FAQs
What does it mean to be NATE-certified and why is it important for my Charleston air-conditioning service?
NATE (North American Technician Excellence) certification is the HVAC industry’s most rigorous, nationally recognized credential. To earn it, technicians must pass proctored exams that cover refrigeration principles, heat-transfer, electrical diagnostics, air flow, and regional code requirements. When you hire our NATE-certified professionals, you’re assured that the person working on your system has proven, up-to-date knowledge and can diagnose and repair problems correctly the first time—critical in Charleston’s hot, humid climate where downtime can quickly become uncomfortable and expensive.
How fast can your NATE-certified technicians get to my home or business in Charleston for an AC repair?
Because we keep fully staffed crews stationed throughout the Tri-County area, most customers receive same-day service and, in many cases, within a 2–4-hour window. Dispatch software pinpoints the closest available NATE-certified technician, so you get prompt help whether you live downtown, on James Island, West Ashley, North Charleston, Mount Pleasant, or the surrounding islands.
What types and brands of air-conditioning systems do you service?
Our NATE-certified techs are trained on every major residential and light-commercial brand, including Trane, Carrier, Lennox, Rheem, Goodman, Daikin, Mitsubishi, and Bosch. We handle central split systems, heat pumps, ductless mini-splits, VRF/VRV equipment, rooftop package units, and high-efficiency variable-speed systems. Access to OEM diagnostic tools and an on-truck parts inventory lets us finish most repairs in a single visit.
Do you offer 24/7 emergency air-conditioning service in Charleston?
Yes. Charleston’s summer temperatures routinely exceed 90 °F with humidity levels above 70%, so waiting until morning isn’t always an option. Our emergency line is monitored around the clock. A live dispatcher will gather your information, and an on-call NATE-certified technician will arrive—usually within two hours—to restore cooling, even on weekends or holidays. After-hours rates are quoted up-front, and club-membership customers receive discounted emergency fees.
Can your technicians help lower my energy bills and reduce indoor humidity specific to the Lowcountry climate?
Absolutely. During a diagnostic or maintenance visit, our NATE-certified pros measure static pressure, check refrigerant charge, verify airflow across the evaporator coil, and inspect duct sealing—key factors in both efficiency and moisture removal. We can recommend high-efficiency variable-speed systems, in-line dehumidifiers, or smart thermostats that target Charleston’s swamp-like humidity while cutting energy consumption 15–30%. We also offer duct redesign and insulation services to combat the heat-gain typical of older coastal homes.
What preventive maintenance plans do you offer, and how often should I schedule tune-ups?
We provide flexible Silver, Gold, and Platinum Comfort Plans. Each includes two precision tune-ups per year: one in spring before cooling season and one in fall before heating season. NATE-certified technicians clean coils, calibrate thermostats, test safety controls, tighten electrical connections, and document any emerging issues. Members receive priority scheduling, a 15% repair discount, and extended parts & labor warranties. Regular maintenance can extend equipment life by 5–8 years and maintain peak SEER ratings, saving Charleston homeowners hundreds of dollars annually.
