Baton Rouge, Louisiana: HVAC Replacement Cost Calculator

Most Baton Rouge homeowners spend between $4,000 and $7,500 to replace a central air conditioner, or $7,500 to $13,000 for a full AC and gas furnace system. Labor here runs about 12% below the national average, with local HVAC technicians earning around $27.35 an hour, which keeps installed prices lower than in many metro areas. Because Baton Rouge sits in climate zone 2, cooling capacity and humidity control drive most equipment decisions, not heating output.

Worked example

Take a 1,900-square-foot single-story home in the Broadmoor area with an aging 3.5-ton split system and a gas furnace in the attic. Replacing both with a mid-efficiency matched system, reusing the existing ductwork and line set, would typically land near the middle of the $7,500-$13,000 range — roughly $9,500 to $10,500 installed. If the attic ductwork is leaking or undersized and needs partial replacement, or the homeowner upgrades to a variable-speed air handler for better humidity control, the job pushes toward the $13,000 end.

Frequently asked questions

Is a heat pump worth it in Baton Rouge instead of an AC and gas furnace?

Baton Rouge's climate zone 2 winters are mild enough that a heat pump can handle most heating days without a separate furnace. Installed costs run $6,000 to $12,000 for a heat pump versus $7,500 to $13,000 for a matched AC and gas furnace, so the upfront numbers overlap closely and the decision usually comes down to your existing gas service and duct layout.

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

A central air conditioner replacement typically runs $4,000 to $7,500 installed in Baton Rouge. Straightforward swaps on existing ductwork with no electrical or pad work sit near the low end, while larger tonnage, higher-efficiency equipment, or attic access issues move you toward $7,500.

What does a gas furnace replacement cost in Baton Rouge?

Gas furnace replacement in Baton Rouge generally costs $3,500 to $7,000 installed. Heating loads here are light compared to northern states, so many homes need only a modestly sized furnace — the higher end of the range usually reflects difficult attic or closet installs, venting changes, or higher-efficiency models.

Are ductless mini splits a good option for Baton Rouge homes?

Ductless mini splits run $3,500 to $10,000 in Baton Rouge and make the most sense for additions, converted garages, sunrooms, or older homes without usable ductwork. A single-zone system for one room sits near the low end, while multi-zone setups covering several rooms approach $10,000.
