Is there a through-the-wall air conditioner that is a heat pump?

Which wall units heat as heat pumps, which sleeve each one fits, and the outdoor temperature at which each hands over to its electric heater.

The short answer

Yes. 7 through-the-wall heat pumps we list are in stock, from $1,049 to $2,629: 5 PTACs for the 42-inch PTAC sleeve and 2 Friedrich Kuhl units for a window or Kuhl's own sleeve. Below about 40°F outside their heat pumps stop: 6 switch to an electric heater, which keeps the room warm at what any electric heater costs (the 115-volt Kuhl lists a back-up heater only in its newest revision). Of the other 14 slide-in wall units with heat we list in stock, 10 heat with an electric coil and 4 do not state enough to tell.

Each is a heat pump by its own listing, not by the words "with heat". "Electric heat below" is the outdoor temperature its source gives for the switch to the electric heater, and an hour's cost is its stated heat-pump draw at the US average electricity price.

When a wall heat pump switches to electric heat

Below that temperature each one heats like a coil, so where winter days sit below freezing, most of the saving comes in spring and fall. For heat that stays efficient in real cold, a mini split certified for its output at 5°F is the comparison to make.

Frequently asked

Do through-the-wall heat pumps work in cold weather?
Not with the heat pump. Friedrich says its WallMaster heat pump switches to its electric heater at about 35°F outside, Sylvane lists Friedrich's ZoneAire PTAC heat pumps switching below 40°F, and Friedrich's Kuhl heat pumps stop near 40°F. Below that they heat with the electric heater, so they keep working in the cold, at the cost of any electric heater.
Is a through-the-wall heat pump worth it?
Above its switch-over temperature, yes: the Friedrich PZH07K3SC makes 6,000 BTU of heat for about $0.09 an hour at the US average electricity price, where an electric coil making the same heat would cost about $0.32. And it need not cost more to buy: At Sylvane, the 12,000 BTU heat-pump model PZH12K3SC is $1,129 and the electric-heat PZE12K3SC is $1,159: $30 less for the heat pump. In a region that is below 35 to 40°F most of the winter, the saving is smaller, because the unit spends those days on its electric heater.
What is the difference between a PTAC and a through-the-wall air conditioner?
A PTAC (packaged terminal air conditioner) fits a 42 x 16 inch sleeve and runs on 208/230 or 265 volts; it is the unit under hotel and apartment windows, and most are sold with heat. A through-the-wall air conditioner slides into a smaller sleeve, about 24 to 27 inches wide, and most run on 115 or 230 volts. The two sleeves are not interchangeable, so the sleeve already in your wall decides which kind you can buy.
Will a heat pump fit my existing wall sleeve?
Only if one is made for that sleeve. A 42-inch PTAC sleeve takes any of the PTAC heat pumps above that fit its brand's sleeve. In the smaller sleeves, the heat pumps we list are Friedrich's: the WallMaster for its 27-inch sleeve and the Kuhl for a window or Kuhl's own sleeve. The sleeve finder on our through-the-wall page lists which range fits each sleeve width.
Which brands make through-the-wall heat pumps?
Of the brands we list, Amana, Friedrich, Frigidaire. Friedrich makes them for both sleeve families (WallMaster and Kuhl slide-ins, ZoneAire and Zone Premier PTACs); the others are PTACs. Every in-stock slide-in wall unit from the other brands we list heats with an electric coil or does not state how it heats.
