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!
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.
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!!

Problems You Can Avoid With Furnace Maintenance

Skipping a maintenance appointment may seem like no big deal, but small issues inside a heating system don’t stay small for long. Routine care helps prevent problems that can shorten the lifespan of a furnace, raise energy bills, or even put your family at risk.

During a professional furnace maintenance service, technicians look for signs of wear, clean away buildup, and make adjustments that keep the system running at its best. Here are a few headaches homeowners can avoid with proper care:

  • Unexpected Breakdowns: Small parts like sensors, switches, or belts can wear down and cause the entire system to fail. A maintenance check catches these problems before they turn into an emergency call.
  • Carbon Monoxide Hazards: Cracks in the heat exchanger or issues with gas lines can create leaks. Maintenance includes careful inspection to keep your home safe from this invisible danger.
  • Poor Indoor Air Quality: Dust, dirt, and soot build up inside a furnace and ductwork. Cleaning these areas helps your air filter do its job and improves the air your family breathes.
  • Uneven Heating: Dirty burners or weak airflow leave some rooms cold while others stay warm. A tune-up balances the system and restores comfort.
  • High Energy Bills: A poorly maintained furnace has to work harder. Maintenance keeps it efficient and helps reduce wasted energy.

Furnace Tune Ups in Roanoke, VA

Even the best furnaces lose efficiency over time. Dust collects on burners, airflow gets restricted, and parts wear down. A professional furnace tune-up in Roanoke, VA, resets the system to run like new. Think of it as a checkup that saves money month after month by helping the furnace burn fuel cleanly and distribute heat evenly.

Our technicians check gas pressure, test airflow, clean critical parts, and calibrate the thermostat. These adjustments may sound insignificant, but they add up to a big improvement in efficiency. Homeowners often notice steadier temperatures and fewer cycles, which means less wear on the equipment and lower heating costs.

What to Expect During Furnace Maintenance

Homeowners often wonder what actually happens during a furnace visit. We keep the process clear and simple, so you always know what’s going on with your heating system.

Detailed System Inspection

The appointment begins with a full inspection of the furnace and connected systems. That means checking burners, wiring, the ignition system, and the heat exchanger. We also review ductwork for leaks and test for any signs of carbon monoxide hazards. This inspection lays out exactly how the system is performing and flags anything that needs attention before it turns into a bigger issue.

This stage is also where we spot early signs of trouble. If we find issues that call for furnace repair or even furnace replacement, we explain them clearly so you can make an informed choice.

Cleaning and Fine-Tuning

Next, the system gets a good cleaning. Dirt, soot, and debris inside the combustion chamber or on burners reduce efficiency and can create uneven heat. The air filter is checked and replaced if needed. Once the system is clean, our technician fine-tunes gas pressure, checks flame patterns, and calibrates the thermostat.

These small adjustments have a big impact. Cleaning and fine-tuning help restore airflow, balance fuel use, and reduce strain on the motor, which translates to lower bills and fewer breakdowns.

Testing and Review

With everything cleaned and adjusted, the system is fired up and tested under real conditions. The technician monitors airflow, temperature, and safety controls. They listen for unusual noises, test electrical components, and confirm that the furnace is running smoothly.

The appointment wraps up with a clear explanation of what was done and any issues that might need repair. You’ll leave knowing exactly where your system stands and confident that it’s ready for the season ahead.

Frequently Asked Questions

How often should I schedule furnace maintenance in Roanoke, VA?

Most homeowners benefit from scheduling furnace maintenance in Roanoke, VA, once a year, ideally in the fall before heavy use. Annual service helps catch problems early, cleans the system, and keeps the furnace working efficiently.

Can furnace maintenance prevent carbon monoxide leaks?

Yes. Maintenance checks the heat exchanger, flue, and combustion system for cracks or leaks that could release carbon monoxide. Technicians also test safety controls and verify that ventilation is working properly. Preventing these hazards is one of the most important reasons to schedule annual service.

How does furnace maintenance affect indoor air quality?

Dust, soot, and debris collect inside the heating system and ducts. During a furnace maintenance service, these areas are cleaned, and air filters are replaced. This reduces allergens, improves airflow, and helps the home feel fresher.

Does skipping furnace maintenance affect my warranty?

Yes. Many manufacturers require proof of regular furnace maintenance service to maintain your warranty. Skipping maintenance could void coverage, leaving you responsible for repair or replacement costs. Keeping records of inspections and tune-ups is a smart way to protect your investment.

Can Davis help with other services besides furnace maintenance?

Absolutely. Davis Heating, Cooling, Plumbing & Electric provides a full range of services, including heat pump installation. Our team also handles plumbing, air conditioning, and electrical needs, making us a one-stop shop for home comfort.
