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 Stanwood
HVAC cleaning in Stanwood typically runs $425 – $785 per system, and most jobs are completed in a single visit lasting four to six hours. That’s the honest range before anyone steps inside your home, and it’s the number we hand you in writing before a single duct is touched. If you’re dealing with musty air, weak airflow from your registers, or coils that haven’t been cleaned since you moved in, call us at (737) 727-2314 and we’ll walk you through exactly what your system needs.
Our crews work throughout the Stillaguamish valley all year, from the neighborhoods off SR 532 up through the newer developments along Pioneer Highway. We know Stanwood homes because we’re in them every week, and we know what the local climate does to HVAC equipment. More on that below.
Why Cardinal Air Duct Cleaning Is Stanwood’s Preferred HVAC Cleaning Company
Stanwood homeowners call us because we run our business differently than the per-vent coupon shops. Every job gets a written price before work starts, a live trackable arrival window through the Relay Standard, and before-and-after photos of your own system. You see exactly what we cleaned because we document it, coil and duct by duct. No guessing whether the work actually happened.
We’re part of the Relay Home Co. family, founded 2005, and our techs are background-checked, uniformed, and arrive with professional-grade equipment: Rotobrush rotary agitation tools, Nikro HEPA vacuums, and Abatement Technologies containment units. Omar Haddad runs our Stanwood service area, and he holds every job to the 365-Day Done Right Promise: if the work isn’t right within a year, we return and correct it at no charge.
Every booking includes a written guarantee on repairs and a free second visit if a repair fails. Calls are answered by a live person around the clock, not a voicemail tree. That matters when you’re juggling work, kids, and a system that’s been wheezing for months.
Evaporator Coil Cleaning in Stanwood
Evaporator coil cleaning in Stanwood is the single most important HVAC service for the damp, cool air that settles in the Stillaguamish valley. The coil sits inside your air handler and pulls moisture out of the air as it cools. In Stanwood, that moisture often carries fine organic matter from the surrounding farmland and wetlands. The result is a coil matted with a damp, sticky film that reduces heat transfer, drives up energy use, and produces that musty smell homeowners notice when the blower kicks on. A typical coil cleaning in Stanwood runs $180 – $340 when bundled with full HVAC cleaning.
What Our Coil Cleaning Actually Involves
We access the air handler, remove the access panel, and inspect the coil with a camera before touching it. Then we apply a foaming coil cleaner, agitate the fin surface with soft brushes, and rinse with low pressure so the debris flows into our containment system rather than into your ductwork. If the coil is heavily impacted, we’ll pull it for a deeper clean. Either way, you get photos of the before and after.
Coil Treatment for Stanwood’s Damp Air
After cleaning, we apply an antimicrobial coil treatment that slows regrowth of the organic film Stanwood’s humidity encourages. It’s not a permanent fix, and no honest company will claim it is. But it does extend the interval between cleanings and keeps the musty odor from returning as quickly. Most Stanwood homes benefit from coil service every two to three years.
AC Duct Cleaning in Stanwood
AC duct cleaning in Stanwood means removing the accumulated dust, pet dander, and organic debris from your supply and return ducts, not just vacuuming the register openings. We use negative-pressure extraction, meaning the loosened debris travels straight into a HEPA-filtered vacuum instead of back into your living room. For an average Stanwood home with one furnace and four to six supply runs, full AC duct cleaning runs $425 – $785. We quote per system, never per vent.
When Stanwood Homes Really Need Duct Cleaning
You’ll know it’s time when you see dust accumulating quickly on furniture after the system runs, when airflow from certain registers is noticeably weaker than others, or when a musty smell lingers when the heat or AC cycles on. Homes near the Stillaguamish River or with mature landscaping tend to collect more organic matter in return ducts. If your home has been renovated recently, drywall dust is another reason to have the ducts cleaned: that fine powder settles in the system and recirculates for months.
The Camera Inspection First
We don’t clean blind. Before we start, we run a camera through the return duct, the supply trunk, and the air handler. In Stanwood, this often reveals buildup the homeowner couldn’t see and wouldn’t have known to ask about. Our tech was called to a home near the Stanwood-Camano YMCA off SR 532, where the homeowner complained of musty odors and reduced airflow. The camera inspection found the evaporator coil matted with a mix of dust and organic matter, likely from the valley’s damp air. After cleaning with Rotobrush tools and negative pressure, the airflow improved and the odor was gone, all documented with photos.
