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 blower wheel to be extremely dirty. This will cause airflow issues, larger dust build up inside the home and also put more stress on the blower motor. Also found the unit not up to state code with locking caps. These caps prevent theft, and also act as a better seal on the access ports. All recommendations declined at this time.
