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 Bellevue
HVAC cleaning in Bellevue runs $325 – $680 for a standard single-system home, and most jobs are completed in three to five hours. The work should include the evaporator coil, blower motor, supply and return ducts, and the air handler cabinet, because that’s where Bellevue’s damp, mild climate lets dust and biological growth accumulate. If you’ve never had the coil or blower cleaned, that’s the first place we look. Call (737) 727-2314 and we’ll give you a written price before a single panel comes off.
We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005. Our crews work throughout Bellevue weekly, from Crossroads to Somerset to Enatai, so we know what this city’s housing stock throws at us. Omar Haddad leads our team, and every booking comes with The Relay Standard: a live trackable arrival window, before-and-after photo proof, and a digital invoice you can pay from your phone.
Why Cardinal Air Duct Cleaning Is Bellevue’s Preferred HVAC Cleaning Company
We’re not a general handyman service that happens to own a shop vac. We run Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units on every job. That equipment matters because Bellevue’s tight duct runs and multi-zone systems need actual source removal, not just air blowing. Our technicians are background-checked, uniformed, and you’ll know their name before they ring the bell.
Bellevue customers call us after trying the discount route and finding out the hard way what “per vent” pricing really means. We quote one flat price per system, in writing, before any work starts. If the technician finds something unexpected mid-job, you hear about it before we touch it, not after. That’s the 365-Day Done Right Promise: if the work isn’t right within a full year, we come back and correct it at no charge. No fine print, no hoops.
Our HVAC Cleaning team has worked in nearly every Bellevue neighborhood, and we answer the phone with a live person 24/7. Not a call center script, not a voicemail loop. You call, a human answers, and we schedule around your day.
AC Coil Cleaning in Bellevue
AC Coil Cleaning in Bellevue is the single highest-impact service we perform, because the evaporator coil in your air handler is where cold refrigerant meets the warm air from your home, and that temperature difference pulls moisture out of the air. In Bellevue’s Puget Sound climate, that moisture rarely gets a chance to fully dry between cycles, especially when the system runs in fan-on mode year-round. The result is a wet coil surface that catches dust like flypaper, and within two or three years that dust becomes a damp mat that blocks airflow and feeds microbial growth.
A coil cleaning on a standard Bellevue home runs $180 – $320 as part of a full system cleaning. We pull the access panel, photograph the coil before and after, and use a condenser-safe foaming cleaner that breaks down the organic film without eating the aluminum fins. Then we rinse and vacuum the wash water with a HEPA-rated extractor so it doesn’t end up in the drain pan or the ducts below.
When Bellevue Homeowners Need Coil Cleaning
If your system runs constantly but the upstairs is still five degrees warmer than the downstairs, or if your electric bill crept up without a rate change, your coil is probably insulated in dust. Bellevue homes with pets, recent renovation work, or systems that haven’t been opened in five-plus years are the most common calls we get. The fix is straightforward, and you’ll see the difference in the before-and-after photos before we leave.
Coil Treatment and Protection
After cleaning, we apply a coil treatment that slows re-soiling. In Bellevue’s damp climate, this step matters twice as much as it does in drier cities. The treatment is included in the coil cleaning price, not billed as a mystery add-on.
AC Cleaning in Bellevue
AC Cleaning in Bellevue means cleaning the entire air handling loop, not just the registers. That includes the evaporator coil, the blower wheel and motor assembly, the return air plenum, and the supply trunk lines. In Bellevue’s mid-century ramblers around Lake Hills and Crossroads, we frequently find original flex duct that’s disconnected at joints in the crawlspace, pulling humid, unconditioned air directly into the system. That’s not a cleaning problem; that’s a system integrity problem, and we address it during the same visit.
A full AC cleaning on a single-system Bellevue home typically runs $325 – $680 depending on system size, number of zones, and how much debris has accumulated. That’s one flat price for the entire system, agreed before we start. We never charge per vent, and we never leave without showing you photographic proof of the duct walls, coil, and blower wheel, inside and out before, and after.
Blower Cleaning and Airflow Restoration
The blower wheel is the part we find most neglected in Bellevue homes. Because the mild climate means systems run at low load almost constantly, dust collects on the curved blades and throws the wheel out of balance. That shortens motor life and cuts airflow. We remove the blower assembly, clean each blade by hand, and reinstall it with the motor mounts checked and tightened.
