PTAC heat pumps
A PTAC (packaged terminal air conditioner) heat pump is the self-contained, through-the-wall unit you see in hotels — it heats and cools one room.
What is a PTAC heat pump?
A PTAC (packaged terminal air conditioner) heat pump is a single, self-contained unit that mounts through an exterior wall — the type common in hotels, apartments, assisted-living and sunrooms. It both cools and heats a room, using a heat pump with electric resistance backup for cold weather. A "through-the-wall heat pump" is the same idea.
Cost and where they are used
PTAC heat pump units typically run $700–$1,500 plus the wall sleeve and a dedicated circuit. They are popular where you need per-room, replaceable, no-ductwork conditioning — hospitality, multi-family, additions and sunrooms. Each unit serves one room.
PTAC vs mini-split
| PTAC | Mini-split | |
|---|---|---|
| Install | Through-wall sleeve, self-contained | Outdoor + indoor units, line set |
| Efficiency | Lower | Much higher |
| Noise | Louder (compressor in the room) | Quiet (compressor outside) |
| Best for | Hotels, easy replacement | Homes, efficiency |
For a home, a ductless mini-split is quieter and far more efficient; a PTAC wins on simple replacement and lower upfront cost.
Frequently asked questions
What is a PTAC heat pump?
A packaged terminal air conditioner with a heat pump — a self-contained through-the-wall unit (like in hotels) that both heats and cools one room.
How much does a PTAC heat pump cost?
Usually $700–$1,500 for the unit, plus a wall sleeve and a dedicated electrical circuit.
PTAC vs mini-split — which is better?
A mini-split is quieter and much more efficient; a PTAC is simpler to replace and cheaper upfront, which is why hotels use them.
