Evaporative cooler vs air conditioner: which one fits your home?
Choose Evaporative cooler for dry climates; Air conditioner for humid climates. The right choice depends on the outdoor relative humidity during the cooling season, open floor plans, and hallways and multiple bedrooms.
| Factor | Evaporative cooler | Air conditioner |
|---|---|---|
| dry climates | PNNL (2022): "Evaporative coolers work best in dry climates where the outdoor relative humidity during the cooling season is low." | PNNL (2022): "In humid climates choose standard mechanical air-conditioning and heat pumps, which also offer the advantage of de-humidification." |
| humid climates | PNNL (2022): "Evaporative coolers work best in dry climates where the outdoor relative humidity during the cooling season is low." | PNNL (2022): "In humid climates choose standard mechanical air-conditioning and heat pumps, which also offer the advantage of de-humidification." |
| Humidity | PNNL (2022), direct evaporative coolers: "Unlike standard air conditioning, direct evaporative coolers increase rather than decrease the humidity in the air." | PNNL (2022): "In humid climates choose standard mechanical air-conditioning and heat pumps, which also offer the advantage of de-humidification." |
| Water reservoir upkeep | PNNL (2022): evaporative coolers "require regular maintenance to keep the water reservoir clean". | no official figure |
| Compact homes with open floor plans | PNNL (2022): "Central-location installations work well for compact homes with open floor plans." | no official figure |
| Larger houses with hallways and multiple bedrooms | PNNL (2022): "Ducted systems are needed for larger houses with hallways and multiple bedrooms." | no official figure |
| Roof-mounted installation | PNNL (2022): "Roof-mounted systems can be difficult to access for maintenance and can lead to leaks in the roof." | no official figure |
| Air distribution | PNNL (2022), incoming air from an evaporative cooler: "is not recirculated inside the house but is blown through the house and must have a way to exit." | no official figure |
| An alternative air exit | PNNL (2022): "Alternatively, ceiling exhaust vents can be installed." | no official figure |
