What Makes Labour More Expensive
Multi-story access
+$500-$1,500
Routing ducts between floors takes significantly longer. Two-story homes with second-floor HVAC access cost more.
Attic installation
+$300-$800
Working in a hot, cramped attic takes more time and is harder on installers. Air handler in attic adds labour time.
Crawl space installation
+$400-$1,200
Confined space access, especially for return air ductwork, adds significant labour hours.
Tight/difficult access
+$200-$600
Old homes with narrow access panels, finished walls over ducts, or limited utility area add time.
Electrical panel upgrade
+$800-$2,000
If your panel cannot handle the new system, a panel upgrade is often required. Separate electrician work.
Old system removal complexity
+$200-$500
Old equipment in cramped spaces, or R-22 systems requiring careful refrigerant recovery, take longer to remove.
Emergency/same-day service
+30-50%
Emergency summer calls during heat waves command premium pricing. Plan ahead to avoid this.
Permit coordination
+$150-$400
Some contractors charge for permit filing, inspection scheduling, and the time spent on compliance paperwork.
