"Very grateful for such an easy and pleasant experience when I suddenly found my very old hot water heater leaking all over the basement floor on a Sunday evening. I did a quick panicked search and thankfully Arctic answered my call and put me at ease with a quote for a replacement and an install appt for first call the next morning. Adam K arrived on time, was very sweet & professional, and installed our new unit in under an hour. Will definitely use Arctic again!"

"Service Tech Ed DeMore, who had originally installed our tankless water heater, responded and realised the unit had to be reset and recalibrated after an error message caused the unit to stop and not restart during the snowstorm of last Monday. He had us up and running in just a short amount of time. Eddie is an excellent and knowledgable employee with a great attitude. He is very pleasant and we hope A. J. Perry realises what a great asset they have in Ed."

"The plumber answered my initial call and I was able to describe the problem we were having with the guest room shower fixture that only produced very hot water. I sent him a photo of the fixture. He came the next morning and replaced the cartridge, unclogged the drain in the tub, and fixed the stopper that was not closing properly. All of his services were priced reasonably!"

"I wish I could hire someone of Roger's calibre, brilliance and ethical principals on all projects I need to accomplish around our home. It is a pleasure to have Roger for a service call or job as he willingly shares his wealth of knowledge to assist you in understanding all aspects of your home systems. He takes his time and explains each and every detail in an easy to understand way . Not only is he straightforward, honest, highly efficient and extremely knowledgeable but if you need to call him he will guide you through all issues and concerns and explain the steps you need to go through to do such things as change your filter if you wish to do this yourself. I would definitely highly recommend Purely Water with Roger Garrett. I believe he will work with you to achieve whatever you are trying to accomplish."
