Tech performed CMA full service on 2 gas package units, 1 air make up, and 4 exhaust fans. Upon inspection tech found 2 compressors out of 4 out of service on gas pack #2. Tech also found all 4 fan capacitors reading low. Due to the age and condition of this unit tech recommends replacement. Both systems are operating in heat mode normally. The air make up and exhausts are operating properly. Tech has attached system performance reports to this invoice.
