Nashville, Tennessee: HVAC Replacement Cost Calculator

Most Nashville homeowners spend between $4,000 and $7,500 to replace a central air conditioner, while a matched AC and gas furnace system runs $7,500 to $13,000 installed. Heat pumps, which handle both heating and cooling in Nashville's climate zone 3, typically land between $6,000 and $12,000. Local HVAC labor runs about 11% below the national average, with installers earning around $27.79 an hour, which helps keep total install pricing moderate compared to larger metros.

Worked example

Take a 1,900-square-foot two-story house in East Nashville with an 18-year-old split system: a gas furnace in the crawlspace and a condenser on the side of the house. The homeowner replaces both at once so the coil and blower are properly matched. With ductwork in usable shape and a straightforward single-stage, mid-efficiency setup, this job lands near the middle of the $7,500 to $13,000 range for an AC plus furnace replacement, roughly $9,500 to $10,500. Pushing to a variable-speed furnace or a higher-SEER2 condenser moves it toward the $13,000 end.

Frequently asked questions

Is a heat pump a good choice in Nashville, or should I stick with a gas furnace?

Nashville sits in climate zone 3, where winters are mild enough that a heat pump can carry most of the heating load without heavy reliance on backup heat. A heat pump runs $6,000 to $12,000 installed and replaces both your AC and furnace with one unit, while a gas furnace alone is $3,500 to $7,000 plus $4,000 to $7,500 for a separate AC. If you already have natural gas service and a working furnace, replacing just the AC is usually the cheaper near-term move.

Why do Nashville HVAC quotes vary by thousands of dollars for the same house?

The spread inside each range, for example $4,000 to $7,500 on a central AC, comes down to system size, efficiency tier, and how much extra work the install requires. Duct repairs, electrical upgrades, a new line set, or a tight crawlspace or attic all push a quote toward the high end. Always compare quotes on the same equipment tonnage and efficiency rating, not just the bottom-line price.

How much does labor add to an HVAC replacement in Nashville?

Nashville HVAC labor runs at about 0.89 of the national average, with technicians earning roughly $27.79 per hour. That below-average labor index is one reason Nashville install totals tend to sit a bit under what homeowners pay in higher-cost metros. Labor is already baked into the ranges on this page since all figures are installed costs.

What does a ductless mini split cost in Nashville and when does it make sense?

Ductless mini splits in Nashville run $3,500 to $10,000 installed, with the low end covering a single indoor head and the high end covering multi-zone setups. They are a good fit for finished attics, bonus rooms over garages, sunrooms, and older Nashville homes with no existing ductwork. For a home that already has usable ducts, a conventional heat pump or AC and furnace system is usually the better value.
