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 East Norwalk
HVAC cleaning in East Norwalk runs $450-$780 for a full system clean, including evaporator coil, blower, and air handler, with the coastal crawl-space homes near Norwalk Harbor typically landing at the higher end because of salt-air moisture and the extra time required to inspect flex duct integrity. We’re CleanRun Air Duct Cleaning, and we’ve worked the peninsula long enough to know that a system off East Avenue and one off Winfield Street can have completely different problems, even when both were built in 1958. Our HVAC Cleaning crew schedules all East Norwalk work directly from our Hartford office, and we’ll have a background-checked, uniformed technician at your door with a written price in hand before a single panel comes off. Call (806) 606-6902 to set a time.
Why CleanRun Air Duct Cleaning Is East Norwalk’s Preferred HVAC Cleaning Company
We founded CleanRun in 2013, and not once have we started a job without a written price delivered first. That’s not a policy subject to manager approval. That’s Haven Standard Clause 1, and it applies to every house on Gregory Boulevard, every condo along Cove Avenue, and every split-level near Fitch School the same way. Tomas Reyes, who leads our Connecticut operations, reviews every East Norwalk job file before the crew rolls, including the documented photo record from the prior visit. When a customer calls to ask what was actually done, we don’t describe it. We show them.
The coast changes things. We know the streets where lots sit at or below the 100-year flood elevation, and we know that a duct run in a crawl space off East Avenue will collect salt-corroded debris far faster than a system in Norwalk’s inland sections. That’s why our East Norwalk jobs always include a photo record of every run, before and after, as a standard deliverable. Not an add-on. Not a premium package. Every job since our first one in 2013 has ended with documentation the customer keeps.
Our East Norwalk customers routinely tell us the same thing: the written price got them to call, but the before-and-after photos of their own ducts are what convinced them the work was real. That’s the whole point. We don’t ask you to take our word. We hand you the evidence.
Our HVAC Cleaning Services in East Norwalk
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and does the actual cooling. In East Norwalk, the persistent marine humidity means this coil runs wet for most of the summer, and wet coils collect a film of salt, dust, and biological growth faster than the same coil would in Hartford or even inland Norwalk. We clean coils with trade-recognized equipment from Rotobrush and Nikro, and we photograph the coil before and after so you can see what was actually on it. On harbor-adjacent homes, we routinely find a gray-green residue that most homeowners assume is normal dust. It isn’t. It’s growth, and it’s reducing your system’s efficiency while pushing that air through your house.
Air Handler Cleaning
The air handler is the box that houses the blower and the coil, and in East Norwalk’s retrofitted 1940s-to-1960s homes, it’s often crammed into a closet, an attic kneewall, or a crawl space where access is tight and previous owners decided “good enough” was fine. That tight access is exactly why debris accumulates faster here. We remove the housing panels, clean the blower wheel, the coil, and the interior surfaces, and we check the integrity of the drain pan and condensate line, which corrode faster in salt air than inland. Then we photograph the finished interior. A clean air handler should look like a machine, not a biology experiment.
Blower Cleaning
A blower wheel caked with salt-laden dust doesn’t move air properly, and a blower that has to work harder pulls more energy and fails sooner. East Norwalk’s coastal air deposits a fine, slightly tacky film on blower vanes that ordinary vacuuming doesn’t fully lift. We use negative-pressure extraction to pull debris from each vane and the surrounding housing, and we run the blower, with the access panel off and the HEPA filtration running, before we photograph it. If the blower wheel is pitted from corrosion, we’ll tell you and show you the photo, so you can decide whether to replace it now or monitor it. No pressure. Just the evidence.
Condenser Cleaning
The condenser is the outdoor unit, and in East Norwalk it takes a beating from salt spray, fog, and the occasional nor’easter. Salt deposits on the coil fins reduce heat exchange and drive up your cooling bill. We clean the condenser coil, check the fins for damage, clear the surrounding area of vegetation, and verify refrigerant pressure is within manufacturer spec before we call the job done. That last step matters because a dirty condenser can mask a slow refrigerant leak, and we’d rather find it while the unit is already open than have you discover it during a July heat wave.

We service and clean systems from Carrier, Trane, Rheem, Lennox, and Goodman, along with components from Honeywell and Aprilaire. More to the point, we stock the replacement filters, UV lamps, and coil treatments these systems need, which means we’re not running back to a supply house when we’re already in your driveway. Our equipment roster includes Abatement Technologies HEPA filtration and Rotobrush cleaning systems, professional-grade tools you can look up independently before you ever agree to a price. If a competitor shows up with a shop vac and a fogger, that’s your signal to ask what the fogger is actually doing. More on that below.
