I completed diagnostics and found that only the fan was operational. I checked dual capacitor and it was out of spec. I need to make repairs to further troubleshoot AC. I quoted repair and it was authorized and performed. the suction pressure is not to par and Superheat is too high. The system is low on r22 refrigerant and is also undersized per sq ft of home. The system has a leak, high probability of leak being in the evaporator coil. Based on age (19 years old), having the old outdated refrigerant, cost of seen and unseen repairs, not having a warranty, lack of efficiency and condition I recommend planning on replacing system in near future. Spoke to Keith, via phone call, he was not wanting to go with a top off of refrigerant or go over replacement options at this time. Wanted a second opinion. The system was operational when leaving.
