"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."

"The project was completed seamlessly and Jim and his helpers were competent, hard-working and didn't mind explaining what was going on every step of the way! His years of experience are evident, and make him a great diagnostician and problem-solver. He even went out to buy stone to line the bottom of the trench dug outside of the house to insure that the new pipe would be stabilized underneath! There were a number of things that could have been complications (like tree roots, and breaks in the pipes going to the septic tank), but it was clear to me that Jim would be able to address them, if they did surface. This was the kind of thing that makes a homeowner very nervous, so I was so relieved that I had Jim do this work. Experienced, competent, honorable, and a really nice guy! So glad that I won't have to conduct searches for a plumber in the future!"
