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 Cambridge
HVAC cleaning in Cambridge means working inside buildings that were never designed for forced air. The pre-WWII triple-deckers, converted Victorians, and early apartment blocks that define East Cambridge, Cambridgeport, and The Port were built for steam radiators. Every duct run in those buildings is a retrofit, and every retrofit creates the same problems: sharp bends, undersized plenums, and access points buried inside finished ceilings. Our crews know where those access points hide, because we’ve cut them open and documented what we found in buildings across Cambridge for more than a decade.
When you call CleanRun at (806) 606-6902, you get a written price before any panel comes off, a camera record of every duct run before and after, and a crew that has already worked buildings just like yours. That’s the whole point.
Why CleanRun Air Duct Cleaning Is Cambridge’s Preferred HVAC Cleaning Company
Run a search for HVAC Cleaning in Cambridge and you’ll find plenty of companies that will quote you a low number over the phone and then discover “complications” once the truck is parked. We don’t do that. Haven Standard Clause 1 says a written price is delivered before any work starts, every time, no exceptions. That price covers the full scope, and if the camera finds something the estimate didn’t anticipate, we show you the footage before we ask for a decision.
Cambridge customers call us specifically because our documented photo record ends the guesswork. After every job, you get before-and-after images of each duct run, the blower, the coil, and the plenum. You can see the debris we removed, because we photographed it where it sat. That’s not something most HVAC cleaning companies in Cambridge offer, and it’s the reason homeowners and condo association boards keep our number on file.
We also know how Cambridge works on a practical level. That means we schedule apartment and condo work around building access rules, we plan for street parking restrictions in The Port and Cambridgeport, and we don’t bring a truck-mounted vacuum into a triple-decker if there’s no space for it at the curb. We bring the right equipment for the building, not the other way around.
Our HVAC Cleaning Services in Cambridge
Evaporator Coil Cleaning
The evaporator coil is where condensation forms, and in Cambridge’s humidity, that coil is damp more often than it’s dry. Add the drywall dust and cooking grease that circulate through retrofit ducts in older buildings, and the coil becomes a paste trap. That buildup insulates the coil, cuts cooling capacity, and forces the compressor to run longer. We clean the coil by hand where access allows, then treat it so condensation doesn’t immediately re-adhere dirt to the fins. This matters more in Cambridge than in drier inland towns.
Blower Cleaning
The blower motor moves every cubic foot of air your system heats or cools. In Cambridge buildings with shared return ducts or long retrofit runs, the blower pulls air across whatever has accumulated in the duct interior, and fine particulate cakes onto the fan blades and motor housing. That reduces airflow, shortens motor life, and in some cases causes the blower to go out of balance and start making noise. Our techs pull the blower, clean the wheel and housing, and photograph the before and after. You don’t guess whether it was done. You look at the picture.
Condenser Cleaning
Condensers in Cambridge live in some tight places: flat roofs on converted Victorians, narrow side yards between triple-deckers, or enclosed wells behind rented units. Debris builds up faster when the unit sits near a shared alley or a busy bus route. We clear the coil, straighten fins where needed, and check the refrigerant line for signs of wear. We can also photograph the coil depth before we start, so you can see what was blocking airflow.
Air Handler Cleaning
Air handlers in Cambridge’s retrofit installations are often shoehorned into closets, crawl spaces, or attic knee walls. That makes them easy to miss during routine maintenance, and once the housing fills with dust, every room the air handler serves receives filtered air through that layer of debris. We clean the cabinet interior, the drain pan, and the return side of the unit, then run the system to verify airflow is moving through a clean pass. For condo units in buildings with shared mechanical spaces, we coordinate with building management so the work doesn’t interrupt neighbors.

BeforeAfterTrusted Brands We Service in Cambridge
Our equipment roster includes professional-grade systems from Rotobrush, Nikro, and Abatement Technologies, and we use Guardsman products where a surface is being treated. We service and clean components from the major manufacturers Cambridge homeowners already have installed: Carrier, Trane, Rheem, Goodman, Bryant, and Mitsubishi among others. Because Cambridge’s housing stock includes so many retrofits, we keep a range of standard-size filters, gaskets, and coil cleaning chemistry on hand so we don’t have to leave a job halfway through and come back.
Common HVAC Cleaning Problems We See in Cambridge Homes
After years of documenting duct interiors in Cambridge buildings, we can predict what a camera inspection will find before we even look. The list below is what actually shows up.
