Heating and Cooling — FAQ
Do evaporative coolers work in humid climates?
Evaporative coolers perform best in dry climates under 60% humidity. Above 70% humidity, cooling efficiency drops significantly. In humid regions, consider a portable AC unit instead.
How much can I expect to pay for a quality evaporative cooler under $200?
Excellent residential units range from $80-$200. Our top pick at around $150 offers the best balance of capacity, features, and cooling power. Budget $100-$130 for solid bedroom units.
How often should I clean my swamp cooler?
Clean the water tank and cooling pads weekly during heavy use. Deep clean monthly with vinegar solution to prevent mineral buildup and mold growth. Replace pads annually.
Can I use ice instead of ice packs?
Yes, but ice packs are more efficient. Ice melts quickly and can overflow tanks, while reusable packs provide sustained cooling without mess. Most units include 2-6 packs.
What's the difference between CFM and room coverage?
CFM measures air volume moved per minute. Generally, divide room sq ft by 2 to estimate needed CFM (200 sq ft needs ~400 CFM). Manufacturers often overstate coverage—use CFM as your primary metric.
Are evaporative coolers energy efficient compared to AC?
Yes—evaporative coolers use 75% less electricity than traditional AC. Our tested units averaged 60-120 watts versus 1000+ watts for portable air conditioners, saving $200+ annually in operating costs.
