A/c repair call for the upstairs system. Found system with almost no refrigerant indicating a major leak. Performed leak search and found leak in both condenser coil and evaporator coil. Due to age and cost of repair, recommend upgrading system to a more reliable, more efficient system. At bare minimum, outdoor unit and evaporator coil will need to be replaced. Sending Garrett out for a consultation. Thank you so much for your business today!
