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 Malden
HVAC cleaning in Malden usually means one thing: a retrofit system in a pre-1940 wood-frame home that hasn’t been properly opened up in years. We know these houses. The triple-deckers off Pleasant Street and the two-families in Maplewood were built for radiators, not forced air. When ducts got shoehorned in decades later, they went through closets, wall chases, and ceiling cavities that were never designed for airflow. That means Malden systems collect debris faster and hide bigger problems than anything in a new suburb. Our crews work in Malden every week, and we document every duct run with before-and-after photos before we leave. Call us at (806) 606-6902, and we’ll give you a written price before any panel comes off.
Why CleanRun Air Duct Cleaning Is Malden’s Preferred HVAC Cleaning Company
CleanRun Air Duct Cleaning has been opening up Malden ductwork since 2013. Tomas Reyes leads a crew that knows what a 1970s Galvanized trunk looks like after forty years of plaster dust and pet hair, because we see it weekly in Edgeworth and Maplewood and Linden. Our customers in Malden don’t get a vague promise and a shop-vac. They get a camera inspection first, a written scope with a price attached, and a photo record of every run when the work is done. That record matters in a triple-decker. If you own one unit, you want proof the shared trunk actually got cleaned, not just the register in your kitchen.
Every Malden job is backed by the 365-Day Done Right Promise, in writing. If the work isn’t right, we make it right. That’s Haven Standard Clause 5, and it’s printed on your job record, not recited over the phone. Technicians are background-checked and uniformed, and they identify themselves by name before arrival. No subcontractors, no day labor. The person who shows up works for CleanRun.
Scheduling in Malden runs through our Boston office, and crews serve Malden locally. We answer the phone with a live person around the clock. When you call (806) 606-6902, you’ll talk to a human who can answer questions about your specific system, not a call center reading a script.
Our HVAC Cleaning Services in Malden
A full system clean in Malden typically covers the return side, the supply side, the blower, and the coil. In retrofit homes, that often means opening access panels that haven’t moved since the Carter administration. We’re set up for that. Here’s what we do most often in Malden.
Evaporator Coil Cleaning
The evaporator coil in a Malden retrofit system is rarely easy to reach. It’s often downstream of a return with no filter slot, which means years of debris have packed directly onto the fins. We remove the access panel, photograph the coil before anything happens, and then clean it with professional-grade coil cleaner followed by a rinse that won’t flood the blower housing. On a Maplewood three-decker, we regularly find a gray paste on the coil face: plaster dust from old lath walls, pet hair, and cooking grease pulled in from the kitchen return. After cleaning, the temperature drop across the coil typically improves enough that the system stops running long overtime cycles.
Air Handler Cleaning
The air handler is the workhorse of a Malden forced-air retrofit, and in older homes it’s often a 1970s or 80s unit mounted in a basement corner or a tight closet. We clean the blower wheel fins, the housing, the motor, and the drain pan. A blower wheel caked with dust can lose a third of its airflow capacity. In Malden’s triple-deckers, that means the third-floor unit gets almost no conditioned air while the first-floor tenant complains about noise. We clean it and photograph the difference. The photos go in your job record.
Condenser Cleaning
Malden summers are short but humid, and condensers sit under maple trees and along gravel driveways where they pick up leaves, pollen, and construction grit. A dirty condenser coil drives up head pressure and shortens compressor life. We clean the coil fins, straighten bent fins where needed, and clear the condensate line. If your condenser is a decade old and has never been opened, you’ll see the difference in the power bill within a billing cycle.
Coil Treatment
After cleaning, we apply a coil treatment that slows microbial growth and helps the coil shed moisture. In Malden’s older homes, where summer humidity sits inside poorly insulated duct sections, this matters. The treatment isn’t a wash-and-go spray. It’s applied after the coil is actually clean, because treating a dirty coil just seals the dirt in place. We photograph the coil before and after treatment as part of your record.

BeforeAfterMalden Retrofit Ductwork: What We Actually Find
Here’s what separates Malden from every other city we work in. In the 1970s and 80s, landlords and homeowners started converting radiator-heated triple-deckers and two-families to forced air. The ducts were not engineered. They were fitted into whatever space existed. Wall chases. Ceiling cavities. Closet corners. A supply trunk might run fine for six feet, then get crushed behind a stair stringer added during a later renovation. Flex duct gets kinked where it passes through a floor joist. Return air gets pulled from a hallway with no filter, and every dust particle in the building eventually lands on the evaporator coil.
In a Malden three-decker, one forced-air system frequently serves two or three rental units through shared ductwork. One neglected run circulates allergens through multiple households. A tenant on the third floor gets dust from the first-floor tenant’s cat. Cleaning one floor’s registers only treats part of the system. That’s why we camera-inspect the full trunk and branch layout before we start, and why we photograph every run after we finish. You need to see what was actually in there.
Our crew arrived at a Maplewood three-decker where a 1970s era air handler in the basement pushed air through original galvanized runs that had been extended with flex duct through closets on each floor. A camera inspection found the supply trunk pinched behind the second-floor stair stringer, and the evaporator coil was coated with a gray paste of plaster dust and pet hair. We set up negative pressure with HEPA filtration, disconnected the crushed section, agitated and source-removed debris from all supply and return ducts, then resealed the joints with mastic before reinstalling the air handler door. That’s a typical Malden job. The homeowner got photos of the crushed trunk and the clean coil, and a written record of exactly what we did.
