“Mr Shelton spent almost the entire day (Saturday at that) fixing our hot water heater. Clear explanations and demonstrations of what was wrong and how to fix it. He was careful with our stuff and a good communicator! Also clear instructions on follow up after he leaves. One hour has the top tier of the top quality technicians in Sierra vista and Michael Shelton is up there with the best!”

He always takes time and answers any and all questions for us. If we are unsure on something he takes the time to check or walk us through anything. Always top notch and great customer service from this young man. Keep up the great customer service from all of you, from phone calls, to follow up calls. 100% great service.”
