Tech preformed CMA INSPECTION on 11 Split Systems and 3 Mini Split Systems. Mini Split System #2 is still waiting on electrician to convert current disconnect from 120v to 240v. Tech checked with office and electrician is scheduled but did not give date. Tech recommends replacement of Condenser Fan Motor on Split Systems #1 and #2. Tech has attached estimates to invoice for cost of repairs. Tech also attached estimate for Split System #7 which is in need of a Fan Capacitor.
