HVAC Services in Mississauga

Trusted HVAC Experts in Mississauga

Mississauga's trusted HVAC contractor since 1999. From Port Credit to Meadowvale, Streetsville to Erin Mills — Megacity HVAC delivers professional heating and cooling services to homes across Mississauga. Our TSSA-certified technicians handle everything from furnace installations and AC repairs to heat pump systems and indoor air quality upgrades. Mississauga offers one of the widest housing ranges in the GTA, from heritage properties in Streetsville Village and lakefront homes in Port Credit to modern condo towers in City Centre and expansive newer builds in Churchill Meadows. Each neighbourhood brings distinct HVAC challenges, and our team has the expertise to match the right system to your home's specific layout, age, and insulation profile.

Mississauga's housing spans multiple eras — Port Credit and Lakeview feature charming 1930s–50s bungalows and cottages with limited ductwork space, while Erin Mills and Meadowvale have 1980s–90s suburban homes with standard forced-air systems now reaching end of life. Streetsville's heritage district has older homes that sometimes require creative HVAC solutions to preserve character while adding modern comfort. The City Centre condo corridor presents unique challenges with fan coil units, and newer Churchill Meadows developments often have builder-grade systems that homeowners want to upgrade for better efficiency and comfort.

Mississauga's southern lakefront neighbourhoods in Port Credit and Lakeview enjoy milder winters but face high summer humidity from Lake Ontario, making properly sized air conditioning and dehumidification critical for comfort. Inland areas like Meadowvale and Churchill Meadows experience wider temperature swings and are more susceptible to the deep-freeze events that stress heating systems in January and February.
