The bare minimum basic repairs to get the system running today. Found outdoor unit not coming on but making humming sound. Found bad capacitor and dirty condenser coil. Replaced capacitor and cleaned condenser coil. Recommend adding flood protection to the system. There is no drain pan under the unit and no water safeties on drain line or near bottom of the unit to stop potential water damage. Checked refrigerant levels. System has 17 degree difference. 69 supply and 86 return. System is short on return but is in garage closet.
