Columbia, South Carolina: HVAC Replacement Cost Calculator

Most Columbia homeowners replacing an HVAC system pay between $4,000 and $13,000 installed, depending on what they put in. A straight central AC swap runs $4,000 to $7,500, while a heat pump — the most common choice in this part of South Carolina — lands between $6,000 and $12,000 including equipment and labor. Local HVAC labor runs about 13% below the national average, which keeps installation costs here lower than in most metro areas.

Worked example

Take a 1,900 sq ft one-story home in the Forest Acres area with a 14-year-old heat pump that's no longer keeping up through Columbia's long cooling season. The homeowner replaces it with a comparable-capacity heat pump, reusing the existing ductwork and pad, with a new line set and thermostat. That job would land near the middle of the local $6,000 to $12,000 heat pump range — roughly $8,500 to $9,000. Pushing to a higher-efficiency variable-speed unit, or adding duct repairs, moves the number toward the $12,000 end.

Frequently asked questions

Is a heat pump or a gas furnace and AC better for Columbia?

Columbia sits in climate zone 3, where winters are mild enough that a heat pump can handle most heating days without much backup. A heat pump costs $6,000 to $12,000 installed here, versus $7,500 to $13,000 for a matched AC and gas furnace system, so the heat pump is usually both cheaper up front and simpler to install. If your home already has natural gas service and working gas lines, the combo system is still a reasonable option.

How much does it cost to replace just the AC unit in Columbia?

Replacing central air conditioning alone runs $4,000 to $7,500 installed in Columbia. You'd land at the low end with a standard-efficiency unit in an accessible location and usable existing ductwork, and toward $7,500 with a larger or higher-efficiency system. Keep in mind that if your furnace or air handler is the same age, many contractors will recommend replacing both at once.

Why is HVAC installation cheaper in Columbia than in bigger cities?

Labor here runs about 13% below the national average, with HVAC technicians earning roughly $27.14 per hour. Since labor is typically a large share of an installed HVAC price, that gap shows up directly in your quote. Equipment costs, though, are set nationally, so the savings apply mainly to the installation side.

What does a ductless mini split cost in Columbia?

Ductless mini splits run $3,500 to $10,000 installed in the Columbia area. A single-zone system for one room or an addition sits near the bottom of that range, while a multi-zone setup covering several rooms pushes toward $10,000. Mini splits are worth pricing out if you're conditioning a converted garage, sunroom, or older home without existing ductwork.
