The Lennox Difference
Why Lennox Is Known for Quiet Operation & Premium Efficiency
Lennox consistently earns top marks for the quietest operation and highest SEER2 ratings in residential cooling — a strong choice for homeowners who want the best.
Whisper-Quiet Operation
Lennox is widely recognized as one of the quietest AC brands available. Their XC series systems operate as low as 59 decibels — quieter than a normal conversation — making them ideal for bedrooms and open-plan living spaces.
Premium Energy Efficiency
Lennox leads the industry in SEER2 ratings. The XC21 reaches up to 28 SEER2 — among the highest available in residential cooling — delivering significant energy savings over the long Florida cooling season.
Superior Humidity Control
Lennox variable-speed systems modulate output to match your home's exact cooling demand. The result is more consistent temperatures, dramatically better humidity removal, and true comfort — not just cold air.
Strong Warranty Coverage
Lennox backs their equipment with a 10-year limited warranty on parts and compressor when registered within 60 days of installation. Proper installation by an experienced dealer is essential to activate full coverage.
Smart Home Integration
Lennox iComfort systems pair seamlessly with the iComfort S30 smart thermostat, giving you precise zone control, remote access, and energy monitoring — all from your phone.
Why It Matters
Why Choose a Local Expert Over a National Chain for Your Lennox System
Lennox systems reward proper installation and penalize shortcuts. A local team with real Lennox experience makes a measurable difference in performance, efficiency, and system life.
Technicians Who Know Lennox
Our technicians have hands-on experience with Lennox XC, EL, and ML series systems — not just general HVAC training. When your Lennox system needs service, you want someone who has worked on that exact equipment before.
Proper Installation Standards
Lennox systems are precision-engineered. Improper installation — wrong refrigerant charge, incorrect airflow, skipped commissioning steps — reduces efficiency, shortens system life, and voids your warranty. We do it right.
Warranty Compliance
Lennox's 10-year warranty requires registration within 60 days and proper installation. We handle warranty registration as part of every installation — your coverage is activated before we leave your driveway.
Local Accountability
National chains rotate technicians and answer to a call center. Double A has served Northeast Florida since 2003. We live here, we work here, and our reputation depends on every job we do.
Same-Day Service
When your Lennox system goes down in the Florida heat, you need a local team that can respond fast — not a national dispatch queue. Double A offers same-day service throughout Jacksonville and NE Florida.
Manual J Load Calculation
We size every Lennox system using Manual J load calculations. A premium Lennox unit installed at the wrong size will short-cycle, struggle with humidity, and wear out years ahead of schedule.
What Jacksonville Homeowners Say
700+ five-star reviews across Northeast Florida
“Double A installed a Lennox XC system in our home two years ago and it is the quietest AC we have ever had. You can barely hear it running. The installation was meticulous — they did a load calculation, checked every connection, and registered the warranty before they left. Outstanding.”
