Why Bellows Air Duct & Vent Co. Is Lafayette’s Preferred HVAC Cleaning Company
We’ve built our reputation in Lafayette one appointment at a time, and a lot of those appointments start with homeowners who’ve already been burned by a low-bid operator. Our 90-Day Done Right Promise is stamped on every job in writing: if the work isn’t right, we return at no charge with no paperwork required. That’s not marketing language, it’s how we’ve operated since 1984.
Our technicians are background-checked, uniformed, and equipped with professional-grade Rotobrush and Nikro equipment. Calls are answered by a live person 24 hours a day, not a voicemail tree. Most Lafayette jobs are completed in a single visit because we ask the right questions before we arrive, how many returns, how old’s the system, any detached buildings with ductwork, any agricultural dust issues you’ve noticed. That preparation matters on acreage properties where a return trip costs everyone time and fuel.
We also offer a permanent 5% Senior and Veteran discount, a $89 Seasonal Tune-Up, and free second opinions on any written estimate you’ve received. Our pricing is disclosed upfront before a single tool is lifted, so the number on the phone is the number on the invoice.
Our HVAC Cleaning Services in Lafayette
Evaporator Coil Cleaning
The evaporator coil in your Lafayette home works harder than it would at sea level. At roughly 5,200 feet with frequent Chinook winds driving dust through every gap in the envelope, that coil cakes with debris faster than manufacturers’ standard maintenance intervals suggest. We remove the coil assembly when accessible, clean with foaming treatment and low-pressure rinse, and verify airflow improvement with before-and-after camera documentation. For homes near the eastern farmland, this service is particularly critical, the fine reddish-tan agricultural dust that blows in during spring planting and fall harvest seasons packs onto wet coil surfaces and hardens into a thermal blanket that forces your compressor to run longer and louder.
Blower Cleaning
A dirty blower wheel doesn’t just move less air, it moves air unevenly, creating hot and cold spots through your Lafayette home. We disassemble the blower housing, clean the wheel vanes and motor housing, and inspect the capacitor and bearings while we’re in there. In older Lafayette homes near Simpson Street with original sheet-metal trunk lines, blower imbalance is often the real culprit behind “the system just doesn’t breathe like it used to.” One cleaning usually restores the cubic feet per minute the system was designed to deliver.
Condenser Cleaning
Your outdoor condenser in Lafayette faces a unique assault: agricultural dust from the east, cottonwood fluff in late spring, and the fine grit that Chinook winds strip from the Front Range foothills. We pull the fan assembly, straighten damaged fins, and deep-clean the coil with foaming agent and low-pressure water, never the high-pressure washer that folds fins flat and destroys capacity. For acreage properties with condensers exposed to full wind fetch across open land, we recommend annual cleaning rather than the biennial schedule that might suffice in more sheltered Boulder neighborhoods.
Air Handler Cleaning
The air handler is where your conditioned air gets its final push into the ductwork, and in Lafayette’s climate, it’s also where temperature differentials create condensation that mixes with dust into a paste. We clean the entire air handler cabinet, including the drain pan and condensate line, and treat with an EPA-registered antimicrobial where moisture staining indicates biological growth. For homes with crawl-space foundations, common throughout Lafayette, we pay particular attention to rodent intrusion pathways into return-air chases, a recurring finding in this market that technicians from flatter, drier climates often miss.

