See What Our Customers Are Saying!
My experience with Davis Heating,Cooling, Plumbing and Electric was as good as it gets. We had no water, major leak in our yard so we just googled Davis mainly because they advertised 24 hour service. Great decision that was. James was awesome, really knew exactly what to do and really polite. Really good operator as well. Will definitely use Davis in the future.
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.

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!!

Every Home Needs Working Smoke & CO Detectors

You only have about 3-4 minutes to escape a house fire. Without a functioning smoke detector, you might wake up already trapped by flames or overcome by smoke. The risk multiplies at night when your family sleeps.

Carbon monoxide is even more treacherous, as this invisible, odorless gas gives zero warning signs as it fills your home. A functioning carbon monoxide detector can alert you before CO levels become deadly. This can come from everyday appliances like your furnace, water heater, or gas stove when they malfunction. Many of your home’s electrical wiring and gas appliances pose hidden risks that these detectors can help mitigate before tragedy strikes.

How Our Smoke & CO Detector Services Keep You Protected

Our Roanoke and Southside VA electricians don’t just slap up any detector and call it a day. We take a close look at every home, identifying the optimal placement for complete coverage. Kitchens, bedrooms, hallways, and basements all need different approaches for maximum protection.

We install hardwired systems that connect throughout your home, giving you precious extra seconds during an emergency. Battery backup keeps them working even during power outages.

Beyond installation, we offer testing and maintenance to keep your fire safety system in peak condition. Smoke and carbon monoxide detectors have expiration dates, typically 7-10 years, depending on the model. We will check existing units and recommend replacements when needed.

Warning Signs You Need Smoke & CO Detector Service in Roanoke and Southside VA

Signs Your Smoke Detector Needs Attention:

  • Random chirping or beeping sounds
  • Yellow or discolored indicator light (should be green or red)
  • Detector is over 10 years old
  • False alarms when cooking or showering
  • No sound during monthly testing
  • Visible dust buildup on the exterior

Signs Your Carbon Monoxide Detector Requires Service:

  • End-of-life warning beeps (usually 5 beeps every minute)
  • The unit is over 7 years old
  • Digital display showing error codes
  • Detector fails the test button check
  • Corrosion on battery terminals
  • Intermittent alarms with no apparent cause

If you notice any of these warning signs, don’t gamble with your family’s safety. Our technicians can diagnose and fix these issues fast! Call ASAP!

Smart Detector Options for Modern Homes

Today’s smoke and carbon monoxide detectors do far more than just sound an alarm. There are smart detection systems that connect to your phone, sending alerts even when you’re away from home. These advanced units can tell you exactly which room has detected smoke or CO gas, helping you direct your family to safety during an emergency.

For homeowners with existing fire suppression systems, we can integrate new detectors with your sprinklers for a unique fire safety approach. Many Roanoke and Southside VA residents are even upgrading to combination smoke/CO detectors to simplify their home safety systems while improving protection. These dual-function units save space and reduce maintenance needs while providing crucial protection against both threats.

Strategic Placement to Maximize Your Protection

Where you put your detectors matters just as much as which type you choose. The National Fire Protection Association recommends smoke detectors in every bedroom, outside each sleeping area, and on every level of your home, including the basement.

Carbon monoxide detectors work best when placed on each floor and near potential CO sources like your furnace, water heater, or attached garage. A professional installation from Davis avoids common mistakes, giving your family the protection you deserve.

Serving Communities Throughout Southside VA

We proudly provide electrical services to homeowners across Danville, Salem, Smith Mountain Lake, and surrounding communities. Davis electricians can upgrade electrical panels to help you manage additional safety systems without overloading your home’s capacity and even offer electrical inspections that reduce the chances of your smoke detector needing to go off in the first place. By identifying and fixing wiring issues before they cause fires, we’re adding another layer of protection for your family.

Don’t Wait Until It’s Too Late

A malfunctioning smoke or carbon monoxide detector puts your entire family at risk every night. You can’t afford to gamble with these odds. Call Davis Heating, Cooling, Plumbing & Electric today for fast, professional detector installation or service that could save your life tomorrow.
