How Often Should You Service Your Furnace in Calgary?

Why Annual Furnace Servicing Matters in Calgary

Calgary's winters are long and cold. From late September through April, your furnace runs almost continuously. That is six or more months of near-constant operation — and like any mechanical system that works hard, it needs regular maintenance to perform reliably and safely.

Annual furnace servicing is not just about preventing breakdowns. It is about safety, efficiency, and protecting your investment.

How Often Should You Service Your Furnace?

The industry standard recommendation is once per year. For Calgary homeowners, the ideal time is September or early October — before the heating season begins in earnest. Booking early also means you avoid the rush: HVAC companies get extremely busy in November and December when furnaces start failing during the first cold snaps.

If your furnace is older than 12 years or has a history of problems, consider servicing it twice per year — once in fall before heating season and once in spring after.

What Happens During a Professional Furnace Tune-Up?

A professional furnace service from Infills Mechanical includes a thorough inspection and cleaning that covers every major component.

Our technicians will clean the heat exchanger and burners to remove carbon buildup that reduces efficiency and can cause combustion problems. We test gas pressure and combustion to ensure your furnace is burning fuel completely and safely. All moving parts including the blower motor and inducer are lubricated to reduce wear. Electrical connections are checked and tightened, as loose connections are a common cause of intermittent failures.

We also measure static pressure in your ductwork, which reveals airflow problems that reduce heating efficiency. Safety controls including the high limit switch and pressure switches are tested. The evaporator coil is inspected if you have central air conditioning. We check refrigerant lines for the same system. Finally, we inspect your ductwork for leaks and provide a written report of our findings.

The Cost of Skipping Annual Maintenance

Furnaces that are not regularly serviced are up to three times more likely to break down during peak winter months. Emergency service calls in Calgary during cold weather cost significantly more than a planned maintenance visit — and if parts need to be ordered, you could be without heat for days.

Beyond breakdowns, a poorly maintained furnace runs less efficiently. Dirty burners, a clogged heat exchanger, or restricted airflow can increase your gas consumption by 10 to 20 percent. Over a full heating season, that adds up to hundreds of dollars in wasted energy.

DIY Maintenance Between Service Visits

There are several things you can do yourself between professional tune-ups to keep your furnace running well.

Replace your furnace filter every one to three months depending on filter type and home conditions. A clogged filter is the single most common cause of furnace problems and is entirely preventable. Check your thermostat batteries annually. Test your carbon monoxide detectors and smoke detectors at the start of each heating season. Keep the area around your furnace clear of storage and flammable materials. Listen for unusual sounds — banging, rattling, or squealing often indicate developing problems that are cheaper to fix early.

Signs Your Furnace Needs Service Now

Do not wait for your annual appointment if you notice a yellow or orange flame instead of blue, a gas smell near the furnace, short cycling where the furnace turns on and off rapidly, unusual noises during operation, or a carbon monoxide detector alarm.
