What You Need to Know When Shopping for a Room Air Conditioner
Don’t wait until it’s sweltering to think about buying a new room air conditioner—buy now and be ready when the first heatwave hits. Before you shop, consider these points to be sure you get the right air conditioner for your space.
Window Units Vs. Portable Units
Figuring Room Size and BTUs
Air conditioner cooling is rated in British Thermal Units, or BTUs. To see what size AC unit you need for your space, measure the room lengthwise and widthwise. Multiply the two measurements and you have your room’s square footage. If the space is open (not separated by a physical door) you may need to calculate two room sizes together to find the most efficient air conditioner to cool your total area.
Next, divide the total square feet by 20—it takes about 20 BTUs to cool a square foot of home space. The result should tell you how many BTUs you’ll need the room air conditioner to be rated to keep your space cool. Most air conditioners supply BTU ratings in the thousands (e.g., a 6,000 BTU window air conditioner), so you will need to round up when shopping for a unit.
Haier offers window AC and portable room air conditioners that produce between 5,000 and 23,500 BTUs, so you’re sure to find a unit to cool your space perfectly.
