Is a 10,000 BTU AC the Right Size?
These units are rated for 350-450 square feet. If the room is in that range, the unit should adequately cool and dehumidify it, especially if it’s on the low end of the range.
If it’s close to 450 square feet and especially hot, you might want to consider a larger unit:
- Does it face west and get really warm in the afternoon?
- Is it on an upper floor where the heat rises?
- Does the room have 10-foot ceilings?
- Is it a kitchen, and the oven or stove is often in use?
Any of these factors could mean that a 12,000 BTU window air conditioner is a better choice. With a window AC, it is OK to go up one step to ensure the unit will adequately cool the space.
