Mississauga HVAC service — furnace, AC, heat pump, boiler, water heater
HVAC install, repair and maintenance across Mississauga — from Long Branch and Mimico on the lakeshore, up through Islington and The Kingsway, to Rexdale and Humber Summit in the north. Same-day scheduling, 24/7 emergency response, licensed and insured for all gas work.
Mississauga's HVAC stock reflects its layered development — 1940s-1950s bungalows in Long Branch and Alderwood, mid-century in Islington and Kingsway South, 1970s subdivisions in Rexdale, and modern infill everywhere in between.
Older Mississauga homes often have mid-efficiency furnaces well past their expected life. For homes with 80% AFUE furnaces 15+ years old and aging central AC, cold-climate heat pump replacement paired with federal + local gas utility rebates often makes the financial math work — even before considering monthly operating savings.
The Kingsway and Baby Point areas have many century homes with hot water radiator heating (boilers). We handle combi boiler replacement, hydronic system service, and old-radiator troubleshooting. Radiator heat done right stays comfortable at lower thermostat settings.
For Mississauga high-rise and mid-rise condos along the Humber and Bloor West corridor, we service in-suite HVAC where building management approves external contractors.

Old 1958 hydronic boiler was on borrowed time. Replaced with a high-efficiency combi boiler, radiator zones balanced, comfort restored. Their century-home experience was obvious.

Kingsway — boiler replace

Went with a heat pump conversion. Rebate paperwork ($7,500 total) all handled. Whole-house energy costs down noticeably. Zero drama on install day.

AC failed on a 34°C day. Tech onsite in 90 minutes, capacitor replaced from truck stock, cooling within 3 hours of call. Life-saver during heatwave.

Islington — emergency AC
★★★★★
Annual furnace tune-up caught a cracked heat exchanger. Would have been a CO risk. Replaced under warranty extension, safer and more efficient than the failing unit.
