It was crazy when I was in school & had roommates.
The people I was with and I actually had a smart thermostat & we all had access to the temperature control with our smartphones.
This was a blessing & an issue at the same time. It was wonderful because when nobody was home, we could make sure that the Heating & A/C proposal was not operating & running up the utility bills. The bad section was that we would always be fighting over the temperature control settings when we were home. I would have roommates who would have guests over & I might want some extra while trying to sleep, & they would get mad because they would guess it was too freezing in the house. Eventually, we all decided that we had to do something about this issue with the temperature control settings. The people I was with and I ended up reaching out to a local Heating & A/C corporation & we decided to have Heating & A/C zone control installed into the household, with the house being broken up into weird zones, we all were able to adjust the temperature control settings for the zone we happened to be in. This was a good solution because we no longer had to fight over the temperature control settings. The people I was with and I could have them adjusted to whatever we wanted without affecting the other parts of the house. This actually made it so we all got along better towards the end of our school experience. The people I was with and I all actually became wonderful friends & we still keep in touch to this afternoon. The people I was with and I even get-together once per year just to hang out & catch up on things.
