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 Shrewsbury
HVAC cleaning in Shrewsbury typically costs $395-$780 for a full-system cleaning of a single-family home, and most jobs are completed in 4-7 hours. That price includes the air handler, evaporator coil, blower assembly, and all accessible supply and return duct runs. The real point for Shrewsbury homeowners is what gets found once we open the system: in this town, we routinely uncover disconnected flex runs, sagging attic duct sections, and mold growth inside plenums that no filter change would ever reveal. If you live in Shrewsbury and your forced-air system is original to the house, call (806) 606-6902 for a written price before any panel comes off.
Our crews work the neighborhoods along Route 9, around Lake Street, and through the subdivisions off Grafton Street and Holden Street every week. We know this housing stock: 1980s and 1990s colonials and split-levels with original flex-duct routed through unconditioned attic spaces. That matters because cleaning these systems is a different job from cleaning a newer home in Framingham or a 1950s cape near the old village center. We write that difference into the scope, not into the price as a surprise.
Why CleanRun Air Duct Cleaning Is Shrewsbury’s Preferred HVAC Cleaning Company
We built the company in 2013 on a rule called Haven Standard Clause 1: a written price before any work starts. That rule exists because the duct cleaning industry earned its reputation on $79 coupons that turned into $900 invoices once the technician was in the driveway. We have never played that game, and we never will. Tomas Reyes, who runs our crews, trains every technician to photograph the inside of every duct run before and after cleaning, so you can see the difference between source removal and vacuum noise. That photo record is a standard deliverable, not an upsell.
Shrewsbury homeowners tend to do the research before making contact. They ask what equipment we use, whether we are insured, whether the tech will be background-checked. Good questions. We run Rotobrush and Nikro negative-pressure extraction units with HEPA filtration, our technicians are background-checked and uniformed, and every one of them will tell you their name before they walk in your door. The 365-Day Done Right Promise is printed on every work order: if the job isn’t right, we make it right. Written. Not a courtesy.
Response time to Shrewsbury is typically 2-4 business days for a scheduled cleaning. We coordinate dispatch from our Boston office, and Shrewsbury is a regular stop on our crew routes, not a distant outpost. If you have a written quote from another company, we’ll put our number next to it in writing. That is Haven Standard Clause 4, and it costs nothing.
Our HVAC Cleaning Services in Shrewsbury
Air Handler Cleaning
The air handler is where Shrewsbury’s five-month heating seasons and humid summers meet. Every winter, air from your return ducts carries whatever is in the ductwork into the blower housing; every summer, Lake Quinsigamond moisture condenses on the cooling coil and drains into the pan. We remove the blower motor for direct cleaning, clean the housing, the blower wheel, and the accessible interior surfaces, and document the before and after with photos. In split-levels off Route 9, we regularly find so much debris on the blower wheel that airflow is reduced by 20% or more.
Evaporator Coil Cleaning
A dirty evaporator coil is the quiet reason a Shrewsbury home’s air conditioning runs longer and cools less. Dust and pet hair from five-plus months of heating settle onto the coil, then summer humidity turns that layer into a damp mat that insulates the coil and blocks heat transfer. We clean the coil in place where accessible, using coil-safe cleaning solutions, and we photograph the coil before and after so you can see the difference. If the coil is too fouled for in-place cleaning, we’ll tell you and quote the full removal-and-flush option in writing before work proceeds.
Heat Exchanger Cleaning
This is the component Shrewsbury homeowners rarely think about until the furnace won’t fire efficiently. A fouled heat exchanger pushes more of the burner’s heat up the flue instead of into your home. In 1980s and 1990s systems, we commonly find a layer of fine ash and dust on the exchanger surfaces that accumulated over decades of town-gas and oil-heat run cycles. Cleaning the heat exchanger improves combustion efficiency and reduces the strain on the furnace itself. We do this as part of the full-system cleaning and include photos in your record.
Condenser Cleaning
The outdoor condenser unit takes a beating in Shrewsbury’s freeze-thaw winters and pollen-heavy springs. The fins clog with cottonwood, maple seed, and grass clippings, and the coil gets caked with road salt drift and soil splash. We clean the condenser coil, straighten fins where needed, clear the surrounding clearance, and check the refrigerant line insulation and electrical connections for visible wear. This is part of the full-system cleaning, not a bolt-on.

