FAQs
What does it mean that your technicians are NATE-certified?
NATE (North American Technician Excellence) certification is the highest industry credential for HVAC professionals. Every technician must pass rigorous core and specialty exams that test real-world knowledge of heating, cooling, ventilation, and refrigeration equipment. When you invite a NATE-certified technician into your Charleston home, you know the work will be completed to national standards, manufacturer specifications, and local code. It also means faster, more accurate diagnostics, fewer callbacks, and better protection for your equipment warranty.
Which types of heating systems do you repair in Charleston?
Our team services virtually every residential and light-commercial heating system found in the Lowcountry: gas furnaces, electric furnaces, heat pumps, dual-fuel hybrids, ductless mini-splits, package units, and geothermal heat pumps. We work on all major makes and models, including Carrier, Trane, Lennox, Rheem, Goodman, and more. Whether your system is 30 years old or brand-new, our NATE-certified technicians have the training and diagnostic tools to get it running safely and efficiently.
How fast can you respond to an emergency heat repair call?
Charleston’s damp winters can feel chilly, so we keep fully stocked service vans on the road 24/7. For most emergency calls placed before 10 p.m., we can be at your door within 2–4 hours, often sooner inside the I-526 loop. After-hours, weekends, and holidays we maintain an on-call staff, so you never have to endure a night without heat. Non-emergency appointments are usually scheduled for the same or next business day.
Do you guarantee your heat repair work?
Yes. All repairs come with a 1-year parts and labor warranty, and many OEM replacement parts carry longer manufacturer warranties. If the exact same part we replaced fails within 12 months, we’ll fix it again at no charge. In addition, every service visit includes our 100 % Satisfaction Guarantee—if you’re not happy with the workmanship, we’ll make it right or refund the repair cost.
How much does a typical heat repair cost?
Pricing depends on the nature of the failure, the age of your equipment, and whether specialty parts are required, but most residential heat repairs in Charleston fall between $150 and $650, parts and labor. Before any work begins, we provide a flat-rate, upfront quote so you know the exact cost. We also waive the diagnostic fee when you proceed with the recommended repair and offer financing for larger fixes such as heat-exchanger replacements.
How can I prevent future heating breakdowns?
The best way to avoid unexpected repairs is to schedule professional maintenance every fall. Our 21-point heating tune-up cleans vital components, checks safety controls, calibrates thermostats, and tests for carbon monoxide leaks. Customers who join our Comfort Club receive these tune-ups, priority scheduling, and 15 % off repairs. In between visits, change or wash your air filter monthly, keep supply vents clear, and call us at the first sign of unusual noises, odors, or rising energy bills.
