Ok. We have had record heat and drought for the last two months. Nothing in 35 years like this. I was scared that the electric bill would be sky high. We paid a little extra to ensure it was covered. The AC on some days ran 24 hours it seemed.
Just got it and it is 22% less!!! than last year. So we started investigating what is different. The thermostat was kept at the same constant 75 degrees as last year. We were home all month. If the house got a little warm, we used a fan.
Differences:
1. We replace the 12 year old refrigerator this year with a super efficient one.
2. Replaced the TV with an LED one that uses less electricity.
3. Replaced the whole house air cleaner.
If it is the refrigerator, it will have paid for itself much faster than we thought (plus we love it.) Got an LG without ice maker and with a bottom freezer.
