No. They’re programmable thermostats so you set them to what levels you want during the time periods you want. It’s not like I’m going to freeze at this time of year if I go away, so it doesn’t matter if it’s set to cool. I usually set my temp to around 70 for both heating and cooling. It just feels the best. Some days if it’s one of those real cold windy days I’ll override a bit warmer and conversely if it’s one of those hot/humid days in the 90s I’ll drop the temp a few degrees to help the system a bit.
Thermostats have 3 settings. Heat/Cool/Off.
Heating system is radiant via oil and cooling system is electric with air handler in attic and condenser outside. It’s a 2 zone system for both, 1st floor and 2nd floor.
Another reason to use AC at night and not have windows open, is pollen. Don’t care for a house full of it and have 3 people who have seasonal allergies sneezing all day from it. A little open windows during the day for a bit is ok but not good for the sinuses.
Yeah, my entire lawn/yard is in need of professional help. Need ps dethatching, aeration, denser grass, less weeds, beds, edging, mulch. You name it, it needs it.
