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 Alderwood Manor’s Preferred HVAC Cleaning Company
Alderwood Manor sits in unincorporated Snohomish County, where most homes are heated by forced-air furnaces or heat pumps that run through damp, cool months. Duct systems here collect fine dust and debris rather than the heavy allergens of drier climates, and the real issue is often a blower motor or air handler pulling from a leaky return rather than the supply runs themselves. Our HVAC Cleaning team knows this because we work inside these homes every week.
We’re held to The Relay Visibility Guarantee on every booking: you get a live trackable arrival time, before-and-after photos of your own ducts, and a digital invoice you can pay from a link. No other duct cleaner in Alderwood Manor operates that way. Our technicians are background-checked, arrive in uniform, and you’ll know the tech’s name before they knock on your door.
Omar Haddad leads the team, and he’s built the Alderwood Manor operation around one rule: a written price before a single duct is touched. That’s not a promotion. It’s how every job runs, including yours.
AC Vent Cleaning in Alderwood Manor
AC vent cleaning in Alderwood Manor is the process of removing accumulated dust, hair, and debris from the supply and return registers plus the duct runs that connect them. In this area’s damp-cool climate, those runs trap fine particulate that then recirculates every time your furnace or heat pump kicks on. You’ll notice it as a thin film of dust settling on furniture within a day or two of cleaning, or as a musty smell when the blower first starts.
Most Alderwood Manor homeowners need this when they see dust around the registers themselves, when someone in the house has persistent allergy symptoms, or after any remodel that filled the air with drywall dust. The job typically runs $180 – $320 for a full supply and return cleaning in a standard three-bedroom home. We never charge per vent; you get one flat price per system in writing before we start.
Camera Inspection Before Anything Else
We run a camera through the supply and return trunks before we quote. Alderwood Manor’s older split-levels often have disconnected or leaky returns pulling crawlspace or attic air, and a camera shows that in minutes. If the supply runs are clean but the return is pulling from a gap, you should know that before paying for a cleaning that won’t fix the actual problem.
Negative Pressure and HEPA Extraction
We don’t blow debris from one room into another. We use negative-pressure extraction from Nikro HEPA vacuums, meaning loosened debris goes straight into a sealed container, not back into your living room. The process is quiet enough that you can keep working from home while we’re in the house.
Furnace Duct Cleaning in Alderwood Manor
Furnace duct cleaning in Alderwood Manor focuses on the full forced-air path: the cold air returns, the furnace blower compartment, the heat exchanger area, and the supply runs back into the rooms. Here in Snohomish County, furnaces run from October into April, and that constant operation builds a fine, packed layer of dust inside the trunk lines that simple register vacuuming never reaches. A full furnace duct cleaning on an average Alderwood Manor home runs $420 – $680.
When should you act? If your furnace has run through a full heating season since the last cleaning, if your filter clogs faster than normal, or if you’ve had pets or a remodel recently. Homes near 164th St SW and the surrounding neighborhoods with mature landscaping also contend with more organic debris – pollen, leaf particles, and fine soil that settles into duct works over time.
Blower Motor and Air Handler Attention
Fine dust sticks to the blower wheel and settles inside the air handler compartment, and most generic cleanings skip that step entirely. We clean the blower wheel, blower housing, and the air handler cabinet as part of the per-system price. Skip that, and your freshly cleaned ducts are recirculating the same dust from the motor within a week.
Heat Exchanger and Coil Surface Care
We don’t use water or solvents on heat exchangers or coils unless the manufacturer specifically calls for it. Instead, we use dry agitation and HEPA extraction to lift and remove surface debris without risking corrosion or mold growth. For Alderwood Manor’s forced-air furnaces, that’s the difference between a clean system and a future repair bill.
