Frequently Asked Questions
What SEER2 rating should I look for in a GTA home?
Canada’s minimum efficiency standard for new central AC installations is 13.4 SEER2 as of 2023. Most GTA homeowners choose 17–20 SEER2 for a good balance of upfront cost and long-term energy savings. The Lennox XC20 at 20 SEER2 or Mitsubishi H2i at 33.1 SEER2 are excellent choices for homeowners wanting top efficiency.
What size AC unit do I need?
Most GTA homes need 1.5–5 tons of cooling capacity. Correct sizing requires a Manual J cooling load calculation based on your home’s square footage, insulation, window area, and orientation. An oversized unit will short-cycle, creating humidity problems and higher energy bills. We perform a full load calculation on every free in-home assessment.
Should I choose a heat pump instead of a central AC?
If you’re replacing both your furnace and AC at the same time, a Lennox cold-climate heat pump paired with a gas furnace is often a better investment — it provides both heating and cooling in one outdoor unit, reduces energy costs, and may qualify for available Ontario rebates.
