Augusta's price band
Augusta is cheaper than 81% of the 195 US metros we price for HVAC work.
Most Augusta AC replacements land between $3,450 and $7,800, with $5,350 the typical price for a 3-ton system on existing ducts. Doing the furnace at the same time brings it to $5,900–$14,450, and a heat pump instead of an AC is $4,950–$11,300.
Cooling is the big job in Augusta: summers are long and humid, and winters are mild enough for a heat pump in most homes. 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–$220), a new line set ($180–$570) or duct repairs may be extra, so ask. Labor is usually 40–60% of the bill.

Figures are for the Augusta metro area in November 2026. Rural edges may add trip fees; Downtown & Harrisburg sits at the top of these ranges.
HVAC prices across Augusta
Same city, four kinds of job. Older buildings in Downtown & Harrisburg take longer, bigger homes in West Augusta & Martinez need bigger systems, and North Augusta & Aiken SC usually comes in at or under the city typical.
Downtown & Harrisburg
- Installed
- $3,600–$8,600 installed
- Typical job
- $5,050–$6,750 / 3-ton AC swap
Older homes and mid-rise buildings. A like-for-like condenser swap is routine, but rooftop units and long line runs push quotes toward the top of the range.
South Augusta
- Installed
- $3,500–$8,200 installed
- Typical job
- $4,900–$6,450 / 3-ton AC swap
A mix of renovated older homes and newer builds. Ductless mini-splits are common where old houses never had ducts.
West Augusta & Martinez
- Installed
- $3,450–$8,250 installed
- Typical job
- $4,800–$6,500 / 3-ton AC swap
Newer two-story homes are common here, which often means two systems or zoning. Access is easy, so labor per ton is lower.
North Augusta & Aiken SC
- Installed
- $3,300–$7,800 installed
- Typical job
- $4,550–$6,150 / 3-ton AC swap
Lower overhead and plenty of contractors competing for work, so quotes often come in a little under the city average. The furthest addresses may see a trip fee.
Real-world HVAC costs in Augusta
Here's what common HVAC jobs cost in Augusta 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 Augusta jobs land near $5,350; a 17+ SEER2 unit adds about $1,800.
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 $8,850.
Switch from AC + furnace to a heat pump
A 3-ton heat pump on existing ducts, typically $7,250. Keeping the furnace as backup (dual-fuel) runs $6,400–$15,350.
Cool one room with a mini-split
A 12,000 BTU single-zone mini-split for a bedroom, office or addition, typically $3,550. A 9,000 BTU unit for a small room is $2,000–$4,350.
Cool a whole home with no ducts
A 4-zone ductless system, typically $10,850. Adding ducts for central AC instead costs $2,250–$8,450 before the equipment.
How much does HVAC cost in Augusta?
A typical 3-ton replacement in Augusta is $5,350, inside a normal range of $3,450–$7,800. That price is about 14% below the US typical of $6,200. Most of the difference between quotes is efficiency, brand and how hard the old equipment is to reach.
If the furnace is old too, doing both at once ($5,900–$14,450) usually costs less than two separate jobs. A 3-ton heat pump that heats and cools runs $4,950–$11,300, and a high-efficiency zoned heat pump $9,050–$19,000.
Central AC, heat pump and furnace prices in Augusta (2026)
A 3-ton central AC runs $3,450–$7,800, a 3-ton heat pump $4,950–$11,300, and a gas furnace $2,550–$7,250, all installed.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| Central AC replacement, 3-ton (existing ducts) | $3,450 | $5,350 | $7,800 |
| Heat pump, 3-ton (existing ducts) | $4,950 | $7,250 | $11,300 |
| Gas furnace (80–96% AFUE) | $2,550 | $4,150 | $7,250 |
| Central AC + gas furnace together | $5,900 | $8,850 | $14,450 |

| Mini-split, 4 zones | $7,250 | $10,850 | $16,250 |
| Ductwork replacement, whole house | $2,250 | $4,900 | $8,450 |
AC or heat pump in Augusta? A heat pump costs about $1,900 more than a 3-ton AC at the typical price, but it also replaces your heating. If your furnace is old, compare a heat pump with the $8,850 AC + furnace swap, not with the AC alone.
