Variable-capacity operation adjusts output to match the day, holding steady temperatures and running remarkably quietly — ideal for bedrooms and patios nearby.

Premium Reliability

Well-engineered and backed by strong manufacturer warranties when registered — a sound long-term investment for your home's comfort.

The Lineup

The Lennox AC Lineup

Signature XC25: variable-capacity flagship at up to 26 SEER2 — the quietest, most efficient, most precise cooling Lennox makes. Elite XC20 / XC16: two-stage and single-stage units balancing efficiency and value for most GTA homes.

Merit series: dependable cooling at Lennox's most accessible price. Because Toronto's cooling season is shorter than hotter climates, we'll help you weigh premium efficiency against payback — see our air conditioning page for the full process and sizing approach.

FAQ

Lennox Air Conditioner Questions

Installed Lennox central AC in the GTA generally runs from about $4,500 for a Merit-series unit to $9,500+ for a top-tier Signature XC25, depending on size (tonnage), SEER2 rating, and any line-set or electrical work. The quote includes equipment, labour, refrigerant, the required permits, and inspection — a fixed written price before we start.
The Lennox Signature Collection XC25 is the flagship — a variable-capacity central AC reaching up to 26 SEER2, among the most efficient and quietest residential air conditioners available. Below it, the Elite XC20/XC16 and Merit series offer strong efficiency at lower price points. For Toronto's cooling season we'll help you weigh premium efficiency against payback.
For most GTA homes, 16–18 SEER2 hits the sweet spot. Toronto's cooling season runs roughly June through August, so the payback on ultra-premium 22–26 SEER2 units is longer here than in hotter climates — though if you run AC heavily or plan to stay 15+ years, the premium Lennox models do pay back. We run the numbers for your home.
