About this service
Heat Pumps and Air Conditioning in the Niagara Region
Heat pumps are the most efficient heating and cooling option for most Niagara homes — a single system providing both heating in winter and air conditioning in summer. Modern cold-climate heat pumps work effectively down to -25 degrees Celsius.
We install and service air source heat pumps, mini-split heat pumps, and central air conditioning systems across Niagara. Whether replacing aging equipment, adding cooling to a heating-only home, or converting to a heat pump for better efficiency — we size and install the right system.
Some heat pump installations qualify for federal or provincial efficiency rebates. These programs open, close, and change amounts regularly, so we check what is actually available at the time you are quoting rather than promising a number. We also handle AC repairs, refrigerant service, coil cleaning, and annual tune-ups for existing systems.

Common questions
Heat Pumps and Air Conditioning FAQs
Are heat pumps worth it in Niagara climate?
Yes — modern cold-climate heat pumps work to -25 Celsius and are 2-3x more efficient than electric baseboard. Many homeowners pair a heat pump with gas furnace backup for the coldest nights.
What rebates are available for heat pump installation in Ontario?
Canada Greener Homes offers up to $5,000 for qualifying installations. Ontario also has the Home Efficiency Rebate Plus program. Call 289-488-1007 to find out what you qualify for.
Can you add AC to a home that only has a furnace?
Yes — we add central air to most forced-air furnace systems. For homes without ductwork, a mini-split heat pump provides both heating and cooling without duct installation.
How often should AC be serviced?
Once a year before cooling season — typically April or May. Includes coil cleaning, refrigerant check, and electrical component testing.
