"Commercial & Residential Heating & Air LLC, Moncks Corner is an exceptional organization with highly qualified technicians. A family member needed a new HVAC unit, and Walter and his team exceeded our expectations. We explained the importance of having central heat and air as soon as humanly possible but needed an unconventional approach. We needed a change agent. We were requesting consideration because we could not afford the total costs associated with the traditional methods of purchasing a new system. Exhausted, and thinking outside of the box, to help meet the need for heating a home during this winter season, we thought of purchasing a unit. We qualified to buy a unit but did not follow through until we could find that one person — just one who would take a risk and help a family in need. Angie’s List was our absolute go-to. We stepped out on faith, believing that we would find someone with a heart of compassion, understanding that this was a complete liability. Without hesitation, Walter accepted the task at hand, he was indeed our change, writing an estimate the same day and in record-breaking time. He simultaneously worked to help identify the unit and appropriate specifications so that we would not make an inaccurate purchase. He orchestrated the entire project from start to finish, keeping a constant line of communication. Walter knew when the unit arrived, dates that he would be available for installation, and timely follow-ups. On the day of service, we received a call; it was Walter, and the crew was en route. We were encouraged it was surreal, it took the unit one week to reach Charleston, and installed day two after the delivery. Once installed, would you believe that we received an additional military discount? Commercial & Residential Heating & Air LLC, basically installed this unit at cost. We are in complete disbelief and know that greater things are in store for Walter and his team. Thank you for helping our family. We are so blessed to have found you and appreciate all that you have done."

"If I could leave zero stars, I would. My solar system has never been up and running properly, and SC Solar has done nothing to help. After paying over $65,000 for a system that is now essentially worthless, I feel completely scammed. All the company needed to do was remove and reinstall the panels after I had my roof replaced. Instead, they left exposed wires, creating a major fire hazard. Their negligence has now led to severe roof leaks and damages that total over $100,000 ? and they still won?t come back to fix the mess they created. SC Solar claims to pride themselves on their work, but in reality, they are fraudulent, unresponsive, and completely unprofessional. I?ve been left with nothing but financial stress, safety concerns, and a broken system. Avoid this company at all costs."
