Two hard seasons

Morning mist over Lake Keowee, with docks along a wooded shore — Lake Keowee, a few miles north of Seneca.

91°

The average July high at Clemson, next door to Seneca, with about 55 days a year at 90°F or more and wet air off two big lakes.

32°

The average January low. Mild for a furnace, but on frosty mornings a heat pump stops to defrost and leans on its backup heat.

What things cost here

Typical installed prices in Seneca and the Upstate, as ranges. A ballpark, not a quote: the contractor prices your job after seeing it.

Job	Typical price	What moves it
Diagnostic visit	$75–$150	The minimum for any repair call: the trip and finding the fault. Many contractors credit it toward the repair.
Capacitor or contactor	$150–$400	The commonest summer repair. A dual-run capacitor costs more than a single one.
Tune-up, one system	$90–$200	Spring for cooling, fall for heating. Cleaning the outdoor coil and checking the charge matter most.
Heat pump, 3 tons	$7,500–$12,000	The commonest replacement in the area. With a new air handler, standard efficiency.
AC and gas furnace, 3 tons	$8,500–$13,500	Where the house has natural gas or propane.
Mini-split, one room	$3,000–$6,000	One outdoor unit, one wall head. Line-set length and the electrical work move it.
Duct sealing and repairs	$500–$2,500	Crawlspace and attic access set the price more than the size of the house.

Questions people ask

How much does an AC repair cost in Seneca, SC?

Most repairs run $150–$850 for parts and labor, on top of a $75–$150 diagnostic visit. A failed capacitor, the commonest summer fix, is $150–$400; a compressor is $1,500–$3,500.

How much is a new heat pump in Seneca?

A 3-ton heat pump with a new air handler, the most common replacement around Seneca, typically runs $7,500–$12,000 installed at standard efficiency, and $9,700–$18,600 for a variable-speed system.

Who does the work when I contact Seneca Heat & Air?

Seneca Heat & Air is a referral service. Your request goes to a licensed local HVAC contractor, licensed by South Carolina LLR, who calls you, prices the job after seeing it and does the work under their own license and warranty.

Which towns do you cover?

Seneca, Clemson, Walhalla, Westminster, Pendleton, Central, Salem, Six Mile, West Union, Fair Play, Long Creek and Townville, and the homes around Lake Keowee and Lake Hartwell. If you are just outside that, ask: the form takes any nearby town.

How soon will someone call?

The contractor calls or texts you back after your request arrives. Phones are answered Monday to Saturday, 7am to 7pm.

Is there still a federal tax credit for heat pumps in 2026?

No. The 25C credit ended for systems placed in service after December 31, 2025. Duke Energy customers may still qualify for a $350–$900 Smart $aver rebate on a qualifying heat pump, and South Carolina's state rebates have not opened yet.

Heat pump or gas furnace in Seneca?

Heat pumps are the most common system here: winters are mild, and many homes have no gas line. Where Fort Hill natural gas or propane is already in the house, an AC with a gas furnace, or a dual-fuel heat pump, can make sense.

How often should a heat pump be serviced?

Twice a year in the Upstate: spring before the cooling season and fall before the heating season, because a heat pump works both. A tune-up typically costs $90–$200 a visit.

Is the ballpark on this site a quote?

No. It is a range from typical Upstate prices. The contractor gives you a written price after seeing the system, and you are never obliged to go ahead.
