The swamp cooler (evaporative cooler, if we're being formal) is Colorado's native air conditioning. It works with our climate instead of against it: hot dry air passes through water-soaked pads, evaporation drops the temperature, and cool moist air flows through the house. No refrigerant, no compressor, a fraction of the electricity of refrigerated air.
Thousands of Fort Collins homes still cool this way, and they need seasonal care that refrigerated AC doesn't: spring startup, pad replacement, pump and float service, and proper winterization before the first freeze. We do all of it.

How evaporative cooling works
A pump lifts water from the reservoir pan to the top of the pads; water trickles down, saturating them. A big blower pulls hot outside air through the wet pads (evaporation absorbs heat) and pushes the cooled air into the house through ducts or a central vent. It works brilliantly in dry air and progressively worse as humidity rises, which is why monsoon-season afternoons are a swamp cooler's weak point.
Because the system constantly evaporates water, it also constantly adds humidity — a genuine bonus in our dry climate, and one reason many owners prefer it to refrigerated air despite the limitations.
Spring startup service
Every spring, before the first hot week, your cooler needs:
- Pad replacement: pads mineralize and mat down over a season. Fresh pads are the single biggest performance factor.
- Pan cleaning: sediment and scale scrubbed out so the pump doesn't choke.
- Pump test: verified flow to all pads, even distribution, no dry spots.
- Float valve check: proper water level; a bad float either starves the pads or overflows the pan.
- Belt and blower: belt tension and condition, blower wheel cleaning, motor amp check.
- Water line: inspected for winter damage, reconnected, leak-checked.
- First-run test: full cooling cycle verified before the heat arrives.
Skipping startup is how coolers die young. A $15 pad change ignored becomes a burned-out pump or a seized motor.
Repairs we handle
- Pump failure: the most common mid-summer breakdown. No water to the pads, no cooling. We stock replacement pumps.
- Float valve problems: constant running water or a dry pan, both fixable in one visit.
- Blower motor and belt: squealing, weak airflow, or no airflow at all.
- Water line leaks: from freeze damage or worn fittings; we repair or replace the line.
- Pad housing and louver damage: hail and sun beat up cooler cabinets; we repair or replace panels.
- Thermostat and control issues: the wall control that runs pump and blower speeds.
Fall winterization
This is the service that saves coolers. Before the first hard freeze:
- Water shut off and line drained: the supply line is disconnected and blown clear so it can't freeze and burst.
- Pan drained and cleaned: no standing water to freeze, crack the pan, or breed anything over winter.
- Pads removed: old pads come out; fresh ones go in at spring startup.
- Pump winterized: drained and protected.
- Cover installed: a fitted cover keeps snow, ice, and debris out of the cabinet all winter.
An unwinterized cooler is a burst water line and a cracked pan waiting to happen. Those are some of the most expensive swamp cooler repairs we see, and they're entirely preventable.
Swamp cooler vs. refrigerated air
Honest comparison for Fort Collins: a swamp cooler costs far less to buy and run (Xcel Energy notes an evaporative cooler can be up to 75% more efficient than a traditional central AC), adds welcome humidity, and handles our typical dry summer days well. It struggles during humid monsoon stretches, can't hit precise temperatures, and needs the seasonal maintenance above. Refrigerated AC costs more upfront and monthly, but cools regardless of humidity and pairs with real filtration. Many homes run the cooler as primary and add a small refrigerated unit or mini-split for the worst weeks. If you're weighing the switch, we'll lay out both sides (including AC installation costs) without pushing.
What affects the cost of swamp cooler service
- Service type: startup/winterization are flat-rate seasonal visits; repairs depend on the part.
- Cooler size and type: window units vs. whole-house roof or ground-mounted units.
- Roof access: roof-mounted coolers take longer to service safely.
- Parts: pumps, motors, and pads are affordable; cabinet rebuilds cost more.
