Calgary’s climate is hard on furnaces. Long heating seasons, sudden chinooks, and dry air all combine to push your system to the limit. When your furnace runs almost nonstop for months, small issues can quickly turn into expensive repairs.
Skipping maintenance doesn’t just risk breakdowns, it can also mean higher gas bills, uneven heating, and even carbon monoxide dangers. Plus, when Calgary gets those deep freezes, frozen pipes and blocked vents become a real problem. Staying proactive is your best defense.

Pre-Winter Furnace Inspection Essentials
Before the first frost hits, give your furnace a good checkup. These simple maintenance steps can help prevent mid-season surprises.
Check and Replace the Air Filter
A clogged filter is one of the most common causes of furnace problems. It restricts airflow, reduces efficiency, and can cause overheating. Replace your filter every one to three months, especially during heavy use in Calgary winters.
Inspect the Thermostat for Accuracy
Make sure your thermostat is in “Heat” mode and responds properly to temperature changes. Replace batteries if needed, and consider upgrading to a smart thermostat for more consistent control and energy savings.
Examine Vents and Air Registers
Blocked vents can strain your furnace and cause uneven heating. Walk through your home and make sure nothing, like rugs or furniture, is covering them. If airflow seems weak, it might be time for a duct cleaning to help air move freely again.
Clear the Outdoor Intake and Exhaust Pipes
Snow, ice, or debris can easily block your outdoor furnace vents, causing your system to shut down. During Calgary’s snowy stretches, check these weekly to ensure proper ventilation and safe operation.
Mid-Winter Furnace Maintenance Checklist
Once winter settles in, a few regular habits can help keep your furnace running like a champ.
Monitor Furnace Flame and Pilot Light
Your furnace flame should be a steady blue color. If it’s yellow or flickering, that could mean incomplete combustion, a sign of a problem with your burners or gas supply.
Listen for Unusual Noises
Rattling, banging, or squealing noises often point to loose parts, worn belts, or motor issues. Catching these early can save you from bigger repair bills later.
Check System Airflow and Temperature
If some rooms feel colder than others or airflow seems weak, inspect filters and registers again. These symptoms could mean your blower motor needs attention.
Keep the Furnace Area Clear
Give your furnace room to breathe. Keep at least three feet of space clear around it, and never store flammable materials nearby.
Test the Carbon Monoxide Detector
This is one of the most important safety steps. Replace batteries every six months and make sure the alarm is working properly.
Professional Maintenance Tasks (Annual or Bi-Annual)
While some tasks are DIY-friendly, other deeper furnace maintenance tasks should always be left to certified technicians.
Deep Furnace Cleaning
Technicians clean the blower assembly, burners, and flame sensor to prevent buildup that can block airflow or cause ignition problems.
Lubricate Motors and Bearings
Lubrication keeps moving parts quiet and efficient, extending your furnace’s lifespan.
Inspect Heat Exchanger and Gas Lines
Heat exchanger cracks or gas leaks are serious safety risks. Professional inspections catch these early before they become hazards.
Test Ignition and Safety Controls
A technician ensures your furnace starts smoothly and shuts down safely every time.
Check Electrical Connections and Voltage
Loose wiring or low voltage can lead to short circuits or system inefficiency. Routine testing keeps everything running reliably.
Signs Your Furnace Needs Immediate Attention
- Cold air blowing instead of heat.
- Strange odors like burning or gas.
- Rising energy bills without explanation.
- Frequent cycling or uneven room temperatures.
