Emergency water leak under the house. on a Saturday eve and I called and Michael was on call and came. Right out . Gave an estimate and fixed the issue plus letting me know what else needs done . Appreciate him taking time away from family to come straight out an hour or so away. Thanks Michael Cantrell. Plus Ethan N. Also had to come out the same evening to check why the power went out in one room and half of another. He found the issues and replaced the problem and also let us know what else was wrong that we put on our 2026 to do list in January. Thanks so much. The electric was a hard one we were stumped 🤔 but he figured it out and fixed it. Thank you both for coming and staying late into the evening to ensure we now fixed both plumbing and electric issues until next time we will see you soon to upgrade our pipes and electrical work. When you have a home . It's best to up keep it that's what I told my husband. Thank u guy's you are appreciated. And once again same issue with the electric and Davis to the rescue. Thanks Ethan for coming back out and finding the issue and fixing it once again.

Michael from Davis is awesome! He's the real deal. Punctual, super friendly, very skilled, and really cares about doing the job right. He went above and beyond and made the whole process stress-free. I'll definitely ask for him for future plumbing jobs. Thanks Michael! Great job!

Audra Schroeder

Travis just left our home after working on our HVAC system. I've never had a technician be so thorough or thoughtful in explaining the process with updates or progress and outlining all options for dealing with our issue. We were experiencing overwhelming musty and moldy smells coming from our HVAC in our new house. I had another company come clean the system and they were done in 30 minutes and the smell didn't change. Travis listened to and understood my concerns about the smell and took them seriously. He disassembled our unit and THOROUGHLY cleaned the coils and the inside of our HVAC system and resolved issues that we didn't even know we had. Very appreciate of the attention to detail and the understanding. Appreciate you, Travis!

The water heater was off on a Saturday and after trying some things, it still wasn't working. I called Davis and was informed they consider a water heater issue as an emergency and would send over a technician (after hours fee applies). Ryder called when he was about 35 minutes away to notify me he was on the way. He arrived on time, covered his shoes and we talked about the issue and the Davis customer satisfaction process to keep me informed from the beginning. Ryder resolved the issue and got the water heater up and working due to his knowledge and expertise! Later in the afternoon the temperature / pressure valve failed unexpectedly and Ryder returned to investigate further and also determined the expansion tank was waterlogged. So, rather patching an old water heater, a new one would be the best route. Ryder stepped up and obtained the new one and installed it, which meant working late into the night. Ryder knew we needed the hot water so the family could get ready for a funeral visitation service on Sunday and he went above and beyond to ensure that the water heater would be ready. I would call Davis again if I had a need. Thanks to everyone at Davis!

On November 10, 2025 we requested a cost estimate from Davis Heating, Cooling, Plumbing and Electric to have an expansion tank installed on our hot water heater. On the 13th, Ryder W. from the Plumbing Department arrived early, fully prepared to provide a written estimate after consulting with us and looking at the hot water heater and its location.

During our discussions we learned Davis would also wall mount an expansion tank we provided (we preferred a brand not stocked by Davis). In addition to the expansion tank, we also requested an estimate to replace both outside spigots that were leaking. After examining both spigots, Ryder explained our replacement options, the installation methods used (PEX crimping verses soldering), time to complete the work, and loss of water service while the tank installation and spigot repairs were being done. He also suggested installing a gauged pressure-reducing valve (PRV) where the main water supply line enters the house. The gaged PRV provides a positive method to monitor and prevent high pressure from entering the house plumbing which can damage pipes, valves, and equipment. Ryder then prepared a written detailed cost estimate for each requested task and financing options for our review and discussion. We decided to be preventative instead of reactive, and have scheduled to have everything done in the coming weeks.

Ryder is a pleasant and polite young man who is punctual, competent, and customer oriented. He provided a detailed cost estimate for the tank installation that we had initially requested and effortlessly modified it to include the additional tasks we discussed after his arrival. All our questions were addressed and he did a thorough job explaining our options and the installation process. Ryder will be installing all the plumbing equipment himself. We look forward to his next visit.

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.

A. I.

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!!

When Should I Consider a Furnace Replacement?

When your furnace has shut down altogether and is beyond repair, it’s clear that you need to replace it. But what about when your system is still working, just not as good as it once did? This may warrant replacement, too.

