Beaufort SC's Trusted HVAC Company

Beaufort is the seat of Beaufort County and the heart of the northern Lowcountry, spread across Port Royal Island and the sea islands between the Beaufort River and Port Royal Sound. It's a town of contrasts for an HVAC company: a National Historic Landmark downtown full of antebellum homes, established neighborhoods in Mossy Oaks and Pigeon Point, growing communities on Lady's Island and St. Helena, and a large military footprint tied to MCAS Beaufort and nearby Parris Island. Each of those brings different heating and cooling work — from squeezing modern comfort into a 150-year-old house to keeping newer subdivisions running through a brutal summer.

Coastline Heating & Air serves Beaufort from our base in Richmond Hill, GA — roughly an hour up I-95 and US-170. We're licensed and insured to perform HVAC work in South Carolina as well as Georgia, and we already run the Lowcountry every day for Bluffton, Hilton Head, and Hardeeville service. Beaufort is the natural next stop north. Our trucks carry common parts for the major brands installed throughout the area, so most repairs wrap up in a single visit.

Beaufort's heating mix leans heavily on heat pumps. The mild Lowcountry winter makes a heat pump a better fit here than a gas furnace in most homes, and a large share of what we service runs heat-pump equipment. Common heat pump repairs include reversing valve replacement, defrost control boards, auxiliary heat strips, and refrigerant charge correction. For homes on gas or propane — propane is common on the sea islands where there's no natural gas line — furnace repair covers ignitors, flame sensors, gas valves, inducer motors, and heat exchanger inspection. We handle both fuel types, and no-heat calls are dispatched 24/7 in the winter.

Pricing is transparent and flat-rate. Diagnostic visits start at $89 and roll into the repair total when you book same-day. Typical AC repair in Beaufort runs $150–$450 for minor work (capacitor, contactor, thermostat), $450–$1,200 for mid-range work (refrigerant leak find and recharge, blower motor, control board), and $1,200–$3,500 for major work (compressor or coil replacement). Full system replacement runs $7,500–$16,500 installed with several efficiency options. Ductless mini-split installs — a favorite for Beaufort's older downtown homes, sunrooms, and additions without existing ductwork — typically run $4,500–$7,500 for a single-zone system.

For ongoing care, the Coastline Comfort Club is the right answer for most Beaufort homeowners. The coastal combination of humidity, salt air, and pollen wears equipment harder than inland climates, so bi-annual maintenance pays off here. For $24/month you get two annual visits, a 21-point inspection each time, priority dispatch, no after-hours emergency fees, and 10% off every repair. Over a typical year that's less than two one-off tune-ups would cost, with a lot more coverage built in.
