FAQs
What type of HVAC system works best for Charleston’s hot, humid summers and mild winters?
A high-efficiency heat pump is often the best all-around choice for the Lowcountry. It provides cost-effective cooling during our long, humid summers and delivers reliable heating on those cool but not extreme winter days. For homes that already have a gas line, a dual-fuel (hybrid) system—combining an electric heat pump with a high-efficiency gas furnace—can deliver optimal comfort and lower utility bills by switching to the most economical energy source as outdoor temperatures change.
How frequently should I schedule maintenance for my heating and air conditioning system?
Charleston’s salt air and high humidity place extra stress on HVAC equipment, so we recommend two professional tune-ups per year: one in early spring before cooling season and one in early fall before heating season. Regular maintenance keeps components clean, maintains efficiency, identifies small issues before they become costly repairs, and is required by most manufacturers to keep warranties valid.
What can I do about the high indoor humidity common in coastal South Carolina?
Persistent indoor humidity above 50–55 % can foster mold, dust mites, and that sticky feeling inside your home. A well-sized air conditioner or heat pump should de-humidify as it cools, but if humidity remains high you can: (1) install a whole-home dehumidifier that ties into your ductwork, (2) seal duct leaks and add attic insulation to reduce moisture infiltration, (3) use bathroom and kitchen exhaust fans while cooking or showering, and (4) schedule an HVAC inspection to ensure the system is properly charged and draining condensate.
How do I know what size HVAC unit my home needs?
Proper sizing is determined by a Manual J load calculation, which takes into account square footage, insulation levels, window area, orientation, local climate data for Charleston, and household occupancy. Going strictly by tonnage rules of thumb can result in an oversized system that short-cycles, wastes energy, and fails to dehumidify. A certified technician should perform the load calculation and present options that meet the required capacity with the highest efficiency your budget allows.
Are there local or federal incentives for upgrading to high-efficiency HVAC equipment?
Yes. Through 2032, the federal Inflation Reduction Act offers tax credits of up to 30 % of equipment and installation costs (capped at $2,000 per year) for qualifying ENERGY STAR heat pumps and advanced air conditioners. South Carolina Electric & Gas customers may also qualify for rebates on high-efficiency heat pumps, smart thermostats, and duct sealing. We’ll guide you through available incentives, provide necessary paperwork, and make sure your new system meets all efficiency requirements.
What warning signs indicate my HVAC system may need repair or replacement?
Call for service if you notice: • uneven temperatures or poor airflow from vents; • frequent cycling on and off; • energy bills suddenly rising; • strange noises (grinding, squealing, or rattling); • musty or burning odors; • excessive condensation or water around the air handler; or • the system is 10–15 years old and requires repeated repairs. Our technicians will diagnose the issue, outline repair options, and let you know when replacement would be the more economical long-term solution.
