Indiana: HVAC Replacement Cost Calculator

Most Indiana homeowners spend between $7,500 and $13,000 to replace a gas furnace and central air conditioner at the same time, while a standalone furnace runs $3,500 to $7,000 and a central AC replacement runs $4,000 to $7,500. Heat pumps land between $6,000 and $12,000 installed. These are installed prices, meaning equipment plus labor, and Indiana labor rates sit right at the national average with HVAC technicians earning about $31.30 per hour.

Worked example

Take a 1,900-square-foot two-story home outside Indianapolis with a 21-year-old gas furnace and a matched AC condenser that finally failed in July. Because both units are original and share the same ductwork and coil cabinet, the homeowner replaces them together as a single job. With a mid-efficiency furnace, a standard-efficiency condenser, a new evaporator coil, a new line set, and a day and a half of labor for a two-person crew, this project lands near the middle of Indiana's $7,500 to $13,000 combo range, around $9,500 to $10,500. Adding a variable-speed furnace or a higher-SEER2 condenser would push it toward the top of that range.

Frequently asked questions

How much does it cost to replace a furnace and AC together in Indiana?

Replacing both at once typically costs $7,500 to $13,000 installed in Indiana. Doing them as one job is usually cheaper than two separate projects because the crew only makes one trip, sets up once, and matches the coil to the condenser correctly the first time.

Does a heat pump make sense in Indiana's climate?

Indiana sits in climate zone 4, a mixed climate with real winters but not extreme sustained cold, so heat pumps are a workable option here. Installed costs run $6,000 to $12,000, and many Indiana homes pair a heat pump with an existing or new gas furnace so the furnace handles the coldest stretches.

Why do HVAC quotes in Indiana vary by thousands of dollars?

Most of the spread comes from equipment tier and job complexity, not the state itself. Indiana labor costs are almost exactly at the national average, with technicians earning roughly $31.30 per hour, so a $3,500 gap on a furnace quote usually reflects efficiency rating, blower type, or extra work like duct modifications, venting changes, or electrical upgrades.

What does a ductless mini split cost in Indiana?

Ductless mini splits in Indiana run $3,500 to $10,000 installed. A single indoor head serving one room or an addition sits at the low end, while a multi-zone system with three or four heads covering most of a house pushes toward $10,000.
