If you have several people in your home, get Heating & Air Conditioning zone control. Temperature control causes the most fighting in a household; Everybody has odd control component preferences, and it makes sense that their home office should be the temperature they want. I have a family of many & all of us each have our own indoor air handler & control unit… My husband & I agree on the heating & cooling in our home office. Whatever all of us set it to doesn’t affect anyone else. My youngsters have their own control component & my mother has her own room & control component device. It is nice since the community rooms can be a problem. Every one of us all sit down in the living room at night & watch a movie, and before zone control it was a huge deal what the control component was set to. My mother hates A/C pouring on her & my kid doesn’t want to be heated. My child doesn’t prefer the feeling of air blowing on her. I just want everyone to get along, and now that everyone has their own space & temperature control program to go to, the living room temperature is not a huge deal. Every one of us all are okay with it being 68 degrees. If that means heating or air conditioning, the group just deals with it; For the home office I mainly control that control unit. When I cook I prefer to turn on the AC. It keeps me from perspiring to death & fights the heat from the stove… After everyone is done with the mal, off goes the control unit, zone control is also wonderful for energy bills too, not just comfort.
