Lennox Products We Install and Recommend
We don’t push what you don’t need. Our job is to recommend the right Lennox system for your home’s size, layout, and budget. Here’s what we install most often and why it works.
Lennox Furnaces
From the budget-friendly Merit Series to the ultra-efficient Signature Collection, Lennox gas furnaces are built for Canadian winters. We’ll help you choose between single-stage, two-stage, or modulating models based on your comfort needs and insulation.
Lennox Air Conditioners
Lennox AC units offer some of the highest SEER ratings in the industry. That means better cooling and lower bills, even during long summer heatwaves. Perfect for Toronto-area homes that need reliable cooling without overpaying for hydro.
Lennox Heat Pumps
For homeowners looking to move away from traditional HVAC systems, Lennox heat pumps offer heating and cooling in one system. They’re efficient, eco-friendly, and a smart way to reduce reliance on natural gas.
Lennox Air Purifiers and Indoor Air Quality Systems
We also install Lennox PureAir™ systems, humidifiers, dehumidifiers, and filtration units. These add-ons are great for families with allergies, asthma, or anyone who wants cleaner indoor air year-round.
