The short answer
For a typical residential AC or heat pump replacement in Baldwin County, expect $7,500 to $14,000 fully installed — assuming a like-for-like tonnage swap with standard-tier equipment, no major ductwork modifications, and no electrical service upgrades. Coastal-grade equipment, larger systems, variable-speed compressors, ductwork repair, and electrical work can push the number higher; entry-level builder-grade equipment in a clean swap can come in lower.
The ranges below are real installed prices we see in Baldwin County in 2026. Your actual quote depends on the home's measured load, the existing infrastructure (ductwork condition, electrical service, line-set integrity), and the equipment tier you choose.
Installed price ranges by system type
| System | Standard tier | High-efficiency tier |
|---|---|---|
| Heat pump (most common in Baldwin County) | $7,500 – $11,000 | $11,000 – $16,000 |
| Central AC + existing furnace | $5,500 – $9,000 | $9,000 – $13,000 |
| Central AC + new gas furnace | $9,500 – $13,500 | $13,500 – $18,500 |
| Single-zone mini-split | $3,500 – $6,500 | $6,500 – $9,500 |
| Multi-zone mini-split (3+ heads) | $9,000 – $15,000 | $15,000 – $25,000+ |
| Coastal-grade upcharge (per outdoor unit) | +$600 – $1,200 | +$800 – $1,500 |
Standard tier = 14-16 SEER2 / 7.5-8.0 HSPF2. High-efficiency tier = 17-20+ SEER2 / 8.5+ HSPF2 with variable-speed compressor. All ranges include equipment, install labor, standard line-set, refrigerant, basic permitting, startup commissioning, and equipment registration.
What's actually in the installed price
- AHRI-matched indoor and outdoor equipment (matched coil + condenser pair required for warranty validity)
- Manual J load calculation to right-size equipment to the actual home
- Removal and disposal of the old equipment
- Line-set flush or replacement when the existing line-set is contaminated or wrong size for the new equipment
- Refrigerant charge (R-410A on existing-stock equipment, R-32 on 2025+ inventory), nitrogen-purged braze joints, deep vacuum and weighed-in charge
- Pad or stand work, plus condensate drain routing
- Permits and inspection fees where required by Baldwin County or municipality
- Startup commissioning with documented temperature split, static pressure, and refrigerant pressures
- Manufacturer equipment registration (filed for you — needed for full warranty validity)
- Workmanship warranty on the install
What can push the price higher
Honest disclosure: most ACExperts quotes land in the standard ranges above. But the following situations push toward the high end or beyond, and they show up most often in homes that haven't had HVAC work done in 15+ years.
- Ductwork repair or replacement. Sealed, insulated, properly-sized ductwork is the difference between a system that hits its rated efficiency and one that loses 20-30% of its airflow into the attic. Adds $1,500-$5,000 depending on scope.
- Electrical service upgrade. Older homes with 100-amp service may need a panel upgrade or a dedicated subpanel for higher-efficiency variable-speed equipment. Adds $1,500-$3,500.
- Line-set replacement. When the existing refrigerant lines have been contaminated by a burnout, are improperly sized for new equipment, or run through a difficult crawlspace path, full replacement adds $400-$1,200.
- R-22 refrigerant disposal. Replacing an R-22 system requires EPA-certified refrigerant recovery with documented disposal. Adds $200-$500.
- Zoning systems. Adding multiple thermostat zones with motorized dampers and a zoning controller adds $1,500-$4,000 depending on the number of zones and ductwork access.
- Whole-house dehumidifier. A separate ducted dehumidifier for tight new-construction homes or vacation rentals adds $2,000-$3,500 installed.
Incentives that lower the cash cost
- Federal 25C tax credit. Up to $2,000 on qualifying high-efficiency heat pump installations meeting specific SEER2/HSPF2/EER2 thresholds. Standard central AC replacements qualify for a separate, smaller credit (up to $600). Non-refundable; claimed on your federal return.
