The Klimaire 9,000 BTU PTAC Heat Pump is a small-room PTAC heat pump with an 11.4 EER, 7,900 BTU of heat pump heating, a 3.5 kW backup heater, a wireless remote and a drain kit. For more models, see our Through-the-Wall Air Conditioners with Heat page.
Our Verdict
This Klimaire is the PTAC to buy for a bedroom, a hotel room or a small office. It is sized to avoid the short cycling that oversized units cause, and its 11.4 EER is among the best efficiency ratings we found at this size.
Heat pump output is modest in cold weather, so the backup heater will do much of the work on the coldest days, and Wi-Fi is an option rather than standard.

Design
Klimaire built this R-32 series to slide into most standard 42 by 16 inch wall sleeves, so it can replace an older unit from another brand. It weighs 104 pounds.
A drain kit comes in the box for piping condensate away from the wall. New installations need a wall sleeve and rear grille, which are not included.
Controls
Cooling, heating and fan-only modes cover the year. You can run it from the control panel or the wireless remote, and the Wi-Fi option adds smartphone control through the app.
Power is 208 to 230V single phase through a 20A LCDI 6-20P plug. The heat pump heats in moderate weather and the 3.5 kW electric heater backs it up in colder conditions.
Placement Tips
A PTAC lives in a sleeve through an exterior wall, so placement is decided when the opening is cut. Keep the indoor face clear of beds, sofas and long curtains so the unit can draw in room air and throw conditioned air across the room, and avoid corners where the airflow hits a side wall straight away.
Outside, the grille needs open air: no shrubs, fences or stored items pressed against it. The sleeve should sit level side to side and tilt very slightly outward so condensate drains outside, and the unit needs its own 208/230V circuit with a receptacle that matches its plug.
Running Costs and Care
Running cost depends on your electricity rate, your climate and the heating type. Cooling costs are similar to a window unit of the same size, while heating is where models differ most: a heat pump uses far less electricity than an electric strip in mild weather, and every PTAC falls back on its strip on the coldest days.
Wash the front filters every few weeks in heavy use, keep the exterior grille clear of leaves and debris, and slide the chassis out once a year to clean the indoor and outdoor coils, or have a technician do it. A clean unit heats and cools faster and lasts longer.
How It Compares
Against Klimaire’s one ton heat pump, this smaller unit is better matched to bedrooms and has a higher efficiency rating.
Against Cooper & Hunter’s small inverter PTAC, the Klimaire lists its heat pump output and efficiency, while Cooper & Hunter adds an inverter and an included smart kit.
