When the weather gets cold in Calgary, your furnace becomes the most important piece of equipment in your house. It keeps the temperature of your home comfortable and prevents winter-specific issues like frozen and burst pipes. However, since your furnace remains inactive during the summer and spring seasons, it may develop faults without you realizing it.

Here are a few signs that you need to get your furnace repaired before the winter sets in.

Loud Noises

A normal-functioning furnace is not exactly silent but does not make unnecessarily loud noises, either. However, if you hear loud noises from your furnace, it may indicate worn down components. A grinding sound may mean your motor needs lubricant, a metallic shriek means your motor bearings have worn down, a clicking sound may mean a fracture in the heat exchanger and a rattling sound may mean loose components in the blower fan.

Short-Cycling

If you have had your furnace for over a decade, you may have trouble switching it on and keeping it running. The problem may be due to a clogged filter, out-of-order thermostat, and disconnected wiring, which can cause your furnace to short cycle.

It could also mean some fault is causing your furnace to finish its heating cycle sooner, which not just puts a strain on the system, but also raises energy bills.

Unusual Smells

If you notice a strong smell of fuel that does not dissipate over time, your furnace may be suffering from any of several issues, including excessive dust, gas leaks, or blocked vents.

Discolored Flame

A normal pilot light appears blue. However, a yellow flame may indicate carbon monoxide leaks or ventilation problems. Some other signs of carbon monoxide are excess moisture on walls, windows and other cold surfaces, sooty streaks around the furnace, rust on flue pipes, water leaking from the vent or chimney, rust on the vent that can be seen from the outside.

Insufficient Heating

Some heating issues arise not from the furnace itself, but the leaking ductwork in your house. However, it could also be a problem with your furnace. If your furnace is not producing enough heat, no matter its thermostat reading, it may be because of worn down components.
