⚠️ FLAGGED — VERIFY BEFORE HIRING

AA Air Duct (aairduct.com)

NADCA Claim NOT Verified Verify on NADCA → Toll-Free 833 Number

⚠️ Claims "NADCA certified" but is not found in the NADCA member directory. Uses a toll-free 833 number rather than a local area code — a common spam signal. Targets Vancouver WA ZIP codes. These two signals together indicate likely credential fraud. Verify any NADCA claim directly at nadca.com/find-a-professional before hiring.

Modern Airduct Cleaning (modernairductcleaning.com)

NADCA Claim NOT Verified Verify on NADCA → Toll-Free 833 Number

⚠️ Claims "certified by NADCA and IAQA" but is not found in the NADCA member directory. Uses a toll-free 833 number. Targets Vancouver WA market. Dual false certification claims (NADCA + IAQA) with no verifiable directory listing constitutes credential fraud.

US Air Ducts / DLM Services / Family Fresh Air (Vancouver, WA)

Oregon AG Lawsuit 2019 Serial Renaming

⚠️ Oregon Attorney General filed suit in 2019 for 11M+ robocalls, 20M+ deceptive mailers, $39–$49 bait-and-switch pricing, and commission-based upselling to $1,000+. Company repeatedly renamed itself to evade complaints (US Air Ducts → DLM Services → Family Fresh Air). Washington AG filed a parallel case. If you are contacted by any Vancouver, WA-based company offering extremely low promotional pricing, verify their identity thoroughly before scheduling.

AirPath Pure (hillsboroairductcleaning.shop)

.shop Domain No Physical Address

⚠️ Uses a .shop domain — a reliable indicator of an SEO-generated lead-generation site. No physical address, no phone number, no credentials, no owner identification. Keyword-stuffed content with city names. Phone: (503) 882-9062 — verify independently that this is a local business before any engagement.

PNW Duct Cleaning (pnwductcleaning.com) — NOT PNW ProClean

White-Label Template Name Confusion Risk

⚠️ Website content references "S K COOLING INC" specializing in "air conditioner repairs for Los Angeles" — a dead giveaway of a white-label template reused across multiple markets. No phone, address, or licensing information. Name is designed to cause confusion with the legitimate PNW ProClean (pnwproclean.net). Do not confuse these two companies.

Additional Flagged Listings

Multiple Operators

⚠️ The following also triggered multiple spam signals and should be avoided: "Chimney Sweep Hillsboro" (chimneysweephillsboro.us) — explicitly a lead-gen referral network, not an actual company; "VentPure Pro" (lakeoswegoairductcleaning.shop) — .shop domain, auto-generated SEO website; "Eco Green Duct Cleaning" (ecogreenductcleaning.com) — no local phone, address, or ownership, operates across multiple cities as a national lead-gen operation; "Air Duct Cleaning Portland" (airductcleaningportland.com) — claims "#1 Best" without evidence, no business name, address, owner, or license numbers; "Best Solution Services LLC" (bestsoluti­onservices.com) — heavy Groupon presence, aggressive discounting ($55 packages, $149 unlimited vents), gmail contact, no verifiable local address; Groupon-only operators (Forest Fresh Home Solutions, Duct Guys Team, William HVAC Cleaning, Cleanland, SpotlessVents, MTcleaning, Air Wizards) offering $12–$44 deals with no independent web presence or verifiable local addresses.

Why Verification Matters for Duct Cleaning in Portland

Air duct cleaning is one of the most fraud-prone home services in the United States. The Federal Trade Commission and state consumer protection agencies regularly receive complaints about companies that advertise impossibly low prices, gain entry to a home, then pressure homeowners into paying hundreds or thousands of dollars for unnecessary additional work. Portland's market amplifies this dynamic in two specific ways: the bi-state geography creates licensing complexity that operators exploit, and the combination of wildfire smoke events and century-old housing stock creates genuine, urgent demand that bad actors target.

