Noticing everyones body heat

Only a couple of years ago, I visited my older sister on the other side of the country.  I spent a month with her, and was totally comfortable in her guest kitchen. Although her beach home is not equipped with a central cooling system, there was a window a/c in my room.  Despite outdoor rapidly adjusting temperatures in the high eighties, the room was perfectly cool. I had a little remote control which allows me to make adjustments without even getting out of bed.  With a tap of my finger, I could raise or lower temperature, regulate fan speed and even target humidity levels. At the end of the a busy day, I was always eager to crawl into bed. I had no trouble sleeping and always felt rested in the day.  This past winter, I decided to visit my sister for another week. My stay was not as comfortable this time. Her home is outfitted with a forced air oil furnace with a single control unit. Because of only the only control unit, every room is heated to the same temperature.  The guest kitchen was always slightly overheated, and I’d wake up damp with sweat. Plus, without the a/c drowning out other sounds, I had a fantastic deal of trouble sleeping. I heard the wind chime outside my window, the oil furnace kicking on and off, and the cat barking.  I even heard my sister snoring in her kitchen on the other side of the wall. My sister definitely needs to upgrade her heating plan to zone control. The guest kitchen is usually empty, and yet she’s paying to heat it all Winter long.
