M&B Heating and Air

At M&B Heating and Air, we help homeowners and businesses in the Charleston, South Carolina, area stay comfortable throughout the year. From air conditioning and heating repairs to system replacements, installations, and routine maintenance, we provide solutions tailored to each customer’s space, comfort needs, and budget. Our services also include geothermal HVAC. Our everyday pricing is fair and competitive, and we continually look for ways to help reduce the cost of repairs and new equipment. We also offer after-hours service based on the urgency of the situation and technician availability, with additional charges applying for after-hours and holiday visits.

We believe excellent HVAC service begins with knowledgeable, dependable people. Our technicians receive ongoing training and certification, are factory-trained, and are qualified to work on all brands of air conditioning, heating, indoor air quality, and refrigeration equipment. We employ NATE-certified technicians who arrive promptly, diagnose problems carefully, and complete work efficiently and professionally. Whether we are handling an emergency repair, performing a seasonal tune-up, or installing a new system, we focus on quality workmanship and attentive service. Regular inspections, cleaning, and maintenance can help systems operate efficiently, identify developing problems, and reduce the risk of unexpected breakdowns.

We treat every home with care and respect. Our employees undergo background checks before they are hired, and our installation technicians participate in random drug testing. We use floor savers, protective clothing, and vacuums to help keep homes clean, and we stand behind our work with written satisfaction, workmanship, and cleanliness guarantees. If qualifying equipment that we installed proves to be a lemon within one year, our No Lemon Guarantee provides for its replacement at no cost. Cool Club Planned Service members also receive priority service. Above all, we remain committed to honesty, accessibility, exceptional customer care, and building long-term relationships. From scheduling and payment discussions to follow-up after a service visit, we work to make every interaction as convenient as possible and earn the confidence of the people we serve.
