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 Redmond
HVAC cleaning in Redmond involves more than vacuuming out a return vent. In this city, built out during Microsoft’s explosive growth years, the work usually means opening ducts installed between 1985 and 1999 and finding out exactly what’s inside them. Flexible ductwork has a design life of about 25 years. Most of Redmond’s ranches and two-story homes on Education Hill, Bear Creek, and Overlake are now 10 years past that. We bring a camera and a written price before any panel comes off. Here’s what that means for your HVAC system in Redmond, WA, and what it costs to fix what we find. Call (806) 606-6902 for a written estimate.
Why CleanRun Air Duct Cleaning Is Redmond’s Preferred HVAC Cleaning Company
CleanRun has held one position since 2013: every job starts with a written price, and every job ends with a photo record of the inside of your ductwork. That’s not a slogan. It’s Haven Standard Clause 1 and it applies to every HVAC cleaning we do in Redmond. No technician opens a plenum or pulls a register before you’ve seen the number and agreed to it.
Redmond homeowners call us because they want to know what the tech saw, not how the tech felt about it. We photograph the blower wheel before cleaning and after. We photograph the evaporator coil before cleaning and after. We photograph the inside of the supply trunk and the return drop. You receive those images as part of the standard job record, along with the written scope and the 365-Day Done Right Promise. If the work isn’t right, we make it right, in writing, not as a courtesy subject to manager approval.
Our crews are background-checked, uniformed, and identified by name before arrival. Tomas Reyes has led the company through 52,000+ homes served since 2013, every one documented the same way. For Redmond residents, scheduling and dispatch are coordinated from our Seattle office, with crews serving Redmond neighborhoods like Education Hill, Idylwood, and Grass Lawn every week.
Our HVAC Cleaning Services in Redmond
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and pulls heat from the air. In Redmond, coils clog with red cedar pollen, alder pollen, and Douglas fir needles that infiltrate the intake during the Eastside’s long pollen season. Debris builds on the coil surface, insulating it and forcing the blower to run longer and work harder. We clean the coil by removing the access panel, evaluating the material, then applying a coil-safe cleaner and removing the debris load. In Redmond homes from the 1988-1996 build-out, it’s common to find a coil that hasn’t been cleaned since installation and is running 12-15 degrees above design temperature.
Blower Cleaning
A dirty blower fan moves less air. That’s simple physics. Redmond’s damp air and high pollen load mean blowers here collect a paste-like film that reduces RPM and reduces airflow compensation in winter and summer. We dismount the blower wheel where access allows, clean each blade and the motor housing, and then verify amp draw and static pressure against manufacturer specs. In Overlake ranches with loose duct joints, we routinely see blower wheels weighted with damp dust and pollen that’s re-entrained into the home every time the system starts. This isn’t cosmetic. It’s a measurable airflow loss, and the fix returns the blower to rated output.
Condenser Cleaning
The condenser sits outside, usually on a pad at the side or back of the house. In Redmond’s Sammamish River valley climate, cottonwood, cedar needles, and Douglas fir debris pack the coil fins. Airflow drops, the system runs hotter, and cooling season gets shorter. We clean the condenser coil from the outside in, flush the fins, and clear the area to restore rated airflow. We also check amp draw before and after the cleaning so the customer sees the difference in electrical demand, written down, not described with adjectives.
Air Handler Cleaning
Your air handler is the cabinet that houses the blower, evaporator coil, and often a filter rack. In Redmond homes with slab foundations and uninsulated return ducts, moisture condenses inside the air handler, making it a magnet for spore and debris accumulation. We remove the access panels, inspect the interior surfaces, and clean the blower housing, coil, drain pan, and filter rack. A clean air handler matters most in aging systems where every air movement loss is compounded by degraded ductwork. In Bear Creek homes from early 1990s builds, this is the difference between a system that recovers and one that stalls under load.

BeforeAfterTrusted Brands We Service in Redmond
We work on all major makes and models found in Redmond homes: Honeywell controls, Aprilaire filtration, Abatement Technologies vacuum and HEPA equipment, and Guardsman accessories where appropriate. We don’t push a specific brand. We name the equipment we use so Redmond homeowners can verify its specifications independently before we arrive. The camera feeds from Abatement Technologies equipment, for example, deliver the before-and-after images we include in every job record. We also stock common replacement filters and basic components for these systems locally, which reduces the need for second visits.
