My technician was Jason Barnard! He was absolutely fantastic! He showed up on time straight to the point, friendly, and very knowledgeable about plumbing. He had the new water heater installed the very same day! Would recommend to anybody who needs any plumbing and heating/ A/C work done! Thank you so much!

My experience with Pioneer has been fantastic! One of our properties ran into an electrical issue where we needed an electrician. I called Pioneer and they had someone available right away. The person who handled the phone call was extremely professional and was very prompt. They also send out a text when your electrician is on the way with their picture. I thought this was a fabulous touch for safety reasons! Pioneer sent out our electrician, Lynn Collins who was AMAZING! He communicated extremely well, gave an estimate of when he got to our property, and promptly called us when the job was complete. It was such an easy process with Pioneer and I will be using them in the future for all our electrical needs. Thank you Pioneer and Lynn!

Nancy Livergood

James Mize from Pioneer came on time this morning to perform the routine maintenance on my HVAC unit. James was here on time and was courteous, professional and very knowledgeable. He worked efficiently to inspect and clean the unit. The capacitor on the outdoor unit was reading low and he recommended replacing before summer usage. He had the part on his truck and was able to change it without having to make a return service call. He answered all my questions and didn't mind my curiosity. I was very satisfied with the service call and will continue to use Pioneer Heat and Air for future service/maintenance needs.

My hot water tank was nearing the end of its life so I decided to replace it with a new one and add a circulating pump with Pioneer. Aidan and Cody arrived this morning and had it all set and ready to go by the afternoon. They checked and rechecked to assure everything was ready to go and in working order. To say they went above and beyond would be an understatement. Both were friendly and courteous and are surely a great asset to have working for this company. This is the second time I’ve had work done by Pioneer and honestly, couldn’t be happier! I highly recommend!

We were very pleased with the quality of materials and service for the job performed. We had a hot mess of plumbing under our kitchen sink that needed to be reconstructed/redesigned. Our technician’s name was Jason. He was very professional and a pleasure to have conversation with. We would highly recommend Pioneer to our friends and family. ??????????