- Alabama Power heat pump rebate. $200-$500 depending on equipment efficiency tier and program year, applicable when replacing electric resistance heat. Filed by ACExperts at install.
- HVAC financing. Monthly payment plans through HVAC lender partners — 0% promotional rates for 12-18 months on approved credit, or fixed APR for 7-10 year terms. Stacks with both incentives above.
- Manufacturer rebates. Brand-specific seasonal promotions vary throughout the year. We tell you about them at the in-home consultation if any apply to the equipment we're recommending.
When repair still beats replacement
Replacement is the right call when the math works. It isn't always the right call. We recommend repair when the system is under 10 years old, the repair cost is under 30% of replacement, the system runs current refrigerant (R-410A or R-32), and the repair history has been clean.
We recommend replacement when the system is past year 12, uses R-22, has had multiple major repairs in the last three years, or faces a compressor or evaporator coil failure where the repair cost approaches half of replacement.

FAQs
- Why does AC replacement cost vary so much in Baldwin County?
- The biggest drivers are tonnage (system size), efficiency tier (SEER2 rating), and what's needed beyond the bare equipment swap — ductwork modifications, electrical upgrades, line-set replacement, and pad or stand work. A simple same-tonnage like-for-like swap is the cheapest case; an upsize with new ductwork and electrical service upgrade is the most expensive.
- Should I size up when I replace my AC?
- Almost never in Baldwin County. Most existing residential systems are oversized — they cool the air quickly but don't run long enough to remove humidity, leaving the house clammy. A right-sized replacement based on Manual J load calculation typically lands at the same tonnage or smaller, and runs longer cycles that actually dehumidify. Sizing up usually makes summer comfort worse, not better.
- What's the federal 25C tax credit worth on AC replacement?
- Up to $2,000 per year on qualifying high-efficiency heat pump installations meeting specific SEER2/HSPF2/EER2 thresholds. Standard SEER2 air conditioners (cooling-only) qualify for a separate, smaller central AC credit (up to $600). The credit applies to equipment AND installation cost, is non-refundable, and is claimed on your federal return for the year of installation. ACExperts provides the AHRI certification and equipment specs at install for your tax preparer.
- Does Alabama Power offer rebates on AC replacement?
- Alabama Power's residential heat pump rebate program offers $200-$500 (depending on equipment efficiency tier and program year) for installations replacing electric resistance heating. Rebates can stack with the federal 25C credit and HVAC financing on the same install. The rebate paperwork is contractor-filed at install time.
- Can I finance AC replacement?
- Yes. ACExperts works with HVAC financing partners that offer monthly payment plans on qualifying installations. Common terms are 0% promotional rates for 12-18 months on approved credit, or fixed APR for 7-10 year terms. Financing stacks with the federal 25C credit and any applicable Alabama Power rebates. Application is online and takes minutes.
- How long does AC replacement take?
- Most residential AC or heat pump replacements complete in one full day — 6-8 hours from arrival to commissioning. Installations involving new ductwork, electrical service upgrades, line-set replacement through a difficult crawlspace, or zoned setups can stretch into a second day. ACExperts confirms the timeline in writing before starting work.
- When does repair beat replacement?
- Generally when (1) the system is under 10 years old, (2) the repair cost is less than 30% of replacement, (3) the system uses current refrigerant (R-410A or R-32, not R-22), and (4) repair history has been clean. Replace when any two of those flip — especially compressor or evaporator coil failures on systems past year 12. Use our Repair-vs-Replace Calculator at /tools/roi-calculator/ for the actual math on your specific numbers.
- What about coastal-grade equipment for homes near the bay?
- For homes within a few miles of Mobile Bay or the Gulf, coastal-grade outdoor units (treated coils, marine-grade fasteners, sealed control compartments) add roughly 10-15% to equipment cost — and add 4-7 years of service life in salt-air conditions. We recommend coastal-grade for any home in Daphne's Lake Forest or Bayfront, Fairhope's Fruit & Nut District or Point Clear, and all of Gulf Shores, Orange Beach, Fort Morgan, and Lillian.
