Owned and Operated Proudly by: Walter Flynn I have been in business since 2001. We are a full service HVAC company. We install, maintenance and repair all makes, models and manufacturers of Heating and Air equipment. We also give FREE second opinions on repair work! Should you have an issue while your system is under manufacturer warranty - no problem. It does not matter who installed the equipment we can service the parts warranty - residential or commercial. We also can take care of all your Commercial HVAC, refrigeration and cooking equipment needs including manufacturer warranties no matter the installer. We specialize in all restaurant and convenience store equipment. Beverage, ice machines, coolers, freezers, fryers, warming boxes, holding cabinets, filter systems, lighting, small appliances, on site stainless steel and steel welding and fabrication. We are fully insured and licensed. Thank you for your consideration !

"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."

Contact our experience executive manager Sara Murphy([email protected]) to learn more.

"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."

Energy Efficiency Auditing questions, answered by experts

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.
