Stay Cool and Save Big: The Benefits of Evaporative Coolers in the High Desert

Evaporative coolers are a cost-effective, energy-efficient solution for cooling homes in the High Desert. They work best in our hot, dry climate, offering fresh, cool air while saving you money on energy bills. Learn how they work, when they’re most effective, and answers to common questions about these systems.

 

Why Are Evaporative Coolers Are Perfect for the High Desert Climate?

The High Desert, with its hot, dry summers, is an ideal environment for evaporative coolers. These systems use the natural process of evaporation to cool air, making them highly efficient in areas with low humidity. Here’s why they’re a great fit for our region:

Climate FactorHigh Desert ValueWhy It Matters for Evaporative Coolers
Average July High97°F (Victorville)High temps = high cooling demand
Summer Relative Humidity22–31%Low humidity = maximum cooling efficiency
Dry SeasonApril–NovemberExtended period of optimal performance
How does this help you?  
  • Evaporative coolers can lower indoor temperatures by 15–40°F, depending on the outdoor temperature and humidity levels.
  • They use up to 75% less energy than traditional air conditioning systems, saving you money on your utility bills.
When do they NOT work well?
  • During the North American Monsoon (July–September), when humidity levels can temporarily rise above 50–60%, evaporative coolers lose efficiency. On these days, a traditional air conditioner may be a better option.

Why Are They Called “Evaporative Coolers” Instead of “Swamp Coolers”?

You may have heard evaporative coolers referred to as “swamp coolers.” This nickname originated because early models could develop a musty odor or algae growth if not properly maintained. However, modern evaporative coolers have come a long way:

  • Improved materials and designs prevent odors and bacteria growth.
  • The term “evaporative cooler” is now used to reflect the advanced, clean, and efficient technology behind these systems

7 Common Questions and Answers About Evaporative Coolers

  1. What is an evaporative cooler, and how does it work?
    An evaporative cooler uses water evaporation to cool air. Warm air is drawn through water-soaked pads, where the water absorbs heat as it evaporates, cooling the air. A fan then circulates the cool air throughout your home.
  2. How much energy can I save with an evaporative cooler?
    Evaporative coolers use about 25% of the energy required by a central air conditioner, saving you up to 75% on cooling costs. They’re also cheaper to install, costing about half as much as central AC systems.
  3. How much can an evaporative cooler lower the temperature?
    Depending on the outdoor temperature and humidity, an evaporative cooler can reduce the air temperature by 5–15°F or even up to 30°F in very dry conditions.
  4. Do evaporative coolers work in humid climates?
    Evaporative coolers are most effective in areas with low humidity (below 50%). In humid climates, their cooling efficiency drops significantly, making them less effective.
  5. What maintenance do evaporative coolers require?
    Regular maintenance includes:
    • Cleaning or replacing the cooling pads.
    • Draining and cleaning the water reservoir.
    • Checking the water pump and fan for proper operation.
      Proper maintenance ensures optimal performance and prevents odors or algae growth. 
  1. Do evaporative coolers add humidity to the air?
    Yes, evaporative coolers increase indoor humidity, which can be beneficial in dry climates like the High Desert. However, this added moisture can make them less effective on humid days.
  2. Are evaporative coolers environmentally friendly?
    Absolutely! Evaporative coolers use no refrigerants (which can harm the environment) and consume significantly less electricity than traditional air conditioners, reducing your carbon footprint.