- Retrofit ductwork with sharp bends. Cambridge’s triple-deckers and converted Victorians were built for radiators. When forced air was retrofitted, installers ran ducts around existing framing and plumbing. The result is sharp turns, narrow plenums, and dead spots where debris settles and can’t be dislodged by a standard brush. A standard residential tool can tear flex duct in these configurations. We inspect first, then choose the agitation method.
- Shared dryer vents in triple-decker stacks. When one unit’s dryer vent clogs, the pressure backs up into the neighboring units before anyone in the building notices. We have seen entire three-story vertical stacks where the bottom unit’s lint was the culprit for reduced airflow on all three floors. The remedy is cleaning the full stack, not just the one unit that called us.
- Debris loads from multiple tenants. In rental corridors near Harvard and MIT, turnover is constant. Units get renovated while the HVAC keeps running, which pulls drywall dust, paint overspray, and a rotating cast of pet dander and cooking grease into the system. After five or six lease cycles, a blower wheel can carry a quarter inch of compacted material. That’s not hyperbole; it’s a photo file on our camera.
- Missing access points. Some retrofit ductwork in Cambridge has no cleanout access at all. The installer buried the duct run inside a finished ceiling and left no way to visually inspect it. The first thing our crew does is locate the duct path and determine if an access point exists or needs to be created. Skipping camera inspection on these jobs means trying to clean a duct blind, and no honest technician would claim to know what’s inside without footage.
Pricing for HVAC Cleaning in Cambridge, MA
In Cambridge, a full HVAC cleaning on a single-family home or one unit in a multi-family building typically runs $450 to $950, depending on the number of duct runs, the number of stories, and access difficulty. That’s an honest whole-system range. We don’t use per-vent pricing and we don’t advertise a teaser that becomes something else once the van arrives. The written price you get before work starts is the price you pay, under Haven Standard Clause 1.
For a Cambridge triple-decker with three separate systems, the total project cost usually falls between $1,200 and $2,400 depending on whether we’re cleaning evaporator coils and blowers in each unit. A converted Victorian with hidden ductwork and multiple access points will land at the higher end of the range. Condenser-only cleaning on a standard rooftop or yard unit runs $150 to $300, and blower-only cleaning is typically $180 to $350. Evaporator coil cleaning runs $200 to $450 depending on accessibility. We can give you one written price for the entire job before anything begins.

FAQs - HVAC Cleaning in Cambridge
Because the ductwork was retrofitted around existing framing and party walls, so no single access point exposes the full run. A triple-decker’s supply trunk may split inside a finished ceiling, run through an old chimney chase, then branch again behind a stairwell wall. Our techs use a camera to map the run and determine how many access points are needed to clean the full length. We create access points where none exist, and we photograph everything we access. Call (806) 606-6902 and we’ll explain what your building needs before any work starts.
Yes. We use portable negative-pressure equipment from Rotobrush and Nikro that moves in a wheeled cart and fits through a standard Cambridge doorway. For buildings with no driveway, we park legally at the curb and wheel the equipment inside. The suction is comparable to what a truck-mounted unit produces, and the HEPA filtration is part of the portable setup. If your building has tight hallways or narrow stairwells, we plan for that ahead of time, not when we arrive.
We clean from the bottom access point upward using a rotary brush sized to the stack diameter, then verify with a camera that the full vertical run is clear. In a shared stack, the bottom unit’s lint often compacts and blocks the common riser, which backs up every unit above it. That means the repair can’t be solved by cleaning one unit’s vent; the whole stack has to be cleared. We coordinate that with the building owner or condo manager so the work is comprehensive and documented. Call (806) 606-6902 and we’ll scope the whole stack, not just one floor.
We create one, and we photograph the before and after so you can see exactly where it was placed and why. In a converted Victorian, duct runs often sit inside finished ceilings, old servant stairways, or behind built-in cabinetry. The original installers didn’t leave access. If we can’t reach the full run through an existing register or plenum, we cut a cleanout, clean the duct, and seal it. The photo record documents that the job was done through confirmed access, not through guesswork. You’ll see the hole we cut and the sealing we applied.
Because the systems have accumulated material from multiple tenants over multiple lease cycles without routine cleaning between them. Units near campus turn over every September, and renovations are often done with the HVAC running. The ducts carry drywall dust from unit renovations, cooking grease from years of shared kitchens, and sometimes rodent nesting material pulled in through gaps where retrofit ducts pass through uninsulated basement ceilings. Cleaning a system with that level of accumulation takes more passes, more agitation, and more camera verification than a single-family home in Belmont. The written price we give you accounts for the true condition of the system, not a generic per-vent rate that will get revised once we open a panel. Call (806) 606-6902 and we’ll give you one written price before anything starts.
