"My heat pump which had been installed 2 years ago by FH Furr suddenly stopped working Sunday afternoon. With the heat warnings in effect, I knew I needed help, FAST! Blair arrived this morning abd diagnosed the issue and replaced the condensation pump. These new "smart" systems have more brains than some humans!! When the pump failed, it shut down the entire system. However, Blair had the old school know-how and work ethic to get my system back online and back to normal. I have seen a nice change in technicians in the last 2 years and am always pleased to have them come out and fix any issues I may have. Keep up the good work!!"

"I was nervous to check on water systems for our house and am happy I found Purfect Water Solutions. After checking through Angie's list I got an immediate response and scheduled a time to meet with Scott. He came in and tested the water, he educated us on where our water quality is now (not great) and even tested our bottled water we got from the store (which was also not great). Great financing program if you worried about $ and referral program. W/ what we pay for water this was a no brainer. John came by our house in days with the system and had it hooked up the same morning. He was very nice, punctual, respectful and knowledgeable with what he is doing. I don't usually write reviews... but we want safe water for our kids and family and Scott & John did such a great job I want to write a good review and share our experience. Water is so important everyday. Do yourself a favor and at least get your water tested so you know what your family is drinking/washing with."

"After leaving a message on Angie's List on Saturday, Jim Stephens responded within an hour or so. After exchanging information, he volunteered to make a service call the next day Sunday. Because of my 5-day work week, this was a big relief. On Sunday, he called, as agreed, and asked if he could be at my house in a few minutes. As agreed, he arrived promptly. He diagnosed the problems and, at my request, provided details for solution fix. He had the part in his van and explained how the fix would be done and how it would work. He answered questions and explained clearly and thoroughly. Before beginning the work, he gave me an estimate, which I agreed to. After the work, his stated charge was no more than what his estimate had been. In addition to providing a high-quality solution, he provided, at my request, education about a related issue - the exterior drain for the sump pump. He thoroughly explained how the exterior drain could be extended away from the house to mitigate the fact that the water flow was eroding the soil near the foundation. When Jim left, I was a completely happy customer. I knew that 1) it was not necessary to replace the sump pump and 2) I had the knowledge, going forward, to know how to routinely check and maintain the sump pump functionality. Without hesitation, I can honestly say I will be calling JM Stephens for all my plumbing issues in the future."

"Naturally, on the hottest weekend of the summer in 2019, with a houseful of guests for that weekend, the capacitor went. Normally, I'd order the part and fix it myself, but that would have taken days to acquire. Air Temp showed up first thing in the morning the following day, and quickly verified the broken part and replaced it. Sure, of course it was more than doing it myself--but that's not the point. They were timely, had the part in hand, and were extremely reasonable on the price. We use them for our annual AC and heater checkups as well and will continue to do so for the foreseeable future. I highly recommend the team."
