5 Things to Check

These are some of the easy checks you can do before calling for furnace repair. If these things check out and you are still having problems, please give LSM a call at 780-532-4418 or after hours at 780-532-5210.

Furnace power switch – Was it turned off by mistake? In most homes, it looks like a light switch in the mechanical room, often above your light switch (closer to the ceiling).

Thermostat batteries - some thermostats take batteries. If the screen is blank, the batteries may be dead.

Thermostat – is the “System” section on your thermostat set to “Heat”? It may have been accidently changed to off, or cool, etc.

Furnace filter – has it been changed recently? Most filters will have instructions on how often your filter should be changed. The filter life varies from filter type, manufacturer and whether you run your furnace fan continuously.  Inexpensive, fibre-glass filters need to be changed every month.

Furnace exhaust/chimney or air intakes – check outside where your air intake or exhaust (high efficient are usually on the outside wall, but can be on the roof as well). If they’re on the roof or if you don’t have a high efficient, check that the snow cover is not obstructing the exhaust/chimney or air intake. If they’re on the side of the house, check that there is nothing stored too close: bushes, lawn chairs, snow build-up, something covering them (screen or fabric), etc. If you there is, you may see a lot of frosting around them. Remove the obstruction.

We have the nicest customers. This gift was dropped off yesterday to say thank you to David for going above and beyond on a service call. He shared with the rest of us in LSM Residential. Thank you Debbe, the cake was delicious.

Utility Outages

Air conditioning installation

If the utility company has announced a natural gas outage in your area, and you have an older furnace or hot water tank, you may need to relight your pilot light once the gas service is restored. Often the utility company will go door to door and offer to relight them for you. The outage can cause an air lock in the gas line when your furnace is trying to light during the outage, which can make relighting a bit tricky. Newer furnaces use hot surface ignitors rather than pilot lights. For these furnaces, our techs recommend that you turn the power switch to your furnace off during the outage. When you know the service has been restored, turn the switch back on and that should help minimize the lock-out.

Electrical outages can cause power surges when the lines power up which can damage circuitry in newer furnaces. To help prevent these issues, turn the furnace power switch off during the outage. Once the power has been restored and stabilized, turn the switch back on. An electrician can install a full home surge protector for you which can protect your furnace and other electrical appliances.

If you need help after an outage, give us a call 780-532-4418 (M-F 8:00 am to 5:00 pm), or after hours, weekends and holidays call 780-532-5210.