BeforeAfterTrusted Brands We Service in Shrewsbury
Our technicians are trained to service and clean forced-air systems across all major brands, and in Shrewsbury we see a concentration of Carrier, Trane, and Bryant equipment from the 1980s and 1990s, plus a growing number of Goodman and Rheem units installed during the early-2000s renovation wave. We run professional-grade extraction and filtration equipment from Rotobrush and Nikro, and we carry Guardsman coil cleaning products because they are effective on aluminum and copper coil surfaces without the acid damage that cheap cleaners cause. For Shrewsbury customers, that brand-specific knowledge matters: a 1992 Carrier air handler has different panel access and coil geometry than a 2018 Rheem, and the difference should be in the method, not in the technician’s guesswork.
Common HVAC Cleaning Problems We See in Shrewsbury Homes
- Disconnected attic flex runs: The freeze-thaw cycling in unconditioned attic spaces above 1980s and 1990s Shrewsbury homes causes flex-duct connections to separate from duct-board plenums. When that happens, the return side pulls insulation and attic dust straight into the air handler. We find this on roughly one in three older Shrewsbury systems we open.
- Mold growth in supply plenums: Western Shrewsbury’s Lake Quinsigamond humidity condenses on poorly insulated supply ducts during summer. That condensation soaks into the duct’s interior surface, and within a season or two, mold begins forming inside the plenum. Cleaning removes the growth, but the real fix is resealing and insulating the runs so the condensation stops recurring.
- Degraded foil-scrim duct jackets: Original 1980s foil-scrim jacketing breaks down inside tight utility chases in Shrewsbury’s colonials. The jacket tears, the insulation pulls away, and the duct leaks conditioned air into the chase. Your furnace works harder, and your fuel bill climbs through five-plus months of heating season.
- Crushed duct sections in tight chases: The construction-era practice of routing flex-duct through narrow chases between floors means decades of settling, renovation pressure, and vibration have crushed or kinked many runs. A crushed section doesn’t just reduce airflow; it creates a debris trap that keeps re-contaminating the clean ductwork upstream.
Pricing for HVAC Cleaning in Shrewsbury, MA
Here are the real numbers for Shrewsbury’s market. A full-system HVAC cleaning for a typical 2,000-2,800 square foot colonial runs $395-$780.

FAQs - HVAC Cleaning in Shrewsbury
The original flex-duct runs in Shrewsbury’s 1980s and 1990s colonials and split-levels were routed through unconditioned attic spaces, where four decades of freeze-thaw cycling caused the connections to work loose and the duct tissue to sag or collapse. What we find is a return flex run that has separated from the air handler plenum, pulling insulation and attic dust directly into the blower. These failures are so common in Shrewsbury that we plan attic inspection time into every full-system cleaning for homes of this vintage. Call (806) 606-6902 for a written price that includes attic access.
Lake Quinsigamond keeps ambient humidity elevated through the summer in western Shrewsbury, and that moisture condenses on poorly insulated supply and return ducts. Inside the duct, that condensation creates conditions where mold and dust-mite accumulation accelerate. We see mold growth inside supply plenums in this part of Shrewsbury at a rate we do not see in drier neighboring towns. The cleaning removes the growth; the written photo record shows whether the duct insulation itself needs to be addressed to stop the condensation from returning.
The cleaning itself does not include sealing disconnected or separated sections. When we find a separation or collapse during a Shrewsbury HVAC cleaning, we document it with photos and quote the sealing, reconnection, or section replacement as a separate written line item before doing that work. Haven Standard Clause 1 applies: you get the number in writing before we touch the repair. If you want the sealing work done during the same visit, we can do that; we’ll just put it in writing first.
In our experience, the majority of Shrewsbury forced-air systems we open have never been professionally cleaned since the house was built. That means 25-40 years of accumulated dust, pet dander, construction debris, and, in many cases, insulation pulled in from disconnected attic runs. We find three-inch debris build-up at the first elbow in original systems with alarming regularity. That’s a documented, photographed condition, not an estimate based on age.
Our source-removal method follows NADCA protocol: negative-pressure extraction with HEPA filtration at the air handler, mechanical agitation of duct interior surfaces, and before-and-after documentation of every run. We don’t sell brush-only “cleaning” that stirs debris up and vacuums the visible part. In Shrewsbury’s older systems, that standard matters because the debris is deeper inside the runs than a guess-and-go visit would ever reach. Call (806) 606-6902 to see the written method in your quote.
