Dust and pollutants can circulate through your home, exacerbating allergies and respiratory issues.

Lennox heating and cooling systems are renowned for their high efficiency and advanced technology. Many Lennox systems utilize a multi-stage filtration process, which can sometimes lead to a buildup of particles within the ductwork if not properly maintained. Common configurations, such as the Lennox Merit and Elite series, often include additional features designed to enhance indoor air quality, such as variable-speed motors and advanced filtration systems. It's crucial for homeowners to understand that while these features improve overall performance, they can also lead to specific cleaning needs. Regular duct cleaning ensures that these advanced systems operate efficiently, preventing potential issues stemming from restricted airflow due to dirty ducts. Knowledge of the specific configuration of your Lennox system can help tailor the cleaning process to maximize performance.

Looking for duct cleaning on a Lennox system? Our technicians are factory-familiar with Lennox equipment — we work on XC25, XC21, XP21, EL18XCV and the rest of the Signature Collection, Elite Series, Merit Series lineup on a daily basis. Lennox systems require dealer-specific parts in many cases. Variable-speed repairs are complex and require specialized training.
For duct cleaning work specifically on Lennox, the playbook is different than for a generic system. Lennox runs proprietary control boards, communicating thermostats, and sometimes brand-specific TXV valves and refrigerant charge specs. We carry the brand-specific parts catalog access and the diagnostic software (where applicable) to do the work correctly.
Lennox duct cleaning typically runs $385–$695 in South Bay. Premium-tier brands like Trane and Lennox can run slightly higher on parts, but our labor rate is the same regardless of brand. We always quote up-front and never charge overtime.
10-year parts warranty. Up to lifetime compressor warranty on select units. If your Lennox system is still under warranty, we handle the OEM parts sourcing through Lennox's distributor channel and submit the warranty claim on your behalf — you pay only labor.
When we run duct cleaning on Lennox systems, the issues we find most often are:
Innovation never felt so good — and we honor that with our service. Every technician we send for Lennox duct cleaning has had factory-specific training on Lennox equipment. We use factory certified parts (preferring OEM Lennox parts where available) and document the work with a written report including the readings, the parts replaced, and the system performance verification.
Industry-leading 28 SEER2 on XC25. Solar-ready options available. Maintaining that efficiency over the system's lifespan requires the kind of regular tune-up work most homeowners skip — and most general HVAC shops don't do correctly on premium Lennox equipment.
Verified reviews from South Bay customers with Lennox systems.
“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.”
