Arrived for the upstairs unit not cooling properly. Our client had replaced thermostats and fuses without any luck of turning the unit to cool. I immediately went outside and found a failed contactor. I further tested the capacitor and ensured it was still good. I showed my findings to our client and she elected to replace the contactor and join our maintenance plan for both units. I made sure the unit was cooling properly with a 20° drop and our client informed me she leaves the unit off upstairs unit she wants it cool. I recommended that she leave the thermostat on at a 77°/78° set point so that the unit does not have to work extra hard to cool the upstairs space. We also discussed moving the chair in front of the return grill just a little to let the unit breathe better. When testing the unit I found the compressor start amps to be very high. Over manufacture specifications, I sent an estimate for a hard start kit that will help bring the start amps down and help extend the life
