The Elite EL297V is our "Premium" system, boasting a 97% AFUE rating, a Lifetime Limited Warranty on the heat exchanger, and a superior cabinet structure designed for maximum durability and heat retention. Beyond the efficiency, the Elite series offers much better control over airflow, allowing it to integrate more effectively with advanced heat pump systems for a true dual-fuel setup. It also provides enhanced humidity control and uses SilentComfort™ technology for whisper-quiet operation. The Merit ML296V is our "High-Value" 2-stage option, offering a 96% AFUE rating and a 20-Year Warranty on the heat exchanger.
Lennox has been a leader in the HVAC industry for over a century. It offers the best balance of fair pricing and high-end quality. Here is why it is the top choice for Canadian homeowners:
Proven Technology: From superior cabinet structures to advanced humidity control and seamless heat pump integration, Lennox leads in innovation.
Perfect Warranty: Their comprehensive warranties are among the best in the business, protecting your investment for decades.
Technician Familiarity: Because Lennox has been in Canada for 100+ years, almost every licensed gas technician is familiar with troubleshooting and servicing these units.
Parts Availability: You never have to worry about a "backorder" during a cold snap; genuine Lennox parts are widely stocked across Ontario.
Low Maintenance: Built for durability, these systems require minimal maintenance to stay at peak performance.
Important Note: Even the best furnace will fail if installed poorly. A bad installation can cut the unit's lifespan in half, void your manufacturer warranty, and ultimately cost you double when you have to hire a second company to fix it. Choosing a certified expert like 4Most Energy ensures it’s done right the first time.

While our product page provides a general sizing guide based on square footage, a "one-size-fits-all" approach can lead to inefficiency. 4Most Energy technicians perform a detailed heat-load calculation, considering your home’s insulation, window quality, and ceiling height, to ensure the unit is perfectly sized.
Note: Bigger is not always better. An oversized furnace will heat the air too quickly and shut off before it has properly circulated (a process called "short-cycling"). This leads to hot and cold spots throughout the house, higher energy bills due to frequent startups, and increased wear and tear that shortens the life of your furnace.
Rebates are currently available specifically for Heat Pump systems. However, once you match a Lennox high-efficiency furnace with a qualified heat pump system, you become eligible for significant energy-efficiency rebates through programs like the Enbridge Home Efficiency Rebate Plus. Ask our technicians to find the best match for your home and provide the latest news on available rebate amounts.
Yes. 4Most Energy includes a 1-Year Complimentary Labour Warranty on every installation to ensure your system is running perfectly from day one. For long-term peace of mind, we also offer a 10-Year Lennox Labour Warranty (sold separately). Because this plan is provided directly by Lennox, it is valid anywhere and remains active even if you receive service from another contractor in the future.
The Elite EL297V is a sophisticated piece of equipment with a two-stage gas valve and variable-speed motor. 4Most Energy is factory-trained specifically on Lennox systems. This ensures that the performance calibration—adjusting gas pressure and airflow—is done correctly, ensuring the unit actually operates at its rated 97% efficiency.
Most standard furnace replacements are completed within 4 to 6 hours. Our process includes the safe removal of your old unit, precision installation of the new Lennox system, and a full performance test to ensure everything is running perfectly before we leave.
Yes. We provide flexible financing options to make your home comfort upgrade more affordable. You can finance your new system for up to 5 years with a fair interest rate (subject to credit score approval). Additionally, we offer a 3-month no-interest plan for those looking for shorter-term flexibility. Speak with our experts during your quote consultation to find the best plan for your budget.
We strongly recommend avoiding furnace rental agreements. Renting often leads to extremely high long-term costs, can result in a lien on your property, and usually carries massive penalties if you try to terminate the contract early.
Many homeowners rent just for the "included maintenance," but this is a costly trap. Instead, we suggest financing your unit to own it outright and subscribing to our Maintenance Plans for less than $18/month, which you can cancel anytime with no penalty. Remember, every Lennox furnace already comes with a 10-year worry-free parts warranty, so you are already protected without the high cost of a rental.
