We know Old Greenwich homes the way only specialists who work here regularly can. The mix of pre-war shoreline houses near Tod’s Point and newer rebuilds closer to Binney Park means duct systems here vary wildly, and so do the problems inside them. What doesn’t vary is our process: source removal with real negative pressure, HEPA-rated filtration, and before-and-after photos of your actual ducts. No bait pricing, no per-vent games, no mystery charges.

Why Cardinal Air Duct Cleaning Is Old Greenwich’s Preferred HVAC Cleaning Company

Omar Haddad leads every Old Greenwich job with a simple standard: you see what we see. We hand you a written price for the whole system before work starts, then we document everything with before-and-after photographs while the job is in progress. Old Greenwich homeowners tell us the same thing again and again: they called us because someone else quoted a low per-vent figure and then tried to double the invoice once the technician was inside.

We answer the phone. A live person picks up 24/7, and that’s not a call center script reading your number back at you. You’ll speak with someone who knows HVAC cleaning and can schedule you directly. Our background-checked, uniformed technicians arrive with a live trackable arrival window through The Relay Standard, so you’re not sitting around waiting on a four-hour estimated block.

Part of the Relay Home Co. family, founded in 2005, we’re held to The Relay Visibility Guarantee. That means every Old Greenwich job includes a digital invoice you can pay from your phone, before-and-after photo documentation, and a written guarantee on any repair work. If the work isn’t right within 365 days, we return and fix it at no charge. That’s the Done Right Promise, and it applies to every job without exception.

AC Vent Cleaning in Old Greenwich

AC vent cleaning in Old Greenwich homes means more than wiping down the visible registers. The real work happens inside the duct runs and at the air handler, where years of condensation, dust, and sometimes mold or mildew from tidal-adjacent basement humidity have accumulated. In homes along Shore Road and the side streets off Sound Beach Avenue, we routinely find return-air grilles that look clean while the return trunk behind them is carrying a thick debris mat that reduces airflow and pushes dust back into living spaces. A full AC vent cleaning for a typical Old Greenwich home runs $300 – $500 when done as part of a complete system cleaning.

Register and Grille Deep Cleaning

We remove each register and grille, clean both sides, and vacuum the immediate duct opening. In older Old Greenwich colonials, the register boots themselves often hold a surprising amount of fine particulate that standard surface dusting never touches.

Supply and Return Duct Agitation

Using a Rotobrush rotary brush system and Nikro HEPA vacuum running in negative pressure, we agitate the interior walls of your supply and return ducts to physically dislodge caked-on debris. Negative-pressure extraction means the loosened material goes straight into the vacuum, not back into your living room. That’s the difference between source removal and a surface-level cleaning that leaves the problem on the duct walls.

Furnace Duct Cleaning in Old Greenwich

Furnace duct cleaning in Old Greenwich addresses the heating-season buildup that accumulates when your system runs for months at a time through the winter. Homes near Binney Park and the residential streets off Havemeyer Lane often have basements that stay damp through the shoulder seasons, and that moisture finds its way into the return ductwork, where it bonds with dust and forms a stubborn layer that standard vacuums can’t touch. A complete furnace duct cleaning for a typical Old Greenwich home runs $450 – $750 when the air handler and blower motor are included, which they always are in our flat per-system price.

Heat Exchanger and Blower Cleaning

The blower motor pulls air across the heat exchanger and pushes it through your supply ducts. If the blower wheel is caked with debris, airflow drops and your furnace works harder to move the same amount of warm air. We clean the blower assembly, check the heat exchanger for visible buildup, and restore proper airflow before we move to the duct runs themselves.

Return Trunk and Air Handler Cleaning

This is where we find the most debris in Old Greenwich homes. The return trunk pulls air from your living spaces down into the basement or utility room, and it’s usually the dirtiest part of the system. We clean the full return path, from the grilles to the air handler, and document every section with photographs so you can see the difference on your own screens.

Trusted Brands We Service in Old Greenwich

We work on equipment from every major manufacturer installed in Old Greenwich homes, including Honeywell, Aprilaire, Guardsman, and Abatement Technologies filtration products. Whether your system was installed in a 1920s shoreline colonial near Tod’s Point or a 2018 rebuild off Havemeyer Lane, our technicians arrive with professional-grade tools and know how to service your specific equipment without a learning curve. We stock common filtration products and coil treatments, and we can order brand-specific parts quickly for Old Greenwich customers.

Common HVAC Cleaning Problems We See in Old Greenwich Homes

• Basement humidity in tidal-adjacent homes: The water table near the shoreline keeps many Old Greenwich basements damp through spring and fall. That moisture draws dust and debris to duct walls and creates the musty return-air smell so many homeowners notice when the system first kicks on.
• Pre-war duct runs with inadequate returns: Many 1920s and 1930s colonials in Old Greenwich were retrofitted for central air later, and the return paths weren’t always sized correctly. The result is airflow that starves the system, pulling dust through whatever gaps exist and depositing it on the coil and blower.
• Construction dust from rebuilds and renovations: Newer rebuilds off Shore Road and elsewhere in Old Greenwich often have drywall dust and construction debris settled in the ducts from the build itself. That dust circulates for years unless it’s professionally extracted.
• Pet dander and hair in homes near the water: Old Greenwich homes with dogs or cats that spend time outdoors track in fine particulate that eventually finds its way into the return ducts. We see mats of dander and hair in the return trunks of multi-pet homes regularly.
