My fiance plus I have this continuing discussion at certain times of the year….basically Springtime plus fall. I am warmer natured than she is plus I care about the beach house cool….she does not! Her perfect temperature to have the Air Conditioner plus Heater idea set at is about 68 degrees, mine is 70 degrees. There are times our undefined should be legitimately working when she has the gas furnace set plus running. I have even had to break down plus run a fan facing my side of the bed at certain times to keep some cooler air blowing while she runs the Heater plus Air Conditioner unit on warm! Fortunately, the two of us have a newer Heating in addition to Air Conditioning unit in our home so our electric bills are not real extravagant even with the varying temperatures. It can be quite frustrating at times when I am doing housework yet she wants the temperature set at 68 degrees. It is straightforward to break into a sweat when doing housework. Finally, I found the answer plus I contacted the local Heating in addition to Air Conditioning supplier to inquire about the programmable temperature control. After talking to a worker I discovered that was the exact thing the two of us needed! By having this type of temperature control I am able to set the rooms to varying temperature so our family room, where she spends a lot of time, can be set on 68 degrees plus the living room, where I spend most of my time, can be set on 70 degrees. We are both cheerful now with the temperature of our home. Finally peace in our home regarding the comfort of both of us.
