Home Generator Services in Roanoke & Southside VA

The wind howls, the rain lashes down, and the lights flicker once… twice… then darkness. In that moment, you’ll wish you had a reliable generator instead of your phone’s flashlight.

A backup generator isn’t something you can run out and grab when the power lines go down. You want it waiting in the wings, ready to act the moment issues pop up. For many homeowners, that means working with the pros to find the right generator. Davis has incredible generator systems for our amazing clients here in Roanoke and across Southside VA.

See What Our Customers Are Saying!
Joshua was an incredible technician. Timely and incredibly knowledgeable. He was thorough, patient and answered all our questions regarding how our new thermostat works, the overall heating system and even checked an additional item associated with the unit under our house. He gave us a mini heat/cooling lesson that really helped us to understand how the system works, what had happened in our case and how to prepare for the coming cold months when we are here and traveling. Highly recommend Davis Heating/Cooling. And ask for Joshua if you can request a technician!!
James W was friendly and courteous. His assistant was very good. Everything is working great. I look at my new water lines and feel relaxed because there should be no more problems when the water is shutdown by the city. Every faucet/fixture has it's own cut off valve.
Davis Heating,Cooling,Plumbing is the Best service for AC around. They installed a moovair system that Heats down to 4 degrees WITHOUT Turning on those expensive Heat Strips. WOW this has to be one of the most efficient systems ever. The Crew AJ, Hunter & Trent were all Very Professional and Polite. They installed a compete New System in a day.

Matthew took the time to pinpoint the problem and to find a solution. Very professional technician. Follow up with Dakota to evaluate our options for our 30+ year old system was scheduled quickly and was very professional. A walk through was performed that detailed all the installation processes. Material availability was noted at the time as being a potential issue. Another project required a change to the work order and required an additional site vist. All this was handled by Dakota as well as creative solutions to material availability. Installation was well organized and the team was able to quickly pivot on a small filter issue. The four installation technicians, Cameron, Conner, Daniel, and Hunter were all courteous, professional, and respectful. The support team at Davis were quick to deliver supplies as modifications required. Everyone one on the install team worked together to get the job done. We could not be happier with the work and the professionals that are the Davis team.
I was very pleased with my first plumbing service with Davis Heating, Cooling, Plumbing, and Electric. James did a thorough investigation of my issue, explained the problems and my options, was able to answer all my questions, and get the problem fixed on the same day. He even tolerated my thieving dog being curious about the field of plumbing… I look forward to working with him on future plumbing needs.
TC and Josh were very professional and did a great job! Highly recommend Davis Heating, Cooling, Plumbing, and Electric. Gives me such piece of mind knowing that my home is safe and running efficiently. Thank you!

Travis J. also did a fantastic job! Y'all have an amazing team working for you!
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!!

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.
