Buying advice
What to look for in a window air conditioner
These factors change which model suits you.
Go by heat load and ignore the model name
Floor area gives you a starting estimate. Sun, people, kitchen appliances and open adjoining rooms can all shift it.
Measure the raised sash
Open the window first, then take the clear width and height. The outside trim doesn't count.
Too big can mean less comfort
If a fixed-speed unit chills the room fast, it may shut off before it has pulled out enough humidity.
Inverters can throttle back
A variable-speed compressor holds temperature with fewer hard starts and stays useful across a wider capacity range.
More window stays usable with U-shaped and saddle units
They take more effort to install. In return they can cut noise and leave part of the opening usable.
Look at your outlet before buying a large unit
A large unit may call for 230 volts, or for a circuit of its own.
