"I set up appointments to evaluate our water with5 providers. All told me I needed there treatment devices several told me I needed 5 or 6 devices. Tim Edwards said lets test the water and see what you have. We had salt water intrusion and needed a new well. Professional friendly service."

"Choice was fast, efficient, and kept me posted on the progress of the claim. Although the water leak issue was discovered on a Friday, they had a plumber there to investigate by Saturday morning. When it was determined that the 20+ year old heater needed to be replaced, the replacement ordered, on-site, and installed by Wednesday morning. I am glad that we opted for the Choice Ultimate plan as other than the initial $65 service fee, all but one $50 ancillary expense was covered."
