Take apart a Classic America inverter heat pump, one layer at a time, and see what does the work.
31.6 in wide, 8.3 in deep, 27 dB(A). Everything that cools the room sits behind this panel.
It swings up without tools, because the next layer needs cleaning every few weeks.
Rinse, dry, slide back. Clean filters keep airflow and efficiency where they should be.
Refrigerant expands inside the copper tubing and pulls heat out of the room air passing over the aluminum fins.
The barrel fan draws air through the coil and pushes it out across the louver, evenly and quietly.
The board reads the room sensor and talks to the outdoor inverter, the remote, the Tuya Smart app and Alexa.
The indoor unit only moves air. The outdoor unit is the engine, and it is what makes an inverter heat pump different from an old on-off compressor.
Compressor, condenser coil, fan and inverter board in one weather-rated cabinet.
A variable-speed compressor ramps up and down to hold the setpoint instead of cycling at full power. That is where the efficiency comes from.
The coil wraps the cabinet so the fan can push the room's heat into the outside air.
Refrigerant carries heat between the two units through the line set that ships in the box.
A reversing valve flips the cycle. The same loop that cooled the room in July warms it in January.
Answer a few questions about the room and get the BTU you need, matched to a model.