What moves an HVAC quote in Augusta:
- Size: a 2-ton system runs about $4,500 and a 5-ton about $7,500 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 $1,800.
- Access: attic air handlers, rooftop condensers and tight closets add labor, most often in Downtown & Harrisburg.
- Line set and coil: a new line set runs $180–$570, 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 Augusta 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 Augusta by home size
About $4,850 for a 2.5-ton AC (1,000–1,600 sq ft), $5,350 for 3 tons (1,600–2,000 sq ft), and $6,600–$7,500 for 4–5 tons in homes over 2,500 sq ft, typical Augusta prices on existing ducts.
Worked example: a 2,000 sq ft Augusta home with a 16-year-old AC and furnace. Replacing both runs about $8,850; switching to a 3-ton heat pump on the same ducts runs about $7,250; replacing only the AC is $5,350 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 $9,050–$19,000, and adding zoning to an existing system $1,550–$4,050.
Augusta HVAC costs by system type
| System type | Cost | Best for |
|---|---|---|
| Central AC, 3-ton (existing ducts) | $3,450–$7,800 installed | Homes with sound ducts and a furnace or air handler to pair with |
| Ductless mini-split, single zone (9,000–18,000 BTU) | $2,000–$6,500 installed | One room, an addition, or a home with no ducts |
| Multi-zone ductless mini-split (2–4 zones) | $4,050–$16,250 installed | Whole homes with no ducts, room-by-room control |
| Heat pump, 3-ton ducted (heats and cools) | $4,950–$11,300 installed | Mild and hot climates; replacing an AC and electric heat |
| Gas furnace + AC, replaced together | $5,900–$14,450 installed | Cold climates with natural gas and old equipment on both sides |
| Gas furnace only (80–96% AFUE) | $2,550–$7,250 installed | When the AC is newer than the furnace |
| Dual-fuel: heat pump + gas furnace | $6,400–$15,350 installed | Cold climates: electric heat most days, gas on the coldest |
| Cold-climate heat pump, 3-ton ducted | $8,600–$21,700 installed | Northern homes leaving gas, oil or propane |
| Central heat pump, high-efficiency with zoning | $9,050–$19,000 installed | Big or two-story homes with hot and cold rooms |
| Evaporative (swamp) cooler, roof-mounted | $1,200–$3,250 installed | Dry Western climates only |
| Geothermal heat pump (ground loop) | $13,550–$31,650 installed | Large lots and long stays in one home |
| Window or through-the-wall AC | $180–$1,050 installed | Single rooms and renters; cheapest way to cool |
Equipment vs installation: the Augusta AC bill
On a typical $5,350 3-ton swap in Augusta, the condenser and matched coil are roughly $2,150–$3,200 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 $430–$1,750 or more for a mini-split and won't cover the parts. Brand warranties often require a licensed installer.
What's included in an Augusta 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–$220, often built into the quote
- New refrigerant line set: $180–$570 if the old one can't be reused
- New condenser pad: $35–$220
- Electrical panel upgrade: $750–$3,500, 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.
Augusta's climate
Cooling is the big job in Augusta: summers are long and humid, and winters are mild enough for a heat pump in most homes. 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 $4,500 for 2 tons and $6,600 for 4 tons at the typical Augusta 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 $2,250–$8,450.
Location: Downtown & Harrisburg vs North Augusta & Aiken SC
Downtown & Harrisburg jobs cost more because of access, parking and older buildings. North Augusta & Aiken SC 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 $140–$220 an hour.
- Get three quotes for the same system.Same tonnage, same SEER2 rating, model numbers on every quote. Augusta quotes for the same 3-ton swap run anywhere from $3,450 to $7,800.
- 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 $5,900–$14,450, less than two separate jobs.
- Keep up with tune-ups.A yearly tune-up at $65–$170 catches weak capacitors and low refrigerant before they kill a compressor ($1,200–$2,700).
Before you pay a deposit to an Augusta 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
