"RefresH2O Water Systems is a great water purification and water softener system for the whole house. Scott was very informative about the system and Farley was very professional with the installation. We noticed the soft water immediately in the shower. We chose the reverse osmosis to the refrigerator, instead of the sink. We were very happy with that. Thank you Scott and Farley."

"Installed both a water softener and reverse osmosis system at my home. They did a great job with the installation, was professional, and ensured everything was working perfectly. Highly recommend their services for water purification needs!â"

"We owned a 17 yr old water softener that was no longer working. Rantz offered 2 options, he could fix the old unit or install a new one offering the additional benefit of a full water purifying system. He was excellent to work with at a great price so we chose new. We are so glad we did. Nate did the installation very professionally, went over the instructions on use & cleaned up. Rantz & Nate are so nice & wonderful to work with. We highly recommend!!!!"

"Professional and timely. Very impressed. Fixed our water heater at a reasonable cost. George was personable and I trusted his judgement. Great job!"

"The technician came on time and, although it took him longer than expected to install the system, he installed it and demonstrated the system for me. The next day, I noticed there was still water on the concrete close to the system but, I figured it was residual water. Apparently the system was leaking. Two days after install I contacted Leaf and advised them that the system was leaking. Early, the next business day, they arrived and repaired the leak and made sure I was happy. My system seems to be working well and I am satisfied."

"Fast and effective service. John was kind and friendly. Iam not sure about the general market price pressure reducing volve and water heater expansion tank replacement however they seem to be reasonable compared to other contractors and helped us on the same day. Good work John appreciate your patience"
