Your furnace moves through cycles to maintain the consistent temperature you set through your thermostat. However, you should notice your furnace kicking on and off more than a few times in an hour, or your furnace running without meeting your thermostat’s set temperature, it could indicate a problem

Your furnace has one very important job: to warm up your home and keep you comfortable when the temperature drops. One of the most common reasons for emergency calls to our team is that air that’s blowing, but not warm.

When your thermostat is in good working order but your home temperature is still dropping, there is a chance your furnace isn’t turning on at all. 

Your furnace’s sound should be almost non-existent, except for the subtle hum of air rushing through the ducts. Sounds along the lines of grinding, clinking, whirring, squealing, or shaking is cause for concern.

Your bills would naturally rise during the winter months, but if you notice that they are higher than last year’s or higher than what your neighbours are paying, there might be a problem. Furnace units in the process of failing will operate inefficiently, resulting in a significant increase in your monthly energy bill. Then it is time to call the Proto Plumbing & Heating for professional Furnace Repair Service.
