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 Maple Valley’s Preferred HVAC Cleaning Company
Maple Valley homeowners keep our schedule full because we run a different kind of operation. Every technician who arrives at your door is background-checked, uniformed, and holding professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. You will know their name before they ring the bell, and you will have a written price in hand before a single panel comes off your air handler.
We are part of the Relay Home Co. family, founded 2005, and every location is independently owned but held to The Relay Visibility Guarantee. That means you get a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. No vague four-hour windows. No surprise line items. Omar Haddad leads our team, and he built the standard around one idea: you should see exactly what you paid for.
Dispatch and scheduling for Maple Valley are coordinated from the brand’s Seattle office, but the crews working in your home are local to this area and know the housing stock. We answer the phone with a live person around the clock, so when you call with a question about your return ducts or a filter fit, you are talking to a human, not a voicemail loop.
Furnace Duct Cleaning in Maple Valley
Furnace duct cleaning in Maple Valley means removing the accumulated dust, pet hair, construction debris, and sometimes dryer lint that builds up inside your supply and return ductwork. The job involves connecting a negative-pressure vacuum system to your duct network, then running agitation tools through each run to loosen debris so it gets pulled into the HEPA-filtered exhaust instead of back into your living room. Most Maple Valley homes with a single furnace run $425 – $675 for a complete cleaning.
Supply and Return Runs
We clean both sides of the system, not just the returns you can see. On older Four Corners homes, return ducts often run through finished basements and tight joist cavities, which takes longer and matters for pricing honesty. We quote per system, not per vent, so a 14-run home and an 18-run home with the same trunk layout cost the same.
Filter Housing and Trunk Lines
The trunk lines carry the bulk of what your furnace pushes through the house, and they are where we usually find the heaviest buildup. We also check the filter housing and replace the filter if needed. If you have an Aprilaire media cabinet, we can supply the correct replacement on the spot.
AC Coil Cleaning in Maple Valley
AC coil cleaning in Maple Valley is a separate job from duct cleaning, and it addresses the evaporator coil inside your air handler and the condenser coil on the outdoor unit. When coils are caked with dust, pollen, and the fine particulate that drifts across the Cedar River watershed, your system works harder and cools less. Coil cleaning for a standard Maple Valley home runs $185 – $320 depending on access and coil condition.
Evaporator Coil Service
The evaporator coil sits in the air handler, and in Maple Valley’s split housing stock, access varies from wide-open utility closets in newer plateau builds to cramped crawlspace air handlers in 1980s Four Corners homes. We remove the panel, inspect the coil, clean it with the appropriate coil cleaner, and treat it to resist future buildup.
Condenser Coil Service
The outdoor condenser coil gets hit by cottonwood, grass clippings, and the damp air that settles in the valley. We rinse and clean it carefully, straighten bent fins where possible, and verify the system is moving air properly before we leave. Clean coils on both ends means lower energy use through Maple Valley’s warm summer months.
Trusted Brands We Service in Maple Valley
We work on systems from every major manufacturer, and we stock common filters and parts for Maple Valley customers so you are not waiting on a shipped component. That includes Honeywell and Aprilaire filtration products, plus Guardsman filters. Our cleaning equipment is professional-grade: Rotobrush rotary brush systems for agitation, Nikro HEPA-rated negative air machines for extraction, and Abatement Technologies containment units when a job calls for it. If your system takes a specific filter size or coil cleaner, we bring it on the first visit.
Common HVAC Cleaning Problems We See in Maple Valley Homes
- Drywall dust from remodels. On a 1990s two-story off SE 248th in the Lake Wilderness area, our tech pulled the air handler panel and found the blower motor caked in drywall dust from a remodel two owners back. That dust had been circulating through the supply and return ducts for years, and it took full agitation under negative pressure with HEPA filtration to clear it.
- Bypassed or undersized filters. Many Maple Valley homes run a 1-inch fiberglass filter that does almost nothing for fine particulate. We often recommend a proper MERV-rated filter or an Aprilaire media cabinet, especially in homes near wooded lots off Witte Road or along the Cedar River corridor.
- Pet hair and dander in returns. Homes in Lake Wilderness and the newer plateau subdivisions with multiple pets accumulate fur quickly. That material packs into return boots and reduces airflow, which forces the blower to work harder and can shorten its life.
- Second-floor temperature imbalance. In older Four Corners builds, trunk runs to upstairs bedrooms often have poor damper placement, and dust accumulation makes it worse. After cleaning, airflow improves measurably, but we will also tell you honestly if a balancing damper adjustment is the real fix.
Pricing for HVAC Cleaning in Maple Valley, WA
Here is the honest math for Maple Valley. Furnace duct cleaning runs $425 – $675 for a standard single-system home, one flat price per system agreed before work starts. AC coil cleaning runs $185 – $320, and if you combine duct and coil cleaning on the same visit, the total lands between $550 and $850 depending on system count and access. We never charge per vent. We never quote low over the phone and negotiate upward at the door. The price Omar Haddad’s team hands you in writing is the price you pay, no exceptions.
What moves the number within those ranges? Finished basements that block trunk access in older Four Corners homes. Extremely long runs to a second floor on the plateau. A system that has gone a decade without cleaning. That is why we offer a free on-site estimate, not a phone guess. Call (737) 727-2314 and we will come look at your actual system before quoting.

FAQs About HVAC Cleaning in Maple Valley
Every 3 to 5 years for most Maple Valley homes, and closer to 3 if you have pets, recent remodeling, or a home near unpaved roads or heavy tree cover. The honest answer is that some homes do not need it as often as they are told. A newer plateau build with a clean air handler and well-sealed ducts may only need a camera inspection and a filter correction, not a full source removal. We will tell you which one you need, even if it means a smaller job for us. Call (737) 727-2314 and we will inspect before recommending anything.
One flat price per system, always. We never charge per vent, never quote a low teaser number over the phone, and never negotiate upward once we see your second-floor trunk runs or finished basement. The written price Omar Haddad’s team gives you before work starts is the exact price on your invoice. If you want an exact quote for your Maple Valley home, call (737) 727-2314 for a free estimate.
Duct cleaning removes accumulated dust, pet dander, and debris from the duct network, which can reduce what recirculates through your home, but it is not an allergy cure. You also need good filtration, regular filter changes, and sealed ducts for the full benefit. We will check all of those while we are in your Maple Valley home and recommend the right MERV rating for your system. Honest answers come with every job.
Furnace duct cleaning clears debris from the supply and return ductwork that moves air through your home. AC coil cleaning addresses the evaporator coil inside the air handler and the condenser coil outside, where dust and debris reduce heat transfer and drive up energy use. They are separate jobs with separate pricing. In Maple Valley, furnace duct cleaning runs $425 – $675, and AC coil cleaning runs $185 – $320. Both are often scheduled together for efficiency. Call (737) 727-2314 for a combined quote.
We use professional-grade portable equipment from Nikro, Rotobrush, and Abatement Technologies. That includes HEPA-filtered negative air machines that pull loosened debris straight into a sealed vacuum path, not a shop-vac that blows dust back into your home. Portables also mean we can work in Maple Valley homes with tight driveways, steep lots on the plateau, or HOA restrictions where a truck-mounted unit would be impractical. The result is the same or better, and you get before-and-after photos proving it.
