Lennox Air Duct Cleaning in Boulder, CO
We provide independent Lennox service across Boulder, and we’re not affiliated with the manufacturer. What sets our Lennox work here apart is that we treat the duct system and the equipment as one problem: the blower, the coil, the return grilles, and the ductwork all get diagnosed together. Our technicians have up to 10 years of experience with Lennox air handlers, furnaces, and ducted systems. Call (866) 361-9658 for a free estimate.
Key Takeaways

- Contact-and-capture cleaning with Rotobrush brush agitation and Nikro HEPA extraction.
- Return duct cleaning, duct sealing, and evaporator coil cleaning under one visit.
- Free estimate, one flat price per system agreed before work starts.
- Before-and-after photos of your own ducts so you can see the result.
Why Boulder Residents Choose Us for Lennox Service
We know Lennox equipment from the inside out. The brand’s residential and light-commercial air handlers, furnaces, and ducted systems each have their own airflow quirks, and we’ve worked on enough of them to recognize the signs early. When a Merit Series furnace starts short-cycling or an Elite Series air handler throws a pressure-switch fault, we know where to look first.
That matters more in Boulder than in most places. The housing stock ranges from 1900s bungalows to post-war ranches to newer east-side builds, and each one moves air differently. We bring contractor-grade gear to every job: Rotobrush brush-agitation systems paired with Nikro HEPA-vacuum extraction, plus Abatement Technologies air-filtration equipment when the job calls for it. We also supply and install Honeywell and Aprilaire filtration and IAQ products, so you can move from clean ducts to better filtration in the same visit.
We’re an independent shop. We repair, install, and service Lennox equipment with quality parts that fit it – including OEM components for critical parts like blower motors, control boards, and heat exchangers. We’re licensed and insured, and we give you a written estimate before any work begins.

Common Lennox Air Duct Cleaning Problems We Solve in Boulder
- Merit Series blower wheels caked with lint. In older Boulder bungalows, these PSC blower motors often run at low static pressure. Dust and cottonwood fluff slip past undersized filters and coat the blower wheel, which cuts airflow and leaves rooms hot and cold in the same house.
- Elite Series pressure-switch faults. Variable-speed air handlers are sensitive to restricted returns. Boulder’s dry, high-elevation winters make the air static-prone, so lint hangs longer and clogs secondary heat exchanger fins. The result is a fault code that looks electrical but is actually a duct problem.
- Leaking sheet-metal joints in Mapleton Hill and Whittier homes. Signature Collection systems connected to original ductwork pull attic dust and spring pollen through every leaky joint. That debris lands on the evaporator coil and blower, and airflow drops.
- Clogged Healthy Climate humidifier and HRV/ERV cores. Late-May cottonwood seed and grit pack into bypass humidifiers and ventilation cores, forcing the blower to work harder and spreading debris through the supply runs.
- Return grilles packed in a single weekend. During cottonwood season, return-air grilles and intake screens can fill up fast. When they do, blower strain goes up and delivered airflow goes down across the whole system.
Lennox Service in Boulder: What Local Conditions Mean for Your Equipment
Boulder’s late-May cottonwood-seed season along Boulder Creek and the Skunk Creek greenbelt doesn’t just make a mess outdoors. It clogs Lennox return-air grilles and intake screens, sometimes in a single weekend. Add the persistent upslope wind funneling off the Flatirons, and fine dust and pollen get pushed into returns faster here than in neighboring Front Range towns. Then there’s the housing: many east-side homes still run original 1950s gravity furnace ducting connected to a newer Lennox furnace, and that older ductwork leaks at every joint. So Lennox duct cleaning in Boulder is rarely just scrubbing a big system. It usually combines aggressive return cleaning with joint sealing, because the ductwork itself is the weak point. What a typical job looks like: a technician finds the return grille packed with seed fluff, the blower wheel coated in lint, and leaky joints pulling attic dust into the airstream. The fix is cleaning the return and supply runs, sealing accessible joints with mastic, and cleaning the blower and evaporator coil to restore airflow.

AfterLennox Service Pricing in Boulder
Pricing depends on the size and condition of your system, how many returns need cleaning, whether duct sealing is required, and whether the evaporator coil or blower needs attention. We don’t quote per-vent prices. You get one flat price per system, agreed before any work starts, and the written estimate sets the final price. Your free estimate includes a walkthrough of the duct system, an airflow check at the returns, and a clear explanation of what needs cleaning versus what needs sealing or repair. For a home with original sheet-metal ductwork, expect the sealing portion to make up a real share of the work. Call (866) 361-9658 for an exact quote – estimates are free.
