FAQs
How do I know if my heat pump needs repair?
Watch for higher-than-normal electric bills, rooms that feel too warm or too cold, weak airflow, ice forming on the outdoor unit, unusual noises, or musty/burning odors. Because Charleston’s humid, salty air can be harsh on equipment, these symptoms often appear sooner here than in drier climates. If you notice any of them, shut the system off to prevent additional damage and call our certified technicians for an inspection.
What kinds of heat-pump problems can you fix in the Charleston area?
Our team handles everything from simple thermostat malfunctions to complex mechanical failures. Common repairs include refrigerant leaks, frozen or dirty coils, failed compressors, reversing-valve problems that prevent switching between heating and cooling, blower motor or capacitor failures, condensate drain clogs, and electrical or control-board issues. We service air-source, ductless mini-split, and packaged heat-pump systems from every major brand, using factory-authorized parts whenever possible.
How quickly can you get my heat pump running again?
For customers in Charleston, Mount Pleasant, North Charleston, and surrounding communities, we offer same-day service when you call before noon. Our dispatchers send fully stocked service vans, allowing us to fix about 90 percent of problems on the first visit. Typical arrival time is 2–4 hours after your call, and we’ll give you a 30-minute call-ahead so you’re not waiting all day.
Are your technicians qualified to work on all heat-pump brands?
Yes. Every technician is NATE-certified and EPA Section 608 licensed. We undergo ongoing factory training for Trane, Carrier, Lennox, Rheem, Goodman, Mitsubishi, Daikin, Bosch, and other leading manufacturers. That means your repair meets both manufacturer specifications and the South Carolina Mechanical Code, keeping warranties intact and ensuring safe, efficient operation.
Do you offer after-hours or emergency heat-pump repair?
Absolutely. Charleston’s weather can change quickly, so we provide 24/7 emergency service—including nights, weekends, and holidays. A small dispatch fee applies outside standard hours, but Comfort Club maintenance members pay no overtime premium. If a specialty part must be ordered, we can install temporary electric space heaters at no extra charge to keep you comfortable until repairs are finished.
How does routine maintenance reduce the need for costly repairs?
A bi-annual tune-up cleans coils, checks refrigerant levels, tightens electrical connections, lubricates motors, calibrates thermostats, and flushes the condensate line. In coastal Charleston, salt, sand, and pollen build up quickly on outdoor coils; removing them prevents corrosion, boosts efficiency by up to 20 %, and extends compressor life. Regular maintenance also keeps manufacturer warranties valid and helps us catch small issues before they turn into expensive breakdowns during peak heating or cooling seasons.
