HVAC Installation & Repair in London, ON
London, Ontario HVAC contractors in this directory cover Old North, Byron, Masonville, Hyde Park, Westmount, and surrounding London-Middlesex. Ontario's cold winters (-25°C design temps) and humid summers make hybrid heat-pump+gas-furnace systems the regional default. A 3-4 ton system with 80,000 BTU 96% AFUE gas backup for a typical 1,800-2,400 sq ft London home runs $13,500-$21,000 CAD installed.
London Hydro and Enbridge Gas cover most London utilities. Save on Energy and Enbridge Home Efficiency Rebate Plus offer significant heat-pump rebates. The 25C federal credit doesn't apply in Canada — Greener Homes Grant ($2,500-$5,600) does.
