Louisiana: HVAC Replacement Cost Calculator

Replacing an HVAC system in Louisiana typically runs $4,000 to $7,500 for a central air conditioner alone, $7,500 to $13,000 for a matched AC and gas furnace, and $6,000 to $12,000 for a heat pump. Labor here runs about 12% below the national average, with HVAC technicians earning around $27.35 per hour, which keeps installed prices somewhat lower than in higher-wage states. Where you land inside each range depends mostly on tonnage, equipment efficiency, and how much of the existing ductwork and electrical needs to be reworked.

Worked example

Take a 1,900-square-foot single-story home outside Baton Rouge with a 15-year-old split system and usable ductwork already in place. The homeowner replaces both the condenser and the gas furnace with a standard-efficiency matched set, reusing the existing plenum and line set where possible. That job lands near the middle of the state's $7,500 to $13,000 AC-plus-furnace range, around $9,500 to $10,500 installed. Adding a higher-efficiency condenser, a full duct replacement, or a difficult attic install pushes the same house toward the $13,000 end.

Frequently asked questions

How much does it cost to replace an HVAC system in Louisiana?

Central air conditioning replacement runs $4,000 to $7,500 installed, while a complete AC and gas furnace changeout runs $7,500 to $13,000. A heat pump falls between at $6,000 to $12,000, and a ductless mini split ranges from $3,500 to $10,000 depending on how many indoor heads you need.PLACEHOLDER

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

Louisiana sits in climate zone 2, where winters are short and mild, so a heat pump can handle nearly all of the heating load without a large backup system. At $6,000 to $12,000 installed, a heat pump also overlaps the low end of the $7,500 to $13,000 AC-plus-furnace range, so it is often the cheaper path when you are replacing both pieces at once.

Why is HVAC installation cheaper in Louisiana than in other states?

Labor is the main reason. Louisiana's labor index is 0.88, meaning installation labor costs roughly 12% less than the national average, and HVAC technicians here average about $27.35 per hour. Equipment prices are national, so the savings show up mostly on the labor side of the quote.

Can I just replace the AC and keep my existing furnace?

Yes, and it is the cheapest route at $4,000 to $7,500 versus $7,500 to $13,000 for both units. It usually makes sense when the furnace is significantly newer than the AC, but if both are the same age you will likely pay twice for labor within a few years.

When does a ductless mini split make sense in Louisiana?

Mini splits run $3,500 to $10,000 and work well for homes without existing ductwork, converted garages, additions, or rooms that never cool evenly. A single-zone unit sits near the low end of that range, while a multi-zone system covering several rooms approaches $10,000.