Trusted Brands We Service in Lafayette
We maintain professional-grade equipment from Nikro, Honeywell, and Aprilaire, the same brands serious HVAC contractors specify for their own installations. For Lafayette customers, this means we stock common replacement components locally rather than ordering from a warehouse three days out. When your Aprilaire media cabinet needs a new filter frame or your Honeywell electronic air cleaner requires cell cleaning, we handle it during the same visit rather than scheduling a follow-up that leaves you breathing dirty air for another week.
Common HVAC Cleaning Problems We See in Lafayette Homes
- Agricultural dust overload. The fine reddish-tan dust that blows in from Boulder County farmland during spring planting and fall harvest loads return-air plenums faster than typical suburban dust. Homeowners in Lafayette’s eastern subdivisions often notice reduced airflow within 18 months of a standard cleaning cycle.
- Original ductwork in historic homes. The 1920s-1950s bungalows and craftsman homes near Simpson Street frequently retain original sheet-metal trunk lines with decades of accumulated debris, plus joints that have loosened through thermal cycling. Cleaning without inspecting for separations can actually worsen leakage.
- Crawl-space flex-duct deterioration. Lafayette’s common crawl-space foundations expose flex duct to rodent activity, moisture, and the weight of settled insulation. We regularly find disconnected returns pulling air from the crawl space rather than the conditioned rooms above.
- Post-Marshall Fire residual contamination. Homes that sheltered in place during the December 2021 fire or were exposed to smoke saturation afterward still show elevated particulate levels in HVAC systems. Standard cleaning protocols don’t address the ultrafine ash and combustion byproducts that settled in ductwork during that event.
Pricing for HVAC Cleaning in Lafayette, CO
A typical residential HVAC cleaning in Lafayette runs $180-$280 for a single-system home with standard access, $320-$450 for larger homes with multiple air handlers or detached workshop ductwork.

Air handler cleaning, which includes drain pan and condensate line service, runs $150-$220 depending on accessibility.
What moves you up or down in those ranges: system age and condition, number of returns and supplies, crawl-space or attic access difficulty, presence of the agricultural dust that requires extended vacuum time, and whether we’re also addressing post-wildfire residual contamination. We disclose the full price before work begins, every time. No bait coupons, no price changes at the door. Call (844) 685-6342 for an exact quote, estimates are free.

FAQs - HVAC Cleaning in Lafayette
Most Lafayette homeowners east of Public Road need cleaning every 18-24 months rather than the typical 3-5 year interval. The fine reddish-tan agricultural dust that blows in from surrounding farmland during spring planting and fall harvest is lighter and more penetrating than standard household dust, and it loads filters and duct surfaces faster than in more urbanized neighbors like Boulder. If you can see a film on your return grilles within two months of replacement, you’re likely on the accelerated schedule. Call (844) 685-6342 and we’ll assess your actual loading rate, estimates are free.
We clean ductwork and HVAC components in detached workshops with the same thoroughness as your main residence, though we need to know about the building when you call so we schedule adequate time. We serviced an acreage property off Oxford Road where the homeowner’s detached workshop had a heavy-duty ¾-horsepower LiftMaster opener struggling with a sagging 16×10-foot insulated door. Our team cleaned the 20-year-old Rotobrush-evacuated return plenum, removed the characteristic agricultural dust, and lubricated the torsion springs, all in one trip to avoid a second drive. Tell us about any outbuildings when you book, and we’ll bring the right equipment and time allocation.
Yes. The historic homes near Simpson Street often retain original sheet-metal trunk lines from the 1920s-1950s that have never been properly cleaned and may have separated at joints due to decades of thermal expansion. We camera-inspect before any aggressive cleaning to avoid pushing debris into hidden separations or worsening existing leakage. The metal itself is usually sound, but the connections and any later-added flex duct need careful evaluation. We’ve restored airflow in these homes without replacing the original trunkwork, which preserves the character and saves significant expense.
Yes, and this is a specific area of concern for Lafayette that cities farther from the fire corridor simply do not share. The Marshall Fire of December 2021 drove severe wildfire smoke and ash infiltration into HVAC and duct systems across Lafayette, even in homes that were not directly threatened. Standard cleaning removes bulk debris but does not address the ultrafine combustion particulate and ash residue that settled in ductwork and continues to recirculate. We use enhanced HEPA evacuation and multiple-pass cleaning protocols for these systems, with camera documentation showing before-and-after particulate levels. If your home was occupied or returned to during the smoke event, mention it when you call so we allocate the extended time these jobs require.
You don’t necessarily need it every time, but in Lafayette’s semi-arid, high-particulate environment, the coil is usually the dirtiest component we find. The combination of agricultural dust, altitude-driven lower air density, and frequent cycling between heating and cooling seasons creates ideal conditions for rapid coil fouling. A dirty coil can reduce system efficiency by 20% or more and cause liquid refrigerant to flood back to the compressor, shortening its life. We inspect with a borescope and show you the actual condition before recommending the service, no scare tactics, just the image and our recommendation. The $95-$140 cost is typically recovered in the first season through reduced energy use.
