Performed AC diagnostic on 2 1990s York condensing. Upon my diagnostic I found that the left side condenser of home was not working and right side was. Upon Further investigation many points and concerns were addressed. 4 ton left side of home- 1. Secondary motor control was blown on hermetic And fan side terminals 2. High voltage really burnt on contact points 3. Compressor pulling incredibly high amps 4. Condenser fan motor completely rusted and over amping 5. Compressor saver kit added to reduce start up amps of compressor 6. System contained R22 which is a completely phased out refrigerant as of January 1, 2020 4 ton right side- 1. Compressor pulling high amps on runtime. 2. Secondary float switch is being tripped due to primary clog 3. Compressor failing on start up amps adding compressor saver kit 4. System contains R22 refrigerant as well 5. Fan motor also not in good condition due to rust
