Why Us
When summer heat meets AC problems in Charleston
When your air conditioner fails during Charleston’s intense summer heat, it quickly becomes more than an inconvenience—it’s an emergency that affects your entire household. Those sweltering days with 90+ temperatures and high humidity demand a functioning cooling system, and delays in repairs can make your home unbearable
Reliable AC repair expertise for Charleston’s demanding climate
Emergency Same-Day Service
We understand AC breakdowns create urgent situations, especially during Charleston’s hottest months, so we prioritize emergency calls and arrive prepared to fix most problems immediately.
Comprehensive Diagnostic Testing
Advanced testing equipment pinpoints exactly what’s wrong with your AC system, so you get targeted repairs instead of expensive guesswork that wastes your time and money.
Fully Stocked Service Trucks
Our technicians carry common AC parts, refrigerants, and specialized tools needed for most Charleston repairs, allowing us to complete fixes during the first visit.
All Brand Expertise
We repair every major AC manufacturer including Carrier, Trane, Lennox, Goodman, and Rheem, with decades of experience troubleshooting systems throughout the Charleston area.
Refrigerant Leak Detection
Specialized leak detection equipment finds even tiny refrigerant leaks that cause poor cooling and high electric bills, ensuring permanent repairs rather than temporary Band-Aid solutions.
Electrical System Repairs
Licensed electrical work fixes faulty wiring, failed capacitors, burned contactors, and other electrical problems that commonly cause AC failures in Charleston’s challenging climate.
“Our AC started making a terrible grinding noise late Friday afternoon before a holiday weekend. I was certain we’d be sweltering for days, but Blanton & Sons had a technician at our Charleston home within two hours. He identified a failing fan motor, had the part on his truck, and had us cooling again before dinner. Their emergency service saved our weekend!”

When to call for AC repair in Charleston
No Cool Air Production
When your AC runs but produces warm or room-temperature air, you likely have refrigerant leaks, compressor problems, or airflow issues that need immediate professional repair.
Strange Noises During Operation
Grinding, squealing, banging, or clicking sounds from your AC indicate mechanical problems that will cause expensive damage if not repaired quickly.
Frequent On-Off Cycling
Systems that turn on and off constantly struggle with electrical problems, thermostat issues, or refrigerant levels that waste energy and reduce comfort.
Ice Formation on Unit
Ice buildup on your indoor or outdoor AC components indicates serious airflow or refrigerant problems that can damage expensive compressor components permanently.
High Humidity Despite AC Running
When your AC can’t control Charleston’s humidity levels, you may have sizing problems, ductwork leaks, or equipment malfunctions affecting your comfort.
