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 Westborough
HVAC cleaning in Westborough, MA typically costs $450 – $750 for a complete system cleaning of a standard single-zone home, and most jobs are completed in 3 – 5 hours. We serve the entire Westborough area with written pricing handed to you before we touch a single duct. That’s how HVAC Cleaning should work: you know the number up front, we do the job, and you see before-and-after photos of your own ducts on your own phone before you pay.
We know Westborough’s housing stock well. The 1920s colonials near the rotary, the split-levels off Lyman Street, the newer subdivisions along Route 9 and I-495. They all present different ductwork and air handler situations, and we quote accordingly. Call (737) 727-2314 and a live person answers. No voicemail loop, no phone tag.
Why Cardinal Air Duct Cleaning Is Westborough’s Preferred HVAC Cleaning Company
Westborough homeowners call us because we’re straight about what HVAC cleaning actually involves. Omar Haddad runs this location, and he holds every job to the Westborough Relay Standard: a live trackable arrival time, background-checked technicians in uniform, and a written price before any work begins. You know who’s coming and what the job costs before the van pulls up.
Our crews carry professional-grade equipment, not truck-mounted shop vacs. Rotobrush agitation systems, Nikro HEPA vacuums, and Abatement Technologies containment units. When we clean an air handler in a Westborough basement, we set up negative-pressure extraction so loosened debris goes into the vacuum, not back into your living room.
And every job is covered by the 365-Day Done Right Promise. If the work isn’t right within a full year, we come back and correct it at no charge. That’s not a limited-time thing. It applies to every booking, across Westborough, without exception.
AC Vent Cleaning in Westborough
AC vent cleaning in Westborough gets at the visible part of your HVAC system: the supply and return registers. In a Westborough home, that means removing each register, brushing the duct boot, and vacuuming accessible branch runs. It makes sense when you see dust streaks on the walls near vents, when rooms start smelling stale, or when your AC has been running hard through a full Massachusetts summer.
For most Westborough homes, AC vent cleaning runs $25 – $60 per register when booked as part of a full system cleaning. Standalone vent-only work starts around $150 and goes up from there, but we’ll tell you plainly: if the duct trunk and air handler haven’t been cleaned, vent cleaning alone won’t fix much. We’ll never sell you a partial fix.
Register Pulling and Boot Brushing
Every register comes off, and we inspect the boot with a camera before cleaning. You’d be surprised how often a boot holds a decade of pet hair and construction dust behind what looks like a clean vent face.
Branch Run Vacuuming
We use a HEPA-filtered vacuum on branch runs where accessible. If a branch run is flex duct and we can reach it, we clean it. If it’s buried behind a finished basement ceiling, the camera tells us whether it’s worth opening.
Furnace Duct Cleaning in Westborough
Furnace duct cleaning in Westborough is the heavy lifting. This means cleaning the supply trunk, the return trunk, and the plenum, then running agitation tools through every branch line accessible from the mechanical room. In older Westborough houses, the return trunks are often lined with decades of dust pulled in from unheated attics and basements, and that’s where the real work sits.
Most Westborough furnace duct cleanings run $350 – $500 for a standard single-furnace home with up to about 15 runs. Larger homes with long attic trunk lines and multiple zones can run $600 – $800. But the price is agreed before we start, and it doesn’t shift at the door. One flat price per system.
Trunk Line Agitation
We run Rotobrush agitation tools down the trunk lines to break debris loose from duct walls. Then the negative pressure pulls it out at the source. That’s the part that separates professional cleaning from blowing air around.
Air Handler and Filter Inspection
We inspect the air handler, blower wheel, and filter housing while the system is open. In Westborough homes with finished basements, the air handler often sits in a tight closet, and that access point matters more to the price than the number of vents.
Trusted Brands We Service in Westborough
Our Westborough crews work on furnaces and air handlers from every major brand found in Massachusetts homes: Carrier, Trane, Lennox, Rheem, Goodman, Bryant, and more. We stock common Aprilaire filter sizes and Guardsman parts on the truck so we can replace a filter housing or coil panel the same visit without making you wait. If your furnace is old enough to remember the Route 135 repave, we’ll still clean it properly and tell you honestly if it’s reached the point where cleaning won’t buy you much. We’d rather be straight with you than sell a service you don’t need.
Common HVAC Cleaning Problems We See in Westborough Homes
- Insulation dust in the return trunks. Older Westborough homes with unheated attics pull fiberglass and cellulose dust into the returns. By the time you see gray puffs from the registers, the trunk needs a real source removal, not just a register vacuuming.
- Per-vent pricing on long attic and basement runs. A lot of companies in this area price per vent, which can balloon fast on Westborough homes with long trunk lines. The real work is in the trunk and air handler, and that’s what our flat price reflects.
- Disconnected flex runs behind finished ceilings. We find flex duct that’s slipped off its collar in finished basements more often than you’d think. The system runs, but it’s blowing conditioned air into a joist bay. A camera inspection catches it.
- Clogged evaporator coils on AC systems. Westborough summers aren’t long, but they’re humid. Coils collect a sticky film, airflow drops, and the AC runs longer to hit the same setpoint. Coil cleaning is part of what we do.

FAQs About HVAC Cleaning in Westborough
A full HVAC cleaning in Westborough runs $450 – $750 for a typical home, and no, we don’t price per vent. The per-vent model falls apart on Westborough homes with long attic and basement trunk runs. We quote one flat price per system after we see the air handler access and duct layout. Call (737) 727-2314 and we’ll give you a written number before the work starts.
Every 3 – 5 years for most Westborough homes, but the honest answer depends on what the camera shows. Older homes with unheated attic runs collect insulation dust faster. Newer tight construction recirculates the same air, and if a renovation left drywall dust in the returns, one cleaning right after the project might be all you need. We’ll tell you if your ducts don’t need cleaning yet.
It means we don’t just blow air through the registers. We agitate debris off the duct walls, then the Nikro HEPA vacuum pulls it out at the source under negative pressure. The loosened material goes into a sealed containment unit, not back into your living room. That’s the standard Abatement Technologies equipment is built for, and it’s the standard we hold on every Westborough job.
Yes. HVAC cleaning covers the furnace, air handler, evaporator coil, blower, supply and return trunks, branch runs, and registers. We work on Carrier, Trane, Lennox, Rheem, Goodman, Bryant, and essentially any furnace or AC found in a Westborough home. If your unit is older, we’ll tell you straight whether cleaning will still make a difference.
We schedule most Westborough jobs within 2 – 4 business days, not same day. And yes, every job includes before-and-after photos of your own ducts, sent by link so you can see exactly what was in there and what it looks like after. That’s part of The Relay Standard, along with a live trackable arrival time and a digital invoice. Call (737) 727-2314 to book.
