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.

AfterAir Duct Cleaning Company in Cos Cob, CT
Air duct cleaning in Cos Cob, CT for a typical 3 – 4 bedroom home runs $450 – $850 for a full system cleaning, depending on the number of returns, the condition of the ductwork, and whether you’ve added dryer vent or HVAC coil work. Most Cos Cob jobs take 3 – 5 hours and include before-and-after photos so you can see exactly what was removed. Call (737) 727-2314 and we’ll give you a written price before a single duct is touched.
Why Cos Cob Homes Are Different
Cos Cob sits near the Mianus River and the Long Island Sound shoreline, which means the air moving through your ducts carries real moisture for most of the year. That coastal humidity settles inside ductwork and gives dust something to cling to, so systems here collect a stickier, denser buildup than you’d see in drier inland towns. Homes off Valleywood Road, Bible Street, and River Road tend to show it faster – especially older Colonials and split-levels built before modern filtration was standard. When we open a return in Cos Cob, we typically find a mix of construction dust, pet hair, and the gray film that shoreline humidity leaves behind. Mechanicals in basements here also run against the damp; supply trunks near foundation walls can show surface rust that homeowners would never see without a camera.
That coastal moisture also makes regular dryer vent cleaning in Cos Cob a genuinely practical step. Vents running up through older wall cavities collect lint that humidity turns into a paste, and that restricts airflow faster than a dry vent ever would. It’s not a scare tactic. It’s what the geography does. You’ll find three distinct housing eras in Cos Cob – prewar cottages and capes near the river, mid-century splits in the hillier sections, and newer builds and renovations inland. Each one has different duct layouts and different access points, and the work goes differently in each. Call (737) 727-2314 and we’ll tell you what applies to your house, not the average house.
Our Main Cos Cob Services
The two calls we get most from Cos Cob homeowners are dryer vent work and full air duct cleaning, with HVAC coil and blower cleaning close behind. Each service has its own dedicated Cos Cob page linked below.
Dryer Vent Cleaning in Cos Cob
A clogged dryer vent in a Cos Cob home isn’t just an efficiency problem. It’s a fire hazard with a clear, known cause, and the fix is straightforward. We run a Rotobrush through the full vent run from the dryer connection to the exterior termination, then verify airflow with a meter so you’re not guessing. Older Cos Cob capes often have long, awkward vent runs – some snake 15 feet or more through a crawl space or up a finished wall – and those are exactly where lint builds fastest. Dryer Vent Cleaning in Cos Cob gives the full breakdown of service and pricing.
Air Duct Cleaning in Cos Cob
A full air duct cleaning in Cos Cob means every supply and return duct in the house gets cleaned from the register to the plenum, using a Nikro HEPA vacuum for negative-pressure extraction – that means the loosened debris goes straight into the vacuum, not back into your living room. We also remove and clean each register, and camera the main trunks so you can see the before and after yourself. Coastal homes here fill ducts with a stubborn mix of humidity-bound dust and pet dander that a basic filter change never touches. Air Duct Cleaning in Cos Cob covers the process, pricing, and what to expect.
HVAC Cleaning in Cos Cob
Your furnace or air handler circulates every cubic foot of air in the house, and in Cos Cob it’s pulling that air through a blower wheel and evaporator coil that most homeowners never see until something fails. We open the unit, pull the blower assembly, and clean the coil and drain pan so the system moves air the way it’s designed to. Cos Cob basements are tight and damp, which means coils here get a tacky coating of dust that cuts efficiency more than you’d think. HVAC Cleaning in Cos Cob has the full scope and honest cost.
