FAQs
How quickly can your technicians respond to a heating or AC emergency in Charleston?
Because our service teams are based right here in Charleston, most emergency calls are answered within 2‒4 hours—often sooner during normal business hours. We maintain fully stocked service vehicles, so in the majority of cases we can diagnose the problem and complete the repair in a single visit.
Are your HVAC technicians licensed and insured in South Carolina?
Yes. Every technician holds a current South Carolina Mechanical Contractor license with an HVAC classification, undergoes annual continuing-education courses, and is fully covered by general liability and workers’ compensation insurance. Copies of all documentation are available upon request for your peace of mind.
What brands and systems do your technicians service?
Our experienced techs are trained to work on all major residential and light-commercial HVAC brands, including Trane, Carrier, Lennox, Rheem, Bryant, Goodman, Daikin, Mitsubishi, and more. We service central AC units, gas and electric furnaces, heat pumps, ductless mini-splits, air handlers, and indoor air-quality accessories such as humidifiers and UV lights.
Do you offer preventative maintenance plans and what do they include?
Yes. Our Comfort Guard Maintenance Plan provides two tune-ups per year (spring AC and fall heating), priority scheduling, a 15% discount on repairs, no overtime fees, and documented inspection reports. Each visit includes cleaning condenser coils, checking refrigerant charge, testing safety controls, tightening electrical connections, and verifying thermostat calibration.
How energy-efficient can a new HVAC installation be and will it lower my utility bills?
Today’s high-efficiency air conditioners and heat pumps reach SEER2 ratings of 18–24, while gas furnaces achieve up to 98% AFUE. Replacing a 10–15-year-old system with a high-efficiency model can cut your heating and cooling costs by 25–40%. We perform a free load calculation to size the equipment correctly and can show projected savings before you commit.
What should I expect during a service visit from your technicians?
You’ll receive a text or call with your technician’s name, photo, and estimated arrival time. Upon arrival, the tech will wear shoe covers, protect work areas, and conduct a thorough diagnostic. Once the issue is identified, you’ll get a clear, upfront price before any work begins. After the repair or tune-up, we run the system through a full operational check, answer any questions, and leave the workspace clean.