Trusted Brands We Service in Stanwood
We work on all major residential HVAC equipment found in Stanwood homes, from Carrier and Trane to Lennox, Rheem, and Goodman. We keep common filtration products from Honeywell and Aprilaire on our trucks, which means we can often replace a clogged media filter during the same visit. For homes with older ducting or tight crawlspaces, we use Abatement Technologies containment units to capture debris at the point of removal. Our HVAC Cleaning team carries these tools on every Stanwood job, not just the big ones, because the work should be done correctly the first time, for every house.
Common HVAC Cleaning Problems We See in Stanwood Homes
- Damp coil buildup from valley humidity. The Stillaguamish valley traps cool, moist air, especially from October through April. Condensation on the evaporator coil never fully dries, so dust sticks instead of blowing through. That film is what causes the musty smell most Stanwood homeowners describe.
- Debris accumulation in return ducts near entryways. Homes with mudrooms or doors opening directly to gravel driveways pull fine sediment into the return path. We see this most in the older neighborhoods around downtown and along Pioneer Highway, where homes sit close to unpaved lanes and working farmland.
- Pet dander and hair binding to blower wheels. Multiple-pet households in Stanwood generate enough dander to coat blower fan blades within eighteen to twenty-four months. A coated blower moves less air, works harder, and shortens motor life. Blower cleaning is included in our full HVAC cleaning, not priced as an add-on.
- Hidden buildup in the air handler cabinet. Even homes that have had ducts cleaned before often have an untouched air handler. That’s where the worst of it hides. We clean the air handler interior, the blower, and the coil as part of the system price, because cleaning ducts but skipping the handler solves only half the problem.
Pricing for HVAC Cleaning in Stanwood, WA
A full HVAC cleaning for a typical Stanwood home runs $425 – $785 per system. That includes the supply and return ducts, the air handler, blower, and evaporator coil. Condenser cleaning for the outdoor unit runs $120 – $190 as a separate service. Heat exchanger cleaning, when applicable, falls within the full-system range. We quote one flat price per system before work starts, and that number does not change at the door. The final invoice matches the written quote unless you approve additional work in writing first. Call (737) 727-2314 for a free estimate based on your home’s duct count and equipment type.
Here’s the thing about cheap per-vent pricing: it’s how companies hook you with a low number that multiplies fast. A four-bedroom Stanwood home might have fifteen to twenty vent openings. At $35 per vent, that’s $525 to $700 before they mention the coil, the blower, or the air handler. In other words, you’re paying the same as our full-system price for half the work. That’s why we quote per system, and why we show you photos of every component we cleaned.

FAQs About HVAC Cleaning in Stanwood
Every three to five years for most Stanwood homes, with the damp valley air pushing that closer to three years when pets are present or the home sits near the river or farmland. If you’ve never had the evaporator coil inspected and your system is more than five years old, the coil probably needs attention now. Call (737) 727-2314 and we’ll walk through your home’s specifics.
Per system, always. One flat price for the entire duct system, air handler, blower, and coil, written and agreed before we start. We don’t do per-vent pricing because it creates the exact surprise-invoice dynamic Stanwood homeowners tell us they’re tired of.
We start with a walkthrough and camera inspection of the return, supply trunk, air handler, and coil. Then we connect a negative-pressure vacuum, clean each register run, agitate the main trunk with Rotobrush tools, clean the blower and coil, and finish with an antimicrobial treatment if needed. You get before-and-after photos and a digital invoice you can pay from your phone. The whole job typically takes four to six hours.
Yes. Evaporator coil cleaning is included in our full HVAC cleaning price for Stanwood homes. It’s not an optional add-on because skipping it leaves the most important component of your system untouched. If the coil is heavily impacted and requires removal for deep cleaning, we’ll show you the camera images and agree on the additional cost before proceeding.
We don’t promise same-day service because proper HVAC cleaning takes four to six hours when done to NADCA standards. Rushing the job means incomplete negative-pressure setup and skipped steps. We schedule within a few days to a week in most cases, and you get a live trackable arrival window. Call (737) 727-2314 to check current availability for your area of Stanwood.
