“
Our condominium association has enjoyed StarTex for about three years now and they are definitely super. We locked in a rate and really enjoyed turning the thermostat up or down without tears when we got their bill. Super service/customer support. ”

great choice
(4.9 / 5)
“
On moving to Texas, we were confronted by choosing an electric company. This was overwhelming. I did research on Texas companies, and read a lot of material. I chose StarTexPower, and have never looked back. The rate I pay is such a savings over my previous experience in another state. There have been no problems with this company. I like the way they do business, and will remain a loyal customer. ”

The Benefits of Choice
(4.9 / 5)
“
The benefits of choice are clear when you work with StarTex Power. I didn't realize how good I had it until I moved away. But from start to finish, and at every point in between, StarTex went above and beyond to deliver competitive prices and excellent customer service. I was most impressed when a VP picked up to answer a billing question. You just don't find that service elsewhere. I miss having the option to choose a power company. But if I ever make it back to Texas, StarTex is the choice for me! ”

Honest and dependable company
(4.9 / 5)
“
First company I switched to who was honest with their rate. They didn't add any unexpected charges like the other 2 companies I used. I will stay with them forever unless they do the same thing to me in the future but I don't expect that to happen. Also, it's great to do business with a company here in Texas. ”

Hot Water Heater a
(4.8 / 5)
“
My hot water heater was leaking and 21 yrs old. Mary Ellen was very helpful with financial info. Kyle Baxley and Jared Dotson came the same day and in no time a new unit was professionally installed with no mess and the old unit was removed. They were careful to cover their shoes and cleaned up anything they used. I sincerely appreciate the efforts of all involved to get my new hot water heater installed the same day I called. ”

So far, things are great. The only things I found mildly annoying were: 1) The letter they sent advertised a lower rate, but "my area" was not eligible. 2) The website is not easy to navigate. Otherwise, I'm quite happy. ”
