We are the dedicated Knightsville division of Coastal Carolina’s wider Summerville HVAC Repair team.
Knightsville summers are brutal. Whether you have a newer system or an older unit, we diagnose and repair AC problems same-day.
From heat pumps to gas furnaces, Knightsville has a mix of heating systems. We repair all types and brands.
Electrical failures, thermostat issues, and capacitor problems are common. We carry parts for all major brands on every truck.
Knightsville sits at the historic heart of Summerville, where charming older homes blend with newer construction. This mix means a wide variety of HVAC systems—from original units in mid-century homes to modern high-efficiency systems in recent builds. You need a technician who can handle them all.
Whether you’re near Old Trolley Road with an aging AC that’s lost its cool, or off Orangeburg Road with a heat pump that won’t switch modes—Coastal Carolina Comfort has the experience to diagnose and fix it fast.
We dispatch directly from Lipman St. in Summerville, not Charleston. We know Knightsville’s housing stock and the HVAC systems that come with it. From legacy Carrier and Trane units to newer Daikin and Lennox installations, we’ve seen it all and fixed it all.
We also provide HVAC repair in Sangaree, Wescott Plantation, and throughout Summerville.
Capacitors, contactors, and wiring degrade over time—especially in Knightsville's older homes with aging electrical systems.
Low refrigerant causes weak cooling and poor efficiency. We find leaks, repair them, and recharge your system properly.
Older Knightsville homes often have original ductwork with leaks, gaps, or inadequate insulation reducing efficiency.
Outdated thermostats or wiring issues cause erratic system behavior. We repair and upgrade thermostats for all system types.

Ignitor replacement, heat exchanger inspection, reversing valve repairs, and blower motor service for all heating system types.

Hot upstairs, cold downstairs? Older Knightsville homes often have ductwork or zoning issues causing uneven comfort.

Banging, squealing, grinding, or rattling sounds mean mechanical problems that worsen if ignored.
