Call (844) 685-6342

We’ve been driving to Greenwich since 2012. Our crews know the difference between a quick coil cleaning on a condo near the Stamford border and a multi-day project up in the back-country, where a single estate might hide eight separate air handlers behind fieldstone walls. We’re familiar with the tight streets of Old Greenwich, the winding drives of 06831, and the particular headaches of downtown colonials where ductwork was shoehorned around original steam systems. When you call Bellows, you get a live person, 24 hours a day, and a technician who shows up in uniform with a camera, a Rotobrush, and the patience to do the job properly.

Why Bellows Air Duct & Vent Co. Is Greenwich’s Preferred HVAC Cleaning Company

Greenwich homeowners have kept us busy for over four decades. They call back because we quote by the air handler on large properties, not by the square foot or by some flat rate that falls apart once we’re inside. Our HVAC Cleaning team has handled everything from a single condenser unit on a Riverside ranch to full estate cleanings on North Street where six separate systems needed individual attention.

We answer our own phones. No app, no voicemail tree, no call center in another state. A live person picks up, 24/7, and schedules you with background-checked, uniformed technicians who arrive when they say they will. Every job gets camera-inspected before and after, so you see what we saw, and what we removed. Our 90-Day Done Right Promise means if something isn’t right, we return at no charge. No paperwork, no arguing. We’ve operated this way since 2012 because it works.

Our pricing is disclosed before we lift a single tool. The number on the phone matches the number on the invoice. We don’t bait with a low coupon and then add charges at the door. For repairs over $250, we offer $50 off. Seniors and veterans receive a permanent 5% discount. And if you have another company’s written estimate, we’ll give you a free second opinion.

Our HVAC Cleaning Services in Greenwich

Evaporator Coil Cleaning

Greenwich’s position on Long Island Sound keeps summer dew points high well into September. That persistent humidity clings to evaporator coils, especially in secondary zones like guest wings and finished basements that may go days without airflow. We remove the coil assembly where accessible, apply foaming cleaner from Abatement Technologies, and verify clearance with a borescope camera. In back-country estates where systems cycle hard on weekends then sit idle all week, coils develop biofilm faster than standard schedules predict. We adjust our cleaning intervals accordingly.

Evaporator Coil Cleaning

Air Handler Cleaning

This is where Greenwich diverges from every nearby market. In 06831, we regularly encounter properties with six to eight separate air handlers. Each requires individual access, brushing, and vacuuming. A technician who quotes by the home instead of by the unit will underbid, rush the job, and miss secondary zones. We quote per air handler. It’s the only honest way to price these properties, and it’s why our estate clients in Greenwich stay with us for years. Our crews carry enough Rotobrush heads and Nikro vacuum hose to handle multiple units without rescheduling.

Air Handler Cleaning

Blower Cleaning

The blower assembly moves conditioned air through your entire system. When dust accumulates on blower fins, airflow drops and the system runs longer to hit temperature. In older downtown homes near 06830, where ductwork was retrofitted around original radiator systems, blowers often work against higher static pressure than the system was designed for. A dirty blower in that environment fails faster. We remove the housing, clean the wheel and motor assembly, and check amp draw before reassembly.

Blower Cleaning

Condenser Cleaning

Outdoor condensers in Greenwich take abuse from Long Island Sound salt air, pollen from the abundant oak and maple canopy, and the leaf debris that collects on properties with mature landscaping. We fin-comb where needed, wash coils with low-pressure foaming cleaner, and clear the condensate drain. A clean condenser runs cooler, draws less power, and lasts longer through the humid Connecticut summers.

Condenser Cleaning

Coil Treatment

After cleaning, we offer an optional coil treatment using Aprilaire-authorized antimicrobial coating. This isn’t a substitute for physical cleaning, but it does slow biofilm regrowth in the high-humidity conditions that define Greenwich’s coastal climate. We recommend it particularly for weekend-residence properties where moisture sits stagnant in the coil pan from Monday through Thursday.

Coil Treatment

Heat Exchanger Cleaning

In older downtown Greenwich homes with original furnaces still in service, heat exchanger cleaning requires care. We inspect for cracks or corrosion with a camera first. If the exchanger is sound, we clean it; if not, we tell you plainly and recommend replacement. No scare tactics, no upsell. Just an honest assessment you can act on.

Trusted Brands We Service in Greenwich

We stock parts and maintain equipment from Rotobrush, Nikro, Abatement Technologies, and Aprilaire, the same brands serious HVAC contractors specify for their own installations. For Greenwich customers, this means faster turnaround and no waiting for specialty items to ship. We also service systems with Honeywell and Guardsman air cleaners, common in the high-end installations found throughout 06831. Our technicians carry the brush heads, vacuum attachments, and coil fin combs matched to these brands, so we’re not improvising with generic tools that might damage your equipment.

Common HVAC Cleaning Problems We See in Greenwich Homes

  • Bidding by the home instead of by the air handler. A crew quotes a flat rate for a “whole house” cleaning, then discovers six separate systems in a back-country estate. They rush, miss secondary zones, or try to renegotiate at the door. We quote per unit from the start. No surprises.
  • Weekend-only cycling patterns in commuter homes. Many 06831 properties serve as primary weekend residences for NYC-based finance professionals. Systems run hard Friday through Sunday, then sit idle. Without continuous airflow, dust and moisture settle, and biofilm builds faster than standard cleaning intervals assume. These properties need more frequent attention, not less.
  • Generic brushes on retrofitted downtown ductwork. The 1920s-1950s colonials and Tudors near downtown 06830 often have ductwork that was retrofitted around original steam or hot-water radiator systems. Mixed-material plenums, galvanized-to-fiberglass transitions, and irregular runs require custom brush heads and controlled vacuum pressure. A standard brush can scratch fiberglass liners or delaminate old joints, releasing fibers into the airflow.
  • Neglected secondary zones in large estates. Guest wings, finished basements, and pool houses have their own air handlers that may run independently from the main system. These units are easy to overlook during routine maintenance, and they’re often where we find the worst biofilm buildup due to intermittent use.

Pricing for HVAC Cleaning in Greenwich, CT

Service Typical Range in Greenwich
Single-system evaporator coil cleaning $340-$520
Blower cleaning (single unit) $280-$420
Condenser cleaning $220-$380

Full estate cleaning, 6-8 air handlers $1,200-$4,800
Coil treatment (per unit, optional) $85-$140

What moves you within these ranges? Number of air handlers is the biggest factor in Greenwich, especially in 06831. Accessibility matters too, some downtown homes have ductwork buried behind original plaster or accessed through tight crawlspaces. The condition of the system affects time on site; a unit that hasn’t been cleaned in fifteen years takes longer than one on a three-year cycle. We inspect with a camera first, then give you a firm price before starting. Estimates are free. Call (844) 685-6342.

Standing offers: $50 off any repair over $250, free second opinion on any written estimate, $89 seasonal tune-up, and a permanent 5% senior and veteran discount.
