Replace an old unit or install a new evaporative cooler sized for your home and climate.
Clean, inspect, and tune up your cooler before heat, scale, or worn parts cause a breakdown.
Replace worn or mineral-clogged pads so your cooler can move more air and cool better.
Pick the symptom closest to what you see at your Las Vegas home.
Usually dry or worn pads, or a pump that is not moving enough water.
Warm air fixesOften clogged pads, a loose belt, a slowing motor, or a damper left closed.
Not cooling fixesUsually the float valve, overflow, drain fitting, or supply line.
Find the leakCheck the pump, the float valve, and the distributor lines.
Test the pumpLas Vegas water is around 16 gpg, so white crust, clogged pads, blocked water lines, or heavy buildup in the reservoir can show up during heavy summer use.
Hard water and padsSmall part failures usually point to repair. Rust, repeat leaks, or an undersized unit point to replacement.
Repair cost guideIn Las Vegas startup follows the heat, not the frost. Light freezes are possible until about January 20, so reconnect the water after that and check pads, pump, and water flow before steady hot weather.
Summer highs near 105°F are when pads, pumps, and belts get tested. Plan a pad and water-flow check before the hottest weeks.
The median first fall freeze in Las Vegas is around December 15, with about 10 freezing nights a year. Drain the water line and pan and cover the cooler before then.
The Las Vegas water supply includes mostly Colorado River water drawn from Lake Mead, treated by Southern Nevada Water Authority facilities, and supported by local groundwater. SNWA notes that calcium and magnesium carried into Lake Mead make Las Vegas Valley water hard, so pads, pumps, floats, and distributor lines can collect mineral scale quickly.

Las Vegas has very long hot stretches, dry afternoon air, desert dust, and a short monsoon period that can briefly make evaporative cooling feel weaker. Rooftop units and older coolers often show problems first through dry pads, weak water flow, clogged distributor lines, or warm air during peak afternoon heat.
In the Las Vegas Valley, the first permit question is jurisdiction. City of Las Vegas building permits run through the city permit process, while unincorporated areas use Clark County Building and Fire Prevention. Clark County simple permits list residential mechanical permits for one appliance per permit, with separate permits needed for more than one appliance. North Las Vegas and Henderson have their own permit centers. For a new evaporative cooler, full replacement, rooftop location change, electrical work, water-line work, or duct changes, ask which permit office applies to the exact address.

Quick answers for homeowners in Las Vegas.
Hot afternoons in Las Vegas average around 105°F with about 17% humidity. Lower humidity allows more evaporation, so a cooler can work well when the pads stay wet, the pump moves enough water, and airflow remains strong.
Many common repairs fall between about $90 and $450. Access, parts, mineral scale, and urgency set the actual estimate for homes in Las Vegas.
With water around 16 gpg and about 200 cooling days a year, visually inspect the pads every 4 to 6 weeks during heavy use. Check sooner if you see dry sections, white crust, musty odor, or weaker airflow, and follow the cooler and pad manufacturer for the maintenance schedule.
At around 16 grains per gallon (gpg), Las Vegas water can leave white scale on pads, water lines, and the reservoir. Once that buildup blocks water flow, the cooler can still run but stop cooling well.
