Verdict

The Pro Breeze PB-AC04 is a 7,000 BTU 3-in-1 portable air conditioner designed to efficiently cool, fan, or dehumidify small to medium spaces up to 16 m² (172 sq. ft.) down to temperatures of 16°C. Operating with eco-friendly R290 refrigerant, the compact 19.5 kg unit features a Class A energy efficiency rating with a consumption of 0.778 kWh, a 0.6L internal water tank, two fan speeds, a 24-hour timer, and manual oscillation (90° horizontal and 140° vertical). Main advantages include quick cooling performance, a dedicated energy-saving sleep mode, convenient digital LED and remote control operations, and the inclusion of two easy-to-install window venting kits suitable for both sliding and hinged windows. However, notable drawbacks include a relatively high operational noise level of 53–54 dB that can disrupt light sleepers even in night mode, a heavy chassis that makes manual transport up stairs difficult, and a lack of automated motorized oscillation.
