HVAC in Markham

Heating & Cooling Built for Markham Homes

Markham mixes old and new like few GTA cities. Unionville and Markham Village have heritage and older homes where the mechanical room is tight and the ductwork was never designed for central air. Newer communities like Cornell, Berczy Village, Wismer, Greensborough and Cathedraltown are full of townhomes and two-storey homes built in the 2000s and 2010s — many with three floors to keep comfortable.

Three-storey townhomes are a classic Markham problem: the top floor bakes in summer while the basement stays cold. We fix that with properly sized equipment, balanced airflow, a smart thermostat and — where it's needed — a ductless head for the top floor.

FAQ

Common Questions

Do you install HVAC across all of Markham?
Yes — Unionville, Markham Village, Cornell, Berczy Village, Cathedraltown, Milliken and everywhere in between.
My top floor is always too hot — can you fix it?
Usually, yes. Hot top floors in Markham townhomes come from undersized or unbalanced systems. We check sizing and airflow, and a ductless head on the top floor is often the most effective fix.
What rebates can Markham homeowners get?
Through Ontario's Home Renovation Savings Program, cold-climate air-source heat pumps qualify for up to $2,000 in homes heated with natural gas and up to $7,500 in homes heated with electricity, oil or propane — pre-approval is required before installation. A new federal heat pump rebate is expected in 2027. Furnaces and central AC don't currently qualify for government rebates. See our 2026 rebate guide for details.
Are you licensed and insured?
Yes. Temple Construction Corp is TSSA approved and carries $5M liability insurance, serving the GTA and Ontario since 2014.
