Frequently Asked Questions

We connect a powerful HEPA-filtered vacuum to your main trunk line, then use compressed air whips and brushes to dislodge debris from every branch and register. The process takes 2–4 hours for most Austin homes, with zero mess — we seal off rooms and protect floors. In Bee Cave and Lakeway homes with crawl space ductwork, we also inspect for moisture intrusion that causes mold. You'll see real-time camera footage of the buildup we're removing, and we do a final airflow test to confirm results.

Most residential jobs in Austin take 2–4 hours from arrival to cleanup. Larger homes in Shady Hollow or Buda with 4+ zones may need 5–6 hours. We don't rush — thorough cleaning means accessing every vent, not just the easy ones. Same-day service is available if you call before noon. We'll give you a precise time estimate when you book at (833) 315-4216.

Every 3–5 years for most Austin homes, though allergy sufferers and pet owners often benefit from every 2–3 years. Austin's cedar fever season, construction dust from booming Kyle and Manor development, and our clay-heavy soil that tracks indoors all accelerate buildup. If you've renovated, had water damage, or notice dust returning within days of cleaning, it's time. We send reminder texts based on your home's specific conditions.

Yes — our equipment runs outside or in your garage, and we seal active work areas to contain any loosened dust. Most customers in Jollyville and Anderson Mill work from home without disruption. If you have severe allergies or respiratory conditions, stepping out for the first hour may be more comfortable. We use HEPA containment, so nothing circulates back into your living space.

Clean ducts typically improve HVAC efficiency 10–25%, which in Austin's brutal summer heat can mean $30–$80 monthly savings. Restricted airflow forces your system to run longer — we regularly find 30–50% airflow improvement after cleaning in Pflugerville and Wells Branch homes. The real test: your system's static pressure reading, which we measure before and after. Lower pressure means your blower motor works less hard.

We use truck-mounted vacuum systems from Abatement Technologies paired with pneumatic whip systems and HEPA-filtered portable units for tight-access jobs. For homes in Lakeway and Bee Cave with delicate flex duct, we switch to softer-bristle rotary brushes to prevent damage. Our technicians also carry Aprilaire media filters and Honeywell UV air purifiers for customers wanting upgraded filtration. Everything's commercial-grade — not the shop-vac setups some budget operators use.

Yes — we install Honeywell UV treatment systems and Aprilaire whole-home air purifiers that integrate directly into your existing ductwork. UV lights run $400–$800 installed and neutralize mold, bacteria, and viruses circulating through your system. In Austin's humid months, we see significant mold reduction in homes near the Colorado River and Shady Hollow's low-lying areas. We'll assess your duct layout and recommend placement for maximum exposure time.

We recommend MERV 11–13 pleated filters for most Austin homes — high enough to catch pollen and fine dust without straining your blower motor. In new construction areas like Buda and Kyle where drywall dust lingers, MERV 13 helps. We stock Aprilaire media filters that last 6–12 months versus monthly changes. Skip the cheap fiberglass ones — they barely stop visible dust and let everything recoat your freshly cleaned ducts.

Yes — Nova Air Duct Cleaning Service Austin is fully licensed by the Texas Department of Licensing and Regulation, carries general liability insurance, and maintains workers' compensation coverage. Douglas Ross has held our state license since 2016, and we carry $1 million in liability protection. In Texas, anyone can claim to clean ducts; proper licensing means we've passed background checks and meet continuing education requirements. We'll provide proof of insurance on request before any work begins.

No permit is required for standard residential air duct cleaning in Austin, though duct modification or replacement may trigger permitting through the City of Austin Development Services Department. If we're cutting into walls, altering trunk lines, or working in historic districts like parts of Hyde Park, we'll handle any required permits. For straightforward cleaning in Kyle, Pflugerville, or Manor, we arrive and work same-day without bureaucratic delay.

Ask for their TDLR license number and verify it at texas.gov — then confirm active insurance certificates directly with their carrier, not just a photocopy. Check how long they've operated locally; we've been at the same Austin number since 2016 with 1,255 verified reviews. Be wary of out-of-town crews who appear after storms or advertise "$79 whole house" specials — they're often unlicensed and use bait-and-switch tactics we've seen hurt homeowners in Jollyville and Hornsby Bend.

Yes — we offer same-day emergency service across Austin, Shady Hollow, Buda, and Bee Cave when you call before 2 PM. True emergencies include visible mold blowing from vents, sewage backup contamination, or post-fire smoke damage where every hour worsens the situation. Our emergency rate applies, but we'll be there. For standard cleanings, we typically book within 48–72 hours. Call (833) 315-4216 now if you're dealing with contamination — we'll prioritize your health and safety.

Water damage with active mold growth, rodent or insect infestation in ducts, and post-fire smoke contamination all require immediate professional response. Austin's humidity after spring storms creates mold within 24–48 hours in damp ductwork — we've rescued homes in Wells Branch and Lakeway after HVAC condensate line failures. If you smell mustiness, see debris blowing from vents, or your family experiences sudden respiratory symptoms, treat it as urgent. Don't run your HVAC until we've assessed it.

We answer live during business hours and return after-hours messages within 30 minutes. For emergency calls in Austin, Kyle, or Manor, our technician is typically en route within 1–2 hours. Scheduled appointments arrive in a 2-hour window — not the "sometime between 8 and 5" other trades offer. Douglas Ross personally monitors our dispatch board to ensure no one waits unnecessarily when air quality is at stake.

Yes — we guarantee visible debris removal and measurable airflow improvement, documented with before-and-after photos and pressure readings. If you're not satisfied, we'll return within 30 days to re-clean at no charge. Our 8+ years in Austin and 4.9-star average across 1,255 reviews reflect how seriously we take this. We don't consider a job done until you see and feel the difference in your home's air.

Honeywell UV systems carry a 5-year manufacturer's warranty on the ballast and 1 year on bulbs; Aprilaire purifiers include a 5-year warranty on the unit itself. We add our own 1-year installation warranty covering labor and any fitment issues. In Austin's hard water areas like Anderson Mill and Jollyville, we check UV sleeve scaling annually — included if you're on our maintenance plan. Replacement bulbs run $45–$75 and typically last 9,000–12,000 hours.

We investigate the source — often it's a failing filter, duct leaks pulling attic dust, or construction nearby in booming areas like Buda or Manor. Our guarantee includes a 30-day follow-up inspection if you're seeing rapid reaccumulation. We've found disconnected return ducts in Lakeway attics and missing filter racks in Pflugerville new builds that made previous "cleanings" pointless. We fix the root cause, not just the symptom.
