Air Duct & Dryer Vent Cleaning questions from Clark County homeowners
A dust storm came through and there is grit on the registers. Do the ducts need cleaning?
Not after every storm. Change the filter first and wipe the registers. If grit keeps coming back after a fresh filter, the dust is already inside the trunk lines or getting in through a split joint on the return side, and that is when a cleaning and resealing pays off. The camera inspection, $79, credited toward cleaning, shows which one it is.
The AC runs all afternoon in July and never reaches the setting. Is it the ducts?
Sometimes. More often it is a coil caked with dust, or a supply run that has pulled loose and is cooling the attic instead of the room. Both show up on the photos taken during a cleaning. Coil and blower wheel cleaning is $249 to $349; reconnecting and sealing a loose run is part of the duct cleaning price.
What does duct cleaning cost in Las Vegas?
$395 to $495 for a house with one system, every supply and return run included, with split joints and dried-out tape replaced with mastic. $250 for a second system on the same day. $129 for the dryer vent, $475 to $575 with the ducts. The price comes from square footage and system count, set before the visit.
When is the best time of year to book?
Between November and March. Cooling demand at Harry Reid International is close to zero in December and January, so turning the system off for a few hours costs nothing in comfort, and the coil goes into the summer clean.
Our house in Enterprise was built in 2015. Does it need anything?
One cleaning, if it has never had one. A new system usually runs while the drywall is sanded and textured, and that dust sits in the flex and the plenums. It shows up as a white film around the registers and a dusty smell when the heat comes on the first time each winter.
What does the code say about dryer vents in Clark County?
Southern Nevada moved to the 2024 International Residential Code with regional amendments in January 2026: the City of Las Vegas on January 5, Henderson for submittals from January 2 and unincorporated Clark County on January 11. The base code caps a dryer exhaust duct at 35 feet, deducting 5 feet for every tight mitered 90-degree elbow and under 2 feet for a smooth long-radius one, and requires smooth metal duct with no screws protruding more than an eighth of an inch into the airflow, a backdraft damper at the termination, and no screen on it. A run that is too long or capped with a screen is rerouted for $150 to $400.
How often should ducts be cleaned?
The EPA says to clean when there is a reason rather than on a calendar, and in Clark County the reasons come around on a schedule: every three to five years with pets or allergies, five to seven without, once after any construction or remodel, once in a new home after the builder is done, and once after a dust storm leaves grit on the registers.
Do you clean dryer vents for apartment communities?
Yes. About three in ten of Clark County's roughly 950,000 housing units are in multifamily buildings, rising to nearly six in ten in Paradise and close to four in ten in Spring Valley, and the apartment and condo communities there commonly have long or shared dryer vent runs. An annual cleaning with photo documentation is what property managers and their insurers typically ask for. Each vent is photographed before and after, and the manager gets a dated report for the file.
What about the blower wheel and coil?
The blower compartment is vacuumed and photographed on every duct job. Pulling the blower wheel and cleaning the coil is a separate service. Nevada licenses heating and air-conditioning contractors through the State Contractors Board, and its exemption for small repair jobs does not cover work of the kind an HVAC contractor does. Duct cleaning stays inside the duct system; opening the air handler to clean the blower wheel and coil is done by or under an NSCB-licensed HVAC contractor.
Do we need the sanitizer?
Usually not. It goes on only after a cleaning and only if the camera shows growth rather than dust. It is an EPA-registered product labeled for HVAC use and costs $99 to $149.
Who does the work, and what licenses apply?
Nevada's contractor classifications do not name duct cleaning as a trade of its own. The State Contractors Board licenses heating and air-conditioning contractors, so any work past the duct system is done by or under one. The crew carries general liability insurance, works to the NADCA ACR standard, and sends before-and-after photos.
Give us the square footage, the number of systems and the year the house was built, and the price is fixed on that call.
