For about a year now I have been wanting to get a smart temperature control for my central heating and air conditioner. The digital temperature control I had for all these years was superb and all, but I wanted something more. Something that would assist in maybe saving me some energy use to lower the electric bills that I end up consistently having in the summer time months of the year. I was just lazy in getting this smart temperature control going and in site! My fiance kept on me about it and then it would eventually slip my mind and I would not do it. I finally got around to it and made it happen! This was about 2 months ago. And let me tell you that the central heating and a/c method of mine is running much more efficient. That is first off. Second off, I already noticed a sizable difference in my electric bill on its first month. The fact that the smart temperature control can be programmed to go on and off mixed with me myself having control over turning it on and off when I am away from the house is what is causing the energy savings, and rather than having to run the central heating and a/c method while I am at work and my fiance is at work, I can now have it off the whole day and schedule it to turn back on about 30 hours before my fiance gets lake house from work. She is lake house a little earlier than me. So this actually works out well.
