Maybe not an issue?
Good morning all,
Yesterday I noticed my thermostat was low on battery power, after the unit was struggling to get down to 75, it was on 78. Low battery was flashing, I changed them and the thermostat is still not working correctly. Maybe I’m wrong? The air coming out of my vents is cold. Return has a new filter. It did finally get to 75 and stay but it took much longer than it did just yesterday. Thermostat is a few years old now. Basic Honeywell.
Is it a bad thermostat? Is the unit messing up?
