We’re on Broadway, Water Street, and Tower Parkway regularly, and we aim to be at your door same day or next when you call (844) 685-6342.

Why Bellows Air Duct & Vent Co. Is New Haven’s Preferred HVAC Cleaning Company
We’ve built our reputation in New Haven one job at a time, mostly by word of mouth from homeowners who’ve lived in the same house for twenty or thirty years and don’t want to explain their ductwork twice. Our technicians are background-checked, uniformed, and trained on the specific problems New Haven’s housing stock creates - not generic suburban systems. Calls to our office are answered by a live person, 24 hours a day, not a voicemail tree or an app. That matters when you’re calling about mold in your registers or a system that won’t keep up during a humid August on Long Island Sound.
Our 90-Day Done Right Promise applies to every New Haven job. If something isn’t right, we come back at no charge. No paperwork to file, no argument. We’ve operated this way for over 14 years, and it’s why customers from Mill River to Pine Rock call us back.
Our HVAC Cleaning Services in New Haven
New Haven’s forced-air systems weren’t born in the houses they now occupy. They were retrofitted into triple-deckers, two-families, and converted mansions that originally ran on steam or hot water. That history changes how we approach every sub-service.
Evaporator Coil Cleaning
The evaporator coil in a New Haven retrofit is often crammed into a closet or former pantry that was never meant to house HVAC equipment. Coastal humidity from New Haven Harbor keeps these coils wet longer than inland systems, and the microbial growth we find on coils in Fair Haven and East Shore isn’t ordinary dust - it’s biofilm fed by persistent maritime moisture. We clean with foaming agents and low-pressure rinses that won’t damage aged aluminum fins, then document the before and after with our camera system. A typical evaporator coil cleaning in New Haven runs $180-$320.
Air Handler Cleaning
Air handlers in New Haven’s older buildings sit in basement corners, attic kneewalls, or spaces carved out of former coal bins. They’re rarely on level pads, and the return plenums are often cobbled together from multiple eras of repair. We disassemble and clean blower wheels, housings, and filter racks, checking for the salt-corrosion patterns that show up in coastal neighborhoods. Our crew carries replacement hardware for the non-standard connections we encounter in pre-war buildings. Air handler cleaning in New Haven typically costs $240-$420.
Blower Cleaning
A dirty blower wheel in a New Haven triple-decker doesn’t just move less air - it works harder against duct systems that were already undersized for the retrofit. We remove the blower assembly, clean the wheel and housing with compressed air and contact-safe solvents, and balance the assembly before reinstalling. In student rentals around Dwight and Dixwell, we often find blowers caked with years of accumulated debris from skipped maintenance between tenants. Blower cleaning alone runs $150-$260 in the New Haven market.
Condenser Cleaning
New Haven’s condensers battle more than pollen and leaves. The salt air from Long Island Sound accelerates fin corrosion on outdoor units, especially in neighborhoods south of Tower Parkway. We clean coils with foaming agents that lift debris without driving it deeper, straighten damaged fins, and check refrigerant levels. A condenser cleaning in New Haven typically costs $140-$250, with coil treatment add-on available for units showing early corrosion.
Coil Treatment
After cleaning, we apply an EPA-registered coil treatment that inhibits microbial regrowth. In New Haven’s humid climate, this step isn’t optional for many customers - it’s the difference between a clean coil and one that’s fouled again within a season. Coil treatment adds $80-$140 to any cleaning service and carries our standard 90-day guarantee.
Heat Exchanger Cleaning
Furnace heat exchangers in New Haven’s retrofitted systems often show stress cracking from decades of cycling in tight, poorly ventilated spaces. We camera-inspect every heat exchanger before cleaning, and if we find deterioration that affects safety, we stop and explain exactly what we’re seeing. Cleaning runs $200-$350 when the exchanger is sound and accessible.

