Edmonton HVAC Commercial Checklist
Commercial HVAC systems in Edmonton face unique demands - from -40°C winter shutdowns to full summer cooling loads, plus strict Alberta building code compliance requirements. Unplanned equipment failures in a commercial building can mean tenant complaints, lost productivity, regulatory issues, and costly emergency repairs. This checklist helps property managers and facilities teams stay ahead of maintenance, document service history, and know when to call a certified commercial HVAC technician.

Rooftop HVAC Units (RTUs)
- Inspect RTU cabinet for physical damage, rust, or panel corrosion
Edmonton's freeze-thaw cycles accelerate cabinet corrosion — check seals annually - Check and replace RTU air filters — minimum quarterly for commercial use
High-occupancy buildings may require monthly filter changes for ASHRAE compliance - Inspect heat exchanger for cracks or carbon deposits
A cracked heat exchanger is a CO safety hazard — must be inspected by a licensed tech - Test economizer damper operation — should open/close smoothly
Failed economizers waste significant energy and are a common code violation - Inspect refrigerant lines and connections for leaks or oiling
Refrigerant leaks must be repaired by a certified refrigeration mechanic - Check condenser and evaporator coils — clean if fouled
Fouled coils reduce efficiency by 20–40% and increase equipment wear - Inspect fan belts, bearings, and motor mounts for wear
Belt failure on a rooftop unit during an Edmonton winter can cause rapid building temperature loss - Test unit controls, safeties, and BAS integration points
Ensure thermostat, building automation, and lockout safeties are communicating correctly - Clear rooftop drains and check unit curb for water pooling
Standing water around RTU curbs causes structural damage and unit corrosion - Verify unit is properly anchored and vibration isolation intact
Wind loads in Edmonton require that RTU anchoring meets Alberta Building Code - Document unit model, serial number, and last service date
Maintenance records are required for equipment warranty claims and building inspections
Commercial Air Conditioning & Cooling
- Test cooling operation across all zones before summer season
Book spring startup in April — Edmonton's cooling season arrives quickly - Inspect and clean condenser coils at start of every cooling season
Clean coils lower operating pressures and reduce compressor wear - Check refrigerant charge — superheat and subcooling readings
Improper refrigerant charge is the leading cause of compressor failure in commercial systems - Inspect and clean condensate drain pans and drain lines
Blocked condensate in a commercial system can cause water damage to ceilings and tenant spaces - Verify zone controls and programmable thermostats are calibrated
Miscalibrated zone controls lead to comfort complaints and energy waste - Inspect VRF/VRV branch selectors and refrigerant piping insulation
Damaged insulation on VRF systems causes condensation and energy loss - Check ductless split systems — clean filters and inspect linesets
Indoor ductless units in commercial spaces require quarterly filter cleaning minimum - Test compressor amp draws against nameplate ratings
High amp draw is an early warning sign of compressor wear or refrigerant issues - Inspect all electrical connections, contactors, and capacitors
Loose connections and failed capacitors are the most common cause of mid-season breakdowns
Ventilation, Exhaust & Air Quality Systems
- Inspect and clean HRV/ERV cores — minimum twice annually
Dirty HRV cores reduce ventilation efficiency and can cause condensation problems - Test make-up air unit (MAU) operation — check burner, filters, and dampers
MAUs are critical for buildings with high exhaust loads — restaurants, labs, warehouses - Inspect all exhaust fans — check belts, bearings, and damper operation
Failed exhaust dampers allow cold air infiltration in Edmonton winters, causing freeze damage - Verify kitchen exhaust hood static pressure and grease filter condition
Grease buildup in commercial kitchen hoods is a significant fire hazard - Test CO and CO2 sensors in parking garages and mechanical rooms
Alberta Fire Code requires functional CO detection in enclosed parking facilities - Check outdoor air damper actuators for proper modulation
Stuck-open outdoor air dampers in winter are a major heat loss source in commercial buildings - Inspect ductwork for leaks, disconnects, or damaged insulation
Duct leakage in commercial buildings commonly wastes 20–30% of conditioned air - Verify building pressurization — positive pressure relative to outside
