"I had a water softener and filtration system installed in my home. It's fabulous! Austin was very reliable and friendly. He was extremely efficient. I'm so happy with my system, and with Jones Air and Water."

"David called to let me know he was on his way. After evaluating the situation, he discussed my options and showed me the pricing for each. After clearing the blockage, he showed me what he found. Since this is an old house with old pipes, he also had me check the basement room near the window well for any water - just in case. (Fortunately it was dry). I appreciated that he wore a mask and disinfected the tablet before handing it to me to sign. Overall a very positive experience."

"We all know water softener salesmen are unique. Everett was knowledgeable and easy to work with. We feel like we received a great value for the money and appreciated the follow up after the job was completed. I 100% would do business again with the Jones family."

"John has always been about the most polite and professional contractor we have used, and has been our go-to guy for several years now. From installing a water softener to fixing old piping to/from the upstairs bath to installing a toilet (which I couldn't do since I've never sweated copper piping, which this required). Prices are fair, and the jobs are not done until he's sure they are. Will definitely continue using his services. Highly recommended."
