"Steve arrived when estimated and determined what needed to be done, left for a while and retuned with a very good water heater and drip pan and began the change out. He cleaned the area and hauled the old water heater away. The installation looked professional."

"I was very pleased with the entire project. We received a new water treatment & purification system and new water heater. Glen explained the whole procedure and the installers were very courteous and respectful. We are enjoying the peace of mind knowing that the job was done right and we have the best water."

"Josh arrived on time for our appointment. We mentioned we did not have hot water. He initially checked whether there was power to both the lower and upper thermostats on the hot water heater. Finding no power for both thermostats, he then checked the main power line to the water heater. Once again, there was no power. He checked the circuit board and found the circuit breaker had been inadvertently shut off. After turning the circuit breaker to the on position, he did hear the water heater beginning to heat water. He also gave us advice on servicing the water heater in the future along with possible additions of a water softener and a reverse osmosis unit to offset the hard water from our town water system. We would definitely recommend this company for future plumbing needs."

"Water heater broke on Sunday, made a bunch of calls around town to get it fixed, Ace was the only one that called back on Sunday and they came out early on Monday. They installed a tankless water heater and by 3 p.m. The best part was that they were be to offer to finance the job at a much lower interest rate (9%) compared to home depot (23%). Awesome customer service. 🖒🖒🖒🖒🖒"

"Chris knew what he was doing and explained. Tank's bladder was breeched internally. He showed me a valve on the tank that when initiated bled water instead of air. He indicated I needed a new tank, He will return to install. He clearly showed competence. He spoke well and listened well. I would recommend."

"Glenn is a great salesman. I very much appreciated how up front and honest he was about his products. It became clear to me very quickly that I wanted to consider going with them for my purchase. I asked Glenn the same questions repeatedly for a few days until I had understood everything I was uncertain about. He was more than patient and willing to help me. I ended up going with the higher end water conditioner unit. Install went relatively smoothly. My house was not pre plumbed for a water softener, so there was some extra work involved. His contractors were friendly. They didn't mind me watching the install as I was intrigued by the whole process. When they left they made sure to clean up any mess they had made. The install location was a big of a compromise from what I originally wanted, but I think it will work just fine. At the end of the day I couldn't get the other companies to give me quotes, come out to my home for a face to face, and the prices I did see from the competition was not anywhere near ballpark for Fresh Mountain in regards to quality and value. These guys know what they are doing, they stand behind their products confidently and are patient when you have questions. I'll be passing along the word to friends and family. Thanks again, Glenn!"

"La Darian was terrific. He came to inspect the plumbing and discovered that the house needed a water pressure reducing valve due to high pressure. In addition, the water heater was nearing its end of life. He was very knowledgeable, professional and personable. He worked within my time frame on consecutive days. He was on time, worked steady and completed the job in an efficient manner. He was easy to talk with and informed me each step of the way of the process. He presented me with choices when it came to purchasing my needed products. I want La Darian to work on any plumbing needs I may have in the future. He is a top notch professional."
