Need help, this is crazy
So two weeks ago we finally had our fuses upgraded to breakers. The electrician came in the house and asked, "Do your lights blink? Do you have high power bills?". I answered yes to both, in fact, our power bills are 3 times higher than our friends with the same size houses and even larger houses. So he shows me the drop from the power company - about a foot long and all black and burny looking. He replaced it and our consumption has gone from 89kw a day to 39kw a day. Is this from the breakers or that undersized drop?
Unfortunately I didn't keep the old drop, but if I had, would I have a leg to stand on to make the power company pay us back for 15 years of $500. - $650. a month power bills for a 1650 sf house? I really just always thought it was because I kept the air on 72.
Thank you for your responses.
