Get answers to common questions about hvac services in Marietta, South Carolina.
For a full system replacement (air conditioner and furnace or heat pump) in Marietta, homeowners can expect a typical range of $6,500 to $12,000, depending on system size, efficiency rating, and home complexity. The humid Upstate SC climate makes proper sizing and installation critical to manage moisture, which can influence the choice and cost of equipment. Always get multiple itemized quotes from licensed local contractors to ensure a fair price for quality equipment and labor.
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 intense Upstate SC summer heat and humidity or the occasional winter cold snap, and you'll find greater technician availability and potentially better pricing than during the peak summer or winter emergency periods.
South Carolina requires all HVAC contractors to be licensed by the SC Department of Labor, Licensing and Regulation (LLR)—always verify this license. While state-specific rebates are limited, local Marietta residents should check with Duke Energy for potential rebates on high-efficiency heat pumps or air conditioners, which are highly beneficial for our climate. Additionally, Greenville County may have specific permitting requirements for new system installations.
Prioritize contractors with a strong local presence, verified SC Master HVAC license, and positive reviews from neighbors in the Upstate. A reputable Marietta contractor will perform a detailed Manual J load calculation to correctly size your system for your home's specific layout and our local climate, not just match the old unit's size. They should also be familiar with handling the high pollen levels and humidity common to our region.
It is common for a properly sized heat pump to run in longer cycles during peak summer heat and humidity, which is necessary to effectively remove moisture from the air inside your home. However, non-stop operation or failure to reach the thermostat setting could indicate an undersized unit, low refrigerant, or a maintenance issue like a dirty coil. Given our extended humid season, having a professional evaluate its performance is recommended to ensure efficiency and comfort.