Oregon's 2019 Attorney General enforcement action against US Air Ducts/DLM Services/Family Fresh Air is the most documented case: over 11 million robocalls, 20 million deceptive mailers, and $39–$49 bait-and-switch offers that escalated to $1,000+ once technicians were inside homes. The company serially renamed itself to evade enforcement. Despite the AG action establishing legal precedent, our research found at least 14 suspected spam or lead-generation listings actively advertising in Portland as of March 2026 — including operators falsely claiming NADCA certification and Groupon-only companies with no verifiable local presence.

Portland's bi-state licensing landscape adds a layer of complexity that deserves clarity. Oregon requires a Construction Contractors Board (CCB) license for contracting work; Washington requires separate registration with the Department of Labor & Industries (L&I). No reciprocity exists between the states. A company claiming to serve both Portland and Vancouver, WA must hold separate licenses in each state. Only two NADCA-certified companies in this metro publish both OR and WA license numbers: Power Vac LLC (CCB #176330 / L&I #POWERVL938J6) and Better Air Northwest (CCB #195533 / L&I #BETTEAN875PG). Consumers should verify any bi-state company's credentials independently at ccb.oregon.gov and lni.wa.gov/verify.

The EPA's position remains nuanced: duct cleaning has not been conclusively shown to prevent health problems, and the agency does not recommend it unless there is visible mold, vermin infestation, or ducts are substantially clogged with debris. A reputable company will inspect your ducts first and tell you honestly whether cleaning is warranted. Every company listed below was checked against the NADCA Find a Professional directory, Oregon CCB or Washington L&I records, and at least two consumer review platforms.

How to Spot Air Duct Cleaning Scams in Portland

Our verification process flagged at least 14 suspected spam or deceptive listings in the Portland market. Here are the specific patterns we found and how to protect yourself.

What you can do: Before hiring any duct cleaning company in Portland, take five minutes to run these checks. Search the NADCA directory at nadca.com for the company name — 9 verified companies are listed for this metro. Verify their Oregon CCB at ccb.oregon.gov or Washington L&I at lni.wa.gov/verify. Confirm they have a real physical business address and a local area code. For pre-1978 homes, ask specifically about asbestos protocol before any work begins. For post-wildfire cleaning, confirm they use truck-mounted HEPA-filtered equipment and anti-microbial sanitization.

Frequently Asked Questions

Is wildfire smoke residue from the 2020 fires still in my Portland home's ductwork?

Almost certainly, if ducts were not professionally cleaned after September 2020. Portland State University research found that wildfire smoke residue containing carcinogenic PAHs (polycyclic aromatic hydrocarbons) persisted on indoor surfaces for weeks after the exposure event, even after visible smoke cleared. Smoke particles from wildfire events are extremely small — many under 2.5 microns — and penetrate HVAC systems even when windows and doors are sealed. Once trapped in ductwork, soot becomes sticky and acidic, creating breeding grounds for bacteria and mold during Portland's wet winters. Standard filter replacement is insufficient — the particles embed in duct walls, not just filters. NADCA recommends professional cleaning with HEPA-filtered truck-mounted equipment, followed by anti-microbial sanitization and potentially deodorization (thermal fogging or ozone treatment) to address embedded volatile organic compounds. Portland companies like Alameda Cleaners, Better Air Northwest, One Speed Services, and Stanley Steemer have all marketed post-wildfire cleaning packages and report sustained demand years after the 2020 events.

Should I clean or replace the original ductwork in my Portland Craftsman bungalow?

