I had requested quotes from several places but Glenn, the owner of Mountain Fresh, was the only one that gave me a straightforward quote for the work I requested. No harassing phone calls or rude messages like other places trying to upsell products. The technician, Corey, was so professional and patiently answered my questions as he completed the work. He even found a corroded connection to the drain that he cleaned and replaced on the spot. And at the end of all of it, I was charged exactly what Glenn originally quoted. Excellent, smooth process from start to finish. I’ll be using Mountain Fresh from now on!

Mtn Fresh does water treatment systems in home - RO systems, Water softeners, tankless water heater, water pressure valves - the works. I have had them take care of both my AZ homes - this is about 20 years now. They are friendly, polite, professional, reasonably priced. They are also quite knowledgeable. They service my water softener, my RO unit and my tankless water heater, and I go to no one else.

Plummer put a hose bib on the soft water system! Now I can wash my Coach & Cars with soft water, they didnâ t tell me they would install that! But the Plummer took the initiative to install it himself. A very pleasant surprise!
