We had an excellent experience. It’s clear that management has instilled a real sense of ownership and accountability in their employees.

Facing an incoming snowstorm on a Saturday, we had an urgent furnace issue. Wendy answered the call and immediately took charge—she sourced the needed products and coordinated with the team to make sure our furnace was working that very day.

Her actions were a testament to her dedication, her strong relationships with the team, and the leadership culture at the company.

Erica Brown

Amazing experience using Davis today! Matthew came out after I had a concern with my thermostat! He checked it and also checked everything else for me as well! Gave me great advice on some things for the future, and answered every single question I had for him (which was a lot haha!) I was given multiple options on how I wanted to proceed with any issues he found. He was very honest and the prices they have are BEYOND fair! Each price I was given included the labor and service call fee and was still very fair! Overall this company turned a stressful time into a stress free time and put my anxiety at ease! Will DEFINITELY recommend to everyone!

We had our sewer line in our basement backed up and tried calling a few different companies to come out and fix it. Being that it was on a Sunday nobody wanted to come out. We ended up getting a hold of Davis who sent out James. He was very knowledgeable and explained everything that he was going to do. He did an amazing job and by the end of the night we were good to go. When James was done he also brought some towels and spray and cleaned up the mess that he made from the job he did. The next day Davis sent over a gentleman by the name of Dakota who ran a camera through our sewer lines. He was there to see why our sewer backed up. He was very professional and very knowledgeable on the job he was there to do. Between James and Dakota it was determined that because of where my house sits at the bottom of two Hills. When it rains we get all the rain water backing up the sewer lines. We ended up needing a check valve installed which meant that a crew needed to come over to our house and cut the concrete in my basement and dig out the stone to get to the sewer line so they could install this check valve. Victor and Hunter showed up and did an amazing job. They were very professional and tried to keep everything clean for us by putting plastic up. Another gentleman by the name of Will came over to give Victor and Hunter help on the job. Between the three of them they were able to get the job done and get it done fast. They brought in a vacuum and vacuum the floor, then they swept the floor, and then they swiffered the basement floor to try to get it as clean as possible. They also wipe down the Walls around the area they were in. From start to finish Davis did an amazing job. If there is any Plumbing work that you need done I would definitely give them a call.

Damien and Jacob installed a new hot water heater and water softener system. They did a GREAT GREAT JOB!! They explained what they were doing in a very understandable way. I really enjoyed talking to them. They were very professional and a pleasure to deal with. Thanks!!

Andrew

Philip arrived right on time(actually a bit earlier)from when he was scheduled. He was very pleasant and polite explaining every step of what he was doing. Instead of an expensive, full blown change out we agreed on an upgrade to satisfy my needs. We discussed if I wanted to make more changes what the next steps and costs would be. I was VERY satisfied with the Service Tech, his work and future suggestions.

Jennifer Porter

Everyone from the sales team to the install crew did a top notch job. Our boiler went out unexpectedly over Christmas, and Mike bent over backwards to help us get warmed up quickly and affordably. The crew showed up promptly, were very polite, and left no evidence of their visit aside from the new boiler- no mess, no damage. Very appreciative of the Davis crew for a job well done.

Tom LeNeave

We greatly appreciate Michael and Jacob doing the plumbing project in our home. We couldn't be more pleased with their very professional work. From the first day to the last day, they were very courtious, took the time to check-in with us, and made our house available each evening before they left so we could take showers and use the bathrooms. They worked quite hard the whole time and kept the project progressing well. The are men of integrity and we felt very comfortable and assured their work behind walls, under counters, and in the ceiling were top quality. We would easily go back to Davis for future projects because of them. We would highly recommend them and Davis Plumbing to anyone needing plumbing work. Thank you Michael and Jacob for a job well done.

Ryder spent over five hours at my elderly parents’ home resolving a sewer backup. My mom is very high-energy and outspoken, and my husband and son stepped in to help navigate the situation while I kept my dad occupied at my house.

Ryder handled everything with extraordinary patience, professionalism, and respect, especially considering all the chaos and personalities involved.

He never rushed, never complained, and delivered truly quality service for my parents. We are so grateful for his help and would absolutely recommend him.

Maribeth Schermer

Ryan did an outstanding job. He was pleasant and professional. Ryan took the time to explain the problem and how to fix it. His work was amazing and efficient. We will be using Davis again for our future HVAC needs. Thank you for your wonderful work.

What Is a Tankless Water Heater?

A tankless water heater, often referred to as an on-demand or instantaneous water heater, provides hot water only as it is needed. Unlike traditional systems that store and continuously heat water in a tank, tankless units use heating elements to warm water directly on its way to your taps. This method offers a dual benefit: it eliminates the need for a bulky tank and reduces energy consumption by avoiding the need to constantly reheat stored water.

The technology behind tankless water heaters has evolved significantly, allowing for more compact designs and improved efficiency. These advancements make tankless systems ideal for homes in Roanoke, accommodating various household sizes and water usage patterns without the spatial and operational constraints of tank-based models.

Would a tankless water heater be the perfect solution for your household? Schedule a water heater service today for a consultation, and one of our plumbers will be happy to help you!

Benefits of Tankless Models

Tankless water heaters offer several compelling benefits over their traditional counterparts. First and foremost, they are energy efficient. By heating water on demand, these units can reduce energy consumption by up to 30%, translating to noticeable savings on your utility bills. Additionally, their compact size frees up space within your home, providing flexibility in where they can be installed — from small closets to under sinks.

Tankless models also provide a continuous supply of hot water, perfect for families and individuals who need ample hot water for bathing, cooking, and other household activities. You can say goodbye to the frustration of running out of hot water during showers or while running appliances, a common issue with tank-based systems.

Longevity and Reliability

One of the most common questions from homeowners considering tankless water heaters is about their durability and lifespan. Tankless water heater systems typically last longer than traditional tank models. With proper water heater maintenance, a tankless unit can function efficiently for up to 20 years, nearly double the life expectancy of a traditional water heater. This longevity is largely due to the absence of a tank that can corrode over time and the fewer mechanical parts that are required to maintain constant temperatures.

What to Expect During the Installation Process

When you decide to install a tankless water heater, it’s important to understand the process. Installation typically involves a home inspection to determine the best location and type of unit, upgrading your home’s electrical system or gas lines if necessary, and installing the new unit with proper ventilation (for gas heaters).

We make sure that your new system is set up correctly, all connections are secure, and the unit is fully operational before we leave your property. We also provide a full rundown on how to operate your new heater to get the most out of its performance and features.
