Full HVAC cleaning in Greenwich, NY typically runs $340-$780 for most homes and is completed in a single visit, with back-country estates requiring full-day or multi-day crews.

Call us at (833) 348-8789 for a free estimate, or read on to see how we handle the specific challenges of your home.
Greenwich isn’t a standard suburban market. The village homes off Putnam Avenue and around Cos Cob were built before ducted HVAC existed, and the back-country estates off Round Hill Road and North Street operate at a scale most duct cleaners have never encountered. We’ve learned that the hard way, and we’ve built our HVAC Cleaning team and equipment around what actually shows up in Greenwich driveways.
Why Bellows Air Duct & Vent Co. of New York Is Greenwich’s Preferred HVAC Cleaning Company
We’ve been serving Fairfield County homeowners for over 42 years, and Greenwich has always been a distinct market for us - not because of the price point, but because of the complexity. Our technicians know the difference between a 1780s Colonial on Milbank Avenue with retrofit ductwork squeezed through original floor joists, and a 2005 estate on Clapboard Ridge Road with six air handlers and a pool house tied into the main system. That local knowledge prevents the under-scoping that wastes a homeowner’s day.
Our reviews from Greenwich customers consistently mention two things: we show up when we say we will, and the price on the phone matches the price on the invoice. No bait coupons, no upsells at the door. Our 90-Day Done Right Promise applies to every job in Greenwich - if it’s not right, we return at no charge, no paperwork required.
Calls are answered by a live person, 24 hours a day. Not a voicemail tree, not an app. If you’re calling from a back-country estate at 7 a.m. before the household staff arrives, or from a village home after noticing musty airflow, you’ll reach someone who can dispatch a crew and give you an honest timeframe.
Our HVAC Cleaning Services in Greenwich
Evaporator Coil Cleaning
Evaporator coils in Greenwich homes work harder than most. The coastal humidity off Long Island Sound keeps indoor moisture levels elevated, especially in finished basements and wine cellars common in older village properties. Dirty coils freeze up, restrict airflow, and drive energy bills upward. We remove the coil assembly when accessible, clean with foaming agent and low-pressure rinse, and verify with camera inspection before reassembly. In Greenwich’s humid conditions, we recommend annual coil inspection as part of our $89 Seasonal Tune-Up.
Blower Cleaning
The blower motor and housing collect dust and debris that strain the entire system. In Greenwich’s historic homes with retrofit ductwork, blowers often run at higher RPMs to overcome restricted airflow through non-standard routing, accelerating wear. We remove the blower assembly, clean the squirrel cage and housing, lubricate bearings, and test amperage draw. Most blower cleanings in Greenwich homes are completed in two to three hours.
Condenser Cleaning
Outdoor condenser units in Greenwich face salt air exposure from Long Island Sound, plus pollen and leaf debris from the mature oak and maple canopy throughout town. We clean condenser fins with foaming cleaner and low-pressure water, straighten damaged fins, and check refrigerant levels. For waterfront homes along Indian Harbor or Greenwich Cove, we pay particular attention to salt corrosion on electrical connections.
Air Handler Cleaning
Air handler cleaning is where Greenwich’s estate market demands our full attention. On a 15,000 sq ft back-country estate off Round Hill Road, we cleaned a multi-zone system where the homeowner was unaware of a secondary air handler in the staff quarters. Our Rotobrush equipment navigated sagging flex-duct runs in the attic, and we treated a coil with Guardsman antimicrobial to address mold from coastal humidity. We always conduct a full system walk-through before quoting in Greenwich - missing a secondary unit means an incomplete job and an unhappy homeowner.
Heat Exchanger Cleaning
Heat exchanger cleaning requires camera inspection and, when indicated, mechanical brushing. In Greenwich’s older village homes with original oil-to-gas conversions, heat exchangers may have decades of soot accumulation or corrosion from prior fuel types. We document condition with before-and-after video, and we’ll show you exactly what we found. Safety note: cracked heat exchangers can leak carbon monoxide. If we find damage, we flag it immediately and recommend qualified repair before operation continues.
Coil Treatment
After cleaning, we apply antimicrobial coil treatment to inhibit mold and bacterial growth. In Greenwich’s humid waterfront environment, this step is particularly valuable. We use Guardsman and Aprilaire treatments, selected for the specific coil material and contamination type. Treatment adds $85-$140 to a standard coil cleaning, and we recommend it for any home where we’ve found moisture infiltration or visible microbial growth.

