"Requested a quote for converting our old hot water heater to a new tankless unit, Southern Plumbing sent Nick S. to us, hands down the most professional,, and meticulous repair job. Nick beat Michael and Sons’ estimate by $2000 for the same unit without even knowing it. Southern’s business office was responsive, honest, and fast. I Would highly recommend Southern Plumbing."

"Allen and Justin (Blacksburg location) did their work late on a Friday afternoon without any complaints. They were efficient and I felt like they were honest in their assessment and repair advice. They walked me through almost everything and gave advice on how to extend the water heater life."

"I had an issue with removing my clothes washer connections from the fixtures. I had to contact a plumber and I decided on Plumbing Innovators due to the excellent service I received from them in the past. Two technicians came (Parker and Matt L) and they removed the old washer lines, installed new ones, and tested things. They also were so kind as to provide me with water leak detector (for free) because they noticed that I had a VERY old water heater too (over 32 years old and still kicking). I was so surprised that I gave them both big hugs. They were so kind and delightful to talk to. I can't say enough about them. I hope I don't need them in the future but if I do I'll definitely call Plumbing Innovatgors."

"Outstanding response to failed water heater on Sunday afternoon. While water was now heating, noted a leak in the heater which would result in a future failure. I chose to replace the water heater. Mr. Thurston had the same item in stock. Delivered new and replaced the old heater in less than two hours total."

"I have used Ricky Merryman 4 times over the past three years to replace my hot water heater, air conditioner, blower and gas furnace. Every time he was very responsive, very honest in his appraisals and affordable. Him and his family are wonderful to work with and very professional. He is extremely trustworthy and I would HIGHLY recommend him for any of your heating and cooling needs.

"I have been using Advanced Environmental Solutions for over 18 years. Initially I had them take care of routine maintenance and repairs of my HVAC system. In 2018 I did over a $200,000 complete home renovation. I called upon AES to completely redo my single home HVAC to a 3-system installation. I also had them take care of upgrading my electrical panel and installing a new subpanel to support my new professional kitchen. Prior to doing the work, the team came to my house and did a complete survey of what would be required. Once done - John Davis came to my home and explained what they found, their recommendation and the best options and costs associated with my options. Once we get the right mix agreed upon, they set-up a schedule to do the work ensuring that we were not in anyway inconvenienced. We were thrilled with the work and professionalism of the team. My daughter decided to completely gut their home in 2018 and we called upon AES to take care of their home like ours. If you are looking for the finest in professionalism for HVAC and electrical work - and want to be treated like a member of the family and not an end point dollar - then I highly recommend AES. I have been recommending them forever and will continue to do so!!"
