Montgomery, Alabama: HVAC Replacement Cost Calculator

Replacing an HVAC system in Montgomery, Alabama typically runs $4,000 to $7,500 for a central air conditioner alone, or $7,500 to $13,000 for a matched AC and gas furnace pair. Heat pumps, which handle both heating and cooling in Montgomery's mild Zone 3 climate, land between $6,000 and $12,000 installed. Local labor costs sit about 21% below the national average, with HVAC technicians in the area earning around $24.67 per hour, which keeps installation charges lower here than in most metro markets.

Worked example

Take a 1,900 square foot single-story home in east Montgomery with existing ductwork in decent shape and a 15-year-old split system that has failed. The homeowner replaces both the outdoor condenser and the gas furnace with a mid-efficiency matched pair. With no duct replacement needed and Montgomery's below-average labor rates, this job would land near the middle of the $7,500 to $13,000 AC-plus-furnace range, roughly $9,500 to $10,500 installed. Adding new supply runs, a larger return, or stepping up to a higher-SEER2 condenser would push it toward the $13,000 end.

Frequently asked questions

Is a heat pump or a gas furnace better for Montgomery's climate?

Montgomery sits in climate zone 3, where winters are short and mild, so a heat pump can cover heating needs most of the year without backup heat running constantly. Heat pumps here run $6,000 to $12,000 installed versus $7,500 to $13,000 for an AC and gas furnace combination, and the single-system approach means one unit to maintain instead of two.

Why does HVAC replacement cost less in Montgomery than the national average?

Labor in the Montgomery market runs about 21% below the national benchmark, with local HVAC technicians earning around $24.67 per hour. Since labor is usually a third or more of a total installation, that gap is the main reason a Montgomery homeowner pays less than someone in a high-cost coastal metro for the same equipment.

How much does it cost to replace just the air conditioner in Montgomery?

A standalone central AC replacement in Montgomery runs $4,000 to $7,500 installed. You would land at the low end with a straightforward same-size swap on an existing pad and matching indoor coil, and toward the high end with a larger tonnage unit, a new coil and line set, or higher-efficiency equipment.

Are ductless mini splits worth it for a Montgomery home?

Ductless mini splits run $3,500 to $10,000 in Montgomery depending on how many indoor heads you install. They make the most sense for additions, converted garages, bonus rooms over garages, or older Montgomery homes where adding ductwork would mean tearing into walls and ceilings.
