Upon arrival system was on cool and thermostat was responding but system was not cooling Went into attic just to assure that thermostat was calling and 24 volts were going to outdoor unit After confirming I went to outdoor unit and removed panel First thing I checked was contactor to see if I had high voltage and 24 volts which I did Checked disconnect just in case and it's in good condition Checked capacitor and noticed it was out of tolerance on both herm and fan Recommended capacitor replacement and home owner agreed I did not have a 45/7.5 dual run capacitor which unit was rated for so I replaced it with 45 and 7.5 single run caps After replacing capacitor and flipping disconnect back on unit kicked on Checked deltas in attic to assure proper cooling and system had a perfect 21° Delta. System was left on cool at departure and homeowner said he would set thermostat to preferred temperature himself.
