Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable HVAC Cleaning Across Windsor
HVAC cleaning in Windsor, CT typically runs $340-$680 for a full system clean on a standard ranch or split-level, and most jobs take four to six hours from panel-off to photo record. If you’re researching what it actually costs and what gets done, you’re already ahead of most homeowners. We’re CleanRun Air Duct Cleaning, and we work in Windsor every week. Call (806) 606-6902 for a written price before any work starts.
Windsor is different from neighboring towns, and your HVAC system knows it. The houses here, the soil under them, the humidity from two rivers, and the age of the ductwork all shape what we find when we open a system. A generic cleaning outfit treats Windsor like any other map pin. We don’t, because the camera doesn’t lie: the inside of a Windsor duct run tells a very specific story, and it’s rarely the same story you’d get in Farmington or East Hartford.
Why CleanRun Air Duct Cleaning Is Windsor’s Preferred HVAC Cleaning Company
We’ve been cleaning and repairing ductwork since 2013, serving over 52,000 homes across Connecticut. Every job, including every job in Windsor, starts with a written price delivered before a single panel comes off. That’s Haven Standard Clause 1, and it means you’ll never stand in your driveway wondering what the final invoice will say. When our crew rolls into the Poquonock area or Windsor Center, the price is already on paper.
Our technicians are background-checked, uniformed, and identified by name before arrival, per Haven Standard Clause 3: Verified Crews. The work ends with a Documented Photo Record of every duct run, inside and out, before and after. You see what we saw. Not a summary, not a vague “looks better now.” The actual interior of your plenum and ducts, photographed and delivered to you as a standard job record. That practice has been in place since our first job.
Windsor homeowners frequently come to us after getting a second opinion. We offer a Free Second Opinion on any written estimate: bring a competitor’s quote, and we’ll put our number next to it in writing. No games. If our number is higher, you’ll see exactly why in the scope of work. And every job carries the 365-Day Done Right Promise: if the work isn’t right, we make it right, in writing, without asking a manager for permission.
Our HVAC Cleaning Services in Windsor

Evaporator Coil Cleaning
In Windsor, the evaporator coil is ground zero for the town’s moisture problem. The coil sits inside the air handler, cold and wet by design, and with river-bottom humidity pressing into basements across town, it rarely dries completely. A 50-year-old system with a clogged coil runs longer to hit the thermostat setting, costing you money every month and pumping damp, stale air through the house. We clean the coil with professional-grade equipment from Rotobrush and treat it with antimicrobial coil treatment to slow regrowth. This is not a wipedown. It’s a deep clean with before-and-after photographs.

Air Handler Cleaning
The air handler in most Windsor homes, especially the 1960s and 70s split-levels along the Farmington River corridor, has been running for decades without the blower wheel and housing being opened. We find dust caked on the blower fins, debris blocking airflow, and often mold growing on the interior housing where condensation collects. A dirty blower wheel moves 30-40% less air in some cases, forcing the system to work harder. We open the air handler, clean the blower, the housing, and the drain pan, then photograph the results.

Condenser Cleaning
The outdoor condenser handles the heat rejection side of your system. In Windsor, cottonwood from the riverbanks, grass clippings from those broad Poquonock lawns, and pollen from the town’s mature tree canopy all build up on the coil fins. A dirty condenser raises head pressure, shortens compressor life, and drives up summer electric bills. We clean the condenser coil, straighten bent fins, and clear the area around the unit. It’s simple work, but it’s work that most Windsor homeowners never think about until the system fails on a 90-degree July day.

Coil Treatment
Cleaning is mechanical: we remove the buildup. Treatment is chemical: we apply an EPA-registered antimicrobial to the evaporator coil and surrounding surfaces to slow the regrowth of mold and bacteria. In Windsor, where the tobacco-soil basements feed moisture into forced-air systems, coil treatment is not an upsell. It’s the difference between a clean system that stays clean and a clean system that reseeds itself within six months. We include coil treatment as a standard part of our evaporator coil cleaning service for Windsor homes, because we’ve seen too many systems go biological again within weeks.

