"Installation was GREAT!!!! Slyvester answered all my questions and was very professional and friendly. A/C working great. There was a mix up with payment up front, which costed about 35 minutes, but it was resolved and customer service said they would resolve this for future customers. If you plan to use multiple payment methods, my recommendation would be to have a backup plan or call the front office to arrange things before installation."

"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."
