During a standard split-type air conditioner installation, the technician begins by identifying the optimal placement for both the indoor and outdoor units, then drills a hole through the wall to route the refrigerant lines, electrical wiring, and drainage pipe connecting the two units. The indoor unit bracket is mounted securely on the wall, the unit is hung in place, and the refrigerant lines and electrical connections are made before the system is vacuumed to remove moisture and air from the lines. The outdoor condenser unit is then secured in its designated location, the refrigerant charge is verified, and the system is tested at multiple settings to confirm that it is cooling properly and that there are no leaks or electrical issues before the technician completes the job.
