Why Landmark Air Duct Cleaning Service Washington Is Tigard’s Preferred HVAC Cleaning Company
Richard Anderson, our Owner and Lead Technician, has spent 11 years building Landmark into a dedicated indoor air quality specialist—not a generalist HVAC company that added duct cleaning as an afterthought. That single-trade focus shows in how we handle Tigard’s specific challenges, from collapsed flex duct in crawl spaces to the access complications of acreage properties with detached workshops.
Our 732 customers and counting have left us with a 4.9-star average rating, and that volume matters. It means we’ve seen the exact failure patterns that repeat in 1970s–1990s ranch homes from Bull Mountain to the Fanno Creek corridor. We’re not guessing when we arrive with Rotobrush and Nikro equipment sized for the job.
Owner-led on every job means Richard personally oversees your HVAC cleaning from access to completion. No rotating crews, no handoffs to technicians you’ve never met. For Tigard homeowners dealing with mold-laden duct interiors or collapsed sections, that accountability matters.
Our HVAC Cleaning Services in Tigard
Evaporator Coil Cleaning
The evaporator coil in your Tigard home’s air handler is where moisture collects and microbial growth takes hold. In our marine climate, that coil stays wet eight months of the year. We clean with professional-grade foaming agents and Rotobrush contact cleaning, then treat with a coil treatment product that inhibits regrowth. For homes near Fanno Creek where humidity runs even higher, this isn’t maintenance—it’s prevention against the coil becoming a distribution point for mold spores through your living space.
Blower Cleaning
Your blower motor and wheel move every cubic foot of conditioned air through the system. When dust and debris accumulate—accelerated in Tigard by degraded flex duct shedding fiberglass particulates—efficiency drops and motor life shortens. We remove the blower assembly, clean the wheel vanes and motor housing, and verify amp draw before reassembly. In older split-levels common in the Summerlake and Metzger neighborhoods, blower access can be tight; we come prepared for the confined spaces these homes present.
Condenser Cleaning
Outdoor condenser coils in Tigard collect cottonwood fuzz, fir needles, and the fine particulate that blows in from agricultural areas west of town. We fin-comb and chemically clean coils, check refrigerant pressures, and clear the condensate drain. For properties with workshop HVAC systems or multiple outdoor units, we schedule adequate time—no rushing through because another appointment waits across town.
Air Handler Cleaning
The air handler cabinet houses your coil, blower, and filter rack. In Tigard’s mid-generation housing stock, these units often sit in crawl spaces where ground vapor has rusted the cabinet, contaminated the interior, and degraded the filter seal. We clean and sanitize the full cabinet interior, replace deteriorated filter racks when needed, and verify that your Aprilaire or Honeywell filtration system seals properly against bypass.
Heat Exchanger Cleaning
Gas furnace heat exchangers in Tigard’s 1970s–1990s homes have decades of combustion byproduct buildup that reduces efficiency and can create dangerous CO risks. We inspect with borescope cameras, clean primary and secondary exchangers, and test for cracks or breaches. This is specialized work—Richard’s 11 years of hands-on experience means he’s seen the failure modes specific to the furnaces installed during Tigard’s suburban build-out.
Coil Treatment
After mechanical cleaning, we apply EPA-registered coil treatment products that create a residual antimicrobial barrier. In Tigard’s persistent humidity, this step separates proper HVAC cleaning from surface-level vacuuming. We use products compatible with Aprilaire and Honeywell systems, ensuring your indoor air quality equipment works as designed rather than fighting against biological regrowth.

Trusted Brands We Service in Tigard
We work with air quality systems from Honeywell, Aprilaire, Abatement Technologies, and Guardsman—brands chosen because they hold up in the Pacific Northwest’s demanding conditions. For Tigard customers, this means we stock common filters, UV lamp replacements, and media cartridges locally, so you’re not waiting on shipped parts while your system circulates dirty air. When we install an Aprilaire filtration system or Honeywell UV treatment during your HVAC cleaning, it’s sized to your home’s actual airflow, not a generic recommendation.
Common HVAC Cleaning Problems We See in Tigard Homes
- Collapsed flex duct from moisture absorption. In low-lying areas near Fanno Creek and throughout the 97223 ZIP, we regularly find flex duct sections that have absorbed ground vapor until the wire helix rusted through and the duct collapsed flat. No airflow passes. Homeowners wonder why one room never heats properly.
- Mold colonization inside duct liners. Tigard’s marine climate keeps crawl-space humidity above 70% for months. Fiberglass duct liner becomes a substrate for mold growth that standard vacuuming won’t touch. We find this disproportionately in ranch homes built 1975–1995 with original ductwork.
- Service access complications on acreage properties. Properties off SW Bany Road and similar rural roads often have detached workshops with oversized doors, locked equipment sheds, and long gravel drives that challenge standard service vehicles. We plan for this—bringing the right equipment in one trip rather than discovering access issues and rescheduling.
- Degraded filter seals and bypass contamination. In homes where crawl-space moisture has rusted air handler cabinets, the filter rack no longer seals tightly. Dirty air bypasses the filter entirely, accelerating coil fouling and blower contamination. We repair or replace these racks as part of comprehensive cleaning.

FAQs — HVAC Cleaning in Tigard
Tigard’s position in the Tualatin River Basin creates ground-level moisture that inland suburbs like Hillsboro or outer Beaverton don’t experience at the same intensity. Your crawl-space ductwork absorbs this vapor year-round, accelerating mold colonization inside duct liners and on coil surfaces. We address this with more aggressive antimicrobial treatment and more thorough drying protocols than drier markets require. Call (877) 335-1974 and we’ll assess your specific moisture load.
Yes—workshop HVAC systems often have heavier-duty components, non-standard access panels, and may be fed by extended duct runs from the main house. We bring extended-reach tools, portable power when needed, and plan for the access time that rural properties require. Our one-trip approach means we don’t discover these complications mid-job. Call (877) 335-1974 to discuss your workshop setup.
These homes were built with fiberglass-lined flex duct routed through unconditioned crawl spaces, and that liner has now had 30–50 years to degrade, shed particulates, and collapse from moisture absorption. Unlike rigid duct systems, degraded flex liner can’t be effectively cleaned—replacement becomes necessary. The sooner you inspect, the more options you have. Call (877) 335-1974 for a duct condition assessment.
We clean with Rotobrush and Nikro professional-grade systems—the same equipment used by commercial restoration contractors—and apply coil treatments and install air quality products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. For Tigard’s humidity challenges, we specify Aprilaire dehumidistat controls and Honeywell UV treatment systems that match our climate’s demands. Call (877) 335-1974 to discuss which products fit your home.
Yes—we’ve worked with heavy-duty workshop doors throughout the Fanno Creek corridor and understand the clearance and hardware requirements. We don’t force equipment through inadequate openings or prop doors in ways that strain hinges or openers. If your workshop has a separate HVAC system, we clean it with the same Rotobrush and Nikro equipment we use in main house systems, sized appropriately for smaller ductwork. Call (877) 335-1974 to schedule—mention your workshop access so we bring the right configuration.
