About the Lennox SL28XCV Air Conditioner

Who this air conditioner is for

This Lennox condenser is sized for a defined slice of GTA homes: undersized for a 3,500 sq ft poorly insulated bungalow, oversized and short-cycling for a 1,200 sq ft condo. The right pick comes from a Manual J load calculation that accounts for window area, insulation, ductwork, and shading, not from the size of whatever’s already sitting beside the house.

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

An AC swap looks simple from the curb but involves an AHRI-matched indoor evaporator coil sized to the new condenser, a fresh refrigerant line set or properly flushed existing lines, a 240V disconnect, condensate drainage, a level pad, and clearance for service access. Modern refrigerants (R-454B / R-32 on 2025+ units) also bring updated handling and storage requirements that DIY installs miss.

Warranty and rebates

Lennox typically offers a 10-year limited parts warranty on this category when the unit is registered within 60 days. Higher-SEER2 condensers (16+) often qualify for utility rebates through Enbridge Home Efficiency Rebate Plus when bundled with other upgrades.
