What Could be the Reasons for a Furnace to Stop Working?

Canadian winters are something you shouldn’t take lightly. Especially in regions like Ontario, you can often see snow during winter. You check if everything’s perfect to be comfortable in this chilling weather, from thick socks to fuzzy scarves. However, you still feel chilly inside your house because your furnace has stopped working! There can be many reasons behind the furnace preventing it to work.

While in most cases you need to call a professional furnace repair in Cambridge, Ontario, here are a few things you can check before making a call.

4 things that might cause a furnace to stop

Thermostat issues

A wrongly set or malfunctioning thermostat is one of the most common causes of furnaces not working properly. Always check and set your thermostat to heat instead of cool, then set the temperature to 5 degrees above room temperature. After this simple fix, the furnace must work. However, if that’s not the case, you should consider changing the batteries of the thermostat. 

If your thermostat has gone blank, it is highly indicative that the battery has died and it can no longer operate your system. Thus, remember to replace the thermostat’s battery every year.

Dirty or clogged furnace filter

Are you noticing that your furnace isn’t blowing as much heat as it used to? One of the main culprits behind this is the dirty air filters. Over time, dirt, debris, and gunk accumulate in the filters, restricting the airflow or sometimes completely blocking it. Not only does it affect the airflow, but it also overheats the heat exchanger. 

Therefore, it’s always recommended to get your filters changed every three months by a professional heater repair in Rockwood. 

Examine air ducts

There is enough hot air coming out of the vents, but still, you can find cold spots in your home! If you are currently facing this issue, it’s time to check your ductwork. Inspect the dampers, which are present as handles protruding from the ducts. Make sure they are fully open as they control the overall airflow.

However, if an entire room is still cold, there might be a leaking duct. In worse cases, the problem can be incorrectly designed ducts. This is a serious problem that can only be fixed by a professional furnace repair in Cambridge, Ontario. If you don’t address this on time, it can cause strain to the system and also spike your energy bills. 

Power issues

Firstly you must check if the furnace and thermostat are even turned on or not. Yes, most of the time, people forget to switch them back on after checking them. You should also check on the circuit breaker and fuse box of the furnace. At last, ensure that the front panel of the blower is sealed correctly. You should fully press the push-in switch located under this cover for the furnace to turn on.
