"We needed to have an ole iron pipe replaced as well as galvanized lines replaced. A leak was found at the base of a toilet, and this was repaired. The interior of the toilet was also replaced. The job was well done, and the workman pleasant to work with. I thought they were a bit expensive, but I have not have this kind of work done in awhile. It took a couple of tries for the office to get my address and email correct for estimates to be sent, however. .. not the plumber’s fault."

"Excellent!!! The plumber was informative and so quick. He went over what he would need to do and how much it would cost. The person that took my appointment was also very courteous. They said between 8-10am and he was there at around 8:30am a lot sooner then expected. I really appreciate that as a single female he didn't ask personal questions, if I was married or what my husband, boyfriend or father could do to help me like other service people have from other companies."

"AC Tech Aaron was highly knowledgeable, amicable and was able to solve an issue that previously caused ARS to replace a newly installed HVC system with another new system, however, Aaron was the one to solve the ongoing issue I had with both current and previous systems. The issue was, the AC simply was not efficient enough to cool my house, reason, the air filters were severely clogged. Solution: Aaron applied a commercial degreaser, then washed both filters, this dissolved an accumulation of over 10 years worth of gunk and soot like dirt. Thanks to Aaron, my AC now is finally running to its full capacity without compromising its efficiency or causing it to overheat or worse, break down. I would recommend ARS to at a minimum inspect and equally clean all AC filters as that would go a long way towards resulting in a far better AC/HVC performance with better efficiency. Thank you Aaron. Joseph"

"10 year old system, so worried about big expense. Mike of Plumbing Innovators pulled off a messy valve, installed a new one, and provided a spare for me to use if/when it clogged again. Mike took the time to explain life span of some well water components. Higher these folks with a high degree of confidence in their honesty & integrity. I have used them exclusively for the past five years."

"Outstanding response to failed water heater on Sunday afternoon. While water was now heating, noted a leak in the heater which would result in a future failure. I chose to replace the water heater. Mr. Thurston had the same item in stock. Delivered new and replaced the old heater in less than two hours total."
