"Bobby responded quickly and made it out to fix my dryer in a more than reasonable amount of time. Not only was the pricing extremely fair but the service was better. Highly recommend. Will be using them in the future."

"They demonstrated excellence in understanding the need, responsiveness, communicating every action to be taken ahead of time, calculating a fair estimate, explaining options for replacement, timeliness, and exceeding all expectations. Our technician, Zach Womer was outstanding in diagnosing the issues with my water heater, recommending replacements by listing the strengths and limitations of each choice, explaining the installation, confirming the availability of the replacement, estimating installation timing accurately, completing the job thoroughly and neatly, and most of all always staying in touch including after the services were provided. Poseidon and Zach are outstanding and deserving of customers' confidence."

"We are in a very rural area and finding providers on Angies list is difficult here. We had some plumbing problems about 2 years ago and called a popular plumbing company, they are prevalent in this area. They "fixed" a list of items. One of the items was a broken spigot outside. A year later we had to call them back to fix the same spigot. They did a cheap patch up job instead of doing the job right. They charged us again for something they should've done right the first time. Now, less than a year later we had the same problem and we figured we'd take our chances with somebody else. I think we found precision plumbing in the phone book but we were very lucky this time. Jeff Matthews was very prompt, called and kept us informed of when he would be coming and also kept us informed of the cost for everything before he began the work. He explained what needed to be done which was more involved than a broken spigot and said it is something that other plumbers will often do a quick patch job on. He was very well prepared and had all the parts needed on his truck. While he was under the house doing the repairs he noticed that our dryer vent had come off and he re-attached it. I should also mention that it was over 100 degrees that day. He was very professional and I will recommend him to anyone."

"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!!"

"This is why I really like working with Jim. First of all, he took a late evening phone call from me, when I was really just expecting to get voicemail. Prior to scheduling, he actually suggested a way to see if I can fix the disposal on my own and walked me through what to do over the phone. Unfortunately, whatever was stuck in there (looked like a metal object), was really stuck and would not budge. Jim came the next day and installed a new garbage disposal for a very fair price."

"Hague was very quick to respond, give estimate and do installation of our hot water heater. They even suggested that I contact previous water heater company for possible warranty and it was covered !"
