Every brand has its quirks. Here are the failure patterns we see most often on Lennox systems in the South Bay climate:
10-year parts warranty. Up to lifetime compressor warranty on select units.
When we do warranty work on Lennox systems, we handle the warranty claim paperwork on your behalf — meaning we file the claim, source the OEM replacement part through our distributor, and only invoice you for labor (which is rarely covered under most Lennox parts warranties beyond year one). Manufacturer warranties honored on all parts.

Popular Lennox models we service in South Bay include: XC25, XC21, XP21, EL18XCV.

For less-common models, we typically have parts within 24 hours via our distributor.

“Industrial neighborhood, our condenser eats a lot of airborne crap from the port. They include a deep coil-cleaning twice a year as part of the membership and have a special agreement on a marine-grade dielectric coating. System is 8 years old and still operating at 92% of nameplate capacity per their measurements. Better than I had any right to expect for the location.”

“Pre-war home with patched flex duct in the attic — Title 24 leakage test failed at 32% (passing is 5%). They replaced the worst runs with R-8 insulated flex, sealed plenums with mastic, and got us down to 7%. Energy bill dropped $48/month and the rooms over the garage finally stay warm in winter. Highly recommend if you've got an older house.”

“Switched from gas furnace to a Mitsubishi M-Series Hyper-Heat (cold-climate-rated even though we don't need it). They oversized the line-set, ran the condensate to an existing trap, and rebalanced the duct system because heat pumps need higher airflow. System runs in heating mode at 12°F outdoor without backup heat. Bills are noticeably lower.”

“Zone-controlled house — old Honeywell zoning panel, two thermostats. They installed two Ecobee Premium units, configured the zoning panel correctly (lots of techs get this wrong), and integrated everything with our HomeKit. Took longer than planned because the C-wire wasn't pulled at one stat — they had to fish through a wall. Done right but lost a star for the time overrun.”

“Old Goodman from 2003 finally died. Replaced with an American Standard Platinum 18 (matched evaporator coil + air handler). Crew was meticulous — vacuumed to 350 microns, weighed in the charge, did a static-pressure test post-install (came in at 0.38 in. wc, well within spec). Also fixed a duct collapse they noticed in the attic for free. Five-star work all the way.”

“Carrier 59TN furnace (Hot Surface Ignition) wouldn't fire. Tech diagnosed a failed control board (CESO110057-02) — common on this model around year 12. Had a refurbished board on his truck (with a 3-year warranty), saved us $180 vs a new one. Total visit: 70 minutes. Technically minded, doesn't talk down to you, doesn't try to upsell.”
