T.F.
We live in West Allen/Far North Plano area. Plano ISD. 4000 sq ft.
Our water, sewer, trash, etc is around $80 a month on average. It is a lot more when we are watering heavily. Our highest bill last year when we were watering heavily was over $300. Our trash bill also includes an extra cart.
Gas is lower in the summer because we have electric air. Summer gas bills are around $30 and in winter with heating the highest was about $200.
Electric (we use Champion and are locked in on a 12 month price in summer is around $200 with last years highest never going over $400. We did a lot to get that number as far as extra insulation, etc.
Shop electric companies on www.powertochoose.? either org or com, I don't know. We recently switched from a great program with Reliant after being customers about 12 yrs because they no longer offer our program and the price was crazy.
Good luck.
