Liberty Duct
FAQ

NADCA recommends every 3–5 years for typical homes. In Salt Lake City and the Wasatch Front we recommend the 3-year end of that range because of winter inversion particulate plus summer wildfire smoke that gets sequestered in duct walls and recirculates as soon as the system runs.

A typical SLC single-family home with one HVAC system takes 2–4 hours. Two-system, two-furnace, or larger 4,000+ sq ft homes take 4–6 hours. We never rush — quality of cleaning is directly tied to time spent agitating each branch run.

Source-removal cleaning of the full HVAC system: every supply register, every return register, the trunk lines, the plenum, the blower wheel, and the evaporator coil. If your provider is not opening the air handler and brushing out the blower, you are getting a register-vacuum, not a duct cleaning.

Yes — every accessible supply and return register is removed, vacuumed, washed if grease or kitchen residue is present, and reinstalled. We replace any rusted or warped grilles on request.

Truck-mounted HEPA-filtered negative-pressure vacuum (5,000+ CFM) plus rotary brush systems and high-pressure air whip for agitation. We measure static pressure with a manometer before and after the job to prove the result.

Yes — but only if the cleaning is real. Surface "register sweeps" do nothing for dust because the source (deposits inside trunk lines and the blower wheel) keeps re-supplying. Source removal addresses the cause.

Removing accumulated pollen, dander, dust mite waste, and pet hair from the duct system reduces what cycles through the air every time the HVAC turns on. Combine with a UV-C lamp + MERV-11 or higher filtration for measurable allergy improvement.

No. We seal off all register openings except the one being agitated, run negative pressure through the truck-mount, and lay protective floor coverings. Most customers stay home during the work.

Yes. We open access panels in plenum sections behind drywall only with prior written consent, and we patch them when finished. In most homes the ducts are accessible from inside the air handler closet.

Yes — 100% satisfaction. If you find a missed register, an obvious leak we did not address, or a debris path we left behind, we return at no charge.

Once a year minimum. Households with pets, large families running 5+ loads/week, or vent runs longer than 15 ft should clean every 6 months.

The U.S. Fire Administration links clogged dryer vents to roughly 2,900 home fires per year, mostly from lint accumulating on the heating element. It is one of the highest-impact, lowest-cost preventive services we offer.

Five common signs: clothes take more than one cycle to dry, the dryer feels hot to the touch, you smell a burning lint odor, lint is visible at the exterior cap, or the laundry room is humid during cycles.

Yes — fresh installs and reroutes. We use rigid 4" galvanized duct, never flex hose inside walls. Code-compliant slope, exterior cap with backdraft damper, and proper securing at every joint.

IRC code limits dryer vent runs to 35 ft, minus 5 ft per 90° elbow. Many existing runs exceed effective limits because of bends. We measure and reroute on the shortest practical path.

Yes — we handle apartment complexes, townhouses, and shared dryer-vent risers. Coordination with HOAs and exterior penetrations on stucco, siding, and brick is routine for us.

Same vent rules apply, but gas dryers also need adequate combustion air. We verify gas dryer venting is rated for the appliance and confirm combustion air supply during install.

In long runs that cannot be physically shortened, we install in-line dryer booster fans with lint-resistant blades to maintain code-compliant airflow.

A UV-C germicidal lamp mounted near the evaporator coil exposes air and the coil surface to 254 nm ultraviolet radiation. UV-C breaks down DNA in mold spores, bacteria, and most viruses, neutralizing them on contact.

Yes — the lamp is sealed inside the HVAC system. UV-C never escapes into living spaces. Technicians wear UV-rated eye protection during installation.

Quality UV-C bulbs maintain peak germicidal output for 9–14 months. We service annually and replace as needed — a depleted bulb still glows blue but has lost its kill rate.

Possibly. Clean evaporator coils transfer heat better, so the AC achieves target temperature faster. Most owners report a 5–15% efficiency improvement after coil-mount UV plus coil cleaning.

Different jobs. UV-C kills what passes the lamp and what grows on the coil. Bipolar ionization (iWave, REME) works throughout the home and addresses VOCs. Best results combine both.

