We've ben told to not use the automatic setting on our climate control system. The rational was that the when the outside temperature was high the cooling would be cranked up and when the temperature dropped, the system would have to crank way up to heat the house.

This make no sense to me as if we have the temperature set on 75, the AC would shut off once the temp went below 75. If we have the heat set on 72, then the heat would come on once the inside temperature dips below 72.

Has anyone else ever heard anything like this?

Makes no sense to me either, we use the automatic all the time, UNLESS we have the windows and sliders open in nice weather. When we do this I typically turn the A/C system off until we close the windows and sliders.

We have been here since December 28 and neither our heat or A/C has turned on yet. The A/C is set at 78, the heat at 62, and the windows and sliders are always open. It’s been very comfortable, especially the cooler sleeping temperatures the last couple of nights. I love not having the energy sucking HVAC system kicking on this time of year.

We use auto-mode -- 60-80 -- and we self-monitor via Ecobee app when away from home. When on-site we adjust accordingly.

I use the AUTO setting all the time, but my Carrier thermostat will not allow the cool setting to be less that 4 degrees higher than the heat setting. So, if cool is set on 78, then heat must be 74 or lower. Whoever told you to not use the AUTO setting was wrong.
