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 Denver 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 pumpDenver water is around 5 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 guideThe median last spring freeze in Denver is around May 5. Turn the water back on and start the cooler after that, once warm days are steady.
Summer highs near 90°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 Denver is around October 9, with about 156 freezing nights a year. Drain the water line and pan and cover the cooler before then.
The Denver water supply includes mountain snowmelt collected from the South Platte and Colorado River watersheds, generally lower in hardness than desert water but still capable of leaving seasonal buildup.
Highlands, Baker, Capitol Hill, Park Hill, Washington Park, Sloan's Lake, and other parts of Denver County.
Denver has dry summer afternoons and a shorter season than the desert Southwest. Spring startup and fall shutdown matter because freezes, hail, dust, and quick weather swings can all affect an evaporative cooler.
Denver lists evaporative cooling units under mechanical quick permits for single-family and duplex work. For a new unit, full replacement, rooftop work, or changed equipment location, ask whether the estimate includes the mechanical permit and Denver contractor licensing requirements.

Quick answers for homeowners in Denver.
Hot afternoons in Denver average around 90°F with about 30% 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 Denver.
With water around 5 gpg and about 105 cooling days a year, visually inspect the pads before peak summer and again 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 5 grains per gallon (gpg), Denver 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.
