Why homeowners choose the Lennox ML193E

The Lennox ML193E is a single-stage, 93% AFUE gas furnace from the Merit® Series. It pairs sealed-combustion efficiency with a power-saving constant-torque blower, which makes it a strong-value replacement for smaller or well-insulated homes — and a furnace that holds up to a real Simcoe County winter.

  • 93% AFUE sealed combustion — efficient, clean-burning heat
  • Power Saver™ constant-torque blower draws less electricity than a standard motor
  • Dual-fuel ready — it can pair with a heat pump later, which is the side that earns the Ontario rebate
  • 20-year limited heat-exchanger warranty; 5-year parts (10-year with registration)

A good fit if…

  • Homeowners replacing an older mid-efficiency furnace on a sensible budget
  • Smaller or well-insulated homes that do not need two-stage modulation
  • Anyone who wants reliable, efficient heat without paying for premium comfort features

Frequently Asked Questions

No. At 93% AFUE the ML193E does not meet the ENERGY STAR Canada furnace threshold, so we do not badge it as ENERGY STAR. It is still a high-efficiency, sealed-combustion furnace — if ENERGY STAR matters to you, look at the 96–97% AFUE models.
A standalone gas furnace is largely not rebated in Ontario right now — the Home Renovation Savings Program puts its money toward heat pumps. The ML193E is dual-fuel ready, so pairing it with a heat pump can open up to $7,500 in rebates. We confirm exactly what your home qualifies for at the quote.
It comes in five sizes from 44,000 to 132,000 BTU/h. We run a heat-loss calculation on your home before recommending a size — oversizing a furnace causes short-cycling, uneven temperatures, and a shorter lifespan.
