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 HVAC Cleaning Across Wellesley
HVAC cleaning in Wellesley means something specific here: older ductwork, tight mechanical rooms, and a housing stock that runs from stone-and-slate to modern frame. Most Wellesley systems we see need the full treatment – coil, blower, and duct – because they serve year-round heating and cooling loads, not just summer AC. A standard HVAC cleaning in Wellesley runs $450 – $825 depending on system size, with a camera inspection before any quote. Call (737) 727-2314 and we’ll walk you through exactly what your system needs.
Why Cardinal Air Duct Cleaning Is Wellesley’s Preferred HVAC Cleaning Company
The reason Wellesley homeowners call Cardinal comes down to one thing: we quote a flat per-system price and stick to it. No per-vent math, no add-ons at the door. What you see on the written estimate is what you pay, and that estimate comes only after a camera inspection of your actual ducts. For an 80-year-old house off Washington Street, that matters because the duct runs may be original sheet metal with hairpin turns and hidden returns.
Every crew that works in Wellesley is background-checked and uniformed, and you’ll know the technician’s name before they arrive. They run Rotobrush agitation equipment, Nikro HEPA vacuum rigs, and Abatement Technologies containment when needed. That’s the same gear commercial duct cleaners use, not a shop vac attached to a drill. And our 365-Day Done Right Promise applies to every job in Wellesley without exception. If the work isn’t right within a year, we come back and correct it at no charge.
AC Cleaning in Wellesley
AC Cleaning in Wellesley focuses on the components that actually move and cool air: the evaporator coil, condenser coil, blower, and the air handler interior. In Wellesley, where central AC runs from May through September and old ductwork is common, the coil picks up a film of dust and pet dander within a few seasons. That film insulates the coil, reduces heat exchange, and forces the compressor to run longer. The result is higher electricity use and a warmer house on the hottest afternoons.
For most Wellesley homes, a full AC cleaning with coil and blower service runs $350 – $650, and we recommend combining it with duct cleaning when the system has not been opened in several years. The two jobs share access points, so doing them together costs less than scheduling them separately.
Coil Inspection and Evaporator Service
We open the air handler, inspect the coil face, and document what we find with photos before touching anything. If the coil is caked, we apply a foaming cleaner and rinse it with low pressure so fins don’t bend. You see the before and after of your own coil, not a stock photo.
Blower Wheel and Housing
The blower wheel in a Wellesley system often runs for eight months a year, and dust builds on the fan blades unevenly. That throws the wheel out of balance, wears the bearings, and makes the motor draw more current. We pull the blower assembly, clean each blade, and reseat it properly.
Evaporator Coil Cleaning in Wellesley
Evaporator Coil Cleaning in Wellesley is the single highest-impact service we do for AC performance. The evaporator coil sits inside the air handler, where it absorbs heat from return air. In Wellesley, with its mature tree canopy and older houses, fine organic dust and pollen find their way into the return stream even when filters are changed regularly. Once the coil is coated, airflow drops and the system freezes up or short-cycles.
A standalone evaporator coil cleaning in Wellesley runs $225 – $400 depending on access. On some 1920s systems near Wellesley Square, the coil is buried behind original duct connections and takes two hours to reach. On newer air handlers, it’s a 45-minute job. Either way, the price is set after inspection and it does not move.
Why Coil Cleaning Prevents Bigger Repairs
A dirty evaporator coil doesn’t just reduce cooling; it adds frost and can send liquid refrigerant back to the compressor. That’s a multi-thousand-dollar failure. Coil cleaning is cheap relative to that. In Wellesley, where many systems are 15+ years old, a clean coil extends the working life of the whole condensing unit.
What to Watch For
If your AC runs constantly on warm days but the house won’t hold temperature, or if you notice ice on the copper line at the air handler, the evaporator coil is the first thing we check. Sometimes it is a refrigerant issue, and we’ll tell you that directly if it is. We do not sell coil cleaning when the real problem is a leak.
Trusted Brands We Service in Wellesley
We service and maintain the equipment Wellesley homeowners already have. That includes Honeywell and Aprilaire media cabinets, Guardsman filtration products, and the full line of modern condensing units paired with older Carrier, Trane, and Rheem air handlers. Our techs carry common filter sizes and access panels for Aprilaire and Honeywell housings, which speeds up turnaround for Wellesley jobs. We also use Rotobrush and Abatement Technologies equipment on the cleaning side, so the tools match the quality of the systems we open.
Common HVAC Cleaning Problems We See in Wellesley Homes
- Hidden returns in pre-1950 houses: Many Wellesley homes have unlined wall cavities acting as returns, not dedicated duct runs. These collect a century of debris and cannot be cleaned by a standard vacuum alone; camera inspection shows exactly what is in there before we touch it.
- Flex duct collapses in 1990s colonials west of Cliff Road: The plastic inner liner of flex duct degrades over time, and in some Wellesley systems we find it pinched or disconnected inside the chase. Cleaning a collapsed run is pointless; we flag it and clean only what is intact.
- Filter bypass at the air handler: In older Wellesley mechanical rooms, the filter slot is often slightly oversized, allowing dust to slip around the filter and into the blower. We check the seal and recommend a filter gasket when needed.
- Oversized systems short-cycling: Some Wellesley homes have AC units sized for a larger house, which short-cycles and leaves coils wet. That leads to mold bloom on the evaporator and a musty smell at the registers. Cleaning addresses the symptom, and we’ll tell you if resizing is the real fix.

FAQs About HVAC Cleaning in Wellesley
For most Wellesley homes, every 5 to 7 years is genuinely sufficient, and only if the inspection shows visible dust, pet hair, or construction debris in the supply and return runs. If you have allergies, a recent renovation, or a pre-1950 house with unlined returns, the interval may be shorter. If your ducts are clean, we will tell you they are clean and recommend you wait. Call (737) 727-2314 for an honest camera inspection before booking a cleaning.
Per system. We never quote per vent or per register, because that pricing model punishes Wellesley’s larger older homes where vent count varies and system complexity is the real cost driver. One flat price for your entire system is handed to you in writing before any work begins, and it does not change.
It means we photograph your actual ducts, coils, and registers before the job, then photograph the same locations after cleaning. You see the inside of your own return chase and supply runs, not a stock image or a generic illustration. The photos are sent to you by link, along with your invoice, before the crew leaves the property.
We run Rotobrush rotary brush systems for agitation, Nikro HEPA-rated vacuum extraction for negative-pressure capture, and Abatement Technologies containment units when we need to seal off a work area. We service and maintain Honeywell, Aprilaire, and Guardsman filtration components on the residential side. The equipment is professional-grade because Wellesley’s older ductwork requires it.
Yes, when you book the full HVAC cleaning package. The job includes the evaporator coil, blower assembly, air handler interior, and the supply and return ducts. In Wellesley, where AC runs for months and older coils are access-hard, we recommend the full package rather than ducts alone. If your coil is clean and only the ducts need work, we’ll tell you that and price it accordingly. Call (737) 727-2314 for a precise quote.
