How do you install a portable air conditioner to vent in a wall sleeve?

To install a portable air conditioner to vent through a wall sleeve, first, place the unit near the wall opening and ensure it fits snugly. Attach the venting hose to the exhaust port of the air conditioner, then feed the hose through the wall sleeve, securing it to prevent air leaks. Use insulation or a cover to seal any gaps around the sleeve for optimal efficiency. Finally, test the unit to ensure proper operation and airflow.
