Pete noticed the geo blower was moving a lot more air after the thermostat was replaced. I cycled the unit. Found the blower motor would run in its highest speed for a 1st stage heat call. I checked the thermostat programming. Found we didnâ€™t set up the thermostat properly. I adjusted the back up heat differential to 5 degrees. Also turned off the finish in high heat setting. Cycled the geo. Itâ€™s operating properly at now. There is no charge for this visit.
