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.

Why Cardinal Air Duct Cleaning Is Thompsonville’s Preferred HVAC Cleaning Company
Thompsonville isn’t a suburb with cookie-cutter four-bedroom colonials. It’s a former carpet-mill village where houses were built fast, tight, and a century ago. That shapes how we work here. Omar Haddad runs our crews with a rule that every job starts the same way: map the system, photograph the registers, and hand you a written flat price before we open a single panel. The HVAC Cleaning team has worked enough mill-era houses off Main Street and Pearl Street to know that two identical-looking Capes can have completely different ductwork once you actually look inside.
We answer the phone at (737) 727-2314 with a live person, not a voicemail tree. You’ll know your technician’s name before they arrive. They show up in uniform, background-checked, with Rotobrush agitation tools, Nikro HEPA vacuums, and Abatement Technologies containment units in the van. The work is backstopped by the 365-Day Done Right Promise: if it isn’t right within a full year, we return and correct it at no charge. That applies to every job, no exceptions.
Evaporator Coil Cleaning in Thompsonville
Evaporator coil cleaning in a Thompsonville house usually means the coil sits in an air handler that was shoehorned into a basement corner or a closet never designed for mechanical equipment. Lint, pet hair, and a century’s worth of plaster dust get pulled across that coil every time the blower runs. A fouled coil makes the system work harder, raises your electric bill, and shortens compressor life. For most Thompsonville homes, evaporator coil cleaning runs $180 to $260 as part of a full HVAC clean.
How the Coil Gets Cleaned
We pull the access panel, photograph the coil before touching anything, then apply a foaming coil cleaner that breaks down the bonded film of dust and grime. After the dwell time, we rinse with low pressure so the fins don’t bend. Photos before and after go to your phone.
When Thompsonville Homeowners Need It
If your AC has been short-cycling, if the air coming out of the registers feels weak, or if the system froze up last summer, the coil is the first thing we check. It’s also the part most often skipped by companies that only vacuum the ducts and call it done.
AC Duct Cleaning in Thompsonville
AC duct cleaning in Thompsonville is a different animal than in newer developments. The original duct runs were retrofitted into plaster walls, not built as sealed systems. We routinely find returns that pull from unheated basements, mixed trunk sizes that no two houses share, and branch runs that dead-end in wall cavities. That’s why we never quote per vent over the phone. A full AC duct cleaning for a typical Thompsonville home runs $420 to $680, mapped and priced per system before we start.
Negative-Pressure Extraction, Explained
We seal off the supply and return openings and run a HEPA-rated vacuum that keeps the system under negative pressure while we agitate. That means the loosened debris goes straight into the vacuum, not back into your living room. Skipping this step on 1920s plaster-and-lath chases is how dust ends up dumped back through the registers.
Why Camera Inspection Comes First
Before we clean, we run a camera down the trunks and branch lines. In Thompsonville, that step catches things like collapsed sections, disconnected joints, and runs that were never connected to the plenum in the first place. You get the footage. You decide what you want done about it.
Trusted Brands We Service in Thompsonville
We work on all major equipment brands across Thompsonville, from older Carrier and Trane systems in the mill conversions to newer Rheem and Goodman units in the renovations along the river. Because we clean rather than replace, brand doesn’t change the price much. What matters is access, coil condition, and how much contamination is in the trunk. We stock Guardsman coil treatments and Aprilaire filtration media on the vans, so when your air handler needs a filter upgrade or a coil treatment after the clean, we don’t have to schedule a return trip.
Common HVAC Cleaning Problems We See in Thompsonville Homes
- Retrofitted duct runs in plaster walls. Most mill houses were never designed for forced air. The trunks run through chases that were cut after the fact, which means gaps, disconnected joints, and returns that pull unconditioned air from basements and wall cavities.
- Lint bypassing loose filter frames. On a call near the Enfield town line, our tech pulled a supply run off a 1920s mill-house air handler and found the blower motor caked in lint that had been bypassing a loose filter frame for years, with the return side pulling basement air straight off old stone. We ran agitation tools and a camera inspection down the trunks, cleaned the evaporator coil, and handed the homeowner side-by-side before-and-after photos of their own duct interior before we packed up the Rotobrush.
- Basement moisture and mold bloom. Stone foundations and high water tables along the Connecticut River mean basement air is humid. When unsealed returns pull that air into the system, you get musty smells from the vents and biological growth on coils and in trunk lines.
- Dead-end branch runs. We frequently see branch ducts that serve one register and were never properly connected at the plenum. They fill with dust over decades and then blow it into the room every time the blower kicks on.
Pricing for HVAC Cleaning in Thompsonville, CT
A full HVAC cleaning in Thompsonville typically runs $420 to $680 for the whole system. Evaporator coil cleaning as a standalone job runs $180 to $260. Blower cleaning runs $120 to $190. The variable is system size: how many returns, how many supply runs, and how much access the old chases allow. We hand you a written flat price per system before any work starts. If the ductwork is short, simple, and clean, the price lands at the lower end. If we’re mapping six returns and twenty registers across three floors of a mill conversion, it lands higher. Call (737) 727-2314 and we’ll talk through what your house actually has.

FAQs About HVAC Cleaning in Thompsonville
Every 3 to 5 years for most Thompsonville houses. Mill-era homes with retrofitted ductwork and basement returns may need cleaning more often, especially if you have pets or the original filter frames are loose. If the system was cleaned properly and the filters are changed regularly, pushing beyond 5 years is often fine. Call (737) 727-2314 and we’ll give you an honest read based on your house, not a blanket schedule.

Because you can’t see inside your own walls. Every HVAC cleaning we do in Thompsonville includes camera inspection footage and before-and-after photos of the inside of your ducts, the coil, and the blower. The photos prove the work happened and show you exactly what we removed. It’s part of The Relay Standard on every booking.
