediately turn off all gas appliances, open the doors and windows, and leave the house. Call a professional HVAC company to come test your furnace and other gas appliances to make sure they are functioning properly.

4) There is Excessive Noise

Loud banging, squealing, rattling, squeaking, grinding, or popping noises indicate that there may be a problem with your furnace. Regular furnace maintenance can prevent your furnace from experiencing these issues over time.

5) Sudden Increase in Utility Usage

It is normal to experience an increase in your utility bill during the colder months when you run the furnace. A sudden spike in utility costs is different and is likely due to a problem with the furnace.
