4 Common Furnace Problems & Their Solutions

Canada has some of the harshest winter conditions in the world so people here have to gear up accordingly to avoid getting sick. The temperatures can drop as low as -30 degrees Celsius, especially in Calgary and surrounding areas. Thus, heating systems like heaters and furnaces are a necessity to keep their homes warm throughout the winter months.

If you have not turned on your heating system for a few months, there is a chance its maintenance is due. There’s nothing worse than waking up in the middle of the night and finding out that the cold air in your room has nothing to do with your blanket falling off rather your heating system is not working properly. At this point, it is advised that you contact a residential plumbing company.

However, the best practice is to schedule a furnace maintenance check before winter arrives to avoid frustrating situations. Read our post to find out what furnace issues are most common and how to solve them.

Furnace Won’t Turn On

There are many reasons why your furnace may not turn on. These include:

Improper Thermostat Settings

For this, you must ensure that the thermostat is switched on and set to ‘heat’.

Tripped Circuit Breaker

Check if the furnace’s circuit is on or not. If the switch has tripped, turn it on to get it working again.

Activated Safety Switch

The furnace door has a safety switch that prevents the system from running if the door is open or removed. Check to see if the door is still in place and the switch hasn’t tripped.

If the problem is still unresolved then it might be time for you to purchase a brand new thermostat.

Cool Or Insufficient Airflow

If cool or slightly warm air is coming out of your vents, it means that your furnace isn’t transmitting or producing the appropriate amount of heat. You should check your air filter first to see if it is clogged. Dust and dirt can accumulate inside your air filters over time and block them.

A clogged filter will make your furnace work harder to provide enough airflow to adequately warm your home. You need to schedule a maintenance check with your local Calgary plumbers to have your air filters cleaned – at least once a month.

Moreover, if the area around your heating furnace is cluttered then you may have insufficient airflow. It will be difficult for your furnace to pull in enough air to warm your home. It is advised that you clear the area to give the HVAC system plenty of room to breathe.

It is Making Strange Noises

If you hear a squealing or squeaking sound coming from your heating system, this typically means a problem with the blower or belts. You must oil your blower at least once a year to ensure its smooth, quiet operation. This is called a routine system tune-up. In addition to this, worn-out furnace belts can also produce a squealing sound.

To avoid these problems, you must schedule an annual maintenance inspection for your plumbing system. A banging sound coming from the heating system is usually associated with the blower. It indicates that your blower is either damaged or imbalanced.

If you hear such noises from your furnace, immediately turn it off and call a professional plumbing expert to diagnose and repair the problem as soon as possible. They will also be able to tell if the issue can be fixed by a simple repair or if a replacement is needed.
