Here's a natural, detailed 5-star review you can use for a plumbing contractor who replaced a water heater and backflow valve: --- ⭐⭐⭐⭐⭐ Absolutely Outstanding Service – Highly Recommend! I recently needed to replace both my old water heater and the backflow valve on my property, and I’m so glad I chose Preferred Home Services. From the very first call, their team was professional, responsive, and honest about pricing and timelines. They arrived on time, explained everything clearly, and walked me through the options for the new water heater (including energy-efficient models). The installation was done cleanly and efficiently — no mess left behind, and they even took away the old unit for me. The backflow valve replacement was handled with the same level of care and expertise. They made sure everything was up to code and tested both the new water heater and the backflow preventer thoroughly before leaving. The difference in hot water recovery time and overall performance is night and day. My water pressure is better, and I finally have reliable hot water again without worrying about leaks or code violations. If you need reliable, trustworthy plumbing work — especially water heater or backflow valve replacement — look no further. Jacob and Michael are the real deal. I’ll definitely be calling them for any future plumbing needs. Thank you for the excellent work! — Stephen in Summerville SC

Sage is a Mastef Plumber who identified the problem I needed help with. What I really appreciated was that he was able to explain the problems to me and what he recommended to fix them. His knowledge of the plumbing system, parts & how the repairs could make the system more efficient & last longer convinced me that it was a good inestment. Sage was knowledgeable, wasted no time, and was respectful of my home and my time. The cost was a little more than I expected, but he fixed the problem,wasted no time, and I recommend Sage and Preferred Home Services.

Efficient, thorough, pleasant disposition. Great having him in the house.

Josh Hood was extremely professional and helpful when our AC unit needed repair. Highly recommend this company!

Griffin King is amazing, he came checked out our HVAC system to ensure it was working properly. Took the time to explain what he saw as far as how to fix our dust problem. He made recommendations to alleviate the dust. Griffin is professional, courteous, knowledgeable and friendly. He’s a keeper your company is fortunate to have Griffin as an employee. Kudos to Griffin King

I've been using Preferred Home services for several years and very satisfied with the services they perform. Every technician that has serviced my heat pump systems and tankless water heater has been nothing less than friendly and professional. I'm always notified in advance of their arrival. The technicians explain their findings, provide solutions, make me aware of issues that eventually will occur through normal usage and wearing out of the system components that eventually need replacement along what they found concerning the current condition of a part or system component and potentially how much longer it may remain functional. They document and track all service work records performed so that other technicians are aware of the history of prior service and maintenance work when they come to service my systems. My experiences with Preferred and all their staffing has been great. I'm glad I found Preferred Home Services and would certainly recommend them to anyone.

It was my annual maintenance check for my HVAC unit.

I found these wonderful people a short time ago and they recently installed a new hvac system in my house. It was finished in a day. Everyone from Preferred I’ve met so far is professional, efficient and knowledgeable. Awesome customer service. Thanks to everyone involved.

While dealing with a separate issue in my home, the hot water tank replacement was the last thing that I thought would be the easiest to handle. When Matt assured me same day replacement, I was shocked! Thank you so much!

Chris Clifton tech representative Preferred in a very professional way because of that

Griffin did a great job with the maintenance on my HVAC system. He was very friendly, on time, explained in detail everything that he did, and was clear with all additional information that the system could use. Very happy with this tech. Definitely recommend.

The best of the BEST! I couldn't recommend Preferred Home Services enough. The staff is friendly, fast, and courteous. Hailey kept us updated on our service throughout the day and had a technician to our home in record time. From the office staff to the field technicians, no one else compares!

Chris was very professional and quick to respond. He gave an appropriate amount of time to address the problem versus leaving too early. He did a solid plumbing/sewer line upgrade.
