HVAC pricing is hard to pin down because every home is different. The figures below are current market ranges for the Greenville, SC area and the wider Southeast, drawn from the sources listed at the bottom of this page. They are meant to give you a realistic sense of cost before anyone visits. They are not First Class prices, and your exact quote depends on an in-home assessment.
One piece of good news for Upstate homeowners: South Carolina labor rates run below the national average, so local pricing tends to land at the friendlier end of national ranges.
What affects HVAC pricing
Six things move the number on your quote more than anything else. Understanding them helps you read any estimate, ours or a competitor's.
System size
HVAC equipment is sized in tons (cooling) and BTUs (heating). A 1,200 square foot home needs far less capacity than a 3,000 square foot home, and a bigger system costs more. Correct sizing comes from a Manual J load calculation, not a rule of thumb.
Efficiency rating
Cooling efficiency is measured in SEER2, heating in AFUE (furnaces) and HSPF2 (heat pumps). A higher rating costs more up front and uses less energy over time. New systems start at 14.3 SEER2 by federal minimum.
Labor and access
Installation labor is a large share of any quote. A tight attic, a rooftop unit, or a crawlspace takes longer than a garage install, and that time shows up in the price.
Ductwork condition
Leaky, undersized, or aging ducts can add cost to a system replacement. Sealing or modifying ductwork protects the efficiency you are paying for. Skipping it wastes the new equipment.
Permits and code
Most equipment replacements require a permit and an inspection. Permit fees vary by jurisdiction and are a normal line item, not a markup.
Refrigerant transition
The industry is phasing out R-410A refrigerant in favor of R-454B. Older systems that need an R-410A recharge are seeing higher refrigerant costs as supply tightens, which is one more reason aging equipment gets expensive to keep alive.
HVAC installation costs
A new HVAC system in the Greenville, SC area typically runs from about $5,000 to $15,000 installed, depending on the equipment type, system size, and efficiency rating. A single-component swap costs less. A full heating and cooling replacement with ductwork sits at the higher end. South Carolina labor rates run below the national average, which helps.
| Service | Typical cost | What drives the price |
|---|---|---|
| Central air conditioner (replacement) | $3,800–$7,500 | Standard to mid-efficiency. High-efficiency variable-speed units reach $12,000+. Priced by tonnage and SEER2. |
| Gas furnace (replacement) | $3,800–$10,000 | Driven by AFUE rating and BTU output. Warm-climate homes often need smaller, lower-cost units. |
| Heat pump (ducted, air-source) | $6,000–$12,000 | Premium variable-speed systems run higher. A common, efficient choice for the Upstate's mild winters. |
| Full system (heating + cooling) | $8,000–$15,000 | Matched AC and furnace, or a heat pump with air handler. Best value when both components are aging. |
| Ductless mini-split (single zone) | $2,500–$6,000 | Ideal for additions, garages, or rooms without ductwork. Multi-zone systems run $6,500 to $15,000+. |
| Ductwork (new or replacement) | $2,000–$12,000 | Roughly $10 to $25 per linear foot installed. Material and home layout set the price. |
| Air handler (replacement) | $1,500–$4,200 | Pairs with a heat pump or AC condenser. Variable-speed models cost more. |
| Smart thermostat (installed) | $200–$500 | Device plus labor. A C-wire add-on can raise the cost slightly. |

HVAC repair costs
Most air conditioning repairs in Greenville, SC fall between $150 and $1,500, with the average repair landing around $350 to $600. A worn capacitor is an inexpensive fix. A failed compressor is the costliest, and often pushes an older system toward replacement.
| Service | Typical cost | What drives the price |
|---|---|---|
| Capacitor replacement | $150–$400 | The most common AC repair. An inexpensive part with quick labor. |
| Condenser fan motor | $300–$900 | Replaces the outdoor fan that rejects heat from the system. |
| Refrigerant recharge or leak repair | $250–$1,500 | Leak detection plus refrigerant. R-410A costs are climbing as that refrigerant is phased out. |
| Evaporator coil replacement | $600–$1,500+ | Labor-intensive. On older systems, a failed coil often signals it is time to replace. |
| Compressor replacement | $800–$2,300 | The most expensive common repair, up to $3,500. Out of warranty, replacement is frequently the better value. |

Repair or replace?
A useful rule of thumb is to multiply your system's age in years by the repair cost. If the result is over $5,000, replacement usually makes more financial sense than the repair. Two more signs point to replacement: a unit past 10 to 15 years old, and rising energy bills from an inefficient system.
| System | Typical lifespan | Notes |
|---|---|---|
| Central air conditioner | 10–15 years | Seasonal use. Well-maintained units can reach 20 years. |
| Gas furnace | 15–20 years | The longest-lived component. A cracked heat exchanger ends it early. |
| Heat pump | 10–15 years | Runs year-round in the Upstate, so it wears faster than a furnace. |
| Tank water heater | 10–12 years | Tankless models last 15 to 20 years. |
Lean toward replacement when
- The system is more than 10 to 15 years old
- The repair cost times the age is over $5,000
- Energy bills keep climbing season after season
- A cracked heat exchanger, failed compressor, or major refrigerant leak
- The system still uses R-22 refrigerant (no longer produced)
Repair usually makes sense when
- The system is under 10 years old and still efficient
- The repair is a single affordable part
- The unit is under manufacturer warranty
- It has been well maintained and runs reliably otherwise
Rebates and incentives in 2026
Federal and local incentives can lower the real cost of a new high-efficiency system. The picture changed in 2026, so it is worth knowing what still applies before you buy.
Federal 25C tax credit
ExpiredThe federal Energy Efficient Home Improvement Credit (25C), which offered up to $2,000 on qualifying heat pumps, expired on December 31, 2025. Equipment installed in 2026 and later no longer qualifies.
Geothermal heat pump credit
30% (no cap)The federal credit for qualifying geothermal heat pump systems remains in place at 30 percent of cost with no dollar cap. It is one of the few federal HVAC incentives still available.
Duke Energy Smart $aver rebates (SC)
$200–$900Duke Energy offers South Carolina customers rebates on qualifying high-efficiency heat pumps, air conditioners, and mini-splits. Amounts depend on the equipment and your existing system.
Duke Energy conversion rebates (SC)
Up to $2,500Switching from electric strip heat to a heat pump, dual-fuel, or geothermal system can earn the largest Duke rebates, because the energy savings are the largest.