Ask yourself these questions when it comes to your heater:

Is it not working like it used to? Furnaces can wear down with each and every use. After a number of years, they will lose the efficiency you once enjoyed, causing your heating bills to spike.
Is it providing adequate and reliable heat? You know your home comfort better than anyone else. If you’re constantly adjusting and readjusting the thermostat to no avail, it may be time to consider a new furnace installation that won’t play games with you.
Is it impacting your indoor air quality? Older units don’t filter out dust, debris, and other impurities as effectively, leading to a significant decline in your home’s air quality. Schedule an indoor air quality testing service if your heating system is a source of indoor air pollution.
Are you spending more on repairs than it’s worth? There comes a point when repairs will outweigh the cost of your current heating unit. Don’t shell out hundreds of dollars to repair an old, unreliable, and inefficient heater that could fail again next month or next year. Invest in a furnace installation that guarantees your family’s comfort for many years to come instead!
How old is the unit? Most furnaces have a lifespan ranging from 15 to 20 years. This is the best time to replace your unit without fear of being left in the cold.

It can cost a pretty penny to frequently contact a heating repair company. When you look at the big picture, you’ll save more in the long run by investing in a reliable, more efficient unit!

If your furnace is 15+ years old, it’s likely on its last legs. You might be better off replacing your unit ahead of time rather than running your furnace into the ground and losing heat at the worst possible time.

We’ll Help You Pick the Right System

Furnaces come in all shapes and sizes. In fact, all ducted and ductless heating systems do! The sheer number of options can be overwhelming to any homeowner or business owner. When you purchase your heater through our furnace or heat pump specialists, we’ll be your guide every step of the way.

Let’s discuss your long-term heating goals and the most crucial factors to consider, including:

How much square footage requires heating.
Your energy-saving goals.
Your schedule (i.e., how often you’re home, how heavily you’ll be relying on your furnace, etc.).
Your home’s layout and whether you stand to benefit from zoned heating.
… And more!

Once we install your new system, we’ll check to make sure your furnace is working just as it should be. We’ll inspect the ducts to check for leaks and measure airflow to ensure your system is ready to serve you best. Plus, we’ll give you all the gas furnace maintenance tips and tricks to ensure you’re capable of providing your new system with the best care possible!

What Our Furnace Installation Process Looks Like

A new furnace is a significant investment, so the process should be organized and transparent. We don’t leave you guessing about what’s happening next. Here’s a look at how our furnace installers in Roanoke, VA, handle the project step by step.

In-Home Consultation and System Sizing

We start by visiting your home, taking measurements, and learning about your family’s comfort needs. A furnace isn’t one-size-fits-all, and guessing at the size leads to wasted energy or a heating system that can’t keep up. We carefully calculate the load, check existing duct conditions, and talk about your goals for efficiency and comfort.

Installation Day Setup

On the scheduled day, our crew arrives with the equipment, tools, and protective gear to keep your home clean. Drop cloths, shoe covers, and a fully stocked truck are standard. The old furnace comes out, the new one goes in, and our technicians double-check connections for gas, electricity, and venting. The installation includes a safety inspection of the heat exchanger, thermostat wiring, and air filter setup.

Final Testing and Walkthrough

Once the system is in place, we fire it up and test the airflow, temperature accuracy, and system response. Finally, we explain the features, show you how to use the thermostat, and answer questions before leaving. We want you to feel confident running your new HVAC system.

Protect Your Furnace With Our Maintenance Agreement

A brand-new furnace deserves proper care if you want it to last. Regular maintenance catches small issues before they snowball into breakdowns and keeps the system running efficiently. Our Home Guard Maintenance Agreement is designed to make this simple for families who don’t want another thing on their to-do list.

With the plan, you can expect benefits such as:

Comprehensive Coverage: Bi-annual HVAC inspections plus annual plumbing and electrical inspections.
Priority Service: Faster scheduling for diagnostics and repairs so you’re not stuck waiting during a cold spell.
Cost Savings: Members-only discounts on indoor air quality products and other essential home services.
Extended Lifespan: Professional maintenance helps prevent another costly furnace replacement in Roanoke, VA, before its time.
Transferable Coverage: If you move within our service area, your plan moves with you.
