Charleston, West Virginia: HVAC Replacement Cost Calculator

Replacing an HVAC system in Charleston, West Virginia typically runs $7,500 to $13,000 for a matched gas furnace and central air conditioner, installed. Standalone equipment costs less — a gas furnace alone falls between $3,500 and $7,000, while central AC alone runs $4,000 to $7,500. Charleston's labor index sits at 0.80, meaning installation labor here costs about 20% less than the national average, with local HVAC technicians earning around $24.85 an hour.

Worked example

Take a 1,900-square-foot two-story home in the South Hills area with an aging gas furnace and a 15-year-old AC condenser sharing the same ductwork. Because both units are at end of life, the homeowner replaces them together as a matched system rather than one at a time. With serviceable existing ducts, a standard-efficiency furnace, and a mid-tier condenser, this job lands near the middle of Charleston's $7,500 to $13,000 range — roughly $9,500 to $10,500. Adding a high-efficiency condenser, a new line set, or duct repairs in a tight crawlspace would push it toward the $13,000 end.

Frequently asked questions

Is a heat pump a good choice in Charleston's climate?

Charleston sits in climate zone 4, a mixed climate where winters are cold but not extreme, which is the range where modern heat pumps perform well. Installed costs here run $6,000 to $12,000, higher than a gas furnace alone at $3,500 to $7,000. Many Charleston homeowners pair a heat pump with existing gas backup heat for the coldest stretches.

Why is HVAC replacement cheaper in Charleston than in bigger cities?

Labor is the main reason. Charleston's labor index is 0.80, about 20% below the national average, and local HVAC technicians earn roughly $24.85 per hour. Equipment prices are fairly consistent nationwide, so the savings show up in the installation portion of your quote.

How much does ductless mini-split installation cost in Charleston?

Ductless mini-splits in Charleston run $3,500 to $10,000 installed. The low end covers a single indoor head for one room or an addition, while multi-zone systems serving several rooms land at the upper end. They are a common choice for older Charleston homes and finished attics or basements that never had ductwork.

Should I replace my furnace and AC at the same time?

If both units are near the end of their service life, replacing them together usually costs less than two separate jobs. A matched furnace and AC in Charleston runs $7,500 to $13,000, versus $3,500 to $7,000 for the furnace and $4,000 to $7,500 for the AC done separately. You also avoid paying twice for setup, refrigerant line work, and startup labor.
