Get answers to common questions about hvac services in Jefferson, South Carolina.
For a full system replacement in Jefferson, homeowners can expect to pay between $5,000 and $12,000, depending on the home's size, system efficiency (SEER rating), and complexity of installation. Our humid summers and occasional cold snaps mean a properly sized, efficient system is crucial for comfort and energy bills. Always get itemized estimates from local contractors that include removal of the old unit, new equipment, labor, and any necessary duct modifications.
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 ready for the peak summer heat and winter chill, and you'll find greater technician availability and potentially better pricing compared to the high-demand summer and winter emergency periods.
While Jefferson follows standard South Carolina building codes, there are no unique local ordinances for residential HVAC. However, homeowners should always verify their contractor is licensed by the South Carolina Department of Labor, Licensing and Regulation (SC LLR). For rebates, check with Duke Energy or your local utility provider for potential incentives on high-efficiency systems, which are highly beneficial given our climate.
Look for a locally established company with strong community references. Verify their SC Mechanical Contractor license and insurance. A reputable provider will perform a detailed Manual J load calculation specific to your home's construction and our local climate, not just recommend the same size as your old unit. This ensures proper sizing for efficiency and longevity.
This is often caused by a combination of inadequate insulation/air sealing in the attic and dirty evaporator coils or refrigerant issues. Jefferson's high summer humidity forces the system to work harder to remove moisture. First, ensure your air filter is clean and outdoor unit is clear of debris. If the problem persists, a local technician should check refrigerant levels and inspect ductwork for leaks, which are common in older homes.
