I’m well aware of the recommended setting for one’s air conditioner in the summer. They say that 78 degrees will keep your home relatively cool while saving a good bit on energy bills. I simply cannot accept such a high temperature! My thermostat has never been set above 75 degrees in the summer. In the evenings when I sleep, it’s set to 69 degrees. I know people who are energy efficient penny pinchers would ask why on Earth would I lower the temperature on my thermostat at night when it gets cooler outside. To them, I would simply reply that doctors recommend that your bedroom be between 60 and 69 degrees at night in order to get the best quality sleep. So, I stick to the upper threshold, and I must admit that I’m far more comfortable and able to sleep much better than if I had left the thermostat on 75 degrees, much less 78! I pay the energy bill, so nobody needs to tell me how much I should be willing to spend for my own personal comfort. All of this being said, in the winter, I am more than happy to set the recommended temperature on my thermostat to save money. They say 68 degrees allows your home to be sufficiently warm enough while saving money during a cold winter. That sounds great to me. The only problem is, the winters around here are relatively mild. My HVAC unit would be working much harder to maintain 68 degrees during the winter than it would be to maintain 75!
