We are the dedicated Carnes Crossroads division of Coastal Carolina’s wider Summerville HVAC Repair team.
Carnes Crossroads homes are built for efficiency, but AC systems still fail. We diagnose compressor, refrigerant, and airflow issues fast.
High-efficiency heat pumps are standard in Carnes Crossroads. We repair variable-speed systems, inverter boards, and refrigerant leaks.
Smart thermostats, zoning systems, and modern controls can malfunction. We troubleshoot and repair all system types.
Carnes Crossroads is one of Summerville’s most innovative communities—designed with sustainability, walkability, and energy efficiency in mind. The homes here often feature high-efficiency HVAC systems, smart thermostats, and advanced zoning controls that require specialized knowledge to repair.
Whether you’re in The Village dealing with an AC that’s not dehumidifying properly, or in The Cottages with a heat pump that won’t switch from cooling to heating—you need a technician who understands modern, efficient systems.
Coastal Carolina Comfort dispatches directly from Lipman St. in Summerville. We’re trained on the high-efficiency Trane, Carrier, Daikin, and Lennox systems commonly installed in Carnes Crossroads’ newer construction. That means accurate diagnostics and repairs that maintain your system’s efficiency ratings.
We also provide HVAC repair in Nexton, Cane Bay, The Ponds, and throughout Summerville.
High-efficiency systems use advanced electronics that can fail. We diagnose and replace inverter boards and control modules.
Even efficient systems lose cooling power with low refrigerant. We locate leaks, repair them, and recharge to manufacturer specs.
Zoned systems and tight home construction can create airflow issues. We balance systems for even comfort throughout your home.
Variable-speed systems shouldn't cycle frequently. If yours does, there's a problem with sensors, refrigerant, or controls.
Compressor replacement, refrigerant recharge, inverter repairs, and condenser cleaning for Carnes Crossroads' efficient homes.
Variable-speed compressor issues, defrost board failures, and reversing valve repairs—we service all high-efficiency heat pump brands.
ECM blower motor replacement, evaporator coil repairs, and zoning damper issues common in modern construction.
Same-day emergency service for Carnes Crossroads. When your system fails, call (843) 708-8735 for rapid response.
Zoned systems should provide consistent comfort. Hot or cold spots indicate damper, ductwork, or sensor problems.
If your energy bills are rising despite having a high-efficiency system, something is forcing it to work harder than designed.
Modern systems should control humidity precisely. If your home feels muggy or too dry, your system needs attention.
Variable-speed systems run quietly. Grinding, buzzing, or clicking sounds indicate mechanical or electrical problems.
Most HVAC repairs in Carnes Crossroads range from $150 to $500 for common issues like capacitor replacement, thermostat repair, or refrigerant recharge. High-efficiency systems with inverter boards or variable-speed components may cost more for parts. We provide upfront flat-rate pricing before any work begins—no surprises.
Absolutely. Carnes Crossroads homes often have advanced HVAC systems with variable-speed compressors, ECM motors, and smart controls. Our technicians are trained on Trane, Carrier, Daikin, and Lennox high-efficiency equipment and carry the diagnostic tools needed to service them properly.
