Frequently Asked Questions

What is the highest SEER2 rating available from Lennox?

The Dave Lennox Signature Collection reaches up to 28 SEER2, making it among the highest-efficiency residential air conditioning systems available anywhere in the market. This level of efficiency is particularly valuable in Florida's extended cooling season — the operating cost savings over 15 years on a 28 SEER2 system vs. a 14 SEER2 minimum-efficiency unit can exceed $15,000 in a larger home.

What is the iComfort S30 thermostat?

The iComfort S30 is Lennox's flagship smart thermostat, compatible with Elite and Signature Collection systems. It provides full Wi-Fi connectivity, remote access, voice control (Alexa and Google Home), occupancy-based scheduling, indoor air quality monitoring, and detailed energy usage analytics. On a communicating Lennox system, the iComfort S30 can also monitor system performance and alert you to maintenance needs before they become failures.

Does Lennox offer solar-ready AC systems?

Yes — the Dave Lennox Signature Collection includes SunSource solar-ready models that can connect directly to a solar panel array for supplemental system power. In Florida, where solar adoption is high and FPL offers net metering, a SunSource system can further reduce your annual cooling costs beyond the efficiency gains of the system itself.

How does Lennox compare to Carrier in efficiency?

Lennox's Dave Lennox Signature Collection (up to 28 SEER2) edges out Carrier's Infinity Series (up to 26 SEER2) at the very top of the efficiency scale. In the mid-range, both brands are competitive — Carrier's Performance Series (16–19 SEER2) and Lennox's Elite Series (16–21 SEER2) overlap significantly. The best choice depends on your specific efficiency goals and budget — Top Notch Air Conditioning & Heating can run side-by-side comparisons for any system combination.

What warranty does Lennox provide?

Lennox's Merit Series comes with a 5-year limited parts warranty. The Elite and Signature Collection series offer a 10-year limited parts warranty with registration. The Signature Collection also includes compressor coverage in its 10-year warranty. We handle warranty registration on every Lennox installation.
