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...
There’s always a space heater, I keep one in the Princess’ room, because she’s over the garage.
