The OLMO 12,000 BTU PTAC with Electric Heat is a one ton PTAC with a 3.5 kW electric heat strip, a wireless smart kit, a remote, a dehumidifier function and R-32 refrigerant on a 230/208V, 20A plug. For more models, see our Through-the-Wall Air Conditioners with Heat page.
Our Verdict
This OLMO is the PTAC to buy when purchase price matters most but you still want app control. It costs noticeably less than most name brand units of the same size and includes a smart kit that many of them do not.
It heats with an electric strip rather than a heat pump, so heating costs more in mild weather. If you heat the room for months each year, a heat pump model will pay back its higher price.

Design
The chassis measures 21 by 42 by 16 inches, weighs 112 pounds and is built for a standard 42 inch sleeve. The sleeve and exterior grille are required for new installations and are sold separately.
OLMO describes the operation as whisper quiet and pitches it for bedrooms, sunrooms and senior living rooms. It is charged with R-32 refrigerant.
Controls
You can use the digital panel, the included remote or the OLMO app through the wireless smart kit. Modes include cooling, heating, fan and a dehumidifier function for damp summer days.
It runs on 230/208V single phase power and comes with a 20A plug with a reset breaker. OLMO asks you to check that you have the right receptacle before ordering.
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 heat pump PTACs such as Klimaire’s or the Distinctions by Amana, the OLMO costs less up front and adds a smart kit, but its electric heat costs more to run in spring and fall.
Against Cooper & Hunter’s smart PTAC with heat, the OLMO offers similar controls and electric heating, and it lists its weight.
