Birmingham, Alabama: HVAC Replacement Cost Calculator

Replacing an HVAC system in Birmingham 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 suit Birmingham's mild Zone 3 winters well, land between $6,000 and $12,000 installed. Local labor rates run about 21% below the national benchmark, with HVAC technicians in the area earning around $24.67 per hour, which keeps installation costs lower here than in many metros.

Worked example

Take a 1,900-square-foot brick ranch in Homewood with an 18-year-old split system and existing ductwork in decent shape. The homeowner replaces both the condenser and the gas furnace with a mid-efficiency matched set. With no duct rework and a straightforward one-day changeout, this job lands near the middle of the $7,500 to $13,000 range for an AC-plus-furnace replacement — roughly $9,500 to $10,500. Adding a variable-speed blower, a higher SEER2 condenser, or repairing crushed attic duct runs would push it toward the top of that range.

Frequently asked questions

Is a heat pump a good choice in Birmingham?

Birmingham sits in climate zone 3, where winters are mild enough that a heat pump can handle most heating hours without heavy reliance on backup heat. Installed costs run $6,000 to $12,000, which is higher than a standalone AC but replaces both your heating and cooling equipment in one purchase.

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

Labor in the Birmingham market indexes at 0.79, or about 21% below the national benchmark, with local HVAC technicians earning around $24.67 an hour. Since labor is a large share of any installation, that gap shows up directly in your quoted price — equipment costs, however, are set nationally and don't vary much by city.

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

A central AC replacement in Birmingham runs $4,000 to $7,500 installed. That assumes your furnace or air handler is recent enough to pair with a new condenser; if the indoor unit is also aging, most contractors will recommend replacing both, which moves you into the $7,500 to $13,000 range.

Are ductless mini splits worth considering for a Birmingham home?

Mini splits cost $3,500 to $10,000 in Birmingham depending on how many indoor heads you need. They make the most sense for additions, converted garages, bonus rooms over the garage, or older homes where running new ductwork would be expensive or invasive.
