There’s nothing quite like waking up in a Calgary cold snap only to realize your furnace has stopped working. You can practically see your breath in the living room, and your dog is giving you that “fix this, human” look. Don’t panic because furnaces often stop for simple reasons that you can check safely before calling for emergency repair.
This guide will walk you through the first things to try, how to stay warm in the meantime, and when it’s time to call a local Calgary technician to bring the heat back.

First Steps to Take Immediately
Before assuming the worst, start with the basics. Many furnace problems in Calgary homes come down to small issues that can be resolved in a few minutes.
1. Check your thermostat settings and batteries.
Make sure your thermostat is set to Heat and the temperature is higher than the current room temperature. If it’s digital, swap out the batteries; dead ones are often the culprit.
2. Verify your furnace has power.
Check your home’s breaker panel for a tripped circuit. Also, look for a light switch near your furnace (it often looks like a normal wall switch) and ensure it’s turned on.
3. Inspect your furnace filter.
A clogged air filter can restrict airflow and cause your furnace to overheat and shut off automatically. If it’s gray or dusty, replace it.
4. Look for error codes or flashing lights.
Most modern furnaces have a small window with a flashing indicator. Count the flashes and check your user manual (or search your furnace brand online) to decode the issue.
Temporary Measures to Stay Warm Safely
If your furnace won’t turn back on, don’t freeze while waiting for repairs. There are safe ways to stay warm:
- Use space heaters on a flat surface and keep them at least 3 feet from anything flammable.
- Close off unused rooms to trap heat in the areas you’re using.
- Layer up with warm clothing and thick blankets.
- Open your blinds during the day to let in sunlight, then close them at night to retain heat.
- Avoid using your oven or stove for heat, this is unsafe and can lead to carbon monoxide buildup.
When to Call a Calgary Furnace Technician
If your furnace still won’t start after all these checks, it’s time to call in a professional. You should contact Comfort Union’s furnace repair team in Calgary immediately if your furnace keeps cycling without producing heat, makes loud banging, clicking, or buzzing noises, or if you notice a gas or burning smell. Another red flag is a flickering or yellow pilot light instead of a steady blue one, which can signal a combustion issue. A licensed technician can perform a full diagnostic, pinpoint whether the problem lies with ignition, sensors, or controls, and fix it safely. They’ll also test your furnace for efficiency to make sure it’s heating your home properly without wasting energy.
How to Prevent Future Furnace Failures
Calgary winters are harsh, but most furnace breakdowns can be avoided with a bit of preventive care. Schedule a furnace tune-up and maintenance service every fall before the cold hits to ensure your system is ready for the season. Replace filters every one to three months, depending on usage and home conditions, to maintain proper airflow. Keep vents and exterior exhausts clear of snow and debris, and have your ducts inspected for leaks or blockages that could reduce efficiency. It’s also important to make sure your thermostat is accurate and not influenced by direct sunlight or drafts. Proactive maintenance costs far less than emergency repairs and provides peace of mind all winter long.
