112 HVAC Maintenance Contractors in Charleston, SC

Charleston's climate demands constant attention from cooling systems. Summer temperatures push toward 89 F with humidity hovering around 78%, driving heat indices well past what thermometers display, while mild winters averaging 43 F create almost no heating demand at all. The coastal humidity and salt air accelerate wear on outdoor units, making proactive service essential rather than optional. With 116 licensed contractors serving the Charleston metro and the area averaging a 3.8 rating across more than 23,000 consumer reviews, HVAC maintenance in Charleston remains a year-round industry priority.

Costs reflect the technical demands of maintaining systems in a corrosive coastal environment. A single AC tune-up ranges from $70 to $200, while a furnace tune-up runs $80 to $220, and a full HVAC inspection typically costs between $150 and $400. In South Carolina, contractors must hold a Mechanical Contractor Group 2 HVAC license from the state Contractor's Licensing Board, ensuring baseline competency for handling refrigerant and complex ductwork. These credentials matter when diagnosing latent cooling loads and moisture management issues unique to Lowcountry summers.
