Lennox HVAC Systems From the Valley's Premier Dealer
Champion Air is a Lennox Premier Dealer and 2025 Dave Lennox Award winner. Merit, Elite, and Dave Lennox Signature systems — matched to your home and Arizona's heat.
Why Lennox
Why is Lennox our primary equipment line?
Because it has earned the spot. Champion Air installs Lennox as our primary line for one reason: after 40+ years and thousands of Valley installations, Lennox variable-capacity systems have proven they hold up to Phoenix summers while keeping energy bills in check. Lennox recognized that work with the 2025 Dave Lennox Award — the brand's highest dealer honor — and with Premier Dealer status, the top certification a Lennox dealer can hold.
Premium equipment deserves premium installation. Every Lennox system we install starts with a Manual J load calculation, is installed by factory-trained technicians, and is backed by our ChampionCare maintenance plans and 0% financing up to 60 months.

Merit · Elite · Signature
Which Lennox collection is right for a Phoenix summer?
All three collections survive Phoenix heat — the difference is how efficiently and how quietly they do it. Here's the honest breakdown.
Dependable comfort, budget-friendly
Merit Collection
Single-stage cooling with corrosion-resistant cabinets and the reliability Lennox is known for — top-quality comfort at prices that fit any budget. SEER2 ratings up to 18.
Best for: Rentals, smaller homes, and replacements where upfront cost leads the decision.
Variable-capacity value
Elite Series
Variable-capacity compressors deliver efficient, even comfort with SEER2 ratings up to 22.50 and sound levels as low as 60 dB. Most models are ENERGY STAR certified.
Best for: Most Valley families — the sweet spot of efficiency, comfort, and price.
The flagship line
Dave Lennox Signature Collection
The premiere Lennox line: variable-speed systems like the SL25XPV heat pump and SLP99V furnace, with cooling SEER2 ratings from 21 to 28 and sound levels as low as 58 dB.
Best for: Homeowners who want maximum efficiency, the quietest operation, and total climate control.

How do variable-capacity Lennox systems handle 115° days?
By never sprinting. A single-stage AC is either off or at 100%, slamming on and off through a 115° afternoon. Variable-capacity Lennox systems — the Elite and Dave Lennox Signature collections — adjust output in small increments and run long, steady cycles at partial capacity. That means tighter temperature control, less strain on the compressor during the hottest hours, and quieter operation (as low as 58 dB on Signature systems) while the system works all day.
Can a Lennox system lower APS or SRP time-of-use bills?
That's where variable capacity pays for itself. On APS and SRP time-of-use plans, electricity costs the most in the late-afternoon peak window. A variable-capacity system paired with a Lennox iComfort thermostat can pre-cool your home during cheaper off-peak hours, then coast through the peak at low capacity instead of running flat-out at the most expensive time of day. As an APS Qualified Contractor and SRP Trade Ally, we'll also flag any rebates your installation qualifies for. See real numbers on our transparent pricing page.

Lennox Questions, Answered First

What is the difference between Lennox Merit, Elite, and Dave Lennox Signature?
Merit is the budget-conscious single-stage line (SEER2 up to 18). Elite adds variable-capacity compressors and higher efficiency (SEER2 up to 22.50). The Dave Lennox Signature Collection is the flagship: variable-speed systems with SEER2 ratings from 21 to 28 and the quietest operation Lennox makes.
Is Lennox a good brand for Arizona heat?
Yes. Variable-capacity and variable-speed Lennox systems are engineered to run long, efficient cycles instead of hard stop-start cycling, which is exactly what 110°+ Phoenix afternoons demand. Champion Air performs a Manual J load calculation so the system is sized for your home, not a rule of thumb.
Can a Lennox system help with APS or SRP time-of-use plans?
It can help you manage them. A variable-capacity Lennox system paired with an iComfort smart thermostat can pre-cool your home before on-peak hours and then run at low capacity through the peak window, shifting much of the cooling work to cheaper hours. Champion Air is an APS Qualified Contractor and SRP Trade Ally and can walk you through rebate options.
What warranty comes with a Lennox system from Champion Air?
Lennox limited warranties vary by collection — Signature and Merit systems include 10-year parts and compressor coverage, and Signature furnaces carry lifetime heat-exchanger coverage. Ask your comfort advisor for the exact registered-warranty terms for the model you choose.
How much does a new Lennox system cost in Phoenix?
It depends on tonnage, collection, and installation scope. Champion Air publishes transparent price ranges on our pricing page, offers 0% financing up to 60 months, and provides free in-home estimates with no obligation.