Same photo record.
Common HVAC Cleaning Problems We See in Windsor Homes

- Collapsed flex-duct connectors. On a 1968 ranch in the Poquonock area, our crew found flex-duct connectors collapsed at the trunk, which meant two supply branches had been pulling unfiltered crawlspace air into the bedrooms for years. The fix required sealing the runs and cleaning the evaporator coil, not just running a vacuum through the ductwork.
- Mold reservoirs in basement duct runs. Seasonal flooding and high water tables along the Connecticut and Farmington River corridors introduce moisture into basement ducts and crawlspace plenums. That moisture becomes a persistent mold reservoir, and a cleaning that skips this area just stirs the spores around.
- Degraded fiberglass duct liners. Windsor’s primary suburban buildout from the 1950s through the 1970s left a large inventory of homes with original trunk-and-branch sheet metal ducts lined with fiberglass insulation. After 50-60 years, that liner breaks down and blows fibers into living spaces while trapping dust and mold.
- Biological growth seeding on evaporator coils. The combination of river-bottom humidity and organically rich soil under Windsor’s tobacco-farm subdivisions means basement air carries spores into the system. If the evaporator coil is not treated after cleaning, the growth reseeds within weeks in many Windsor homes.
Pricing for HVAC Cleaning in Windsor, CT
Here are honest ranges for Windsor, in writing. A full HVAC cleaning with evaporator coil, blower, and air handler work on a standard ranch or split-level typically runs $340-$680. If the job requires duct sealing, which is common in Windsor’s older housing stock, that adds $500-$1,400 depending on the number of runs and the extent of the separation. Coil treatment alone runs $95-$175 and is included with evaporator coil cleaning on most full-system jobs. Homes with degrading fiberglass liners may need liner removal or full duct replacement, which is priced per run after camera inspection.
What affects your price: the age of the system, whether the flex-connectors have collapsed, whether there’s mold in the plenum, and how accessible your ductwork is. We deliver a written price before work begins. No per-vent pricing, no bait prices, no van-side surprises.

FAQs - HVAC Cleaning in Windsor

Windsor’s position at the confluence of the Connecticut and Farmington Rivers creates a persistently humid microclimate that accelerates mold growth inside ductwork faster than in inland towns like Bloomfield or East Granby. We regularly find mold reservoirs in basement duct runs and crawlspace plenums in Windsor homes, driven by seasonal flooding and high water tables. A cleaning that doesn’t address this moisture source, and doesn’t treat the coils afterward, means the growth returns quickly. Call (806) 606-6902 to schedule a camera inspection.
Most 1960s ranch homes in Windsor were built with flex-duct connectors joining branch runs to the trunk line. After 50-60 years in damp basements, those connectors collapse or separate, so entire supply branches stop pulling conditioned air from the furnace and instead suck dirty crawlspace air into the bedrooms. Cleaning the ducts without repairing the connections leaves the system immediately re-contaminating itself. We find this on a significant share of the cleaning jobs we do in Windsor’s ranch neighborhoods, and we quote sealing work separately after camera documentation. Call (806) 606-6902 for a written price.
A camera inspection inside a 50-year-old Windsor duct system typically reveals layers of dust and debris, degrading fiberglass liner, biological growth in the plenum, and often the collapsed or separated flex-connectors described above. We photograph everything before and after, and you receive the full photo record as part of your job file. You’ll see the debris, the damage, and the result, in images, not in words. Call (806) 606-6902 to book an inspection and get a written scope of work.
Because much of Windsor’s residential land sits on converted shade-grown tobacco farmland, the soil is organically rich and moisture-retentive, which pushes basement humidity into forced-air systems and accelerates biological growth on the air handler and coil. We recommend Windsor homeowners have the air handler inspected every two to three years, and cleaned whenever the camera shows buildup beyond surface dust. Homes with documented mold or musty odors should not wait. Call (806) 606-6902 for a free estimate.
In most cases, yes, but only if the source of the smell is inside the system and the moisture feeding it is addressed. We clean the coil, blower, and duct runs, then treat the coil surfaces with antimicrobial treatment to kill the biological growth causing the odor. If the smell persists, the source is usually a foundation leak or standing water in a crawlspace, which we’ll document and flag for you. We won’t sell you a treatment that won’t solve the problem. Call (806) 606-6902 and we’ll start with the camera.
