10 Warning Signs That Your Edmonton Furnace Needs Immediate Attention

As one of the best furnace companies in Edmonton, Alberta, the team at Edmonton Furnace and Carpet Care has been leading the way in preventative maintenance and furnace repairs across the city of champions. We love working with our clients to extend the life of their units and provide meaningful maintenance that will keep repair costs down. With that in mind, here are 10 warning signs to look out for that would require a call to our team to help avoid major issues with your furnace.


1. Unusual or loud noises

Furnaces are not meant to be a loud machine in your basement. Instead, when operating, you should really only hear air moving around your ducts. If you are noticing banging, rattling or squealing from your unit, a call to an Edmonton furnace repair company is needed.


2. Frequent cycling

Modern furnaces are designed to operate efficiently and minimize cycling as much as possible. Cycling is not efficient; instead, your furnace should run for a period of time and then shut down until it is needed again. If you notice constant cycling, it might indicate a repair is needed.


3. Unequal heating within your home

If you start to notice that one part of your house is getting a lot more heat than others, then you might have an issue with your furnace. Generally, a forest air system will evenly heat a home. If you are noticing massive temperature swings from room to room without any known cause, you should call an Edmonton furnace repair technician.


4. Strange odours coming from the furnace itself

Furnaces are supposed to run odourless during operation. If you notice a burning or musty smell, there may be an issue with the burner or air handler, which could require a professional furnace technician to inspect before a total system failure or worse, a fire occurs.


5. Sudden spike in your gas or electric bill

Generally, the cost to run your furnace should remain roughly the same throughout all months of operation. If we are in a cold snap, it could be running a little more than usual, but if you notice a significant spike in your Direct Energy, EPCOR, AltaGas, Just Energy, Link Energy or Burst Energy bill is a little higher than normal, it is worth the call to us to check if there is no issues with your furnace or associated gas line in and outside of the home.


6. Visible signs of wear and tear around your furnace

We always recommend that clients perform a routine visual inspection of their furnace. If you notice signs of rust, corrosion, or soot around your furnace, there may be an issue. It could be as simple as a small leak within the unit, but having this checked out before significant damage occurs can extend the life of your unit.


7. Thermostat not responding to changes

The heart of any home heating system is the thermostat, and if it is not functioning as designed, you should call a registered furnace technician as soon as possible. There are dozens of reasons why it could be failing to call down to the furnace, and our technicians can get to the bottom of it and get the hot air moving once again.


8. The furnace is struggling to start

We have seen so many older furnaces struggle to start that require just a quick fix from one of our technicians. It could be something like a pilot light issue or even that an igniter has moved within the unit. Whatever the issue, if your furnace is struggling to start, we can help resolve it once and for all.


9. Carbon monoxide alarms are going off

If you have gas appliances, your carbon monoxide detector could be a lifesaver. If it goes off, please call us as soon as possible. As trained gas technicians, our team can identify the issue and stop the gas leak before it becomes dangerous within your home.


10. Cold air is blowing instead of hot air

A telltale sign that you need to chat with a furnace technician is when your furnace starts blowing cold air during operation. This means that there is an issue with the burner, and a quick fix from a registered furnace contractor can help get that hot air moving through the system once again.
