Lennox HVAC Review
Highest-efficiency residential HVAC made — but limited to factory dealers only.
Lennox sells the most efficient residential HVAC made (SL28XCV hits 28 SEER2 — top of the industry). Trade-off: only sold through Lennox Premier Dealers; parts can be slow to source outside that network.
Strengths
- Highest SEER2 ratings in the residential market (up to 28)
- SunSource solar-ready models
- Industry-leading variable-capacity tech
- Excellent humidity control
Weaknesses
- Closed dealer network — Premier Dealers only
- Parts harder to source — premium for service calls outside dealer network
- Higher repair costs
- Smaller dealer presence than Carrier/Trane in many markets

Frequently Asked Questions
Is Lennox a good HVAC brand?
Yes — best efficiency in the residential market. The catch is the closed dealer network: make sure you have a great Lennox Premier Dealer near you BEFORE you commit, because parts outside that network are slow + expensive.
Why is Lennox so efficient?
Proprietary variable-capacity inverter technology, larger heat-exchanger surface area, and tighter manufacturing tolerances. SL28XCV is the only residential unit currently hitting 28 SEER2.
