Birmingham's price band
Birmingham is pricier than 49% of the 195 US metros we price for HVAC work.
Expect $3,650–$8,200 for a new 3-ton central AC in Birmingham and $5,650 for a typical job. Homes without ducts usually go ductless: $4,200–$9,400 for two zones and $7,500–$16,900 for four.
Birmingham's long, humid summers make cooling the main load, and heat pumps suit the mild winters. Under the federal Southeast standard, a new split central AC under 45,000 BTU must be at least 14.3 SEER2.
Prices on this page are installed: equipment, labor, removal of the old unit and startup. A permit ($90–$230), a new line set ($180–$600) or duct repairs may be extra, so ask. Labor is usually 40–60% of the bill.

Prices cover the Birmingham metro: the city and its close suburbs. Outlying towns can run a little lower; Downtown & Avondale runs a little higher.
HVAC prices across Birmingham
Same city, four kinds of job. Older buildings in Downtown & Avondale take longer, bigger homes in Hoover, Homewood & the suburbs need bigger systems, and North Birmingham & Eastlake usually comes in at or under the city typical.
Downtown & Avondale
- Installed
- $3,850–$9,000 installed
- Typical job
- $5,350–$7,150 / 3-ton AC swap
Condos, row houses and older buildings. Condensers often sit on roofs or in tight side yards, and paid parking, freight elevators and building rules all add labor.
West End & Ensley
- Installed
- $3,700–$8,600 installed
- Typical job
- $5,200–$6,800 / 3-ton AC swap
Older houses next to new infill. The swap itself is standard; the extras are undersized ducts, old wiring and line sets that need replacing for the new refrigerant.
North Birmingham & Eastlake
- Installed
- $3,650–$8,200 installed
- Typical job
- $5,100–$6,500 / 3-ton AC swap
Established neighborhoods of single-family homes. Most jobs are a standard swap at the city's typical price.
Hoover, Homewood & the suburbs
- Installed
- $3,650–$8,700 installed
- Typical job
- $5,100–$6,900 / 3-ton AC swap
Larger homes on easy lots. The ton count drives the price more than access, and two-system homes are common.
Real-world HVAC costs in Birmingham
Here's what common HVAC jobs cost in Birmingham in 2026, a 3-ton central AC replacement on existing ducts, installed.
Swap a 3-ton AC on good ducts
Same spot, same size, matched indoor coil, old unit hauled away. Most Birmingham jobs land near $5,650; a 17+ SEER2 unit adds about $1,900.
Replace the AC and gas furnace together
The usual move when both are 15+ years old. One install, one warranty, a matched system. Typical is $9,200.
Switch from AC + furnace to a heat pump
A 3-ton heat pump on existing ducts, typically $7,500. Keeping the furnace as backup (dual-fuel) runs $6,650–$15,950.
Cool one room with a mini-split
A 12,000 BTU single-zone mini-split for a bedroom, office or addition, typically $3,650. A 9,000 BTU unit for a small room is $2,050–$4,500.
Cool a whole home with no ducts
A 4-zone ductless system, typically $11,250. Adding ducts for central AC instead costs $2,300–$8,850 before the equipment.
How much does HVAC cost in Birmingham?
$3,650–$8,200 installed, with $5,650 the typical Birmingham price. The spread is mostly the equipment tier and the install: a standard unit on a ground pad is a one-day job, while rooftop condensers, attic air handlers and new line sets add hours.
Heating changes the math. A gas furnace alone runs $2,650–$7,500, a 3-ton heat pump $5,150–$11,700, and replacing the AC and furnace together $6,100–$15,000. For Birmingham's climate, a heat pump or central AC is the usual fit.

The gap between an AC and a heat pump in Birmingham is about $1,850 at the typical price. That gap buys heating as well as cooling, so it matters most when the furnace is near the end of its life.
What moves an HVAC quote in Birmingham:
- Size: a 2-ton system runs about $4,750 and a 5-ton about $7,950 at the typical price. Ask for a Manual J load calculation.
- Efficiency: the minimum here is 14.3 SEER2; a 17+ SEER2 two-stage unit adds about $1,900.
- Access: attic air handlers, rooftop condensers and tight closets add labor, most often in Downtown & Avondale.
- Line set and coil: a new line set runs $180–$600, and the indoor coil has to match the new refrigerant.
- Season: spring and fall bring the best prices; a breakdown during a summer heat wave brings the worst.
Ask every Birmingham contractor for the same things: tonnage, SEER2 rating, model numbers for both the outdoor and indoor units, and whether the permit and line set are included. Compare those, not just the total. Get a quote for your heating and cooling work →
HVAC cost in Birmingham by home size
About $5,100 for a 2.5-ton AC (1,000–1,600 sq ft), $5,650 for 3 tons (1,600–2,000 sq ft), and $6,950–$7,950 for 4–5 tons in homes over 2,500 sq ft, typical Birmingham prices on existing ducts.
Worked example: a 2,000 sq ft Birmingham home with a 16-year-old AC and furnace. Replacing both runs about $9,200; switching to a 3-ton heat pump on the same ducts runs about $7,500; replacing only the AC is $5,650 but leaves an old furnace in place.
Homes over 2,500 sq ft or with two floors often have two systems or zoning. A high-efficiency zoned heat pump runs $9,400–$19,700, and adding zoning to an existing system $1,600–$4,200.
