Window Air Conditioners

Window air conditioners remain the fastest way to cool a single room: no line sets, no wall penetrations, just a properly sized unit in the window and a standard outlet. This collection includes traditional window units and casement slider models for narrow vertical windows, in 10,000 and 12,000 BTU capacities that comfortably handle rooms in the 400 to 550 square foot range.

Most models run on regular 115V household power, with electronic controls and Follow-Me remotes that read the temperature where you are sitting rather than at the unit itself. If you need year-round conditioning from one window, look at the cool/heat model with built-in electric heat on a 230V circuit.

Before you order, measure your window opening — casement and slider windows need the vertical-format unit, not a standard one — and confirm the circuit voltage for heated models. Need help matching BTUs to your room? Our team is happy to size it with you.
