Completed cooling tune up, cooling wire on the air handler going to the condenser was loose not allowing to call for cooling on condenser. Tightened it back up & unit began cooling again. While checking pressures the breaker on the air handler to the condenser was tripped. Reset it & let the home owner know about it & if it continues we’d have to change out that breaker. Other than that everything checked out good. No other issues to report.
