Residential air conditioners can be divided into 3/4HP, 1 HP, 1.5HP, etc.

The number of horsepower represents its cooling capacity; the larger the area of the room, the number of horsepower will increase accordingly. But the air conditioner cannot be selected based on the area alone. The cooling effect may be affected by different external factors, including the size of the window, the height of the floor, the degree of sunlight exposure, the number of people in the room, etc.

The following information is for reference only and it should be increased or decreased according to actual conditions.

Residential air conditioners on the market can be divided into 2 categories: "non-inverter" and "inverter". The biggest difference is the way the compressor operates. The fixed-frequency air conditioner will stop the compressor when the room temperature drops to the set temperature, and restart when the room temperature rises; the inverter air conditioner will keep running, and when the room temperature drops to the set temperature, the compressor will switch to low-frequency operation mode.

According to a test conducted by Consumer Council in 2016, it was found that the inverter type air conditioner has higher cooling energy efficiency than the traditional fixed-frequency one, saving about 40% of electricity throughout the year.
