HVAC prices across Myrtle Beach
Same city, four kinds of job. Older buildings in Downtown Myrtle Beach & the Boardwalk take longer, bigger homes in Surfside, Murrells Inlet & Georgetown need bigger systems, and Conway usually comes in at or under the city typical.
Downtown Myrtle Beach & the Boardwalk
- Installed
- $3,600–$8,600 installed
- Typical job
- $5,050–$6,750 / 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.
Conway
- Installed
- $3,300–$7,650 installed
- Typical job
- $4,600–$6,050 / 3-ton AC swap
Lots of rental housing and smaller homes. Window units and single-zone mini-splits are common, and central systems tend to be smaller.
North Myrtle Beach & Carolina Forest
- Installed
- $3,450–$7,800 installed
- Typical job
- $4,800–$6,150 / 3-ton AC swap
Established neighborhoods of single-family homes. Most jobs are a standard swap at the city's typical price.
Surfside, Murrells Inlet & Georgetown
- 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.
Real-world HVAC costs in Myrtle Beach
Here's what common HVAC jobs cost in Myrtle Beach 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 Myrtle Beach 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 Myrtle Beach?
Between $3,450 and $7,800 for a 3-ton central AC on existing ducts, and most Myrtle Beach homeowners pay close to $5,350. Size, efficiency and access set the number: a basic 14.3 SEER2 swap in an easy spot sits at the bottom, and a 20+ SEER2 variable-speed system with an attic air handler sits at the top.
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 Myrtle Beach (2026)

The gap between an AC and a heat pump in Myrtle Beach is about $1,900 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 Myrtle Beach:
- 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 Myrtle Beach & the Boardwalk.
- 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 Myrtle Beach 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 Myrtle Beach 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 Myrtle Beach prices on existing ducts.
Worked example: a 2,000 sq ft Myrtle Beach 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.
Myrtle Beach 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 Myrtle Beach AC bill
On a typical $5,350 3-ton swap in Myrtle Beach, 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 a Myrtle Beach 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.
Climate and what it means here
Myrtle Beach's long, humid cooling season is the main load. 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 Myrtle Beach 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 Myrtle Beach & the Boardwalk vs Conway
Downtown Myrtle Beach & the Boardwalk jobs cost more because of access, parking and older buildings. Conway 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. Myrtle Beach 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 a Myrtle Beach 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
