10 Best Ac Coolers 2026 in the United States

The Whirlpool 24,000 BTU window air conditioner is designed to cool large rooms up to 1500 square feet, making it a solid choice for spacious living rooms, apartments, or bedrooms. It uses inverter technology, which adjusts the motor speed to save energy by running only as much as needed, helping to avoid wasted power. This unit offers three fan speeds and a dehumidifying function that removes moisture from the air, improving comfort on humid days. A notable feature is its mute mode that reduces noise to about 43 decibels, which is quieter than many other models, allowing for peaceful naps or TV time without much disruption. The washable filter with a clean filter alert is convenient for maintenance and helps the unit keep running efficiently over time.

It also includes practical controls like a remote, sleep mode, an eco setting, and a programmable timer, giving you good control over your cooling preferences. On the downside, the energy efficiency rating is on the low side with only 1 star, meaning it might use more electricity compared to more efficient models, which could affect your energy bills. The noise level at normal operation is around 52 decibels, which is average but might be noticeable in very quiet environments. Installation requires a suitable window size, and the unit is fairly heavy at over 90 pounds, so setup might need two people.
