"This happened on Sunday. Response was excellent and technician was knowledgeable and very helpful and thorough. His name was Austin. Price I can’t really judge—since I wanted it fixed (replace water heater) immediately I didn’t shop around."

"They replaced the main sewer line to the house from the septic tank and installed a riser so they could locate the main cover to the septic tank. They are very good and very fair priced."

"Manuel was wonderful! He analyzed the problem and gave me options. He came on Saturday morning to install the new water heater and couldn't have been nicer or more efficient. The ARS secretaries could take a lesson. They somehow got my phone # and house # wrong! It made for some confusions. Luckily I called them when the serviceman didn't come or call on time. We straightened out the phone # and Manuel had to call me to find the house. Tiny errors make a big difference. Overall, the experience was fine because the service man was so kind and helpful. I will try them again, but check and recheck the details."

"It went extremely well. The technician was professional and thorough. He spend at least 30 minutes with me reviewing the current configuration to ensure that the replacement water heater would meet our needs. We switched from a tank water heater to a tankless water heater and couldn't be happier. The tech did a great job with the installation and left the area clean and organized."

"They were prompt, left the house clean where they worked, and had it completed in a short period of time.  They explained everything very clearly about the care and operation of the unit, and were friendly and polite.  I would highly recommend them to anyone looking to install any type of water purification or water softener in their home.  They are clearly the experts and not just trying to sell you the most expensive thing they have to offer.  They will also make sure you get the right size water softener for the number of people in your home and the amount of water you generally use."

"I had called Andrew previous to the installation because I wanted to know about the new water heater; how well it was insulated, would it heat  cycle  less often than my 30+ year old heater, thus saving gas and would the pilot be easier to light than the old one, which required literally getting down on the cold, basement floor to light it.  All my concerns were answered  with professionalism and respect.
Andy was a very professional person/plumber/installer. He and I had a pleasant conversation throughout the installation process as I learned more about the process and my new water heater.  We even talked about soldering copper pipes, something I learned about doing many years ago, but which there was no need to do thanks to modern plumbing connections.  Watching Andy, who is a strong young man, haul the old water heater up the 9 steps to my garage and out to the truck where he would carry it away for disposal, made me even more thankful I/we had decided to replace it, it must have weighted close to three hundred pounds!
Andy was very professional and cleaned up any and all mess left after the installation, including wiping up spilled water from the pipes off of the new water heater, The install was estimated to take two hours but from arrival to departure took slightly over 90 minutes.  Very efficient.
