Other Factors to Consider
Climate & Humidity
In dry climates (under 40% humidity), evaporative coolers are the most efficient choice. In humid climates like Houston (60%+ humidity), spot coolers or misting fans work better.
Indoor vs. Outdoor
Enclosed spaces need spot coolers with exhaust ducting. Open-air spaces do better with evaporative coolers or misting fans that don't require exhaust.
Ventilation
Evaporative coolers require good airflow — they push hot air out while pulling cool air in. If your space is sealed, a spot cooler is the better choice.
Ceiling Height
Spaces with high ceilings (20+ ft like warehouses) may need larger or additional units. CFM (cubic feet per minute) ratings matter more than square footage alone in tall spaces.
Still Not Sure?
Use provider input to review the equipment options and confirm final sizing. Request quotes from available local providers.
