家中有小朋友,最緊要空氣清新。呢部有UV-C殺菌真係加分!BBE師傅安裝得好小心,仲幫手清走舊機。The cooling is very stable, kids sleep much better now. Highly recommended for families!

The R32 inverter tech is quite efficient. My electricity bill dropped slightly compared to my old unit. Very quiet at night, no more 'clack' sound when compressor starts. Smooth delivery by BBE team.

Replacing my old unit with this Frostar. The inverter tech makes it so much quieter at night. Buying from BBE was smooth and hassle-free. Good value for money.

Fast delivery within 2 days. 5-year compressor warranty gives me peace of mind. The R32 refrigerant is also more eco-friendly. Great purchase at BBE.
