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 Cardinal Air Duct Cleaning Is New Haven’s Preferred HVAC Cleaning Company
New Haven is a fixed-geography city. It sits on Long Island Sound, so the humidity that rolls through summers gets pulled directly into return ducts and coils. Combine that with the age of the housing stock here and you get a very specific set of HVAC problems that a generic cleaner from the suburbs doesn’t deal with nearly as often.
We built our process around New Haven’s reality. Multi-unit homes are the norm here, not the exception. That changes how pricing has to work and it changes how a job gets inspected. Our team runs Rotobrush agitation tools and Nikro HEPA extraction units, with Abatement Technologies containment when a job calls for it. Every technician is background-checked and in uniform. You’ll know the tech’s name before the door opens.
Cardinal Air Duct Cleaning is part of the Relay Home Co. family, founded 2005. Omar Haddad leads our New Haven work, and the standard he holds is simple: a written price in your hand before a single duct is touched, photographic proof of the work when it’s finished, and a full 365-Day Done Right Promise on every job. If the work isn’t right within a year, we come back and make it right at no charge.
AC Cleaning in New Haven
AC Cleaning in New Haven means removing the accumulated grime from your evaporator coil, condenser, and blower assembly so the system actually cools again. In a city where July humidity regularly pushes dew points past 70°F, a fouled coil doesn’t just cost efficiency. It turns a window-unit apartment or a central-air home into a damp, musty box. A full AC cleaning here typically runs $180 – $380 depending on access and how heavily the coil is fouled.
Coil Inspection and Cleaning
The coil is the first place New Haven humidity leaves its mark. Salt-laden air from the Sound accelerates surface corrosion and gives dust something to cling to. We clean coils with professional coil treatments that cut through the biofilm without warping fins.
Blower and Airflow Service
Blower wheels in New Haven’s older homes collect a dense mat of dust and pet hair. A loaded blower moves less air, so the system runs longer to hit the same setpoint. Cleaning it restores airflow and lowers runtime, which matters in a city where electricity rates are already high.
Evaporator Coil Cleaning in New Haven
Evaporator Coil Cleaning in New Haven is the single highest-impact service we perform in this city’s older buildings. The evaporator coil sits inside the air handler and does the actual heat exchange that cools your air. When it’s covered in a damp dust blanket, your AC’s cooling capacity can drop by 30 percent or more while still drawing the same power. A standalone evaporator coil cleaning in New Haven runs $150 – $300 for a standard residential unit.
When the Coil Is the Whole Problem
In pre-1950 homes around East Rock and Fair Haven, we frequently find evaporator coils that haven’t been opened since the system was installed. The coil is buried behind panels that homeowners are reasonably nervous about removing. That’s fine. We handle it with proper coil cleaners, drip pans, and drain line flushing.
Humidity’s Slow Damage
The moisture that air conditioners strip from New Haven air condenses on the coil surface. When that coil is dirty, the moisture pools instead of draining cleanly, and you get microbial growth that eventually smells. Cleaning the coil and flushing the drain line restores proper dehumidification as a side effect of proper cooling.
Trusted Brands We Service in New Haven
We work on systems that carry Aprilaire filtration components, Guardsman-rated coils and pans, and most major HVAC brands found in New Haven’s single-family and multi-family inventory. Our equipment fleet includes Rotobrush rotary brushes for duct agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units for homes with mold, construction dust, or asbestos-era debris concerns. Because we service these brands daily, we know their access quirks and weak points, and we stock common filters and replacement components locally so New Haven homeowners don’t wait a week on a parts order.
Common HVAC Cleaning Problems We See in New Haven Homes
- Multi-unit air handler confusion. A triple-decker in New Haven is three separate systems in one frame, but often only one condenser and one furnace room. If a cleaner quotes per-vent without mapping the actual units, the final invoice explodes. We price per system upfront and verify the unit count during the initial walkthrough.
- Original ductwork with return leaks. Homes built before duct sealing was standard often pull return air through chase walls, joist bays, and gaps in the plaster. That means one unit’s return can be drawing air from a neighboring apartment, pulling in cooking grease, cigarette residue, or stale bathroom air. Camera inspection catches this before cleaning starts.
- Coils loaded with Sound humidity. New Haven’s coastal air keeps coils damp for months at a time. That sticky surface captures dust fast, and the dust holds moisture, which accelerates coil corrosion. A coil that’s never cleaned in an East Shore home often needs a treatment, not just a rinse.
- Blower motors caked from shared walls. In multifamily homes with shared wall cavities, the blower wheel becomes a lint magnet. Returns pull from adjacent units and the blower just accumulates. It loses balance, runs louder, and eventually overheats. Cleaning the blower extends the motor’s life and quiets the system.
Pricing for HVAC Cleaning in New Haven, CT
We give one flat price per system before work starts. A standard single-family HVAC cleaning in New Haven runs $350 – $650 for the full scope: supply ducts, return ducts, air handler, blower, and evaporator coil. A triple-decker or multi-unit property gets a per-system quote, not a per-vent quote. If your home has two systems, you get two system prices. If it has three, you get three. No surprises when the tech finds a third air handler. No “price at the door” adjustment. Call (737) 727-2314 and we’ll give you an exact written figure after a short phone walkthrough of your home’s layout.

FAQs About HVAC Cleaning in New Haven
We price per system, not per vent. A three-unit triple-decker gets three system prices, each covering that unit’s ducts, air handler, blower, and coil. The flat per-system quote is written before work starts and does not change when we find the building has three air handlers instead of one. Call (737) 727-2314 for an exact quote based on your building’s layout.
Most New Haven homes need a full HVAC cleaning every 3 – 5 years. Homes with pets, smokers, recent renovations, or a lot of Sound-side humidity may need it closer to every 2 – 3 years. If you just moved into a pre-1950 home in New Haven and don’t know the ductwork history, that’s a solid reason to do it once and establish a baseline. If you’re in a newer build with no pets and no allergies, you probably don’t need it yet. We’ll tell you that honestly.
No. We schedule work deliberately so every job gets the time it needs, and we don’t cut corners to hit a same-day deadline. What we do promise is a scheduled arrival window you can track live, a written price before work begins, and before-and-after photos of your own ducts when the job is done.
We work on all major residential HVAC brands and stock common replacement filters and parts for Aprilaire, Guardsman, and other systems common in New Haven. Our cleaning equipment includes Rotobrush rotary brushes, Nikro HEPA extraction vacuums, and Abatement Technologies containment units when a job warrants it.
Yes. Every job includes before-and-after photographs of your own ducts, coils, and blower assemblies. You see what we saw when we opened the system, and you see the result. The photos are delivered with your digital invoice, which you can pay from a link on your phone.
