I have a York 5 ton A/C system with a gas furnance. The A/C tech that recently perform a Preventive Maintenance Yearly Service told me that my compressor was not operating efficiently based the RLA spec to the actual ampere reading. The RLA is 28.9 and the ACTUAL reading was 22.6 amps. He said that indicated the compressor has tight windings and would not last much longer. He also said the ACTUAL ampereage reading should be half of the RLA, which in this case would be 14.45 amps.
My question is: Is would he stated a true statement? Please state the facts as to why it is or is not true. I would greatly appreciate some factual basis so I can make an educated decision as to whether or not to purchase a NEW system or whether I can wait.