Trusted Brands We Service in Alderwood Manor
We service and clean systems built around brands common across Alderwood Manor: Honeywell, Aprilaire, Guardsman, and others. If you have an Aprilaire filter cabinet or a Guardsman UV system mounted on your ductwork, our technicians know how to clean around it properly without damaging the components. We carry the common replacement filters and media in our service vehicles, so most Alderwood Manor customers don’t wait days for a part. Our equipment is professional-grade: Rotobrush for rotary brushing, Nikro for HEPA extraction, and Abatement Technologies for containment when job conditions call for it.
Common HVAC Cleaning Problems We See in Alderwood Manor Homes
- Leaky returns pulling crawlspace air. We see this constantly in Alderwood Manor’s older split-levels and ramblers. A disconnected return duct means your blower is sucking unfiltered crawlspace air into every room, and no register cleaning can fix that.
- Blower compartments full of fine dust. Damp air plus constant furnace operation packs dust tight around the blower wheel. Standard cleanings ignore this area, so the dust recirculates within days. We open, clean, and photograph the blower compartment on every job.
- Per-vent pricing that pushes rushed work. Techs priced per vent have every incentive to move fast and skip the trunk lines where debris actually settles in Alderwood Manor homes. We quote per system, so the trunk lines, returns, and air handler all get the same attention as the registers you can see.
- Missing proof of the work. You shouldn’t have to take anyone’s word that the ducts were cleaned. We deliver before-and-after photos of your own ductwork on every job, taken during the camera inspection and again after extraction.
Pricing for HVAC Cleaning in Alderwood Manor, WA
A typical whole-system HVAC Cleaning in Alderwood Manor runs $380 – $680, depending on the number of systems, the size of the duct network, and whether there’s a second return or a crawlspace-mounted air handler. AC vent cleaning alone sits at $180 – $320 for a standard three-bedroom home. Furnace duct cleaning with full blower and air handler attention runs $420 – $680. Every quote is one flat price per system, agreed in writing before we open a single panel.
You will not get a per-vent price from us. That pricing model punishes thorough work and rewards skipping the parts of the system that matter most in Alderwood Manor’s housing stock. Call (737) 727-2314 for an exact quote. Estimates are free.

FAQs About HVAC Cleaning in Alderwood Manor
Every 3 to 5 years for most Alderwood Manor homes, and more often if you have pets, someone with allergies, or you’ve just finished a remodel. The damp-cool climate here means ducts collect fine dust slowly rather than heavy debris quickly, so annual cleaning is rarely warranted. If your home is on a crawlspace and the returns have never been inspected, start there. Call (737) 727-2314 and we’ll help you decide honestly whether cleaning is needed at all.
Flat price per system, always. Per-vent pricing creates the wrong incentive for a technician to rush through the registers and skip the trunk lines, returns, and blower where Alderwood Manor homes actually collect debris. Your written price covers the entire system: supply runs, returns, air handler, blower, and a camera inspection. That price is handed to you before any work begins.
Yes. Every Alderwood Manor job includes before-and-after photos of your own ductwork, taken with a camera inspection before we start and again after extraction. You’ll see the condition of the trunks, the returns, and the blower compartment, not stock photos from another house somewhere. This is part of The Relay Standard, and it’s non-negotiable.
Negative-pressure extraction means the entire duct system is placed under suction while agitation tools loosen debris. The loosened material moves toward the vacuum, not out into your rooms. We run this with Nikro HEPA filtration so the exhausted air is clean. In Alderwood Manor’s split-levels, where furnaces often sit in tight closets, this method keeps the workspace clean and the house livable during the job.
We schedule most Alderwood Manor jobs within a few days, and we won’t promise a same-visit slot that we can’t actually hold. A live person answers the phone 24/7, so you’ll get a real arrival window you can track from your phone, not a four-hour guess. Call (737) 727-2314 and we’ll get you on the schedule with a written price before the tech arrives.
If you’re in Alderwood Manor and want an HVAC cleaning that shows you the work, gives you a flat per-system price, and doesn’t disappear after the invoice is paid, call us. We’re Cardinal Air Duct Cleaning, and the number is (737) 727-2314.
