Blower, Coil and Plenum Cleaning in Las Vegas

Cleaning the ducts without cleaning the air handler leaves the dirtiest part of the system untouched. The blower wheel collects a dense layer of dust that cuts airflow, the evaporator coil clogs with the same dust mixed with condensation and grows biological growth, and the drain pan under it turns into a sludge tray. Clark County systems run hard from May through September, with July highs averaging 104 degrees and about 78 days a year at 100 or above, and a coil coated in dust is the most common reason a system cools poorly, ices up or runs all afternoon without reaching the thermostat setting.

What HVAC system cleaning includes

• Blower wheel and housing: removed or cleaned in place depending on the unit, every blade degreased and the housing vacuumed.
• Evaporator coil: cleaned with a coil-safe foaming cleaner and rinsed, fins straightened where bent.
• Drain pan and condensate line: pan cleaned, line flushed and treated so it stops backing up.
• Supply and return plenums: cleaned and sealed where joints are leaking.
• Filter rack checked for gaps that let air bypass the filter.

When you need it

• Airflow is weak at the registers even after a new filter.
• A musty smell when the system first turns on.
• The system freezes up or the drain line backs up repeatedly.
• The coil has never been cleaned and the system is more than five years old.
• Duct cleaning camera shows the blower compartment caked.

Licensing

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. We tell you when a problem is a repair rather than a cleaning and do not sell you one disguised as the other.

Pricing

Blower and coil cleaning in Las Vegas runs $249 to $349 per system, less when done with a whole-house duct cleaning. A coil fouled badly enough to need pulling gets a new number after the crew has looked at it.

Weak airflow after a fresh filter, or a musty smell at startup, points at the air handler. Call (725) 361-2868 and we will put a camera in the blower compartment in Las Vegas and across Clark County.
