Customer explained water leaking from furnace when ac would run. Ran ac and found ice on refigerant lines. Removed and replaced dirty filter with clean one to ensure good airflow. Recommended we conduct a tune up to verify proper operation. Perfomed an 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 system to be low on R22 refigerant. To get unit up and cooling properly, would have to charge with refigerant, add a leak seal to attempt at stopping refigerant leak, and install locking caps. Electrical components and outdoor unit showing age and are in need of replacement. Motor starter very burnt. Can cause poor electrical connections and lead to unit failure. Motor booster is testing out of manufacture rating and could also lead to unit failure. Customer did not want to make repairs today. Customer purchased new unit over the
