We just updated the air conditioners guide with our recommendation for a portable unit, the LG LP1214GXR. We also had to make a correction to the piece: we’d said Amazon and Lowe’s sold the same version of our main Frigidaire pick. Turns out Lowe’s sells the same AC but without the handy built-in thermometer in the remote or an ionizing filter. If you need those things, go with Amazon. If you can live without them, you can save money on our pick at Lowe’s.
