The electric company in that area is Arizona Public Service (APS). There is another electric company in the metro Phoenix area -- Salt River Project (SRP), but they don't service that area. Your gas company would be Southwest Gas. City water/sewer/trash collection. With regard to phone service, internet, cable, etc. you will have some choices. The two largest providers are Cox Communications and Qwest.
If you need contact info, let me know. In the meantime, if you'd like assistance with a property search or sample listings for the area, I'd be happy to help. I also have a Buyer's Rebate program which credits you back funds toward your closing costs. You can learn more at my website.
