I would like to know..why is it the ac guys problem everytime someone adds to their house and they receive a high electric bill.
Can we place the blame on the framer,the insulation guy,or
even the home owner themself who now has more lights and tv to leave on thruout the house.
1800 new + what existing 1500 from before..I too would say the 350 dollar bill not bad.