Trusted Brands We Service in Greenwich
We clean and service equipment from Honeywell, Aprilaire, Abatement Technologies, and Guardsman - the same brands serious HVAC contractors specify for high-end installations. We stock common replacement parts and treatment supplies locally, so most Greenwich jobs don’t wait on shipping. For estate homes with proprietary or imported equipment, we source through our network and coordinate with your existing HVAC contractor when appropriate. The goal is one visit, done right, with no return trip for a part we didn’t have.
Common HVAC Cleaning Problems We See in Greenwich Homes
- Missed secondary air handlers in multi-building estates. Pool houses, carriage houses, and staff quarters often tie into the main system through duct branches the homeowner has never inspected. We find these during our initial walk-through, but many competitors don’t look, leading to incomplete cleaning and callbacks.
- Sagging flex-duct in back-country attics. The 1990s-2000s estate builds used extensive flex-duct that degrades and sags at low points, trapping debris where standard equipment can’t reach. Our truck-mount systems and extended-reach tools handle runs up to 150 feet.
- Moisture infiltration in historic basement and wine cellar ductwork. Greenwich’s coastal humidity seeps into finished basements and climate-controlled wine cellars, creating conditions for mold that standard dry duct cleaning won’t address. We inspect with borescope cameras and treat affected coils and plenums with antimicrobial agents.
- Under-powered equipment on oversized systems. Standard portable duct cleaners lack the vacuum capacity for 10,000+ sq ft homes with complex zoning. We deploy truck-mount Rotobrush and Nikro systems for Greenwich estate work, sized to the job.

FAQs - HVAC Cleaning in Greenwich
We approach historic homes with extra time built into the schedule and smaller-diameter tools for tight access points. Original 18th- and 19th-century framing in the village and Cos Cob areas often forces non-standard duct routing through spaces never designed for it, so we inspect with borescope cameras before committing to a cleaning path that won’t damage original plaster or trim. Call (833) 348-8789 to schedule a walk-through - estimates are free.
Yes, we apply Guardsman and Aprilaire antimicrobial coil treatments specifically for moisture-related microbial growth. The coastal humidity in Greenwich - higher than inland Fairfield County or Westchester - regularly produces mold and mildew findings in finished basements and wine cellars during our inspections. Treatment runs $85-$140 per coil and is recommended whenever visible growth or musty odor is present.
Yes, and we specifically scope these jobs before quoting to avoid the under-scoping that plagues estate work. Secondary air handlers and duct branches in staff quarters, pool houses, and carriage houses are common enough in back-country Greenwich that our technicians expect them. We use truck-mount equipment with extended reach for long duct runs, and we schedule full-day or multi-day crews for estates exceeding 10,000 sq ft. Call (833) 348-8789 for estate-specific scheduling.
We use professional-grade Rotobrush and Nikro duct cleaning systems, plus Abatement Technologies HEPA filtration for containment. For coil treatment, we apply Guardsman and Aprilaire antimicrobials. These are the same brands specified by serious HVAC contractors, not discount operators. Our truck-mount systems handle the long duct runs and high air volumes common in Greenwich estate homes.
A back-country estate in ZIP 06831 typically requires a full day or multiple days, depending on square footage and system complexity. A 10,000-15,000 sq ft home with four to six zones usually takes one full day; estates exceeding 20,000 sq ft or with multi-building HVAC ties may need two days. We never rush estate work - the Done Right Promise applies, and a callback on a job this size costs everyone more time. Call (833) 348-8789 to discuss your property’s specific scope.
We’re Bellows Air Duct & Vent Co., and we’ve been driving to Greenwich since 1984.