For homes with original gravity furnace ("octopus furnace") ductwork from the 1905–1935 era, replacement is generally recommended over cleaning. Gravity furnaces used oversized ducts in locations incompatible with modern forced-air systems — the old ductwork is too large, poorly positioned, and often deteriorated beyond effective cleaning. Portland's NE and SE neighborhoods, which concentrate pre-1940 Craftsman bungalows, have the highest density of this issue. Critical concern: gravity furnace ducts frequently contain asbestos insulation (white paper wrapping around pipes, white cardboard heat shields, or asbestos-containing duct cement). This material must be tested and, if positive, removed by a DEQ-certified asbestos abatement contractor before any work proceeds. Budget for furnace removal, new ductwork installation, and asbestos abatement as a combined project. Rose City Labs and Alpha Environmental both offer asbestos testing locally. Companies like AAA Heating & Cooling (in business since 1961) and Roth Home (since 1976) have the deepest experience with Portland's Craftsman-era HVAC systems.

How should my duct cleaning company handle potential asbestos in a pre-1978 Portland home?

Any reputable duct cleaning company should inspect for asbestos-containing materials (ACM) before beginning work. In Portland's pre-1978 homes — which represent nearly 45% of the entire housing stock — common ACM locations include white paper or seam tape on ducts, air-duct cement, and pipe insulation around the furnace. Oregon DEQ requires asbestos surveys before demolition or renovation of buildings constructed before 2004. If suspected material is found: do not disturb it, turn off the HVAC, close vents, and seal the area. Only a DEQ-licensed asbestos abatement contractor may remove regulated ACMs. Testing costs $50–$223 per sample — Rose City Labs offers DIY test kits at $50–$90 standard or $132 for 2–3 day rush; Alpha Environmental provides professional sampling at approximately $155 per sample. A duct cleaning company should refuse to clean ducts wrapped in suspected asbestos until lab testing confirms safety. Metro Portland disposal facilities accept up to two sealed 25-lb bags of asbestos-containing material per day at no charge.

What are the licensing differences between Portland (Oregon) and Vancouver (Washington) for duct cleaning companies?

Oregon requires a Construction Contractors Board (CCB) license with residential, commercial, or dual endorsement. This requires 16 hours of pre-license training, passing the NASCLA exam, a surety bond ($10,000–$75,000 depending on license type), general liability insurance, and a $325 biennial fee. Washington requires contractor registration through the Department of Labor & Industries (L&I), with a $15,000 surety bond (increased July 2024), minimum $200,000 liability insurance, and a $141.10 application fee. No reciprocity exists between the states — companies serving both sides of the metro must hold separate licenses in each state. Only Better Air Northwest (CCB #195533 / L&I #BETTEAN875PG) and Power Vac LLC (CCB #176330 / L&I #POWERVL938J6) publicly publish both license numbers, establishing the compliance gold standard. Consumers should verify any bi-state company's credentials independently at ccb.oregon.gov and lni.wa.gov/verify.

How much does air duct cleaning cost in Portland?

Most Portland homeowners pay $300–$800 for a complete residential duct cleaning. The budget tier ($300–$400) covers small homes under 1,500 sq ft with standard forced-air systems. Mid-range service ($400–$600) handles average homes (1,500–2,500 sq ft) thoroughly. Premium NADCA-compliant service ($600–$1,000+) includes full-system cleaning per ACR standards: all supply and return ducts, grilles, registers, air handler, blower motor, evaporator coil, video inspection before and after, and a written report. Per-vent pricing averages $21–$45 per vent (average ~$29). Oregon has no sales tax — the quoted price is the final price on the Portland side. Washington's Clark County charges approximately 7.8% sales tax, which may apply to certain service classifications. Any offer below $300 for a Portland-area home is a reliable scam indicator based on the Oregon AG's documented enforcement history.

How often should Portland homes get air ducts cleaned, given the rainy winters and wildfire seasons?

