My fiance and I have this continuing discussion at certain times of the year….basically Springtime and fall. I am warmer natured than she is and I love the apartment cool….she does not, however her perfect temperature to have the Air Conditioner and Heater plan set at is about 73 degrees, mine is 75 degrees. There are times our cooling system should be finally working when she has the furnace set and running. I have even had to split down and run a fan facing my side of the bed at certain times to keep some cooler air blowing while she runs the Heater and Air Conditioner component on warm, fortunately, every one of us have a newer Heating and AC component in our apartment so our electric bills are not real high-priced even with the varying temperatures. It can be quite frustrating at times when I am doing housework yet she wants the temperature set at 73 degrees. It is simple to split into a sweat when doing housework. Finally, I found the answer and I contacted the local Heating and A/C company to inquire about the programmable temperature control. After talking to a specialist I discovered that was the exact thing every one of us needed! By having this type of temperature control I am able to set the rooms to varying temperature so our bedroom, where she spends a lot of time, can be set on 73 degrees and the family room, where I spend most of my time, can be set on 75 degrees. The two of us are both excited now with the temperature of our home. Finally peace in our apartment regarding the comfort of both of us.
