Whole-House Generators in Roanoke, VA

Don’t Put Your Safety on Standby

It’s amazing where electricity has taken us. You can turn on every light in your home with just a flick of the finger. But all it takes is a quick flick of the lights for the power to go out completely.

Power outages affect your comfort, safety and peace of mind. Between spoiled perishables and power surges, a lot can happen when the lights go out. But with a whole-house generator from Davis, you can keep the power in your hands.

Chuck Fuller

We received amazing service from the Team at Davis! The service manager Jonathon was quick to respond to our issue and got us into their schedule in just a couple days. The installers Daniel and Joseph worked quickly and quietly, and left our space cleaner than they found it. Very happy with the experience.

Victor B

I am happy to have selected Davis for my heating, plumbing, and air conditioning at Smith Mountain Lake. So far, Davis has done three jobs for me, and I am satisfied with the results and pricing. In particular, Daniel and Isaac did a great job installing a new HVAC for me. They are hardworking, knowledgeable, and very efficient as a team. Again, I am glad to have access to Davis in my area and would select them again with 100% confidence. Update: More great work from Davis. Michael solved a difficult plumbing issue by re-routing the outdated pipes in my old lake cottage, a complicated job that saved me from having to re-plomb the whole house. Again, 100% happy and confident with Davis' experts!

Keith Johnson

After calling for HVAC service (for no A/C) for our recently acquired 25 year old system, we received a quick response from Davis. Our first tech Chris came out, trouble shot the no A/C issue, and repaired the improperly wired thermostat right away. He gave us an estimate on the needs of the current system that he saw but suggested a consultation for a complete review as it was a lot to invest in an older system. A few days later, Mike came out and offered multiple options to update our two systems, including financing opportunities (I need to emphasize there was never any pressure offering "today only" pricing, been through that before!). We were fortunate, the systems we chose to upgrade with, Davis had in stock (one dual fuel & one heat pump) and within a week crews were available to install.
Fast forward 5 days; the original plan was for a two day install, one for each floor. The day before day one install, Davis staff called and asked if they could do both units in one day? Worked for us! The install crew(s) that arrived were on time as scheduled, all were very polite, each one made sure they introduced themselves, and they focused on their work and finished all the work within their scheduled 8 hours. I cannot praise them enough, no mess or any debris left behind, they even vacuumed the carpet in the bedroom where the attic access is.
We are happy with Davis services and are pleased to recommend them to others!

Sam and devin were awesome! Explained in detail and advised the best options. Even came back the same day to do minor adjustment as my preference! Would recommend to anyone.

Jeffrey White

Damian, Devan, and Michael replaced our 10-year-old water heater with a new Navien tankless unit and installed a Water Right Impression Plus water softener. Our hard water was taking a toll on our faucets and appliances, so they installed a new kitchen faucet and a fridge water line at no charge for labor. Highly professional and detail oriented. They were also very clear in explaining the new equipment and regular maintenance. It’s great to contract with such skilled and personable plumbers.

How Does a Standby Generator Work?

Standby generators are like the guard that never sleeps. As soon as the utility lines fail, your generator will turn on within seconds and take over. You’ll be able to use your appliances as normal and preserve perishables such as food and medicine.

Once utility power is restored, your generator will return to standby mode. The beauty of whole-house generators is that you don’t need to do anything other than maintain them. Your generator will automatically detect when to step in versus when to stand down.

Why Invest in One?

If your area loses power frequently, then you’re already familiar with the frustrations of power outages. Standby generators are beneficial because they will:

Prevent perishables from spoiling
Preserve medicines that need to be refrigerated
Allow you to continue using your appliances without interruption
Help prevent power surges
Keep everyone safe and comfortable through the storm
Prevent your pipes from freezing during the winter (which can lead to burst pipes and flooding).

Keep the Power Going With Davis

Power outages don’t show any respect for your schedule or your safety. With a dependable standby generator, you can forget about what’s happening outside and power through the day—no matter what.
