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 Maltby
HVAC cleaning in Maltby typically costs between $450 and $850 for a full system and is usually completed in a single 3 to 6 hour visit. Most homes along Highway 522 and the surrounding rural roads need the evaporator coil, blower, and full duct runs cleaned to address dust, pet hair, and the fine sediment that accumulates fast out here. We know Maltby’s housing mix well: older homes off Paradise Lake Road, newer construction near the Snohomish County line, and everything in between. Call Cardinal Air Duct Cleaning at (737) 727-2314 for a written price before any work starts.
Why Cardinal Air Duct Cleaning Is Maltby’s Preferred HVAC Cleaning Company
Our HVAC Cleaning team works throughout Maltby on a regular basis, so we understand what these systems actually look like. Homes here vary more than almost anywhere else in the region. A 1960s rambler south of CR-9 has a completely different duct setup than a 2015 build off 180th Street SE. That matters when you’re quoting a job, and it matters when you’re doing one. Our crews arrive with the right equipment for the actual house, not a generic checklist.
Every job is performed by background-checked, uniformed technicians who run Rotobrush agitation systems paired with Nikro HEPA vacuums. We also carry Abatement Technologies containment units when a job calls for it, which happens more often in Maltby than in denser areas. Older ducts, rodent activity, heavy dust from gravel driveways and unpaved roads all contribute to that. We price the job honestly up front, and the price does not move once we’re on site.
AC Vent Cleaning in Maltby
AC vent cleaning in Maltby usually runs $300 to $500 as part of a broader system cleaning, depending on the number of returns and whether the air handler needs opening. In many Maltby homes, vents and registers pull in dust from nearby unpaved roads, pet dander, and pollen from the surrounding tree cover. That buildup settles into the register boots and starts recirculating every time the AC kicks on.
Register and Boot Decontamination
We remove each register, clean the visible boot with a HEPA vacuum, and then work the flex or rigid duct behind it. In older Maltby homes, we often find the boot itself is the dirtiest component because it’s the first thing incoming air touches. Cleaning it properly takes more than a quick wipe.
Source Removal, Not Just Air Blowing
Our approach uses negative-pressure extraction, which means the loosened debris goes straight into the Nikro HEPA vacuum rather than back into your living room. That distinction matters a lot in tight, well-sealed newer Maltby construction where any stirred-up dust hangs around for days.
Furnace Duct Cleaning in Maltby
Furnace duct cleaning in Maltby typically runs $450 to $700 for a complete supply and return run, including the main trunk. Homes that run heat heavily from October through April here see significant accumulation of fine particulate, especially if anyone in the home has allergies or pets. For properties on gravel drives or unpaved access roads, that figure trends higher because more sediment gets tracked in and pulled through the returns.
Supply and Return Ductwork
We clean both sides of the system. The supplies push heated or cooled air into rooms, and the returns pull room air back to the furnace. If you only clean the supplies, you leave half the system dirty. In Maltby’s older homes, returns are often undersized and pull hard, which means they collect more debris faster than a modern system would.
Main Trunk and Branch Lines
The main trunk is the large duct running off the furnace or air handler. In a 1970s split-level off Paradise Lake Road, we recently cleaned a supply and return system where the homeowner noticed musty odors and visible dust at the registers. Using a Rotobrush agitation tool and HEPA filtration, we pulled out a substantial amount of rodent nesting material and drywall dust from the main trunk, then showed before-and-after photos of the ducts on our tablet. The homeowner added furnace duct cleaning while we were there, and the musty smell was gone by the time we packed up.
Trusted Brands We Service in Maltby
Cardinal Air Duct Cleaning services all major HVAC brands found in Maltby homes, including Carrier, Trane, Lennox, Goodman, Rheem, and Bryant. We also work on Mitsubishi and Daikin mini-split systems that are common in newer construction and converted garages. Because our techs carry a range of coil cleaners, treatment products, and access fittings on the truck, most parts and supplies are on hand without waiting on a parts run. For Maltby residents, that means less down time and one fewer trip across town.
Common HVAC Cleaning Problems We See in Maltby Homes
- Rodent and pest debris in duct runs. Maltby’s heavily treed lots and proximity to wooded areas mean mice, rats, and squirrels find their way into ductwork more often than homeowners expect. We regularly remove nesting material from trunk lines and branch ducts during routine cleanings.
- Construction dust from remodels and additions. Many Maltby homes have been expanded or renovated over the years. Drywall dust and sawdust make their way into the return air stream and coat the coil and blower wheel. That reduces efficiency and pushes dust back into rooms.
- Clogged evaporator coils from infrequent filter changes. With the amount of pollen and outdoor particulate in this area, a neglected filter loads the coil quickly. Once the coil is coated, the system has to work harder to cool, which raises energy bills and shortens equipment life.
- Dirty blower wheels causing airflow problems. A blower wheel caked with dust and pet hair moves far less air than a clean one. In Maltby’s older forced-air systems, that lower airflow makes the furnace run longer and the AC struggle during the summer months.
Pricing for HVAC Cleaning in Maltby, WA
A standard HVAC cleaning in Maltby runs between $450 and $850 depending on the size of the home, the number of system components, and how long it has been since the last cleaning. A compact single-story rancher will land near the low end, while a larger two-story or a home with multiple returns and a heat pump central system comes in higher. Furnace duct cleaning alone typically runs $450 to $700. AC vent cleaning as an add-on during a full system job runs $300 to $500.

FAQs About HVAC Cleaning in Maltby
Most Maltby homes benefit from a full duct cleaning every 3 to 5 years, though homes with pets, smokers, recent renovations, or gravel driveways may need it more often. The systems that need it most are the ones that have never been cleaned. Call (737) 727-2314 and ask us about your specific home’s age and setup.
We quote one flat price per system, agreed in writing before we start. No per-vent pricing, no surprise add-ons for the air handler or blower motor once we’re on site. The number you sign off on is the number you pay.
We start with a camera inspection of the trunk and branch lines, then set up negative pressure using a Nikro HEPA vacuum at the air handler. Rotobrush agitation tools loosen debris from the duct walls while the vacuum captures it at the source. After the ductwork is clean, we address the coil, blower, and air handler if you’ve opted for full HVAC cleaning. We finish with before-and-after photos of the inside of your ducts.
Yes. In a standard Maltby home that runs a forced-air furnace and central AC, the same ductwork serves both functions, so one cleaning covers both the heating and cooling sides. If you have a separate mini-split system or a secondary air handler, we can address that in the same visit for an additional flat charge agreed up front.
We do not promise same-day service. A proper NADCA-standard cleaning on Maltby’s older, sometimes oddly routed duct systems takes time to set up and do correctly. Rushing the job means incomplete source removal and debris left behind. When you book, you get a live arrival window you can track, so you know exactly when we’ll be there. Call (737) 727-2314 to schedule a time that works for you.
