Here’s how to prepare your commercial HVAC system to handle Calgary’s winter months with confidence.
1) Schedule a Professional HVAC Inspection
Before winter hits, book a comprehensive heating inspection with a certified HVAC technician. A fall inspection identifies worn components, airflow issues, or small problems before they become costly emergencies.
A professional tune-up typically includes:
- Inspecting burners, heat exchangers, and electrical connections
- Checking for gas leaks or carbon monoxide risks
- Cleaning and calibrating thermostats
- Testing efficiency and safety controls
Pro tip: Schedule your inspection early in the fall to avoid peak-season delays.
2) Replace or Clean Air Filters
Dirty or clogged filters restrict airflow, forcing your system to work harder and use more energy. Replacing filters every 1–3 months during heating season is one of the easiest and most cost-effective ways to improve efficiency and air quality.
3) Check Thermostat Settings and Zoning
Make sure thermostats are properly calibrated and programmed for winter hours. For larger buildings, verify that zoned areas are balanced to maintain consistent temperatures.
If your business uses smart or programmable thermostats, set lower temperatures during off-hours to save energy without sacrificing comfort.
4) Inspect Ductwork and Air Vents
Leaky or obstructed ducts cause uneven heating and wasted energy. Before winter:
- Inspect ductwork for visible damage or loose connections
- Clean vents and ensure they’re not blocked by furniture or equipment
- Consider professional air balancing for optimized airflow
Well-maintained ducts help heat distribute evenly and reduce strain during cold snaps.
5) Seal Drafts and Improve Insulation
Your HVAC system performs best when your building is sealed tight. Check for drafts around doors, windows, and exterior vents, and ensure your insulation meets Alberta’s recommended R-values.
Even minor leaks can let warm air escape—forcing your system to work harder and driving up costs.
6) Test Safety and Backup Systems
Cold weather pushes systems to the limit. Test your:
- Emergency shutoffs and safety controls
- Carbon monoxide detectors
- Backup heat sources
If your building uses boilers or rooftop units, verify that freeze protection systems and pipe insulation are intact to prevent freezing damage.
7) Set Up a Winter Maintenance Plan
Preventative maintenance helps you avoid mid-season emergencies. Partner with a trusted HVAC service provider to create a winter maintenance schedule including:
- Filter changes
- System performance checks
- Efficiency testing
- 24/7 emergency service options
Routine maintenance ensures safe, efficient heating all season long.
