Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why Greenwich Homes Are Different
Greenwich air duct work is shaped by the housing stock itself. The town has a heavy concentration of pre-war and mid-century homes: slate-roofed Georgians off Round Hill Road, Victorian-era houses in Belle Haven and Cos Cob, and a surprising number of 1920s-era estates that have been renovated, expanded, re-renovated, and expanded again. That matters for one practical reason: original duct runs are rarely rectangular and predictable. We regularly encounter 90-year-old galvanized ducts with hard 90-degree turns, rusted joint seams, and return plenums that were built before modern airflow standards existed. In central Greenwich, homes built into bedrock often have ductwork packed tightly in crawlspaces and basements with low clearance, so cleaning requires rotary brush heads that can navigate tight offsets rather than a straight shot from a single access point. Coastal salt air in Old Greenwich and Riverside accelerates surface corrosion on exposed boots and registers, while newer construction along North Street and King Street tends to trap drywall dust and construction debris from the build itself. None of this is a problem for the right equipment, but it does mean cookie-cutter cleaning services that blast a vacuum through the register won’t touch what’s actually caked onto Greenwich duct walls.
Our Main Greenwich Services
Two jobs account for most of what Greenwich homeowners call us for: dryer vent cleaning and full air duct cleaning, with HVAC cleaning close behind. Below is where each one has its own dedicated Greenwich page, including local pricing and what the job involves.
Dryer Vent Cleaning in Greenwich
Greenwich mudrooms and laundry rooms regularly vent dryers through long vertical risers or basement-to-roofline runs: a 20-foot vent with three elbows is common in older homes, and that’s exactly the configuration where lint accumulates fastest. Coastal humidity in Old Greenwich and Riverside makes that lint sticky and dense rather than dry and fluffy, which is bad news for airflow and a real fire risk. Our techs run rotary brushes from Rotobrush through the full run, verify the termination point outside, and confirm airflow before they call the job done. For Greenwich-specific pricing and what to expect, see Dryer Vent Cleaning in Greenwich.

Air Duct Cleaning in Greenwich
This is the full-house treatment: source removal cleaning of supply ducts, return ducts, the main trunk line, and plenums. In Greenwich homes, we most often find a blend of construction dust from renovations, pet dander, and the fine gray silt that coastal New England air deposits year after year. We use negative-pressure extraction, which means the loosened debris goes directly into a HEPA-filtered Nikro vacuum, not back into your living room. Full details and a price breakdown live on the Air Duct Cleaning in Greenwich page.

HVAC Cleaning in Greenwich
This is the deeper job: cleaning the evaporator coils, blower motor, blower wheel, and the interior of the air handler or furnace cabinet. In Greenwich, where many homes run oversized HVAC systems in low-clearance mechanical rooms, we find blower wheels caked with a paste of dust and coil condensate. That buildup chokes airflow, shortens equipment life, and makes the system work harder through Fairfield County winters. See the full scope, equipment we use, and pricing on the HVAC Cleaning in Greenwich page.

What pushes a Greenwich job toward the upper end: heavily divided ductwork with limited access, extra-long dryer vent runs with multiple elbows, or homes where renovation debris has hardened inside duct walls and needs a second pass. Whatever the number ends up being, you get it in writing before we begin, and it does not change at the door.
