What Clients Say
We started renting last month, paying $40/month. They don't have an online portal, but offer auto-pay. Initial install was pricey ($900) because of how our house was set up. You may or may not end up with a big install bill. The install takes a good 6-8 hours. Happy with the equipment, install, and service. Big shout out to our sales rep, Jason, who was patient with all my questions. He was friendly, professional, efficient, responsive, and respectful about wearing a mask while in our home. One piece of feedback is sales reps should wear proper masks (surgical or cloth, or double masking since CDC guidance has changed), instead of the pull-up neck covering things (not sure what they are called). Those have been proven to be less effective that a regular mask. A few weeks after the install, Jason followed up with a phone call to make sure we we had everything we needed. If you're considering a water softener, it is 100% worth it. We immediately noticed a big difference with showering and laundry. 10/10, highly recommend!
