07/10/2025- I arrived on site for the follow up visit and found the thermostat suck in 5 minute delay. I started by checking the thermostat wires and found all to be securely attached. I then started checking the outdoor low voltage wires and the unit came on while I was examining the outdoor electrical section. I tested the unit startup multiple times in various ways and the unit started properly each time. My assumption is the thermostat was having an internal issue keeping itself in delay, however I cannot diagnose an issue when the unit is functioning properly. I have informed the customer to call us if the issue repeats itself. However if the issue repeats I would have whichever technician that comes back here to bringing a thermostat with them since that is most likely the issue. The unit is cooling properly at the time of this follow up visit.
