Why Evaporative Cooling Works in Colorado
Evaporative coolers thrive in dry climates, and Colorado’s Front Range is one of the best environments in the country for them. On average, our area sees relative humidity well below 40% through most of the summer — exactly the conditions where evaporative cooling is most effective.
Compared to traditional central air conditioning, evaporative coolers use roughly 75% less electricity. They also continuously bring fresh outside air into the home rather than recirculating the same air, which many homeowners find more comfortable. For homes with existing ductwork, a whole-house swamp cooler is a cost-effective alternative or supplement to central AC.
The main limitation is on high-humidity days, typically during Colorado’s monsoon season in July and August. On those days, cooling effectiveness drops. Some homeowners run both an evaporative cooler and a central AC system, using the swamp cooler for most of the summer and switching to AC when humidity climbs.

Common Questions
Evaporative Cooler FAQs
How does an evaporative cooler work?
An evaporative cooler (also called a swamp cooler) works by drawing warm outside air through water-saturated pads. As the air passes through, the water evaporates and absorbs heat, cooling the air by 15–30 degrees before it circulates into your home. They work best in dry climates like Colorado's Front Range where low humidity allows for effective evaporation.
Are evaporative coolers a good choice for Colorado homes?
Colorado's low humidity makes it one of the best climates in the country for evaporative cooling. Swamp coolers can be highly effective on Denver metro's drier days and cost significantly less to operate than traditional central AC — typically 75% less energy. However, they are less effective on humid days, which is worth considering.
How often does an evaporative cooler need to be serviced?
Evaporative coolers should be serviced twice a year — once in spring when you start them up for the season, and once in fall for winterization. Annual maintenance includes replacing the pads, cleaning the reservoir and pump, inspecting belts and bearings, and checking water distribution. Regular service keeps the unit efficient and extends its lifespan.
What size evaporative cooler do I need for my home?
Sizing is based on the cubic footage of your home divided by two — this gives you the CFM (cubic feet per minute) rating needed. We calculate the right size during a site visit to ensure proper coverage without over- or under-sizing the unit.
Can you install a new evaporative cooler on my existing system?
Yes. We handle full swamp cooler replacements, including removal of the old unit, any necessary ductwork modifications, and commissioning the new system. We'll assess your existing setup and recommend the best path forward.
