Furnace Installation in Newmarket

Furnace replacement is our most requested service in Newmarket. Most Newmarket homes need 60,000–100,000 BTU Lennox furnaces sized by Manual J calculation. We carry Lennox Merit ML196E (96% AFUE), Elite EL297V (97% AFUE, variable-speed), and Signature SLP99V (up to 99% AFUE, modulating). All installations include a TSSA permit, standard venting, and removal of your old furnace. See our full Lennox furnace installation page or our furnace replacement cost guide.

For urgent furnace failures in Newmarket, call (905) 951-8080 directly — same-day service available during heating season. See our furnace repair service for emergency details.

Heat Pump Installation in Newmarket

Newmarket homes on Enbridge natural gas are ideal candidates for a dual-fuel hybrid system — a Lennox cold-climate heat pump (SL25XPV, EL22XPV) paired with a gas furnace backup. The heat pump handles 70–80% of annual heating hours efficiently; the furnace covers the coldest Newmarket days. Ontario Home Renovation Savings (HRS) rebates may apply — see our Ontario heat pump rebates guide.

Is There a Furnace Rebate in Newmarket?

No. There is currently no Ontario or federal rebate for gas furnace replacement. The Canada Greener Homes Grant closed in 2024 and Enbridge HER+ closed December 31, 2025. If you pair a new furnace with a qualifying Lennox heat pump (dual-fuel hybrid), the heat pump portion may qualify for the Ontario Home Renovation Savings program. See our Ontario heat pump rebates guide.
