The Lennox ML193E Furnace Review covers Lennox’s most budget-friendly gas furnace, designed for homeowners who want basic, dependable heating at a lower upfront cost. Part of the Merit® Series, the ML193E focuses on durability and quiet operation rather than top-tier efficiency.
With a 93% AFUE rating, this model falls below Canada’s current high-efficiency benchmark (95%+), which means it may not qualify for rebates and may have limited availability in some regions. Still, for smaller homes or milder climates, the ML193E can provide reliable comfort without the price tag of higher-end Lennox furnaces.
Average Installation Cost (Canada): $4,000 – $4,500
AFUE Efficiency: 93%
Heating Stages: Single-stage
Blower Motor: Constant torque
ENERGY STAR® Certified: No
Best For: Budget-focused buyers, smaller homes, mild climates
Lower upfront installation cost compared to Elite and Signature models

Note: This model does not meet Canada’s minimum efficiency requirement for gas furnaces (95% AFUE), so availability may be limited.
The Lennox ML193E Furnace Review is a straightforward, entry-level furnace that prioritizes reliability and quiet performance over maximum efficiency. While it includes useful features like a constant torque blower, condensing design, and dual-fuel capability, its 93% AFUE efficiency limits long-term energy savings and rebate eligibility in Canada.
For homeowners on a tight budget or in milder climates, the ML193E can still be a practical option. However, those looking for better efficiency, lower operating costs, and future-proof performance should strongly consider stepping up to a higher-efficiency Lennox model.
| Specification | Details |
|---|---|
| AFUE | 93% |
| Burner Type | Single-stage |
| Blower Type | Constant torque |
| ENERGY STAR® | No |
| Heat Exchanger | Duralok Plus® |
| Ignition | SureLight® silicon nitride |
| Dual-Fuel Ready | Yes |
The ML193E includes several Lennox-exclusive components focused on durability and steady performance:
Power Saver™ Constant Torque Motor – Maintains consistent airflow while improving comfort
SureLight® Silicon Nitride Ignitor – Reliable, long-lasting ignition without a standing pilot
Duralok Plus® Heat Exchanger – Clamshell design enhances heat transfer and reduces air leakage
Sealed Blower Compartment – Limits noise and minimizes air loss
Pre-fabricated installation features such as flanges and flue collars help simplify setup and reduce installation time.
With a 93% AFUE, the ML193E converts most—but not all—of its fuel into usable heat. Compared to 95%+ furnaces, it allows more heat to escape through exhaust gases, which can lead to higher heating costs over time.
The single-stage burner operates at one output level, providing steady heat but less flexibility during milder weather. This makes the ML193E better suited for smaller homes or regions with shorter heating seasons.
Quiet operation is one of the ML193E’s strengths. A reinforced blower assembly, sealed burner box, and insulated cabinet help keep sound levels low, making it a good choice when the furnace is installed near living areas.
The ML193E is compatible with the Lennox iComfort® M30 Smart Thermostat, enabling:
Geofencing temperature adjustments
Voice control via Alexa, Google Assistant, and Apple HomeKit
Improved temperature and humidity balancing
Smart home integration through IFTTT
Lennox provides solid warranty protection for an entry-level furnace:
20-Year Limited Heat Exchanger Warranty
10-Year Limited Parts Warranty (registration required within 60 days)
If not registered, parts coverage drops to 5 years. Professional installation and regular maintenance are required to keep warranties valid.
Pros
Lower upfront installation cost
Quiet and reliable operation
Dual-fuel compatibility
Smart thermostat support
Durable Lennox components
Cons
93% AFUE does not meet Canada’s high-efficiency standard
No ENERGY STAR® certification
Limited rebate eligibility
Higher long-term operating costs than 95%+ models
The EL296V is a major upgrade from the ML193E. It’s a two-stage, variable-speed furnace with an AFUE of 96%, offering:
Quieter operation
Better humidity control
Greater energy savings
Eligibility for rebates
| Feature | ML193E | ML296V |
|---|---|---|
| AFUE | 93% | 96% |
| Heating | Single-stage | Two-stage |
| Blower | Constant torque | Variable-speed |
| Best For | Lowest upfront cost | Better efficiency & comfort |
While the EL296V costs more ($6,800 – $7,400 installed), it’s a stronger long-term investment for Canadian homes.
The SLP99V is Lennox’s top-of-the-line model with a 99% AFUE, variable-capacity burner, and modulating airflow. It can fine-tune performance in 1% increments, offering:
Maximum comfort and energy savings
Whisper-quiet operation
Smart thermostat integration with advanced system diagnostics and air quality management
| Feature | ML193E | EL296V |
|---|---|---|
| Series | Merit | Elite |
| AFUE | 93% | 96% |
| Comfort Level | Basic | High |
| Rebate Potential | Low | Higher |
If you want the best efficiency and performance possible, the SLP99V leads the market.
The ML296V belongs to the same Merit series but offers much better value:
AFUE: 96%
Burner: Two-stage
Blower: Variable-speed
While it costs slightly more, it provides:
More even heating throughout the home
Lower long-term energy costs
Potential rebate eligibility
| Feature | ML193E | SLP99V |
|---|---|---|
| AFUE | 93% | 99% |
| Heating | Single-stage | Modulating |
| Price Tier | Budget | Premium |
| Best For | Basic needs | Maximum efficiency & comfort |
In short, the ML296V is a more balanced and future-proof option for most Canadian homeowners.
The Lennox ML193E is a basic, entry-level gas furnace best suited for smaller homes or milder climates. It’s durable, quiet, and reliable—but falls short of the efficiency and rebate qualifications needed in most Canadian regions.
If budget is your top priority, it’s worth considering—but for lasting performance and savings, the ML296V or EL296V are stronger choices.
