The prevalence of older homes leads to significant demand for ductwork sealing, replacement, and system retrofits to improve efficiency.

Get answers to common questions about hvac services in Union, South Carolina.
For a full system replacement in Union, homeowners can expect a typical range of $5,000 to $12,000, depending on the home's size, system efficiency (SEER rating), and brand. 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 avoids the peak summer demand when HVAC companies are busiest with emergency breakdowns in the 90°F+ heat. Planning ahead ensures you get timely service and potentially better scheduling flexibility and pricing.
While Union follows standard South Carolina building and mechanical codes, there are no unique city-specific HVAC permits beyond typical county requirements. However, South Carolina residents may qualify for rebates from utility providers like Duke Energy for installing high-efficiency systems. Always ask your local HVAC contractor about current utility and federal tax credit opportunities to offset upgrade costs.
Look for a licensed, insured, and locally established company with strong community references. Verify they hold a South Carolina Mechanical Contractor license. A reputable Union contractor will perform a detailed load calculation (Manual J) specific to our climate and your home's construction, not just match the old unit's size, to ensure optimal efficiency and dehumidification.
This is often related to the high humidity levels common in Union's climate. An oversized system, a failing component, or low refrigerant can prevent proper dehumidification, causing the system to "short cycle" or run inefficiently. Proper maintenance, including coil cleaning and checking refrigerant levels, is essential. A correctly sized system with a variable-speed blower can greatly improve humidity control.