Trusted Brands We Service in New Haven
We clean and maintain systems built with Aprilaire media filters and humidifiers, Abatement Technologies HEPA equipment, and Rotobrush mechanical cleaning systems - the same brands serious HVAC contractors specify for their own jobs. Our New Haven crew stocks common replacement parts for these manufacturers, so we’re not waiting on shipping when your system needs more than cleaning. That matters in a city where a failed blower on a humid July weekend can make a third-floor apartment unlivable.
Common HVAC Cleaning Problems We See in New Haven Homes
- Skipped maintenance in student rentals. Landlords in neighborhoods like Dwight and Dixwell often skip duct cleaning between tenants, allowing years of dust, mold, and rodent debris to accumulate in inaccessible chases. We pull surprising loads from these systems, and the turnover cycle means the next tenant inherits the problem.
- DIY flex-duct repairs with non-rated materials. Handymen in older multi-families often use flex duct that kinks, restricts airflow, and harbors moisture - especially in high-humidity zones near Long Island Sound. We replace these with properly sized, insulated hard duct where accessible.
- Coastal corrosion mistaken for dust. Salt-laden air in Fair Haven and East Shore causes premature metal-duct failure. Technicians unfamiliar with New Haven’s coastal exposure pattern often mistake rust debris for ordinary dust contamination and miss the underlying structural damage entirely.
- Mold in uninsulated crawl-space runs. The tidal stretches of the Quinnipiac and Mill rivers create basement humidity that mainland Connecticut doesn’t match. Ductwork in these conditions grows mold that looks like black staining on registers and can trigger respiratory complaints.

FAQs - HVAC Cleaning in New Haven
East Shore sits directly on New Haven Harbor with salt-laden air pushed inland by prevailing southerlies, and the tidal Quinnipiac River borders the neighborhood to the west. That combination exposes basement and crawl-space ductwork to chlorides that accelerate galvanic corrosion at seams and joints. We regularly find rust-through in galvanized plenums that inland cities wouldn’t see for another decade. If you’re in East Shore and haven’t had your ducts inspected in recent years, call (844) 685-6342 for a camera look - estimates are free.
Cleaning removes active mold growth and biofilm, but it doesn’t fix the moisture source that allowed it. In New Haven’s triple-deckers, that source is usually uninsulated duct runs in humid basements, leaky crawl-space chases, or condensate drainage problems. We clean, apply EPA-registered biocide, and document the moisture pathway so you or your contractor can address it. For severe cases in Fair Haven and near the Mill River, we often recommend duct sealing or partial replacement after cleaning. Call for an assessment - we’ll show you exactly what the camera sees.
Yes, and it’s rarely done. The high-turnover rental market around Dwight, Dixwell, and Beaver Hills means tenants cycle through every one to two years, and landlords often treat ductwork as out of sight, out of mind. We’ve opened systems with five or more years of accumulated debris from multiple occupants, including pet dander, cooking residue, and rodent activity. For property owners, cleaning between tenants protects your mechanical equipment and reduces complaints. For incoming tenants, it’s a health consideration. We offer straightforward pricing for rental turnovers - call for a quote.
Carefully, and with patience. The forced-air retrofits in New Haven’s 1880-1940 housing used whatever chase was available: former chimney flues, interior walls stripped to studs, closet soffits, and unlined crawl spaces. Our technicians carry specialized access tools for tight spaces and camera systems that let us inspect runs we can’t physically enter. When we find collapsed or disconnected sections - common in Fair Haven retrofits - we explain the repair options before doing anything that opens walls or ceilings. We’ve worked on Water Street triple-deckers and Broadway conversions alike; we know the building types.
We specialize in them. New Haven’s ad-hoc retrofits from the 1960s through 1980s used sheet-metal configurations that don’t match any manufacturer’s standard. Our crew fabricates transitional fittings on site when needed and carries a range of adapters for the oddball connections we encounter. We recently serviced an early-1900s triple-decker on Water Street in Fair Haven where a forced-air retrofit from the 1970s had its main return duct wedged behind a brick chimney in an unlined crawl space. Coastal salt air had eaten through the lower seam of the galvanized plenum, and we found black mold coating the first-floor registers. Our crew sealed the breach, replaced two collapsed sections with 26-gauge ductwork, and applied an EPA-registered biocide to the interior surface. That’s the kind of job we do in New Haven.