AC in spring (April–May), furnace in fall (September–October). Tuning before peak demand catches small problems before they become emergency callouts at the worst time.

Static pressure measurement, refrigerant charge check, temperature differential, thermostat calibration, electrical connection torque, capacitor test, contactor inspection, condensate drain flush, blower amp draw, filter inspection, evaporator coil visual, ignition cycle test, safety control verification, and more.

Yes — most manufacturer warranties require annual professional service. A skipped tune-up year can void coverage on a $5,000+ furnace.

60–90 minutes for a single-system home. Multi-system homes 2 hours.

Two main paths: condensation on cold AC components during summer (the evaporator coil is the prime spot), and humid air entering crawlspace ductwork. Once spores establish, the HVAC distributes them throughout the home.

Visible mold near supply registers, persistent musty smell when the HVAC runs, allergy or asthma flare-ups when the system is on, or dark spotting on the air handler interior.

Cleaning removes dust and debris physically. Sanitizing applies an EPA-registered antimicrobial fog to neutralize residual bacteria. Remediation is the structured response when active mold growth is confirmed — containment, HEPA vacuum, antimicrobial treatment, and source elimination (UV-C, humidity control).

Yes — products we use are EPA-registered for residential HVAC. Surfaces are safe for pets and children once dry, typically within 2 hours.

Most single-family SLC homes price between $300 and $650, depending on number of supply vents, returns, and furnaces. Multi-system or larger homes run $700–$1,200. Every quote is written and flat-rate before work begins.

They are not. The $59 ad gets the truck in the driveway; the actual invoice for a real cleaning lands at $400+ after upsells. Our flat $300+ price is for a complete service the first time, with no upsells.

No — quotes are free, written, and locked. We do not charge dispatch or estimate fees.

Card (Visa, MC, Amex, Discover), check, cash, and ACH for commercial accounts.

For projects over $1,500 we can offer 0% APR financing through GoodLeap or Synchrony, subject to credit approval.

100% satisfaction. If you can identify any portion of the scope that was not completed, we return at no charge until you are satisfied.

If you are within 60 miles of Salt Lake City 84103, yes. That includes Salt Lake County, most of Davis, Weber (Ogden, Roy), Tooele, Wasatch (Heber), Summit (Park City), and Utah County up to Provo.

Same-day service is available in 80%+ of our ZIPs. Calls placed before noon usually get same-day arrival; otherwise next business day in 95%+ of cases.

After-hours messages are reviewed by 7 a.m. For true emergencies (active fire, water damage), call 911 first.

We give 1-hour windows, not 4-hour all-day windows. Most homeowners call those out as the single biggest difference vs other companies.

Yes — many customers leave a key with us or use a smart lock. We bill on completion, send the written report by email, and follow up with a satisfaction call.

Yes — we coordinate building-wide air duct, dryer vent, and laundry-room riser cleanings for HOAs, property managers, and apartment owners. Master service agreements available.

We handle kitchen-side dryer vents and HVAC duct components. For full Type-1 grease hood + exhaust cleaning, we coordinate with a partner specializing in NFPA 96 compliance.

Yes — we issue COIs naming the property as an additional insured before the first job. Standard turnaround 1 business day.

Yes — annual or quarterly schedules with discounted rates and priority scheduling for commercial accounts.

Yes — Liberty Duct and Vent, LLC is fully licensed and insured in the state of Utah. Certificates of insurance are available before any job.

NADCA membership and ASCS technician certification are in process. Our cleaning process already follows the NADCA ACR (Assessment, Cleaning, Restoration) standard — source removal, source containment, full-system access.

BBB accreditation is in process. We can be searched by name on the BBB Utah profile today; the accredited badge will follow standard review.

Liberty Duct and Vent, LLC is owned and operated by Raz Hadary, headquartered at 255 N 400 W, Salt Lake City, UT 84103. Raz is on most jobs personally — this is not a franchise or call-center operation.

Three things: (1) we clean the entire HVAC system, not just registers; (2) every quote is written, flat, and locked before work; (3) the owner is on most jobs. The combination is rare in the SLC market.
