During the process of choosing an air conditioner, users often wonder what a 2-horsepower air conditioner is and what size room it is suitable for. To answer all these questions, please refer to the following article by Mytour Blog, along with some suggestions for the best-selling products that are currently most favored by customers.
What is a 2-horsepower air conditioner?
What is a 2-horsepower air conditioner? This is a type of air conditioner with a 2-horsepower operating capacity, equivalent to 18,000 BTU. Thus, the “horsepower of an air conditioner” is also called horsepower, which is a unit of the operating capacity of the air conditioner motor (not the power consumption/electricity consumed by the device).

Is a 2-horsepower air conditioner effective at cooling? What area is suitable for a 2-horsepower air conditioner?
To select a 2-horsepower air conditioner with the appropriate capacity for the room area, users apply the following calculation formula: Air conditioner capacity = area x 600BTU. Accordingly, for every 1m2 of room area, a machine with a capacity of 600BTU is required. From this, you can easily calculate the horsepower air conditioner suitable for your living space. According to this formula, a 2-horsepower air conditioner will effectively cool a room with an area of 30m2 (18,000 : 600 = 30). Manufacturers advise customers to use devices with capacities suitable for the room area to ensure stable operation and avoid wasting electrical energy.

Recommendations for air conditioner capacities suitable for room sizes
Below are helpful suggestions to help you easily find the air conditioner model with the appropriate operational capacity for your room size:
- Room with a maximum area of 15m2, volume less than 45m3: Preferably use an air conditioner with a 1-horsepower operating capacity (equivalent to 9,000BTU).
- Room with an area from 15 – 20m2, volume less than 60m3: Preferably use an air conditioner with a 1.5-horsepower operating capacity (equivalent to 12,000BTU).
- Room with an area from 20 – 30m2, volume less than 80m3: Preferably use an air conditioner with a 2-horsepower operating capacity (equivalent to 18,000BTU).
- Room with an area from 30m2 – 40m2, volume less than 120m3): Preferably use an air conditioner with a 2.5-horsepower operating capacity, equivalent to 24,000BTU.
