Verdict

The TROTEC PAC 3500 SH is a versatile 4-in-1 mobile air conditioner designed for rooms up to 46 m² (115 m³), delivering a powerful cooling capacity of 3.5 kW (12,000 Btu/h, Energy Class A) and a heating capacity of 2.9 kW (Energy Class A+). Featuring a maximum air flow rate of 420 m³/h, a 3.25 l/h dehumidification capacity, and an eco-friendly R290 refrigerant, its main pros include efficient year-round temperature regulation (17°C to 30°C), a convenient automatic thermostat mode, a night mode with turned-off LEDs, and a practical 24-hour timer. However, notable cons are its relatively high weight of 34 kg, which limits effortless mobility, a maximum noise level of 54.5 dB(A) that might still be noticeable in completely silent rooms, and the requirement of an exhaust hose setup via a window kit.
