Ryder spent over five hours at my elderly parents’ home resolving a sewer backup. My mom is very high-energy and outspoken, and my husband and son stepped in to help navigate the situation while I kept my dad occupied at my house.

Ryder handled everything with extraordinary patience, professionalism, and respect, especially considering all the chaos and personalities involved.

He never rushed, never complained, and delivered truly quality service for my parents. We are so grateful for his help and would absolutely recommend him.
Daniel was a pleasure to work with and he worked hard to resolve our generator issue. He was very thorough and came back as promised to install the ordered part. Very happy with our service and will continue to use them in the future.
Two days before Thanksgiving I learned that I needed to replace my 20-year-old furnace...before the coldest holiday in recent history!! Davis repairmen arrived on the day before the holiday, and because of a defective factory part, worked until after 7pm to ensure that I had heat.
They returned after Thanksgiving, and even the next week to ensure that my thermostat was calibrated to the correct temperature.
Not only did I receive exceptional service from the installers, Travis and the service department manager stayed with the project until all was working properly.
Thank you, Davis!
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.

The Facts About Poor Indoor Air Quality

According to the Environmental Protection Agency, Americans spend 90 percent of their time indoors, where the concentration of pollutants is often two to five times higher than outdoors. While the structures of residences and businesses are great for temperature control, they aren’t so great for indoor air quality. The more we seal ourselves off from the outdoors, the more we expose ourselves to these contaminants that cause poor air quality.

When the air in your home is polluted, it can lead to a number of symptoms, including:

  • Dizziness
  • Headaches
  • Nasal congestion
  • Fatigue
  • Itchy throat
  • Watery eyes
  • Sneezing
  • Coughing
  • Allergy and asthma flare-ups

In addition to reducing symptoms, proper IAQ will help improve the performance and longevity of your HVAC equipment, including your heating and air conditioning systems. By removing debris in your air, you’ll prevent your equipment from overworking itself and costing you more in energy bills.

Davis Is Your Leading Indoor Air Quality Specialist

Just because your home is a breeding ground for pollutants, this doesn’t mean you can’t eliminate them, improve air quality, and have fresh air. With the proper strategy, you can catch contaminants in their tracks and remove them. And it all starts with an air quality test from our IAQ specialists.

Using advanced technology, we’ll identify a number of indoor air contaminants that could be affecting your air, including:

  • Allergens (pet dander, dust, pollen, etc.)
  • Mold
  • Secondhand smoke fumes
  • Volatile organic compounds (VOCs)
  • Radon
  • Carbon monoxide
  • Asbestos
  • Pesticides
  • And more!

Improving Indoor Air Quality: A Look at Common Solutions

Once we determine what indoor air pollutants are impacting your air, we can recommend the proper treatment. We carry and install a number of air-quality products!

Air Purifiers and Air Filtration Systems

These work by trapping airborne particles like dust, allergens, pet dander, and smoke using air filters. HEPA filters are particularly effective at capturing very small particles. By removing these irritants from circulation, air purifiers and filtration systems can significantly improve indoor air quality.

UV Lights

Installed within your HVAC system’s ductwork, UV lights emit ultraviolet radiation that neutralizes bacteria, viruses, and mold spores as they circulate through the air stream. This helps to reduce the spread of germs and allergens within your home.

Whole-Home Ventilation Systems

These systems address a different aspect of air quality — ventilation. They work by continuously bringing in fresh outdoor air and removing stale indoor air that can trap pollutants. This exchange of air helps dilute and remove indoor air contaminants, improving overall air quality.

Humidifiers

Dry air can irritate respiratory passages and worsen allergies. Humidifiers add moisture to the air, creating a more comfortable and healthier environment, especially during dry winter months. However, it’s important to maintain proper humidity levels to avoid mold growth.

Dehumidifiers

In contrast, humid climates can lead to mold growth and exacerbate dust mite problems. Dehumidifiers remove excess moisture from the air, improving air quality in humid environments and creating a less hospitable environment for mold and dust mites.

It’s important to tailor the product to the problem. That’s why we take the time to discuss what you’re experiencing, perform an air quality test, and then determine the proper strategy. 

Indoor Air Quality Maintenance Services

Once your equipment has been installed, it’s important to maintain it each year. As part of our Home Guard Maintenance Agreement, we will inspect your air quality equipment — along with your heater, air conditioner, and generator — at one affordable price. It’s the best way to ensure your equipment is doing its job and making your air safe to breathe through every season.
