Lafayette, Louisiana: HVAC Replacement Cost Calculator

Most Lafayette homeowners spend between $4,000 and $7,500 to replace a central air conditioner, while a full AC and gas furnace changeout runs $7,500 to $13,000 installed. Heat pumps, which handle both cooling and heating in south Louisiana's mild winters, land between $6,000 and $12,000. Labor here runs about 12% below the national average, with local HVAC technicians earning around $27.35 an hour, which helps keep installed pricing on the lower end of national figures.

Worked example

Take a 1,900-square-foot single-story home off Johnston Street with an aging 3-ton split system and ductwork already in decent shape. Replacing it with a straight heat pump — a common choice in Lafayette since it covers cooling all summer and the handful of cold nights each winter — would typically land near the middle of the $6,000 to $12,000 range, around $8,000 to $9,000 installed. If the homeowner keeps the existing gas furnace and swaps only the outdoor condenser and indoor coil, the job drops into the $4,000 to $7,500 central AC range instead.

Frequently asked questions

How much does it cost to replace an AC unit in Lafayette, LA?

Central air conditioning replacement in Lafayette generally runs $4,000 to $7,500 installed, including equipment and labor. Where you land depends on tonnage, efficiency rating, and whether the installer has to modify existing ductwork or the electrical connection.

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

Lafayette 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 gas furnace backup. Installed cost runs $6,000 to $12,000, which is more than a standalone AC but replaces two pieces of equipment at once.

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

If both units are near the end of their life, replacing them together as an AC plus gas furnace system costs $7,500 to $13,000 in Lafayette. That is less than doing two separate jobs later, since the crew is already in the attic or closet and only sets up once.

Why is HVAC installation cheaper in Lafayette than the national average?

Labor in the Lafayette market indexes at about 0.88, or roughly 12% below the national average, with HVAC technicians earning around $27.35 per hour. Since labor is a large share of any replacement job, that discount shows up directly in your installed price.
