Fast, Reliable Air Duct Cleaning Across Old Greenwich
Air duct cleaning in Old Greenwich, Connecticut typically costs $380-$780 for a full residential system, with most jobs completed in a single visit. Bellows Air Duct & Vent Co. has served coastal Fairfield County homeowners for over 42 years, and we know the salt-laden humidity off Long Island Sound creates ductwork problems you won’t find inland. Call (844) 685-6342 for a free estimate with upfront pricing.
We answer our phones live, 24 hours a day. Our background-checked, uniformed technicians arrive on time to homes from Shore Road to Sound Beach Avenue, from the village center out to Greenwich Point. We don’t use bait coupons or surprise charges. The price we quote is the price on the invoice.
Old Greenwich’s housing stock sets it apart. The 1920s-1950s colonials, cape cods, and converted summer cottages that fill this ZIP code 06870 neighborhood were often retrofitted with forced-air HVAC decades after construction, leaving tight, irregular duct runs threaded through original framing. Some shoreline estates still run on galvanized sheet-metal ductwork that’s accumulated decades of debris and oxidation from salty coastal air. That legacy infrastructure demands a technician who recognizes corrosion patterns before they become failures.
Why Bellows Air Duct & Vent Co. Is Old Greenwich’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Old Greenwich on showing up when we say we will and standing behind the work. Our 90-Day Done Right Promise is stamped on every job: if something isn’t right, we return at no charge with no paperwork required. No arguing. We’ve honored that promise since 1984.
Our Air Duct Cleaning team uses camera inspection before and after every clean, so you see what we see inside your ducts. That visual record matters in Old Greenwich, where salt-air damage can hide inside metal runs that look fine from the outside. We recently serviced a 1930s colonial on Shore Road where the owner noticed a musty smell. Our video inspection revealed heavy oxidation inside the galvanized sheet-metal ductwork and mold colonization in the return plenum, a direct consequence of salt air drawn in from Long Island Sound. We performed a full system cleaning with Rotobrush equipment and applied an antimicrobial coating, eliminating the odor and restoring airflow.
Calls are answered by a live person, not voicemail, not an app. Most jobs finish in one visit. Our technicians are background-checked and uniformed, and they carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same brands serious HVAC contractors specify.
We offer a permanent 5% Senior and Veteran discount, plus $50 off any repair over $250, a free second opinion on any written estimate, and our $89 seasonal tune-up. Upfront pricing is disclosed before a single tool is lifted.
Our Air Duct Cleaning Services in Old Greenwich
Residential Duct Cleaning
Old Greenwich homes present specific challenges: retrofitted systems in converted summer cottages, legacy galvanized ductwork near the Sound Beach shoreline, and flex-duct liners degraded by salt air. Our residential cleaning addresses the full supply and return network, including trunk lines, branch ducts, and registers. We camera-inspect first, then clean with Rotobrush contact vacuuming and compressed-air whipping tools that dislodge buildup without damaging aged components. A typical residential duct cleaning in Old Greenwich runs $380-$620 for a single-system home.

Commercial Duct Cleaning
Commercial properties in Old Greenwich’s village center and along Sound Beach Avenue, including restaurants, retail spaces, and professional offices, require scheduled maintenance that doesn’t disrupt business hours. We work evenings and weekends when needed, cleaning rooftop units, exhaust systems, and distribution ductwork. Commercial pricing starts around $680 and scales with system complexity. All work is camera-documented for property management records.

Supply Duct Cleaning
Supply ducts deliver conditioned air to your rooms. In Old Greenwich, these lines often show the first visible damage from salt-air infiltration: rust-staining at registers, flaking metal debris, and restricted airflow from particulate buildup. We clean each supply branch individually, seal accessible leaks, and note any corrosion that warrants repair or replacement. Supply-only cleaning in Old Greenwich typically runs $280-$480.

Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and they’re where moisture and mold colonies concentrate in humid coastal homes. In Old Greenwich properties with unlined metal returns, we’ve found mold colonization severe enough to trigger respiratory complaints. Our return duct cleaning includes the return plenum, filter rack, and main trunk, with antimicrobial treatment applied where biological growth is present. Return-only service ranges $320-$520.

