Fast, Reliable HVAC Cleaning Across Kent
HVAC cleaning in Kent, WA typically costs between $280 and $550 for a full system service, and most Kent appointments are scheduled within 48 hours. If your vents are pushing dust, your energy bills are climbing, or your system cycles more than it should, the problem often starts where you can’t see it — inside the coils, blower, and air handler that move air through every room of your Kent home.
We’re Landmark Air Duct Cleaning Service Washington, and we’ve been driving out to Kent from Seattle for 11 years. We know the difference between a hillside home in Lea Hill and a valley-floor ranch near the SR-167 corridor — and we know those two homes often need very different approaches to the same service. Our HVAC Cleaning team brings Rotobrush and Nikro equipment directly to your door, and Richard Anderson, our owner and lead technician, personally oversees every Kent job. Call (877) 335-1974 for a free estimate.

Response time to Kent matters. We typically schedule within 48 hours and arrive with the tools and stock to complete most jobs same-day. No waiting on parts, no return trips.
Our HVAC Cleaning Services in Kent
Evaporator Coil Cleaning
The evaporator coil sits in your air handler and does the actual cooling — but in Kent’s humid valley environment, it’s also where moisture condenses and biofilm takes hold. We’ve pulled coils in 98032 homes that were coated in a gray-black slime of dust, pollen, and truck-particulate residue, reducing efficiency by 30% or more. Our process uses foaming cleaner and low-pressure rinse to restore heat transfer without damaging delicate fins. A typical evaporator coil cleaning in Kent runs $180–$320.
Blower Cleaning
Your blower motor and fan blade move every cubic foot of air your home breathes. When they’re caked with dust, the motor works harder, runs hotter, and fails sooner. In Kent’s older tract homes — especially those 1970s and 1980s builds in central Kent and East Hill-Meridian — we’ve found blowers so loaded with debris that the squirrel cage was out of balance and vibrating the ductwork. We remove, clean, and rebalance. Blower cleaning in Kent typically costs $150–$280.
Condenser Cleaning
The outdoor condenser coil faces Kent’s unique one-two punch: pollen from the Green River Valley vegetation and fine particulate from the SR-167 truck corridor. We’ve cleaned condensers near the Kent Station area where the fins were packed with a gritty black film that standard hose spray wouldn’t touch. Our process pulls the top, cleans coils from inside and out, and checks refrigerant pressure. Condenser cleaning in Kent generally runs $140–$260.
Air Handler Cleaning
The air handler is the central station — blower, coil, filter rack, and drain pan all in one cabinet. In Kent’s persistent fog and marine air, these enclosures harbor mold and mildew that spreads spores through every vent. We disassemble, clean, and treat with EPA-registered products. For homes near the valley floor in 98031 and 98032, we often recommend pairing this with duct sealing to prevent recontamination. Air handler cleaning in Kent ranges from $220–$400 depending on system size and contamination level.
Heat Exchanger Cleaning
Gas furnace heat exchangers in Kent homes collect soot and scale that can create dangerous carbon monoxide risks. We inspect with borescope cameras and clean with specialized brushes — never recommending DIY methods on this component due to the life-safety stakes. Heat exchanger cleaning in Kent runs $200–$380 and includes full combustion analysis.
Coil Treatment
After cleaning, we apply protective treatments that inhibit mold regrowth — particularly valuable in Kent’s damp climate where coils can re-contaminate within a single season. We use products compatible with Honeywell and Aprilaire air quality systems. Coil treatment in Kent adds $80–$150 to any cleaning service.

Trusted Brands We Service in Kent
We maintain and clean HVAC systems carrying Honeywell, Aprilaire, and Abatement Technologies components — brands we see regularly in Kent homes, especially in newer construction near Covington and Des Moines where builders spec’d higher-grade air quality equipment. We stock common filters, UV bulbs, and media pads so Kent customers aren’t waiting on Seattle supply houses. For sanitizing treatments, we use Guardsman-compatible products that won’t degrade manufacturer warranties.
Common HVAC Cleaning Problems We See in Kent Homes
- Valley-trapped particulate turns filters black in weeks. Kent’s position on the Green River Valley floor means diesel and industrial emissions from the SR-167 logistics corridor settle rather than dispersing. We regularly replace filters in 98032 homes that are visibly soot-dark after 30 days — a pattern our technicians don’t see in elevated Renton or Auburn neighborhoods.
- Original flex ductwork from the 1970s–1990s has deteriorated and gapped. East Kent and central Kent tract homes often have flex ducts that have sagged, torn, or separated at collars, pulling in attic insulation fibers and crawl-space debris. Cleaning helps, but we always inspect and can repair or seal as part of the service.
- Persistent fog and marine air feed mold and biofilm. Kent receives over 40 inches of annual rainfall, and the valley’s fog keeps humidity elevated even when it’s not actively raining. HVAC systems that cycle infrequently — common in spring and fall — never fully dry out, creating ideal conditions for mold growth on coils and in drain pans.
- Decades of deferred maintenance in inherited systems. Many Kent homes have had the same ductwork for 30–50 years with no professional cleaning. We serviced a 1986 tract home in the East Hill neighborhood (98042) where original uninsulated sheet-metal ducts had pulled in decades of attic insulation fibers and crawl-space debris. Using our Rotobrush system, we extracted a dense mat of fine black soot mixed with fiberglass particles that had been restricting airflow and recirculating particulates into the home.

FAQs — HVAC Cleaning in Kent
Kent sits in the Green River Valley, where geography traps diesel particulate and industrial emissions from the SR-167 logistics corridor; Auburn and Renton sit higher and receive less concentrated valley pooling. Your filters and ducts are doing their job — they’re catching what would otherwise be in your air — but they’re loading faster than systems in elevated cities. More frequent cleaning, typically every 2–3 years in Kent versus the standard 3–5 year regional recommendation, keeps airflow and efficiency intact. Call (877) 335-1974 to schedule — estimates are free.
Yes. Homes in 98031 and 98032, particularly within a mile of the SR-167 corridor, accumulate particulate at measurably higher rates than Kent’s hillside neighborhoods or nearby cities above the inversion layer. We recommend 2-year intervals for these valley-floor locations, with annual filter checks. Richard Anderson can assess your specific exposure during a free estimate visit.
They can be cleaned, but with important caveats. Flex duct from that era has often become brittle; aggressive cleaning can tear the inner liner. Our Rotobrush system is adjustable for older ductwork, and we inspect with cameras first. If we find deterioration, we’ll show you and can quote duct repair or sealing — sometimes replacing a damaged section is more cost-effective than repeated cleaning of failing material.
It does. Kent’s 40+ inches of annual rainfall and persistent valley fog create baseline humidity that keeps duct interiors damp, especially in spring and fall when HVAC systems cycle less frequently and don’t fully dry between runs. Mold and biofilm grow on coils and in drain pans first, then spread. Our cleaning includes treatment, and we can recommend humidity control strategies specific to your home’s location and construction.
We use a two-stage approach: our Nikro HEPA vacuum creates negative pressure at the register while the Rotobrush agitation system loosens embedded fibers from duct walls. Fiberglass and cellulose insulation particles respond differently — we adjust brush stiffness and vacuum flow accordingly. For homes with significant attic leakage, we also inspect and can seal duct collars to prevent re-infiltration. Call (877) 335-1974 and we’ll show you exactly what we’re extracting.
