FAQ

Q: What is the ideal size for a wall air conditioner?

A: It depends on the size of the room. For small rooms, an air conditioner with a capacity of 5,000-6,000 BTUs is sufficient. Larger rooms will require higher BTU capacities.

Q: Can a wall air conditioner be installed without professional help?

A: It is recommended to have a professional install a wall air conditioner, as it involves cutting a hole in the wall and properly sealing it. Improper installation can lead to air leaks and reduced efficiency.
