What is the difference between evaporative coolers and air conditioners?

Air conditioning units utilize refrigerants and cooling coils to circulate and cool your space, recycling the air in the process. Evaporative cooling units, also known as swamp fans, offer significant advantages in maintenance and energy efficiency. Ideal for dry, hot climates, evaporative cooling fans take in hot air and provide a continuous stream of fresh, cooled air through evaporation.

At what temperature and humidity do evaporative coolers become ineffective?

Evaporative coolers are ideal for environments with temperatures above 80°F and humidity levels below 50%. Running an evaporative cooler when humidity exceeds 50-60% is not recommended. Need more help? Contact one of our equipment experts for further guidance.

Can you run evaporative cooling fans all day?

Yes, you can leave an evaporative cooler running 24/7. These units utilize low-power fans designed to operate continuously without issue, ensuring sustained cooling performance.
