Is a single-stage heat pump a good fit for Ontario winters?

It depends on your specific location and how the system is set up. A single-stage heat pump like the EL16KP1 runs at one fixed output — fine for many homes in our service area, though homeowners in colder pockets of Simcoe or north Durham sometimes prefer a variable-speed cold-climate model like the KeepRite Ion 23 or Mitsubishi FX Hyper-Heat for steadier low-temperature performance. We'll help you compare options for your address.

What does 8.5 HSPF2 mean in practice?

HSPF2 measures how efficiently the heat pump converts electricity into heat over a full heating season — higher is better. 8.5 is a solid, mid-range figure for a single-stage heat pump; premium variable-capacity models can reach into the low double digits.

Does the EL16KP1 qualify for a rebate?

Heat pumps like this one fall into the equipment category eligible under Ontario's current electrification rebate programs. Rules and rebate amounts change, so we confirm current eligibility directly with you rather than quote a number that might no longer be accurate.

What size EL16KP1 do I need?

It's available from 1.5 to 5 tons. We size any heat pump off an in-home load calculation — your home's insulation, window area and ductwork all factor in — rather than matching the tonnage of your existing furnace or AC.

What warranty does the EL16KP1 carry?

Lennox backs the compressor with a 10-year limited warranty and parts with a 5-year warranty that extends to 10 years once registered after installation, which we handle as part of the job.