Common HVAC Cleaning Problems We See in Redmond Homes
- Mylar liner delamination in flex duct, everywhere. The inner liner of vintage flex duct separates from its outer jacket and bunches inside the duct, creating a 30-50% airflow restriction before debris is even counted. This is the single most common finding in Education Hill and Bear Creek builds from 1988-1996. Cleaning alone doesn’t fix it. Sealing or replacing the failed section does.
- Mold in uninsulated returns under slab foundations. Sammamish valley moisture condenses inside uninsulated return ducts that run under concrete slabs. The result is a dark, damp environment where mold colonizes quickly. A standard vacuum-out can’t remediate this. The affected return sections need to be sealed or replaced, then the rest of the system cleaned under negative pressure to prevent cross-contamination.
- Pollen re-entrained by a debris-loaded blower. Redmond’s dense evergreen forest sends a lot of pollen into return air. When the blower and evaporator coil are dirty, the system loses RPM and pollen resuspends into the supply air instead of being pulled out. Homeowners notice this as a persistent film on furniture and registers, especially in Overlake ranches where supply duct joints loosen over time.
- Crushed flex runs under ranch slabs. Redmond ranch homes built before 1990 often ran flexible ducts under slab foundations with minimal support. Over decades, those runs get crushed or disconnected. A camera inspection shows the exact location and severity. In many cases, we find a full disconnect buried where the flex meets a hard pipe, meaning the system was conditioning a crawlspace or void instead of a room.
Pricing for HVAC Cleaning in Redmond, WA
A complete HVAC cleaning in Redmond, covering the evaporator coil, blower, air handler, condenser, and all accessible duct runs, runs $550 to $1,400 depending on the system size, number of zones, and what we find. Coil-only cleaning is $225 to $450. Blower cleaning alone runs $180 to $320. Condenser cleaning is $150 to $350. Air handler cleaning falls between $250 and $500. These are whole-system prices, not per-vent prices designed to inflate once the truck arrives.
Every job is quoted in writing before we start, per Haven Standard Clause 1. If we find failed flex sections or mold that requires sealing or replacement, we add a separately itemized line so the decision to repair is yours, with the photo evidence in front of you. A free second opinion on any written estimate is available. Call (806) 606-6902 for an exact written quote, not a call-back range.

FAQs - HVAC Cleaning in Redmond
Flex duct in Redmond homes built between 1985 and 1999 is now past its 25-year design life. The inner mylar liner separates from the outer jacket and bunches at fittings, blocking 30-50% of airflow before debris is even counted. You cannot clean that away. The failed section must be sealed or replaced, then the rest of the system cleaned under negative pressure. Call (806) 606-6902 and we’ll show you camera footage of your specific duct condition before recommending any work.
Living near the Sammamish River means higher ambient humidity, which penetrates uninsulated returns and slab foundations, creating the conditions for mold growth and accelerated liner delamination. Homes in the valley floor near Idylwood and the Redmond Way corridor face more condensation-related failures than hillside homes in Education Hill. Cleaning becomes urgent not because of dust, but because moisture and spores are accelerating physical degradation inside the ducts. Call (806) 606-6902 for a written assessment and price.
HEPA-filtered agitation removes what a standard truck-mounted vacuum leaves behind: the damp, adhered film of cedar pollen, alder pollen, and spore-darkened fiberglass that cements to the inner duct walls in Redmond’s humid climate. Standard negative air alone cannot break the bond. Our equipment uses mechanical agitation paired with HEPA filtration to dislodge and capture that film, not just pull loose dust. We photograph the result in every run we clean. Call (806) 606-6902 if you want to see what’s actually in your supply ducts before we clean them.
Crushed flex runs under ranch slabs in Redmond are common in pre-1990 homes. We locate the crush or disconnect with a camera inspection, mark the exact spot, and give you a written repair scope before any cleaning proceeds. In most cases, the failed section is replaced with rigid pipe or new flex and sealed correctly at the connections. The repair is itemized separately from the cleaning price. Call (806) 606-6902 to schedule a camera inspection of your duct runs.
After a standard cleaning by a company that only pulled a vacuum through the system, you may notice more humid air because the cleaning dislodged damp debris but didn’t remove it, or because a blocked drain pan was never addressed. In Redmond’s high-humidity environment, a dirty or misaligned condensate pan retains water instead of draining it. We inspect the drain pan and line as part of every air handler cleaning, and we verify condensate flow before we button the panel back on. Call (806) 606-6902 and ask for an air handler inspection with before-and-after photos, priced in writing first.