Common HVAC Cleaning Problems We See in Malden Homes
- Crushed flex duct in wall chases. Retrofit flex runs get flattened where they pass through tight framing. The blockage is invisible from the register, so the blower works against high static pressure until the motor overheats. A camera inspection finds it in minutes.
- No filter slot at the return. Landlord-installed air handlers in older Malden homes often lack a proper filter housing. Debris bypasses the filter entirely and builds up on the evaporator coil and blower wheel. We clean the coil and recommend a filter slot installation as part of the scope.
- Shared ducts across rental units. In a two- or three-family, cleaning one floor’s registers only treats part of the system. The shared trunk still carries dust and mold spores from the lower runs to the upper floors. Partial cleanings lead to recurring complaints and callbacks. We clean the full shared system or we tell you it can’t be done properly without access.
- Mold and condensation in old flex sections. Malden’s summer humidity works its way into poorly insulated duct runs in attics and crawlspaces, creating condensation and mold on the inner liner. If the flex is older and the liner is compromised, cleaning won’t fix it. It needs replacement, which we’ll recommend with a written price.
Pricing for HVAC Cleaning in Malden, MA
A full HVAC cleaning in Malden runs between $450 and $900 for a single-family home with accessible ductwork. In a triple-decker or two-family with shared runs, the range is typically $700 to $1,400, because the system is larger and access coordination across units adds time. Evaporator coil cleaning as a standalone service in Malden costs $180 to $340. Air handler cleaning, including the blower wheel and housing, runs $150 to $280. Condenser cleaning is $120 to $220. Coil treatment after cleaning is $60 to $120. Those are written prices, not estimates. Haven Standard Clause 1 means you get a fixed price in writing before any work starts. No per-vent pricing. No bait-and-switch. The number on paper is the number on the invoice. Call (806) 606-6902 and we’ll put a price in front of you.
Bring a written estimate from another company and we’ll put our own number next to it in writing. That’s a Free Second Opinion, and it costs you nothing.
Trusted Brands We Service in Malden
Our crews work on systems from every major manufacturer installed in Malden homes, including Honeywell, Aprilaire, and Guardsman components. For cleaning equipment, we run Rotobrush and Nikro machines, the same professional-grade tools you can research independently before we arrive. In a Malden retrofit, brand matters less than access and condition. We’re more interested in whether the return has a filter slot and whether the flex run behind the second-floor closet is kinked. What we can tell you is which brand of air cleaner or dehumidifier makes sense for a specific Malden house, and we stock common replacement parts for Honeywell and Aprilaire equipment so we’re not waiting on a warehouse when your system needs a part.

FAQs - HVAC Cleaning in Malden
Shared ductwork in a triple-decker circulates air from multiple households through one trunk, so debris from every unit accumulates in the same runs. In a single-family home, one household’s dust load is spread across the system. In a three-family, three households’ dust, pet dander, and cooking particulates all converge in the same ducts. We typically recommend cleaning every 2 to 3 years for a Malden multi-family with shared runs, versus every 3 to 5 for a detached single-family. If you’ve never had the shared trunk cleaned and the building is pre-1940, schedule it now. The call to (806) 606-6902 is free.
First, the technician needs to determine whether any duct sections are wrapped in asbestos. Many Malden retrofits from the 1960s through the 80s used asbestos-wrapped insulation on ductwork, and disturbing those sections without proper handling is a serious health risk. We inspect before any agitation begins, and if asbestos is present, we’ll tell you in writing and recommend a licensed abatement contractor. Second, they need to check for disconnected or crushed runs. Third, they need to verify whether a filter slot exists at the return. Skipping these steps in an older Malden home means either missing a hidden hazard or cleaning a system that will clog again within a year.
No. A partial cleaning of shared ductwork treats only the portion of the system accessible from your unit. The shared trunk still carries dust and mold spores from the sealed-off sections to every register in the building. We won’t do a partial job and call it complete. If your tenants won’t allow access, we can provide a written letter explaining what needs to be cleaned and why, which often helps with coordination. We can also schedule the work for a time when access is available. The price stays the same either way, because we write it before we start.
Malden’s summer humidity condenses inside poorly insulated duct sections, especially in attic and crawlspace runs. That moisture supports mold growth on the inner liner of older flex duct, and in pre-1940 homes the liner is often already compromised from decades of thermal expansion. A post-summer cleaning removes the mold and debris that built up during the humid months, but if the liner is failing, cleaning won’t solve the problem. We’ll show you the camera footage and recommend replacement if the flex is past saving. That’s part of the documented record on every visit.
A clean filter doesn’t help if the ductwork downstream is crushed, kinked, or clogged. High static pressure from a pinched supply trunk or a collapsed flex section forces the blower motor to work harder than it was designed to, which drives up its temperature until the thermal overload trips. We see this constantly in Malden’s retrofitted systems, where duct runs pass through wall chases and stair stringers that were never meant to carry airflow. A camera inspection will find the blockage. Cleaning alone won’t fix a crushed section; it needs to be replaced and the joints resealed. Call (806) 606-6902 and we’ll find the actual cause, with a photo record to prove it.
