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.

AfterFast, Reliable Air Duct Cleaning Across Stamford
Air duct cleaning in Stamford typically costs $450 – $900 for a full system on a single-family home, with the exact price agreed in writing before any work begins. That’s the honest range for this market, where housing stock changes dramatically block by block. Our Air Duct Cleaning team works throughout Stamford regularly, from the prewar two-families near Glenbrook Road to the new high-rises downtown, so we know what’s inside these ducts and what it takes to clean them properly. Call (737) 727-2314 for a free estimate.
Why Cardinal Air Duct Cleaning Is Stamford’s Preferred Air Duct Cleaning Company
Homeowners across Stamford keep calling us for one reason that has nothing to do with coupons: we tell them the truth about their ducts. A two-family on the South End doesn’t get the same cleaning scope as a condo tower off Washington Boulevard, and pretending otherwise is how people get burned. We send background-checked, uniformed technicians who run Rotobrush agitation tools and Nikro HEPA vacuums, not a truck-mounted shop vac with a long hose. You know the tech’s name before they knock, and you get a written price before a single vent is opened.
We’re part of the Relay Home Co. family, founded in 2005, so every job in Stamford follows The Relay Standard: a live trackable arrival window, before-and-after photos of your own ductwork, and a digital invoice you can pay from your phone. Omar Haddad leads our team, and the standard he set is simple: if it’s not done right within 365 days, we come back and fix it. That’s the 365-Day Done Right Promise, and it applies to every booking in Stamford without exception.
Air Duct Cleaning Services in Stamford
Air duct cleaning services in Stamford cover the full loop your air moves through: supply ducts pushing conditioned air out, return ducts pulling it back, and everything between. Most Stamford homes need this done every 3 – 5 years, though a two-family with tenant turnover or a house with pets and old carpet may need it sooner. A standard single-family system in Stamford runs $450 – $700, and that price is locked in writing before we set up equipment, not after. We never quote per vent. One flat price per system, agreed up front.
Residential Duct Cleaning
We clean the ductwork in single-family homes, condos, and converted two-families across Stamford. Older homes in Glenbrook and Springdale often have disconnected joints and crushed flex runs that a camera inspection catches before cleaning starts.
Commercial Duct Cleaning
Offices, retail spaces, and multifamily buildings in downtown Stamford have different demands: stacked risers, multiple air handlers, and tenants who can’t be disturbed for long. We scope each system on site and quote a flat price for the building, not a per-register guess.

HVAC Duct Cleaning in Stamford
HVAC duct cleaning in Stamford means the whole air path, not just the vents in your floors. We use negative-pressure extraction, which means the loosened debris goes straight into the HEPA-filtered vacuum and not back into your living room. A typical Stamford home with one furnace and one air handler runs $500 – $900 depending on system size and access. If we find a rusted run or a disconnected joint during the scope, that’s included in the written price you approve before work starts.
Supply and Return Duct Cleaning
Your supply ducts push air out to every room; your return ducts pull it back to be conditioned. Both need attention in Stamford, especially in older homes where returns can pull air from unfinished basements and crawl spaces. We clean both, and we photograph both before and after.
Full System Cleaning with Video Inspection
Every Stamford job starts with a camera inspection of the duct interior. You’ll see what we see. After cleaning, you’ll see the same registers on camera again, clean. That’s before-and-after proof, not a checklist saying we were there.
Trusted Brands We Service in Stamford
We clean and maintain duct systems attached to all the major equipment found in Stamford homes: Trane, Carrier, Rheem, Lennox, Goodman, and Bryant furnaces and air handlers. We also stock Guardsman and Aprilaire filtration products locally, so if your media filter or UV unit needs replacement during a cleaning, we can usually swap it in the same visit. Abatement Technologies containment units let us work cleanly in occupied spaces, and Rotobrush agitation tools loosen debris that a vacuum alone can’t move. If it’s in a Stamford home, we’ve likely worked on it before.
Common Air Duct Cleaning Problems We See in Stamford Homes
- Disconnected and crushed flex runs in older homes. Glenbrook and Springdale have a lot of ductwork installed decades ago, often with flex runs that have sagged, crushed, or pulled loose at the joints. Air leaks into wall cavities, and you pay to condition space you never use.
- Return trunks pulling from unsealed basements. Many South End and West Side homes run returns through damp, dusty basements. That pulls moisture and particulate into the system, which is why musty smells show up when the AC runs.
- Stacked high-rise systems with shared riser branches. Downtown condo buildings often route multiple units off a single air handler, so a clog in one branch affects neighbors on several floors. Scope has to be confirmed on site, not quoted from a phone call.
- Decades of tenant turnover in two- and three-family homes. Multi-unit rentals along the Post Road corridor often have years of occupancy layered into the ducts: dust, cooking residue, pet hair, and sometimes old pest debris. A proper cleaning resets the system.
Pricing for Air Duct Cleaning in Stamford, CT
We don’t quote per vent, and we don’t bait you with a teaser price that doubles once we’re inside. A standard single-family system in Stamford runs $450 – $700. Larger homes, multi-zone systems, or properties with multiple air handlers run $700 – $900. Commercial and stacked high-rise systems are scoped on site and quoted as one flat price for the building. What changes the price is what we find inside: the number of actual air handlers, the length of duct runs, the access to the mechanical room, and whether repairs like a rusted return run need to be included. You get that number in writing before any work starts. Call (737) 727-2314 for a free estimate on your Stamford system.

FAQs About Air Duct Cleaning in Stamford
Every 3 – 5 years for most Stamford homes, and you can skip it entirely if the ducts show no visible buildup, no mold, and no sign of pest contamination. Camera inspection tells the difference. If you’ve just renovated, have pets that shed heavily, or just moved into an older South End or Glenbrook home with unknown history, lean earlier. Call (737) 727-2314 and we’ll tell you honestly whether cleaning is even necessary before quoting you anything.
One flat price per system, always. Stamford’s housing stock makes per-vent pricing misleading: a South End two-family can have twice the registers of a downtown condo system, so per-vent quotes quietly overcharge some buildings and undercharge others. We scope the actual system on site and give you one number for the whole thing, in writing, before any work starts.
Yes. Every Stamford job includes before-and-after photos of your own duct interior, taken by camera at the registers. You see the ducts as they were when we arrived and as they are when we finish. The Relay Standard includes this photo documentation with every booking, along with a digital invoice you can pay from a link.
Duct cleaning is a scheduled job, not an emergency call. We don’t promise same-day service because it isn’t honest and it isn’t necessary for this kind of work. What we do offer is a live trackable arrival window once you’re booked, so you know exactly when we’re pulling up, and a live person answers the phone 24/7 if you need to reach us. Call (737) 727-2314 to schedule a visit.
We clean to NADCA standards, which means source removal: agitation tools loosen the debris, and negative-pressure extraction pulls it out through HEPA filtration instead of blowing it back into your home. You can ask to see the process, and we’ll walk you through what we’re doing and why. Our equipment includes Rotobrush brush systems and Nikro HEPA vacuums, not improvised shop-vac setups. The 365-Day Done Right Promise backs every job: if it’s not right within a year, we return and correct it at no charge. Call (737) 727-2314 for a free estimate.
