Get answers to common questions about hvac services in Duncan, South Carolina.
For a full system replacement (air conditioner and furnace or heat pump) in a standard Duncan home, homeowners can expect a typical range of $6,500 to $12,000. This range accounts for the size of your home, the system's efficiency (SEER rating), and the complexity of the installation. Given our hot, humid Upstate SC summers, investing in a higher-efficiency unit (16+ SEER) can offer significant long-term savings on energy bills despite a higher upfront cost.
The ideal times are during the mild shoulder seasons of early spring (March-April) and early fall (September-October). Scheduling service during these periods ensures your system is fully tuned up before the intense summer heat and humidity arrive, and it helps you avoid the peak demand rush when HVAC companies are busiest with emergency breakdown calls. This often leads to better scheduling flexibility and potential promotional pricing.
While state-level mechanical codes apply, specific permits for HVAC replacement are typically handled by your licensed contractor through Spartanburg County Building Codes. Importantly, check for available rebates; while Duke Energy serves Duncan and often offers rebates for high-efficiency heat pumps or air conditioners, you should also inquire with your contractor about any local utility or manufacturer promotions specific to our area to maximize savings.
Always verify that the company is licensed, insured, and has a strong local reputation. Look for contractors who are NATE-certified and have extensive experience with homes in Spartanburg County, as they will understand our specific climate challenges. Ask for references from recent jobs in neighborhoods like Fairforest or Lyman, and ensure they provide detailed, written estimates that include a Manual J load calculation to properly size your system.
Given Duncan's high pollen counts and humidity, the most common culprits are a dirty air filter restricting airflow or a clogged outdoor condenser coil. The coil can become matted with cottonwood, grass clippings, and other debris, severely reducing its ability to release heat. Regular cleaning of the outdoor unit and monthly filter changes (especially during peak seasons) are critical first steps before assuming a major refrigerant issue or component failure.
