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
