Very pleased with the people. From the office to the technician that came out, a most pleasant experience. Everyone goes through every detail and nothing is overlooked. I’m a long time customer and these professionals earned my trust years ago. They go well beyond what is expected and know their business. In these times when most strive for “Good Enough “ The Davis team goes for “Excellence”. I highly recommend Davis and will continue to be a loyal customer.
Hello from NC - long and simple...from the young ladies running the day to day operations to Eric the AC technician, a new customer from out of state has been born. My AC unit went down and I knew from the prior owner "Davis Heating" was the installation team he used, so I called them for help. It all moved so smoothly I was a little shocked. I was informed multiple times as to Eric's ETA - that system works like a champ! Then Eric got himself into the condo to quickly assess the issue. 3 minutes of his time and a quick phone call and I was back in business. That my friends is an A+++ for customer service, honesty, integrity and just good old fashion business! Thanks for making me feel like a "VIP" - K Spencer
Great experience overall. From Matthew coming out to inspect my system and giving me options, to Dakota coming out a couple days later to give me price quotes/options, to the guys coming over to install a new system. AJ, Hunter and Trent did a fantastic job, explaining things to me and answering all of my questions. Did a great cleanup job too. I will definitely call Davis Heating and Cooling anytime I need help in the future. Thank you for the wonderful service!!
We are sooo pleased with the work done by James! He is personable and professional. Even my dogs like him. He replaced a toilet for us and did a great job! That may sound simple but, he had to make several adjustments. My toilet is now level, sturdy, aesthetic and clean! He cleaned up after himself and carried away all of the garbage. This is not the first time James has done work for us. He has worked on our hot water heater and water system. It was good to see him this time also. Great work! Davis Heating, AC and Plumbing (Electrical also), have never disappointed us and always have been accessible. James is a great asset to the company! It was a bonus to hear of his and his wife’s support for our community’s pet shelter. Well done James!!
I used Davis plumbing to work in my bathroom to repair the toilet.
James was the technician that did the repairs. This young man was absolutely great ! James took time to explain all the work he was doing explain everything he could or would not do in order to make things better for his customer (me) and I have no doubt that he treats all customers with the same courtesy that he showed me.
If I need other work/ repairs done I will definitely call Davis Plumbing, Electric, Heating/Air Conditioning and I will request that James be the tech that works at my house.
I will be recommending Davis, and James to those that want excellent customer service.

Thank you James for doing an EXCELLENT JOB and for having such Wonderful Customer service Skills.

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).

Our technicians tackle every aspect of installation with professionalism and attention to detail. 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.
