For this job I performed a super tune-up. I noted the blower capacitor and the fan capacitor or both out of tolerance. Low tolerance on capacitors cause extra stress on the motors they are running with them and can cause premature failure on the motors themselves. I noted a severely burnt primary electrical control unit, recommended replacing due to burnt weldings that can get stuck and fail overtime. I noted a faulty thermal expansion valve starving the compressor for refrigerant. Refrigerant levels were within normal limits. I recommended replacing the thermal expansion valve where if it is not done it will cause extra strain on the compressor and can cause failure, it will also cause low efficiency when running the unit. I recommended adding insulation the home does have little to no insulation I gave a minimum price but homeowner is not interested in having insulation added. I recommended ceiling the ducts to the supply plenum and the plenum to the furnace due to air leakage caught
