Window air conditioner install and support bracket

Secure the unit so it cannot fall, give it the slight outward tilt the manual specifies (some models have a sloped base pan and need none), seal the side panels, and plug directly into a suitable outlet. Larger or heavier units should have an exterior support bracket.

Most PTAC no-cool calls are airflow (filter, coils), a wrong control setting or a failed compressor start component. Rule those out before suspecting the sealed system.

PTAC not heating (electric heat or heat pump)

PTACs heat with electric strip heat, a heat pump, or both. Heat pump models switch to strip heat in cold weather. Check settings, then the heater element and its limits, then the reversing valve.

Most PTAC brands store fault codes that can be shown with a button combination on the control (for example GE Zoneline uses a MODE + another key sequence on some models). Read the active code, fix the cause, then clear it.
