Saltwater Church suddenly lost heat in their office building on a Friday. The dispatcher was knowledgeable, professional, and efficient. Caleb came out within about an hour of our call, diagnosed the problem, and got the system up and … More running. He gave us the option of replacing the part that had shorted out, or seeing if the system could work adequately without it. We asked him to locate the part and give us a quote. We got the quote just 2 days later. We are very impressed and will use Five Star again! -
I had an emergency situation with my water chiller this morning and I work in aerospace chemical processing. So our Water Chiller is a key instrument to our processes. Without it we would be dead in the water. I made a call at 5am and the … More customer service was OUTSTANDING! Service tech was promptly here and ready to go.
