An air conditioning of 5,000 BTU can actually cool a room that measures from 100 to 150 square meters, according to a basic standard of the industry. So the best way to choose an air conditioning capacity is to start with the square images of the rooms, and then make adjustments if necessary for the specific space.

Ductless units only require a very small hole to drill into the wall, making them less vulnerable to air leaks and safety issues. In addition, they are less visible and noisy. They are also extremely energy-efficient.

An air conditioner of 5,000 BTU is the best option to cool a room of less than 150 square feet, while an air conditioner of 6,000 BTU is designed to cool a room of 150 to 250 square feet. If your room size is between 150 and 250 square feet, an air conditioner of 6,000 BTU will cool the room effectively.

In general, an air conditioner from 5,000 to 6,000 BTU can cool between 100 and 300 sq m. Seven thousand to 8,200 BTU units are suitable for cooling 250 to 550 sq m, while models from 9,800 to 12,500 BTU cool to 950 sq m.

The bottom line. A Daikin air conditioner is a great option if its main objectives are reliability, quality and accessibility. They also have great energy saving options, but their cooling systems do not have most of the new features and technologies that some manufacturers offer.
