Two of the biggest names in the central heat pump industry have been going head-to-head for decades to dominate the market for central heating and cooling systems. At AirGreen, we’ve installed and serviced both Trane and Lennox units all across Montréal, Laval, Longueuil, the North Shore and the South Shore. Backed by this real-world experience, we’ve decided to bring you a full comparison—based not on generic spec sheets, but on actual performance in real-life conditions, on the specific needs of our customers, and on how these systems hold up over time.
Trane and Lennox: Two HVAC Philosophies, One Promise – Comfort
While both American brands are globally recognized, they take different approaches in terms of design, energy performance, and built-in technology. This showdown deserves a deep dive to guide residential and commercial owners in choosing the right central heat pump.
Energy Efficiency: A Tight Battle Between Performance and Consistency
Both brands aim for cutting-edge technology to reach the highest standards of energy efficiency. Trane stands out with its models boasting high SEER2 and HSPF2 ratings, especially the XV20i series, which offers impressive variable speed modulation. Lennox counters with its Dave Lennox Signature line, and its SL25XPV model, which can hit a SEER2 rating of up to 24 in certain configurations.
At AirGreen, we’ve noticed that top-end Lennox models deliver exceptional efficiency, but require very precise calibration during installation to perform at their best. Trane, on the other hand, consistently delivers reliable performance even in extreme conditions, particularly during the brutal Québec winters, making it a preferred choice on the North Shore.
Reliability and Durability: Trane Takes the Lead in the Field
Our HVAC technicians have seen it time and again: Trane units tend to withstand the test of time better, even after several harsh winters in areas like Boisbriand, Saint-Jérôme or Terrebonne. The mechanical components, the exclusive Climatuff compressor, and overall build quality offer exceptional ruggedness.
That’s not to say Lennox isn’t reliable—far from it. However, its high-performance MERV 16 filtration system demands regular maintenance, otherwise performance drops—especially in more urban settings like Laval or Longueuil, where indoor air pollution can be a factor.
Ease of Installation and Servicing: A Strategic Edge for Trane
As a company specializing in central heat pump installation, we have to highlight that Trane offers a more standardized design, which simplifies installation and limits surprises. In contrast, Lennox often requires specific configurations and advanced software calibration. This means a less experienced installer may not get optimal performance from a Lennox system.
AirGreen, with its mastery of high-end brands, is well-positioned to install both without compromise. However, on more complex jobs—like a century-old home in Old Longueuil or a condo in the Plateau—Trane systems often give us more technical flexibility.
Comfort and Technology: Lennox Shines with Smart Features
Lennox often outshines Trane when it comes to smart home connectivity and intelligent controls. Its iComfort thermostats, seamless integration with home automation systems, and remote management capabilities appeal to tech-savvy clients, especially in Brossard, Laval-des-Rapides or Griffintown.
That said, Trane holds its own. Their Nexia thermostat offers solid features, though it’s sometimes less user-friendly. For users who want simple, robust, and efficient technology, Trane remains a solid choice.
Rebates and Climate Efficiency: Both Brands Qualify
Both brands offer models that qualify for Hydro-Québec’s LogisVert grants. We’ve installed 3-ton Trane central heat pumps in Laval, and Lennox SL25XPV units in Longueuil, both of which qualified for rebates up to $5,000, depending on configuration and energy performance.
Our AirGreen team handles eligibility analysis and paperwork for grant applications, whether you choose Trane or Lennox.
Real-World Case Studies: Feedback From the Field
Project 1 – Montréal-Nord: We installed a Lennox EL18XPV central heat pump in a two-story intergenerational home. The client wanted a discreet, efficient, and ultra-quiet central system. Result: steady thermal comfort even during heat waves—but required a few days of fine-tuning for optimal settings.
Project 2 – Sainte-Thérèse: A commercial building needed an ultra-sturdy system. We went with a Trane XV18 and custom plenum. Result: a system that runs nonstop, without fluctuation, even at -25°C. The client, a property manager, praised the flawless reliability after two years of intensive use.