Birmingham HVAC costs by system type
| System type | Cost | Best for |
|---|---|---|
| Central AC, 3-ton (existing ducts) | $3,650–$8,200 installed | Homes with sound ducts and a furnace or air handler to pair with |
| Ductless mini-split, single zone (9,000–18,000 BTU) | $2,050–$6,750 installed | One room, an addition, or a home with no ducts |
| Multi-zone ductless mini-split (2–4 zones) | $4,200–$16,900 installed | Whole homes with no ducts, room-by-room control |
| Heat pump, 3-ton ducted (heats and cools) | $5,150–$11,700 installed | Mild and hot climates; replacing an AC and electric heat |
| Gas furnace + AC, replaced together | $6,100–$15,000 installed | Cold climates with natural gas and old equipment on both sides |
| Gas furnace only (80–96% AFUE) | $2,650–$7,500 installed | When the AC is newer than the furnace |
| Dual-fuel: heat pump + gas furnace | $6,650–$15,950 installed | Cold climates: electric heat most days, gas on the coldest |
| Cold-climate heat pump, 3-ton ducted | $8,900–$22,500 installed | Northern homes leaving gas, oil or propane |
| Central heat pump, high-efficiency with zoning | $9,400–$19,700 installed | Big or two-story homes with hot and cold rooms |
| Evaporative (swamp) cooler, roof-mounted | $1,200–$3,400 installed | Dry Western climates only |
| Geothermal heat pump (ground loop) | $14,050–$32,850 installed | Large lots and long stays in one home |
| Window or through-the-wall AC | $190–$1,100 installed | Single rooms and renters; cheapest way to cool |
Equipment vs installation: the Birmingham AC bill
On a typical $5,650 3-ton swap in Birmingham, the condenser and matched coil are roughly $2,250–$3,400 and the rest is labor, materials, the permit and overhead. Labor usually makes up 40–60% of an AC replacement.
Buying the unit yourself rarely saves much: many contractors won't install customer-supplied equipment, and the ones who do charge $460–$1,800 or more for a mini-split and won't cover the parts. Brand warranties often require a licensed installer.
What's included in a Birmingham AC replacement (and what costs extra)
A standard replacement quote covers the outdoor unit, a matched indoor coil, refrigerant, connection to your existing ducts and wiring, removal of the old unit, and startup. Common extras:
- Permit and inspection: $90–$230, often built into the quote
- New refrigerant line set: $180–$600 if the old one can't be reused
- New condenser pad: $35–$230
- Electrical panel upgrade: $780–$3,700, mostly when adding a heat pump or more capacity
Ask for the AHRI certificate showing the matched rating of your outdoor and indoor units. It proves the system you paid for is the one that was installed.
Climate and what it means here
Birmingham's long, humid summers make cooling the main load, and heat pumps suit the mild winters. Under the federal Southeast standard, a new split central AC under 45,000 BTU must be at least 14.3 SEER2.
System size
Each ton adds equipment cost: about $4,750 for 2 tons and $6,950 for 4 tons at the typical Birmingham price. A Manual J load calculation often shows a smaller system will do.
Efficiency rating
The federal minimum for a new split AC here is 14.3 SEER2 for units under about 3.75 tons, and 13.8 SEER2 for bigger units. Higher ratings cost more upfront and pay back fastest where AC runs most of the year.
New refrigerants
New systems use A2L refrigerants (R-454B or R-32), so the indoor coil must match the outdoor unit. That's why condenser-only swaps are rare now, and why older R-410A systems cost more to service.
Ducts and access
Leaky or undersized ducts, attic air handlers and rooftop condensers add hours. Whole-house duct replacement runs $2,300–$8,850.
Location: Downtown & Avondale vs North Birmingham & Eastlake
Downtown & Avondale jobs cost more because of access, parking and older buildings. North Birmingham & Eastlake quotes usually sit at or a little under the city typical.
Season and urgency
Replacing on your schedule in spring or fall is cheaper than an emergency swap in a heat wave. After-hours repair labor runs $150–$230 an hour.
- Get three quotes for the same system.Same tonnage, same SEER2 rating, model numbers on every quote. Birmingham quotes for the same 3-ton swap run anywhere from $3,650 to $8,200.
- Replace before it fails.If your system is 12–15+ years old, replace it in spring or fall. Emergency replacements in peak season leave no room to shop around.
- Right-size the system.Ask for a Manual J load calculation. An oversized AC costs more, cycles on and off, and leaves the house clammy.
- Check your utility for rebates.There is no federal tax credit for systems installed in 2026, but many utilities still pay rebates on efficient heat pumps and AC. Check before you sign; most require pre-approval or a listed contractor.
- Do the AC and furnace together if both are old.One install of both runs $6,100–$15,000, less than two separate jobs.
- Keep up with tune-ups.A yearly tune-up at $70–$180 catches weak capacitors and low refrigerant before they kill a compressor ($1,200–$2,800).
Before you pay a deposit to a Birmingham HVAC contractor, get these in writing:
- Tonnage and how it was sized (a Manual J load calculation)
- Model numbers for the outdoor unit and the indoor coil or air handler
- The matched SEER2 (and HSPF2 for a heat pump) rating
- Whether the line set is new, flushed or reused
- Permit, inspection and removal of the old unit
- Thermostat, pad, disconnect and any electrical work
- Parts and labor warranty terms, and who registers the equipment
- Total price, deposit, and start and finish dates
