Why Lennox Is the Premium Choice
Lennox International has been manufacturing HVAC equipment since 1895 and is consistently ranked among the top heating and cooling brands in North America. Their engineering focus is on efficiency and quiet operation: the flagship Dave Lennox Signature® Collection SLP99V furnace achieves up to 99% AFUE, meaning virtually all the energy consumed is converted directly into heat for your home. Their air conditioners reach SEER ratings of up to 28, placing them at the top of the industry for cooling efficiency.
What sets Lennox apart from budget brands is the technology inside the equipment. Premium Lennox furnaces use variable-capacity modulating gas valves that adjust output continuously rather than cycling on and off at full blast: the result is more consistent temperatures, lower gas consumption, and significantly quieter operation. The same principle applies to their variable-speed air conditioners, which ramp up and down based on demand rather than running at full capacity until the thermostat is satisfied.
The trade-off is a higher upfront cost and a slightly more complex system that benefits from installation by an experienced contractor. Beyond HVAC technicians are trained on the full Lennox product range and understand the nuances of commissioning variable-capacity systems correctly. An improperly installed Lennox system will not deliver the efficiency or comfort it's designed for: proper sizing, refrigerant charge, and airflow calibration are all critical.

Lennox Furnace Repair & Maintenance
Lennox systems are engineered for longevity, but like any mechanical equipment, they benefit from annual maintenance and occasional repairs. Our technicians are experienced with the full Lennox product range, including the variable-speed motors and modulating gas valves found in the premium Signature Collection. We carry common Lennox parts and can source others quickly through our supplier network. Annual maintenance on a Lennox furnace typically includes a heat exchanger inspection, burner cleaning, igniter test, filter replacement, and a full operational check: everything needed to keep your warranty valid and your system running efficiently. For urgent repairs, we offer same-day service across the GTA. Learn more about our furnace repair service and heating maintenance programs.

Lennox HVAC Questions Answered
Is Lennox better than Goodman?
For most homeowners who plan to stay in their home for 10+ years, yes: Lennox is the better long-term investment. Lennox's premium Signature Collection furnaces and air conditioners use variable-capacity technology that Goodman's standard lineup does not offer at the same price point. The result is more consistent indoor temperatures, quieter operation, and meaningfully lower energy bills. Goodman is a reliable brand and a reasonable choice for budget-conscious buyers or rental properties, but if comfort and efficiency are the priority, Lennox is the stronger product. The trade-off is a higher upfront cost: typically $1,000–$2,500 more for a comparable installation.
What Lennox series should I buy?
It depends on your priorities and budget. The Dave Lennox Signature® Collection is the top tier: variable-capacity operation, near-silent performance, and the highest AFUE ratings available. We assess your home's heating load and walk you through the options before recommending a specific model. For most GTA homes, the Elite Series offers an excellent balance of efficiency and value. The Merit Series is a solid choice if upfront cost is the primary concern.
Does Beyond HVAC install Lennox heat pumps?
Yes. Lennox produces a range of cold-climate heat pumps suitable for Ontario winters. The XP25 and XP21 series are designed for variable-capacity operation and can maintain efficient heating in temperatures well below freezing. If you're considering a heat pump to replace or supplement your existing furnace, we can assess your home and recommend whether a Lennox heat pump, a dual-fuel system, or a traditional furnace-and-AC combination makes the most sense for your situation.
What warranty does Lennox offer?
Lennox warranty coverage depends on the product series and whether you register your equipment within 60 days of installation. The Dave Lennox Signature® Collection comes with 10 years on covered components and lifetime coverage on the heat exchanger with registration. The Elite Series offers 10 years on parts and 20-year heat exchanger coverage with registration. The Merit Series provides 5-year parts coverage and a 20-year heat exchanger warranty with registration. Beyond HVAC registers your Lennox equipment on your behalf at the time of installation and provides you with full warranty documentation.
How much does a Lennox furnace installation cost in the GTA?
A Lennox furnace installation in the GTA typically ranges from $3,500 to $7,500 installed, depending on the series, the size of the unit, and whether any ductwork or gas line modifications are required. The Dave Lennox Signature® Collection sits at the higher end of that range, while the Merit Series is more accessible. We provide a firm, itemized quote after assessing your home: no vague estimates. Financing is available through Financeit, including 0% interest options for qualified applicants.
Do you service existing Lennox equipment?
Yes. We repair and maintain all Lennox models, including older units. Common Lennox repairs include inducer motor replacements, igniter failures, pressure switch issues, and heat exchanger inspections. We carry common Lennox parts and can source others quickly. Annual maintenance on a Lennox system is recommended to keep the warranty valid and the system running at rated efficiency.
Are there rebates available for Lennox equipment in Ontario?
Yes. The Canada Greener Homes Grant and Enbridge Gas rebate programs offer incentives for high-efficiency HVAC upgrades, including qualifying Lennox furnaces and heat pumps. Eligibility depends on the specific model and your current equipment. We stay current on available programs and will flag any rebates you qualify for during the assessment: in some cases, rebates can offset $500–$5,000 of the installation cost.