Video Inspection
Every Bellows job includes before-and-after camera documentation. In Old Greenwich, this isn’t optional, it’s diagnostic. Salt-air corrosion, flex-duct liner separation, and mold colonization aren’t visible from registers. Our video inspection identifies problems that justify cleaning, documents the results, and flags legacy ductwork nearing replacement. Standalone video inspection for system assessment runs $180-$280.

Full System Cleaning
Our most thorough service: supply ducts, return ducts, trunk lines, plenums, registers, grilles, and the HVAC cabinet itself. For Old Greenwich homes with decades of accumulated salt-particulate buildup and oxidation products, full system cleaning restores airflow and indoor air quality in one visit. Typical range: $580-$780. We recommend this for first-time cleaning of older homes and for properties within three blocks of the Sound Beach shoreline.

Common Air Duct Cleaning Problems We See in Old Greenwich Homes
- Salt-air corrosion in legacy galvanized ductwork. Homes near Greenwich Point and the Sound Beach shoreline frequently contain decades-old galvanized sheet-metal ducts that have oxidized from the inside out. The flaking metal debris contaminates supply air and degrades indoor air quality. Camera inspection reveals the extent before cleaning begins.
- Mold colonization in unlined metal ducts. High humidity near Long Island Sound keeps duct surfaces damp long enough for mold to establish colonies, especially in older homes with tight, retrofitted runs that trap condensation. We treat affected surfaces with antimicrobial coating after cleaning.
- Premature flex-duct liner deterioration. Salt particulates drawn through coastal homes accelerate breakdown of flex-duct inner liners, causing hidden leaks and energy loss. Improper DIY cleaning or too-long intervals worsen the problem. Our technicians identify liner damage during inspection and recommend repair or replacement.
- Restricted airflow from accumulated debris. Older homes with irregular duct runs and 90-degree turns trap dust, pollen, and salt residue more readily than modern systems. This forces HVAC equipment to work harder, raising energy bills and shortening component life.

FAQs - Air Duct Cleaning in Old Greenwich
Homes near Long Island Sound typically need duct cleaning every 2-3 years, not the 3-5 year interval standard for inland Fairfield County. Salt-laden humidity accelerates corrosion and mold colonization inside ductwork, especially in legacy galvanized systems. If you live within a few blocks of the Sound Beach shoreline or Greenwich Point, we recommend inspection every 18-24 months. Call (844) 685-6342 to schedule a free assessment.
Rust-staining around supply registers, musty odors when the system runs, reduced airflow from room to room, and visible corrosion on accessible metal components all indicate salt-air damage. In Old Greenwich, these symptoms appear earlier and more severely than inland. If you notice any of these, a video inspection will show the full extent. Call (844) 685-6342 for a free estimate.
Yes. We’ve cleaned ductwork in dozens of Old Greenwich converted cottages where forced-air was retrofitted through original framing. Our Rotobrush and compressed-air tools navigate tight spaces without damaging aged components. Camera inspection first lets us map the system and identify any runs too compromised to clean safely. Most of these jobs finish in one visit. Call (844) 685-6342 to discuss your specific layout.
We apply an EPA-registered antimicrobial coating to treated surfaces, which inhibits mold regrowth. We also identify and seal accessible air leaks that draw in unconditioned, humid outside air. In Old Greenwich’s coastal environment, we recommend maintaining indoor humidity below 55% and scheduling inspection every 2-3 years. Call (844) 685-6342 for specific guidance on your home.
Yes. Central AC in Old Greenwich circulates humid, salt-carrying air continuously during summer months, compounding the biological-growth risk inside ductwork. The same corrosion and mold problems occur in cooling-only systems. In fact, the condensation from air conditioning can make mold colonization more likely than in heating-only systems. A typical AC-only duct cleaning in Old Greenwich runs $380-$620. Call (844) 685-6342 for a free estimate.
