Dear Hank,

We just wanted to let you know how happy we have been with our water softener and our Reverse Osmosis system that we bought from you. We have had them now for 17 years and have never had a problem with them. They are still working as well as the day they were installed. We are very happy that we chose BioTech and would recommend your product to anyone.

Purchased whole house softener and RO for kitchen. Everything was done professionally and on time and for less that competition charges. Hank is good man to deal with and we couldn’t be happier. Maybe I will sell him my Harley 🙂

First, I’d like to begin by stating that I knew nada about water softeners before I knew I needed one. In fact, I only decided to look into water softeners because the Sweetwater company, which had a sales concession at Home Depot, was giving away e-cards for free water testing. Well, after the water testing, I felt like I was on an episode of “Fear Factor” – I couldn’t believe I allowed hard water into my home. So began my journey to buy a water softener, which would be precluded by many interviews with many companies. They all sounded great….and eerily similar. However, there was something different about the owner of BioTech. I thought he was arrogant at first, when he asked me to interview him after all the others so I could “save the best for last.” Such a boastful comment meant I’d be a little tougher on this guy than I was with the other companies. I now have a complete home refinement unit that I definitely believe in and I feel great about. Selecting BioTech is looking to be the best decision I’ve made since purchasing my home. Thanks, Hank!

After considering several vendors of water softeners and reverse osmosis water conditioners we selected Hank and BioTech. Quality of product, warranty, cost and foremost, integrity of the owner made our decision easy. Promptness, professionalism, technical knowledge, long history and tidiness of the installers, made us comfortable that we had made the BEST choice. Buy BioTech, you can t get better!

We were very pleased with our experience. The owner is the one who comes to your home and he doesn’t try to do a hard sell. He just explains what he has to offer and can make comparisons with other systems out there. His technicians were very courteous and did the install during the “Stay at Home” and worked extra hard to invade our home as little as possible. We were appreciative. They even sprayed disinfectant to help aid with any risk. They left no mess which we appreciated.

I got quotes from 4 companies and went with Biotech. I am very impressed with the product, the professionalism, knowledge of the owner, and the long history. The installers were prompt and very neat. Everything was carefully explained and all my questions were answered. It was a great experience and I look forward to having this same company do the annual service. Highly Recommend them!
