Valve stem was leaking, replaced it & system needs to be charged up due to low pressure switch cutting condenser out. Changed out valve stem & charged the system up with 10lbs of 410a on the 5 ton system. Completed both heating tune ups after that & noticed the capacitor for the condenser on the 2.5 ton system was just barely below the 10% mark. Recommended changing it out but they wanted to wait until they had issues. Blower wheel on 2.5 ton system was also dirty & recommended cleaning it as well but they would think it over. Besides that everything checked out good to go with no other issues to report.
