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."

"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

Installing weather stripping or upgrading to insulated panels can improve efficiency.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

The effect a gas fireplace has on your gas bill will depend on how often you use it, the size of the rooms you’re heating with it, and the BTUs of the fireplace itself, but generally speaking, it should only cost a few cents an hour to run it when it’s on. It will consume minimal energy when it’s “off” if you have a pilot light running constantly, but some modern gas fireplaces don’t require a constant pilot light.

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
