See What Our Customers Are Saying!
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!!
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.

The Best install Job I ever seen. They answered all of our questions and some we didn't think of. Davis Heating is Really just the Best all aroun. Thank you so much. 9-23-2025
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.
