B W Heating & Air

Upgraded from a 30+ year old unit and would have expected to see energy savings. Well it's hard to see energy savings when there is open duct junctions under your house. After calling them back out to find correct problems for over three months, they have given up trying to find the answer. I'm now having power bills $40-$50 a month higher than with my previous unit. They don't seem to have any clue where to even look.
