For this eval I should have to the home and the homeowner stated her unit was blowing out hot air when she had the thermostat set to 73° f. This was a package unit so I went to the condenser and tested the capacitor first, then gauged up where I had abnormal superheat and subcool. I went inside and used my heat gun and measured 110° f blowing out of the vents when it was 79° in the house. After jumping R,Y,G,O the system switched to cooling. After undoing that jump the system went back into heating, which led me to believe the thermostat was bad. Due to this homeowner being P&L I swapped the thermostat and programmed it accordingly. The system went into a 5 minute delay and then turned on and went into cooling. I left with the thermostat set to 78°. This customer switch to the new home and budget protection plan so her service fee was waived today.
