Why Lennox Is a Strong Choice for South Florida Homes
Florida homes demand efficiency and humidity control more than anywhere else in the country — exactly where Lennox excels.
- Best-in-class efficiency: The Lennox SL25XPV heat pump reaches up to 23.5 SEER2, and the XC25 air conditioner tops 26 SEER2 — genuine energy-bill reductions in a nine-month-per-year cooling climate.
- Humidity control: Lennox Precise Comfort® technology modulates in 0.5% increments, letting the system run longer at low output to hold indoor humidity around 50% RH — the sweet spot for comfort and mold prevention.
- Coastal durability: Lennox outdoor units use galvanized steel cabinets with baked-on powder coating to resist salt-air corrosion near Boca Raton’s, Fort Lauderdale’s, and Sunny Isles’ coastlines.
- Warranty: 10-year parts limited warranty on most residential equipment when registered, stacked with Atlantic Air’s 12-year labor warranty.
Lennox Models We Install in South Florida
We install the complete Lennox residential lineup. The right system depends on your home’s load, ductwork, and efficiency goals.
- Lennox Signature Series (SL25XPV, XC25, SL18XP1): Top-tier variable-capacity heat pumps and air conditioners up to 26 SEER2. iComfort® S30 communicating controls and the best humidity performance Lennox makes — ideal for larger homes in Palm Beach Gardens and Weston.
- Lennox Elite Series (EL18XPV, XP16, EL16XC1): Two-stage heat pumps and ACs from 16–19 SEER2. Strong humidity control at a more approachable price — the value sweet spot for Boynton Beach and Plantation homes.
- Lennox Merit Series (ML14XC1, ML17XC1): Reliable single-stage systems from 14.3–17 SEER2 for budget-conscious replacements in starter homes and condos.
- Lennox Mini-Split Heat Pumps (MPB, MLB): Ductless single- and multi-zone options for lanais, additions, and older homes without ductwork — popular in Miami Beach and Coral Gables.

Frequently Asked Questions
What is the price range for a Lennox AC installation in Florida?
A 3-ton Lennox residential install in South Florida typically runs $7,000 for a Merit-series single-stage system up to $16,000+ for a Signature SL25XPV variable-capacity heat pump with iComfort S30. Pricing depends on tonnage, SEER2, ductwork, and permitting. Free written estimates and 0% APR financing up to $25,000 are available.
Does Lennox hold up to Florida humidity?
Yes — particularly the Signature and Elite variable-capacity models. Lennox Precise Comfort technology modulates in tiny increments, so the unit runs long low-capacity cycles that pull more moisture out of the air. Homes with Lennox variable-capacity often maintain around 50% indoor RH all summer.
How long does a Lennox AC last in South Florida?
A well-maintained Lennox residential system in our climate typically lasts 12–16 years. Coastal installations benefit most from semi-annual coil washes to prevent salt-air corrosion on the outdoor unit.
Are you Lennox-certified?
Yes. Our technicians are NATE-certified and trained on current Lennox residential platforms, including iComfort S30 communicating controls, Harmony III zoning, and Precise Comfort variable-capacity heat pumps. We install genuine Lennox parts and register every system for the factory warranty.
Do you install Lennox mini-splits for lanais or additions?
Yes. Lennox MPB and MLB single- and multi-zone mini-splits are a great fit for lanais, garages, and additions in coastal South Florida homes. We size, permit, and install — usually in one day.
