AC precision tune up. Clean and tune up AC; cleaned condenser coil, checked all outdoor electrical components, tested indoor air flow, checked refrigerant levels, and tested overall AC operation. Found the pipe insulation had deteriorated and fell apart closer to the outdoor unit. Replaced to increase cooling efficiency. Lastly found the blower wheel to be extremely dirty. This will decrease airflow and could cause major issues. Pulled and cleaned he blower to increase airflow and also increase the efficiency of cooling inside the home. All other recommendations declined at this point. With age and efficiency loss, replacement would be encouraged soon.
