About the Lennox EL18KSLV Heat Pump

Who this heat pump is for

This unit fits homeowners across Toronto, the GTA, and Barrie who want a single system that handles both summer cooling and shoulder-season heating, and who are comfortable pairing it with a gas furnace as backup for the coldest stretches of January. Sizing follows a Manual J load calculation, not the BTU of whatever you’re replacing: oversized heat pumps short-cycle and underperform.

Why customers pick Lennox

Lennox sits at the premium end of the residential HVAC market. The brand pioneered ultra-high efficiency variable-capacity systems and has been a go-to for homeowners who value quiet operation, tighter temperature control, and longer equipment life over upfront price.

Installation notes

Heat pump installation involves the outdoor condenser, an indoor evaporator coil matched to the same tonnage, refrigerant line set, electrical disconnect, condensate management, and a thermostat capable of running heat pump logic with auxiliary heat staging. Permit and electrical inspection apply in Ontario.

Warranty and rebates

Most Lennox heat pumps in this category carry a 10-year limited warranty on the compressor and parts when registered. Heat pump installs are also the strongest rebate category in Canada right now: Enbridge Home Efficiency Rebate Plus and the federal Canada Greener Homes ecosystem can stack up to thousands of dollars off a qualifying install.
