About Lennox HVAC

Lennox has been an HVAC innovator since 1895 and dominates the high-SEER and premium-comfort market. We service the full Lennox lineup: Lennox Signature SL28XCV, EL16XC1, and Merit-series condensers and heat pumps.

Common Lennox repairs we handle

iComfort thermostat pairing
Variable-speed inverter board diagnostics
Coil leak detection
Pressure-switch / flame-sensor repair on G71MPP furnaces

If your Lennox system is making strange noises, short-cycling, blowing warm air, or showing an unfamiliar error code, our Pre-Flight Check diagnostic will pin down the cause on the first visit.

Lennox installation, replacement & tune-ups

Need Lennox service in San Diego County?

We install and service Lennox systems across Chula Vista, the South Bay, East County and North County. Our technicians are NATE-certified and EPA Section 608 certified for refrigerant handling, and we stock the parts that most often fail on Lennox equipment, so the majority of repair calls finish the same day rather than turning into a parts-ordering exercise.

If you are weighing a Lennox system against another brand, we will give you a straight comparison rather than a sales pitch. We carry multiple lines, so the recommendation you get is based on what fits your house, your load calculation and your budget. Every installation quote includes an ACCA Manual J sizing calculation, and we will tell you which SDG&E rebates the equipment actually qualifies for. Note that the federal 25C tax credit ended on December 31, 2025, so if another company is still quoting you a federal credit on a new system, that number is no longer real.
