During the scorching summer heat, an air conditioner is an essential item for your home life. However, faced with the dazzling array of AC products on the market, are you confused about how to choose the right AC capacity for your home? Don't worry! The New York Blue Sky On-Site Repair Team will provide a detailed analysis of the matching relationship between AC capacity and room area, helping you make an easy purchase and enjoy a cool summer!
Matching Standards for AC Capacity and Room Area

According to standards set by the national refrigeration department, the matching relationship between AC capacity and room area is as follows:
- 1 HP AC: Cooling area of 20-30 square meters
- 1.25 HP AC: Cooling area of 30-50 square meters
- 1.5 HP AC: Cooling area of 50-60 square meters
- 1.7 HP AC: Cooling area of 55-70 square meters
- 2 HP AC: Cooling area of 65-80 square meters
- 3 HP AC: Cooling area of 80-100 square meters
You can refer to the above standards based on the actual area of your home to choose the appropriate AC capacity.
Besides Area, These Factors Also Matter!
In addition to room area, the following factors also affect the choice of AC capacity:
- Room Orientation: South-facing rooms receive ample sunlight and require an AC with slightly higher capacity.
- Room Insulation: Well-insulated rooms can opt for an AC with slightly lower capacity.
- Number of Occupants: Rooms with more occupants require an AC with slightly higher capacity.
- Indoor Heat Sources: If there are many heat-generating appliances indoors, such as computers, TVs, etc., an AC with slightly higher capacity is needed.
Relationship Between AC Capacity and Power
- 1 HP ≈ 1 horsepower ≈ 735 watts
- 2 HP input power ≈ 1470 watts
AC capacity does not refer to cooling capacity but rather to the power consumption of the AC. Cooling capacity is estimated based on the AC's power consumption. Generally, a 1 HP AC has a cooling capacity of about 2500W (i.e., model 25), a 1.5 HP AC has a cooling capacity of about 3500W (i.e., model 35), and a 2 HP AC has a cooling capacity of about 5000W.