Common HVAC Cleaning Problems We See in East Norwalk Homes
- Hurricane Sandy-era mold still in the ductwork. Homes that took on water in October 2012 often had mold colonize the duct interiors, especially in fiberglass-lined runs in crawl spaces. That was thirteen years ago. We still find it, and most owners never connected the dots because the smell faded even though the mold didn’t.
- Collapsed flex duct in crawl spaces. Repeated moisture cycles from flooding, fog, and humidity degrade the flexible duct sections common in this area’s retrofitted systems. When the flex collapses or detaches, your system pulls salt-laden, moldy air directly from the crawl space instead of from the return register.
- Salt-corroded fittings and registers. The close proximity to Long Island Sound means metal components corrode faster here than anywhere else in Fairfield County. We routinely find registers that have rusted to the point where they can’t be opened or closed properly, and blower housings with early pitting.
- Fogging-only “sanitizer” upsells that did nothing. We hear this a lot. A previous company fogged the ducts with an antimicrobial spray and charged extra for it, but skipped the actual extraction. The mold embedded in the fiberglass liner survived, and within weeks the problem was back. Fogging without source removal is a topical treatment for a structural problem.
Pricing for HVAC Cleaning in East Norwalk, CT
We quote one flat price per system, in writing, before any work starts. That’s Haven Standard Clause 1, and it means the number you sign off on is the number you pay. No per-vent pricing. No “discovered” problems that require a new number once the crew is already in your house. Here’s what East Norwalk homeowners can expect:
- Full HVAC clean (evaporator coil, blower, air handler, condenser): $450-$780, depending on system size, accessibility, and the condition of the duct runs.
- Coil-only clean: $180-$320.
- Blower-only clean: $150-$260.
- Coil treatment application: $90-$160, applied after a full extraction. We use it as a preventive step, not as a substitute for cleaning.
Systems in crawl spaces near the harbor, where access is tight and flex duct integrity needs checking, run at the higher end because the work takes longer and requires more inspection time. We’ll tell you the exact number before we start, and we’ll put it in writing. Call (806) 606-6902 to schedule; the estimate is free, and it’s a real number, not a teaser.

FAQs - HVAC Cleaning in East Norwalk
Because salt air and marine humidity create a chronically damp duct environment, and damp ducts grow biological films far faster than dry ones. Homes within walking distance of Norwalk Harbor are dealing with condensation inside the duct runs for most of the year, not just in summer. That moisture accelerates corrosion and gives mold and bacteria a surface to colonize. In our experience, harbor-adjacent systems benefit from cleaning every two to three years, while inland Connecticut systems can often go four to five. Call (806) 606-6902 and we’ll help you figure out which category your house falls into, based on what we actually find in the photo record.
No. Fogging only treats the surface it touches, and mold that colonized fiberglass duct liner or the interior of a collapsed flex run is not on the surface. It’s embedded. A fogger will leave that mold alive, and the first time the humidity spikes, it recolonizes. The only genuine treatment is source removal: physical extraction with negative pressure and HEPA filtration, followed by cleaning the interior surfaces, and only then applying a coil treatment if it makes sense. If a company wants to fog your ducts without first doing the extraction, they’re selling you a smell, not a solution. We’ll put our assessment in writing, with photos.
It includes a full inspection of the flex duct runs before and after cleaning, because on this peninsula, the flex duct is often the problem as much as the dust is. We check that runs are attached, that they’re the correct diameter, and that no water is pooling underneath them. Then we clean the evaporator coil, blower, air handler, and condenser with negative-pressure extraction and HEPA filtration. You get a photo record of every run, inside and out, before and after. That record is yours, and it’s the only way to actually verify the work happened. If a company won’t show you the inside of your ducts after they’re done, ask why.
Yes, and these are some of the homes that need it most. Many of East Norwalk’s 1940s-to-1960s colonials and cape cods started out with steam or hot-water radiators and later had forced-air central air retrofitted. Those retrofit ducts were often run through tight attic kneewalls or uninsulated crawl spaces, using whatever flexible duct could be squeezed into the existing structure. The result is often undersized runs with sharp bends, which trap debris faster than purpose-built systems and are more vulnerable to the moisture problems we described above. If your house has radiators and central air, treat the AC ductwork as a separate system that needs its own maintenance schedule.
If your house is in one of East Norwalk’s FEMA flood zones, particularly those streets closest to the harbor, and you know the house took on water during Sandy in October 2012, the safest assumption is that the ducts need to be looked at with a camera. Normal dust is gray and dry. Mold growth looks darker, often with a green or black tint, and it clings to the duct liner rather than brushing off. The only honest way to know is to look. We photograph the inside of every run before and after, so you’ll see exactly what’s there, and we’ll tell you whether it’s dust, mold, or both, no guessing.
