Lennox is known for the high-end Signature Collection (XC25, XC21) using iComfort communication. The Elite and Merit series are mainstream. Lennox systems tend to use proprietary parts that need brand-specific sourcing — SAVA carries common Lennox capacitors, contactors, and ignitor parts on the truck.

Frequently Asked Questions — Lennox AC Repair
Yes. SAVA repairs Lennox central air conditioners across Chicago and the suburbs — the Signature Collection, Elite and Merit series, including iComfort communicating systems. EPA Section 608 Certified.
iComfort thermostats losing their link to the outdoor unit, capacitor failures on the XC25 and XC21, condensate pump failures on high-efficiency models, refrigerant charge problems after a leak, and defrost board faults on heat pump versions.
Common capacitors and contactors are on the truck. Lennox uses a number of proprietary parts, which are sourced for the specific model when needed.
Lennox is a premium brand whose Signature Collection is one of the high-efficiency lines on the market; the trade-off is more proprietary parts and electronics to diagnose. Correct installation matters as much as the brand.
On a Lennox under about 10 years old, a repair is usually the better choice, especially on Signature models. When a compressor or coil fails past 12 to 15 years, replacement usually makes more sense. The repair price comes after the diagnostic.
The service call starts from $79 and includes a 30-minute diagnostic, credited toward the repair. Lennox repairs range from a capacitor to an iComfort control part, and the price is quoted after the diagnostic.
