HVAC Mold Cleaning in Henderson, NV
The air handler sits on a platform in the garage, or on a catwalk in the attic, and every time it kicks on in July there is a wet, sour smell in the hallway for the first minute. The platform under it has a water stain and the drywall beside it is speckled. This site connects you by phone with an independent local provider who does HVAC mold cleaning in Henderson and across Clark County.
Inside the cabinet on a 110-degree afternoon
The crew opens the cabinet. Inside are the coil, which is wet all summer, the drain pan under it, the insulation lining the cabinet, and the condensate line that carries the water outside or into a drain. In Henderson the line clogs with dust and algae in the hottest weeks, the pan overflows onto the platform, and the cabinet sits in water while the blower runs eighteen hours a day.
Next come the ducts. In an attic that hits 140 degrees, a duct that leaks cold air sweats on the outside and drips onto the insulation below. A flashlight and a camera at each register tell them whether the growth lives on the cabinet, the coil, or inside the flex duct.
Find the condensate line and set the fan to auto
Do not spray a cleaner into the return grille or the cabinet, and leave the store-bought foggers on the shelf; either one sends chemicals through the ducts to every room in the house. Set the thermostat fan to auto so the blower runs only while cooling.
Go outside and find the condensate drain, a small PVC pipe near the outdoor unit or through the garage wall. If nothing drips from it on a hot afternoon while the system is running, the line is clogged. Look at the platform for standing water or a rusted pan. Note the age of the system from the sticker inside the cabinet door.
Metal is cleaned, duct liner and wet insulation leave
The metal parts stay. The crew cleans the coil where it sits, flushes or swaps the pan, and blows out the condensate line, and most add a float switch so the next clog shuts the unit down instead of flooding the platform. The cabinet is HEPA vacuumed and wiped.
The porous parts do not come clean. Fiberglass duct board, the cabinet's old liner insulation, flex duct with growth inside, and the attic insulation under a sweating run are pulled and replaced. Drywall beside a garage platform that stood wet is a separate job; see mold removal. Growth on the sheathing above a sweating duct is attic mold remediation. A musty smell that stays after the cabinet is clean is mold odor removal.
Attic air handlers, swamp coolers, and which permit applies
Henderson homes from the 1990s on mostly put the air handler in the attic or the garage, with flex duct in an attic that runs far hotter than the air outside. The system runs from May into October, and the condensate it makes in that stretch is the most water many of these houses ever see. Older houses near the Water Street District and in Black Mountain often still have a rooftop evaporative cooler as well; its pad water and its float valve leak into the same duct chase the air handler uses.
Cleaning a coil and clearing a drain is air-conditioning work. Removing growth-affected drywall and insulation is remediation, which Nevada does not license separately; the provider represents its own training, and the rebuild is contractor work under the Nevada State Contractors Board. Replacing a system or rerouting a drain line needs a mechanical permit through the City of Henderson or Clark County. Nevada policies often treat condensation damage as maintenance rather than a covered loss.
Calling about the smell when the air handler starts
Have the address, how old the system is, and whether the air handler is in the garage or the attic. Say whether the smell is only at startup or all day, whether the drain has ever backed up, and whether there is a swamp cooler on the roof. Call (702) 602-8512.