Full-System Air Handler Cleaning
The air handler cabinet is the box that houses the coil, blower, and filter. In newer downtown Bellevue high-rises and BelRed condos, that cabinet is often tucked behind a closet door with almost no clearance. Our technicians carry compact tools for exactly those spaces. The cabinet gets vacuumed and wiped down with an antimicrobial cleaner approved for HVAC use, and the condensate drain line is cleared and flushed so it doesn’t back up into the pan.
Trusted Brands We Service in Bellevue
We service and clean systems from every major manufacturer, and we stock replacement Aprilaire media filters and Guardsman treatment products on our trucks so Bellevue customers aren’t waiting on a parts run. Whether you have a Mitsubishi ductless system, a Carrier split, a Trane air handler, or a Goodman furnace-and-coil combo, our process is the same: inspect, photograph, clean, document. The Rotobrush system handles round and rectangular duct, and the Nikro HEPA extractor keeps loosened debris moving in one direction only, out of your house. That’s negative-pressure extraction, which simply means the dust goes into the vacuum, not back into your living room.
Common HVAC Cleaning Problems We See in Bellevue Homes
- Musty odor from floor registers in split-levels and ramblers: Bellevue homes built in the 1960s and 1970s often have flex duct in the crawlspace that’s disconnected or torn. The system starts pulling crawlspace air, which is damp and smells like earth, and pushes it through every room. Duct cleaning alone won’t fix it; the runs have to be reconnected and sealed first.
- Continuous blower use in tight, newer construction: Downtown and BelRed homes are sealed tight for energy efficiency, which means the blower runs almost constantly just to move air. That’s good for air quality, but it also means dust never settles, it just keeps circulating through the coil and blower wheel. Coil cleaning is the fix for the smell and the inefficiency.
- Multi-zone systems with one neglected return trunk: Many Bellevue homes have two air handlers or zoned dampers, and a cheap per-vent cleaning will skip the second-story supply trunk entirely. We clean the entire system, both zones, as one flat price.
- Overdue Aprilaire media cabinet replacements: If the media filter in your cabinet hasn’t been changed in a year or more, the pressure drop across the filter chokes airflow and pulls more unfiltered air through gaps. We replace the Aprilaire media during the cleaning if your filter is ready for it.
Pricing for HVAC Cleaning in Bellevue, WA
A standard HVAC cleaning in Bellevue runs $325 – $680 for one full system. Coil-only cleaning runs $180 – $320. Full-system cleaning with duct reconnection, blower removal and cleaning, coil treatment, and new Aprilaire media (if due) heads toward the upper end. Homes with two air handlers or long commercial-style trunk runs in larger Bellevue properties will see pricing adjusted up accordingly, and you’ll see that number in writing before we start.
We don’t do per-vent pricing. Ever. Per-vent pricing is how a cheap quote becomes a $900 invoice once the technician counts registers and returns. Our quote is one number, per system, written down before a single panel is opened. Call (737) 727-2314 for a free estimate, and we’ll tell you the price over the phone or in person, whichever you prefer.

FAQs About HVAC Cleaning in Bellevue
Every four to seven years for most Bellevue homes, with two exceptions: if you have pets that shed heavily or you’ve done recent remodeling, every three to four years is more realistic. The honest answer is that many homes in Bellevue go too long without coil and blower cleaning because the ducts look clean at the register, but the coil is caked. If you can’t remember the last time the system was opened up, it’s time. Call (737) 727-2314 and we’ll inspect honestly, no pressure.
Per system, one flat price, always. Per-vent pricing is how discount operators make their money, and it punishes Bellevue homeowners with larger homes and more registers. We give you one written price before work starts, and it doesn’t change at the door.
Yes, every single time. You’ll see photos of the duct walls, coil, and blower wheel taken from inside the system, before and after, on a tablet before we leave. If a company won’t show you photographic proof of the interior of your own ducts, they can’t prove the work happened. We can, and we do.
Nearly always, the evaporator coil has a layer of biological growth on it, and the blower wheel is coated in dust that holds moisture. Bellevue’s mild, damp climate means the coil rarely dries out fully, and when the blower runs constantly, that damp biological material sends odor through the supply registers. Coil cleaning and blower cleaning solve the smell, not the ducts alone. A quick inspection call confirms the source.
Yes. We regularly clean systems in downtown Bellevue towers and BelRed condominiums. The equipment is compact enough for closet-mounted air handlers, and we coordinate with building management when access to a mechanical room is required. The same flat pricing and photo documentation applies.
