Our house is 4600 square feet not counting the finished basement. We have a two tiered heating system. Our bedroom and xs teens bedroom are on opposite ends of the house. With the upstairs thermostat set at 75 and our bedroom door closed to sleep its a full 10 deg colder in those bedrooms. Xsboy’s and xsbabys rooms in the center of the house are toasty. It would be unbearably cold set any lower.
I’ve always had the master suite at one end of the house or the other-and it was always colder in winter, hotter in summer no matter how the A/C and heat was zoned. I swear I’m going to have the sense to put that master suite in the middle in my next house, so I can be toasty for a change...
We’re almost the same size, but they should really put in 4 thermostats, switchable by season.
The second tier thermo on the 4th floor, so the heat shuts off early and the AC stays on.
Downstairs, the thermo is in the playroom, so the opposite happens,
If they put in two extra thermostats, with a switch...it would be more efficient
You need some of those motorized duct deflectors to force more warm air to the colder rooms.
Or space heaters for the cold areas.
Do you actually use the basement much? Basement family rooms are just made for cheesy faux fireplace space heaters.
