Which kind of AC fits the room?

It mostly comes down to the opening you already have. Start there, then check the rules and costs for that type.

  • The window opens up and down or slidesA window AC is the simplest choice. Owners electrifying heat should look at a window heat pump.
  • There's already a hole in the wall for a unitIf the opening is about 42 inches wide and 16 inches high, it's probably a PTAC. Otherwise it's likely a through the wall AC sleeve.
  • Casement windows and no sleeveA new wall opening is construction. Get advice from an architect or engineer early.
  • Window ACUsually the cheapest way to cool one room.
  • Window heat pumpCools in summer and heats in winter, with real state incentives.
  • Through the wall ACSits in a sleeve in the wall, so the window stays free.
  • PTACA packaged unit that sits in a standard wall sleeve.