NADCA recommends every 3–5 years as a baseline, but Portland's dual-threat climate warrants more frequent attention. The combination of 155 rainy days per year with 83% average winter relative humidity creates persistent mold risk in basement and crawlspace ductwork — particularly Cladosporium, Mucor, and Alternaria species that thrive in humid HVAC systems. Homes with pets, allergy sufferers, or respiratory conditions should consider cleaning every 1–2 years. Ducts should be cleaned immediately after any significant wildfire smoke event regardless of schedule — Portland's 2020 AQI exceeded 500 for multiple consecutive days. The optimal timing is late spring (April–May) to clear winter mold accumulation before fire season, or early fall (September–October) to remove smoke and summer-season deposits before the wet season begins. Dryer vents should be cleaned every 1–2 years given Portland's climate requires heavier dryer use.

Is oil residue in my Portland home's ducts a concern after an oil-to-gas furnace conversion?

Yes, and this is a Portland-specific issue that is more prevalent here than in most U.S. cities. Many homes in NE and SE Portland neighborhoods originally used oil furnaces before converting to natural gas — a transition that accelerated from the 1960s through the 1990s. Oil combustion soot is sticky, thick, and acidic. It coats duct interiors like wet smoke damage and does not dissipate on its own. If ducts were not professionally cleaned at the time of conversion, decades-old oil residue is likely still present, continuously circulating particles when the system runs. This is a specialized cleaning scenario — standard duct cleaning equipment may not fully address heavy oil deposits. Better Air Northwest and Pearson Power Vac (Portland's primary oil furnace specialist, in business since 1997) both offer specific oil furnace duct decontamination. Oil-to-gas conversion in Portland typically costs $4,500–$7,500; professional duct cleaning should be budgeted as part of the conversion project rather than deferred.

What was the impact of the Oregon Attorney General's duct cleaning scam enforcement on the Portland market?

In 2019, the Oregon AG filed suit against US Air Ducts/DLM Services/Family Fresh Air, a Vancouver, WA-based operation that made over 11 million robocalls and sent 20 million deceptive mailers offering "$39–$49 seasonal specials." Once inside homes, commission-based salespeople upsold services to $1,000+. The company serially renamed itself — from US Air Ducts to DLM Services to Family Fresh Air — to evade consumer complaints and regulatory action. Washington's AG filed a parallel case. This enforcement action raised consumer awareness but did not eliminate the underlying pattern. Groupon and similar platforms continue to host operators offering $12–$99 "whole house" deals from entities with no verifiable local presence. The AG case established that any offer below $300 for a Portland-area home is a reliable scam indicator, consistent with documented bait-and-switch methodology.

Is air duct cleaning a scam in Portland?

Air duct cleaning itself is a legitimate service, but the Portland market has a documented fraud problem that is among the worst-documented in the Pacific Northwest. Our verification found 9 NADCA-certified companies and 20 verified non-certified companies serving the metro, alongside at least 14 suspected spam or lead-generation listings — plus at least 2 companies falsely claiming NADCA certification. The scam is not the service itself — it is the prevalence of keyword-domain operators, Groupon-only companies, and bait-and-switch pricing exploiting homeowners who cannot easily distinguish legitimate from fraudulent listings. Portland's wildfire smoke remediation demand and century-old housing stock create genuine, urgent need that bad actors target specifically. If you hire a NADCA-certified company at market-rate pricing ($300–$800), the service is legitimate and performed to an industry standard.

How do I verify a NADCA-certified duct cleaning company in Portland?

Verify four things before hiring. First, check their NADCA membership directly at nadca.com/find-a-professional — 9 companies in the Portland metro currently hold verified certification, and at least 2 other companies falsely claim it. Second, verify their Oregon CCB license at ccb.oregon.gov or Washington L&I registration at lni.wa.gov/verify — and for bi-state operators, confirm they hold separate licenses in both states. Third, confirm they have a real physical business address, a local area code (503, 971, 360, or 564), and not a toll-free number. Fourth, check at least two consumer review platforms (Google, Yelp, BBB) for consistent review histories under the same business name. For pre-1978 homes, also ask specifically about their asbestos protocol before any work begins. For post-wildfire cleaning, ask whether they use truck-mounted HEPA-filtered equipment and anti-microbial sanitization specifically — these are not universal practice.
