Frequently Asked Questions

We connect a high-powered negative air machine to your trunk line, then use compressed air tools and rotary brushes to dislodge debris from each supply and return run, drawing it out of the system entirely. In Phoenix, we typically find a mix of caliche dust, pollen, and fabric fiber that settles in low-velocity sections near the plenum. The process takes 2-4 hours for most homes. You receive before-and-after photos of every run, plus airflow readings where accessible.

Every 3-5 years for most Phoenix homes, sooner if you have pets that shed heavily, recent construction, or occupants with respiratory sensitivity. The Sonoran Desert's fine dust penetrates even well-sealed homes, and our extended AC season means systems run more months per year than in cooler climates. Homes near agricultural areas in Tolleson or El Mirage, or downwind of the Salt River bed, often accumulate faster. We can inspect and advise without charge.

It can improve airflow and reduce the load on your blower motor, but it won't fix mechanical problems. Where we see real gains in Phoenix is when supply runs are partially blocked by dust buildup, especially in homes with older flex duct in attics that reach 140°F in July. Cleaner ducts move air more efficiently; the before-and-after photos show you exactly what was restricting flow. For refrigerant or coil issues, we refer to HVAC specialists we trust.

No. The negative air machine contains debris at the collection point, and we seal registers during work. Some customers prefer to step out during the noisiest phase, but it's not required. We wear shoe covers and protect floors. If you work from home in Ahwatukee or Arcadia, we'll coordinate around your calls.

Most single-system homes take 2.5-3.5 hours from arrival to final walkthrough. Dual-system homes or those with extensive ductwork in Scottsdale or Cave Creek may run 4-5 hours. We text when the tech is en route, arrive in the window we promised, and update you if anything extends the timeline. Haven Standard Clause 2: a real window, a named tech, a text when they're on the way.

We run Nikro negative air machines and rotary brush systems, paired with Honeywell media filters for post-cleaning recommendations where appropriate. The Nikro units we deploy are built for residential and light commercial ductwork, with HEPA filtration on the exhaust so nothing recirculates into your home. For customers with Aprilaire whole-house air cleaners already installed, we coordinate cleaning to protect those components. Our tools are sized for the flex duct and rigid metal mixes common in Phoenix builds from the 1960s through today.

Yes, as a separate service with its own flat price. Dryer vent buildup is a genuine fire risk, especially in Phoenix where lint dries to near-kindling condition in summer attic heat. We use rotary tools and inspection cameras, and we document the full length of the run. If your vent terminates through the roof, we flag that access requirement upfront. Not bundled with duct cleaning, not upsold at the door.

Yes, with care. We note the location of electronic air cleaners and media cabinets, clean around them, and replace filters only if you've pre-ordered or we discuss it during the estimate. The housing itself stays in place; we clean the ductwork upstream and downstream. If your media is due for replacement, we'll show you the condition and let you decide. No "while we're in here" pressure.

Every pro working under our name is required to hold the license and insurance Arizona requires for this trade, and we verify it before they arrive at your door. Haven Standard Clause 3: verified crews, with license numbers available on request. We're also insured and bonded as a local business operating in Phoenix, Glendale, Tempe, and throughout our service area. Documentation available before booking if your property manager or HOA requires it.

It's the five-clause operating agreement every CleanRun branch works to: Clause 1, flat price in writing before work starts; Clause 2, arrive on schedule with a named tech and text notification; Clause 3, verified, licensed, insured, background-checked crews; Clause 4, evidence on every job, photos and readings; Clause 5, no surprises, no door upsell, no scope creep. We didn't invent the name to sound trustworthy; we wrote it down because specifics are what make trust possible.

Standard residential duct cleaning does not require a permit in Phoenix, Glendale, Scottsdale, or surrounding municipalities. If we discover during cleaning that your ductwork has detached or deteriorated to the point of needing repair or replacement, we'll document it, explain what we found, and advise whether that work triggers permit requirements. We don't perform structural modifications ourselves; we refer to licensed HVAC contractors we know.

We don't promise same-day service because duct cleaning is a scheduled, thorough job, not a rush repair. Our hours are Monday through Friday 7:30 AM to 8:00 PM, Saturday and Sunday 7:30 AM to 7:30 PM. We can often book within a few days, and we'll always accommodate urgent situations where a home sale inspection or health concern requires priority scheduling. Call (480) 500-6377 and we'll find the next available slot that works.

Turn off your HVAC system and call your fire department or utility emergency line first. A burning smell can indicate electrical failure, overheating motor, or debris contacting a heat exchanger, none of which duct cleaning addresses. Once the hazard is cleared, we can inspect whether accumulated debris contributed to the condition and clean accordingly. Safety first, always.

We schedule throughout our operating hours and can arrange access for customers who prefer not to be home, with your prior written authorization. In peak summer, we start early to avoid attic work during the hottest hours, which protects our crews and your equipment. If you need a specific window in Sun City West or Litchfield Park, we'll note it and do our best to accommodate.

Yes. Every job leaves a documented record: photos of every run before and after, airflow readings where accessible, and a written scope of what was done. If you believe we missed something, we return to address it. Haven Standard Clause 4 requires evidence; that same evidence protects you if results don't match what was promised. The guarantee is in writing, not implied.

Call us. We'll review the documentation with you, return if warranted, and make it right. We don't hide behind fine print. The before-and-after photos are your proof of what changed; if they don't match your experience, we want to know why. Our reputation in Phoenix, Paradise Valley, and Tempe depends on customers who can verify what they paid for.

No. Duct cleaning removes accumulated debris; it doesn't seal your home against new dust. Phoenix's climate, your filtration habits, and your home's envelope all affect how quickly particulates return. We can recommend appropriate filter upgrades, including Abatement Technologies media options for sensitive occupants, but we don't sell maintenance contracts or imply a single cleaning lasts forever. Honest scope, honest expectations.

You receive dated, labeled photos of the interior of every duct run before and after cleaning, plus a written summary of scope and any anomalies found. In 13 years, we've photographed every job this way because it's the only proof that matters. If a company won't show you the inside of your ducts, you're buying a sound, not a service. Ask to see examples before you book anywhere.
