FAQ When Buying Air Conditioners

Q1: Which is more suitable, window-type or split-type air conditioners?

Window-type air conditioners: Relatively affordable, suitable for small spaces; however, the compressor is located indoors, leading to higher noise levels that may disturb sleep. Split-type air conditioners: The compressor is placed outdoors, making it quieter, suitable for medium to large spaces or families seeking a peaceful environment; generally, they are more expensive.

Q2: How to choose the appropriate BTU rating for an air conditioner based on room size?

For room sizes of 50-70 square feet, use a 3/4 ton air conditioner; for 80-100 square feet, use 1 ton; for 110-150 square feet, choose 1.5 tons; for 160-200 square feet, use 2 tons; for 210-250 square feet, choose 2.5 tons; for 260-300 square feet, use 3 tons. This ensures efficiency and energy savings.

Q3: How to choose a more energy-efficient air conditioner based on the energy label?

Air conditioners come with mandatory energy efficiency labels as per regulations. The label's energy efficiency level is calculated based on test results submitted by importers to recognized laboratories, ranging from 1 to 5, with level 1 being the highest and most energy-saving. According to the Electrical and Mechanical Services Department (EMSD), for example, a window-type air conditioner with a level 1 label saves 11% more energy than a level 3; a level 1 split-type saves 36% more than a level 3. The more energy-efficient the air conditioner, the less electricity it consumes, helping to protect the environment and save costs.

Q4: What are the approximate installation costs for air conditioners?

Installation costs depend on the environment and model, typically including the air conditioner, piping, wiring, etc. For standard installation, costs for a window-type air conditioner range from $400 for a 3/4 ton to $500 for 1.5 tons or more; installation costs for a split-type air conditioner range from $1,270 to $2,790.