Negative building pressure pulls in cold air and contaminants through every gap in the envelope - Test smoke and fire dampers for proper operation
Annual smoke/fire damper testing is required under Alberta Building Code - Review ventilation rates against ASHRAE 62.1 minimum requirements
Occupancy changes (new tenants, renovations) often require ventilation system rebalancing
Commercial Heating Systems
- Service commercial boiler annually — clean, tune, and safety test
Alberta requires annual boiler inspections for vessels over certain pressure ratings - Test all boiler safety controls — high limit, low water cutoff, pressure relief
Safety control failures are the leading cause of boiler-related insurance claims - Inspect hydronic heating system for air locks, corrosion inhibitor levels
Neglected hydronic systems develop internal corrosion that destroys pumps and heat exchangers - Check unit heater operation in warehouse and garage spaces before winter
Unit heater failures in Edmonton warehouses can damage inventory and create unsafe conditions - Inspect gas-fired infrared heaters — burner, reflectors, and ignition
Dirty reflectors reduce radiant heating efficiency significantly in large open spaces - Test building heating controls and zone valves for proper operation
Stuck zone valves cause cold spots, comfort complaints, and energy waste - Check expansion tank pre-charge pressure in hydronic systems
A waterlogged expansion tank causes pressure fluctuations and premature pump failure - Inspect all gas connections and test for leaks with approved detector
Commercial gas leak inspections should be performed by a licensed gas fitter - Verify combustion air supply to all fuel-burning equipment
Inadequate combustion air causes incomplete combustion, CO production, and equipment damage - Check heat tracing on exposed pipes and roof drains
Heat trace failures in Edmonton cause frozen pipes, burst lines, and costly water damage
Commercial Plumbing & Water Systems
- Annual backflow preventer testing — required by City of Edmonton bylaws
Backflow device testing is mandatory annually — Hydro-Flo is a certified tester - Inspect and service commercial water heaters or booster heaters
Commercial water heater failures affect tenant satisfaction and can create liability - Pump and inspect grease interceptors — frequency per municipal requirements
City of Edmonton requires grease trap maintenance records — failure to comply risks fines - Inspect water softener and filtration systems — check media and salt levels
Edmonton's hard water (170–200 mg/L) damages commercial equipment without treatment - Test domestic hot water recirculation system for Legionella risk management
Buildings over a certain size require documented Legionella water management programs - Inspect all exposed plumbing in mechanical rooms for corrosion or leaks
Undetected slow leaks in mechanical rooms cause structural damage and mold growth - Check sump pumps in all below-grade areas before spring thaw
Spring groundwater infiltration in Edmonton is a significant risk for below-grade spaces - Inspect roof drains and overflow drains — clear debris before freeze-up
Blocked roof drains cause ponding and structural overload risk — especially with Edmonton snowfall - Review cross-connection control program with building records
City of Edmonton's Cross Connection Control Bylaw requires annual inspection programs for many facilities
Restaurant & Food Service HVAC
- Kitchen exhaust hood cleaning — per NFPA 96 frequency requirements
Monthly for high-volume frying; quarterly for moderate use; semi-annually for low use - Inspect and test make-up air unit matched to kitchen exhaust volume
Improperly balanced kitchen MUA causes negative pressure, back-drafting, and comfort issues in
dining areas - Service walk-in cooler and freezer refrigeration systems semi-annually
Refrigerant leaks in walk-in units cause food spoilage, health code violations, and insurance issues - Check walk-in cooler door gaskets and heater strips
Failed door heaters cause frost buildup and compressor short-cycling in Edmonton's climate - Inspect dish machine ventilation and condensate management
Dish machines produce massive amounts of steam — proper ventilation prevents ceiling and structural damage - Test cooking equipment gas connections and verify BTU ratings
Annual gas pressure and leak testing for all cooking equipment is best practice and often required by
insurers - Inspect dining room HVAC for odor transfer from kitchen
Kitchen-to-dining odor transfer indicates insufficient negative pressure at kitchen exhaust — requires
balancing - Check patio heating equipment before season — infrared or forced air
Patio heaters must be inspected and certified before each use season per Alberta Safety Codes
