This gentleman was a pleasure to have at my home and I look forward to working with him in the future with any of my plumbing problems thank you Davis Heating and Air and plumbing for sending such a wonderful professional individual to my home. Ryder W thank you for everything that you did you where a God sent individual and so kind.
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.
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!!
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.
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.
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.
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 Exactly Is a Whole-Home Standby Generator?

You’ve probably seen those smaller, portable generators people use for camping or tailgating. A whole-home standby generator is a different beast entirely. Think of it as a permanent appliance, like your outdoor AC unit. It sits on a concrete pad outside your house and connects directly to your home’s electric panel.

When we say whole home, we mean it. It powers the whole show — your lights, your refrigerator, your heating and cooling system, and your outlets. It’s designed to automatically provide continuous energy to your entire house, not just a few selected circuits.

The Real Perks of Uninterrupted Backup Power

Having power during an outage protects your home and your family. Think about your sump pump in the basement; without power during a heavy rainstorm, you could be looking at serious water damage to your home and plumbing system. And what about the hundreds of dollars of food in your fridge and freezer? A prolonged outage can spoil it all. A standby generator also keeps your home security system online, your medical devices running, and your HVAC system humming along.

Powering Your Peace of Mind

Your standby generator’s engine needs a reliable fuel source to do its job. The two most common options are natural gas and liquid propane. If your home already has a natural gas line, we can often connect the generator directly to it. This provides a virtually endless supply of fuel.

For homes without natural gas access, a large propane tank is a fantastic alternative. We help you figure out the best size to get you through even an extended outage.

Special Offers & Financing Available

Everyone deserves access to dependable home comfort solutions, no matter the budget. We offer flexible financing options with approved credit, so you can get the services you need today without delay. Need a new generator before winter or summer storms hit? We make it possible with easy applications, low monthly payments, and a financing experience that puts your comfort first.

Why Professional Installation Is the Only Way to Go for Your Generator

Installing a whole-home generator involves complex, high-voltage electric work and, in many cases, connecting to your home’s plumbing for the fuel line. A proper, safe installation helps the system work as it should. Davis’ generator crew handles everything from the site preparation and proper placement to the final connections at your electrical panel. We set everything up perfectly for years of reliable backup service.

Keeping Your Generator Ready to Roll with Proper Maintenance

You wouldn’t drive your car for years without an oil change and expect it to run perfectly. Your generator is no different. It’s a powerful piece of machinery with an engine that needs periodic care. Our maintenance checks include running a self-test, checking the battery, inspecting fuel lines, changing the oil and filters, and making sure the entire system is in top-notch condition for the next power outage here in Virginia.
