FAQs
How do I know it’s time to replace my HVAC system rather than repair it?
In Charleston’s hot, humid climate, air-conditioners and heat pumps work harder than the national average. If your equipment is 10–15 years old, needs frequent or expensive repairs, struggles to keep set temperatures, or has a SEER/EER rating well below today’s standards, replacement is usually the most cost-effective choice. A new high-efficiency unit can cut cooling costs by 20-40 %, often paying for itself in utility savings within 4-6 years.
What efficiency ratings should I look for when choosing a new unit?
Starting in 2023, the Southeast region (including South Carolina) requires minimum 14.3 SEER2 for air conditioners and 15.0 SEER2 for heat pumps. For the best return on investment, many Charleston homeowners opt for 16–20 SEER2 systems with an HSPF2 of 7.5 or higher. Higher SEER2/HSPF2 units consume less energy, run quieter, control humidity better, and qualify for rebates and tax credits.
Are there any rebates or tax incentives for installing an energy-efficient HVAC system in Charleston?
Yes. Dominion Energy South Carolina offers rebates up to $700 for qualifying high-efficiency replacements. The federal Inflation Reduction Act (IRA) provides a 30 % tax credit (up to $2,000) for ENERGY STAR certified heat pumps and a separate credit for advanced electric panels if needed. The South Carolina State Energy Office also issues occasional incentives for duct sealing and smart thermostats. We’ll handle all paperwork and make sure you receive every available dollar.
Which type of system works best in Charleston’s coastal environment?
Variable-speed heat pumps paired with a gas furnace (dual-fuel) or a high-efficiency coastal-rated heat pump alone are popular choices. Variable-speed compressors adapt output to match humidity loads, giving superior moisture removal on muggy days. Coastal-rated units include epoxy-coated coils and stainless hardware to resist salt-air corrosion common near the harbor and barrier islands.
Will a new HVAC system improve my indoor air quality?
Absolutely. Modern systems sustain lower indoor humidity (ideally 45–50 %), reducing mold risk. They’re compatible with MERV 13-16 filters, whole-home dehumidifiers, UV lights, and electronic air cleaners. Our installation includes a load calculation and duct inspection, ensuring proper airflow and sealing to keep pollutants and coastal allergens out of the living space.
How long does the replacement process take, and will I be without heating or cooling?
A typical residential replacement takes one full day on-site, including removal of the old equipment, installation of the new condenser/air handler or furnace, refrigerant charging, and start-up testing. We pre-fabricate duct transitions and pull permits in advance to minimize downtime. Most homeowners are without AC or heat for only 3–6 hours, and we schedule around severe-weather forecasts to keep you comfortable.
