HVAC pricesin Seneca
Typical heating and air prices around Seneca and the Upstate, from a $75–$150 service call to a new system. Ranges, not quotes.
Repairs
Repairs are priced on top of the diagnostic visit. Parts and labor, typical Upstate ranges.
| 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. |
| Evening or weekend diagnostic | $150–$300 | In place of the daytime fee, when the contractor takes after-hours calls. Labor costs more too. |
| Capacitor or contactor | $150–$400 | The commonest summer repair. A dual-run capacitor costs more than a single one. |
| Clogged condensate drain | $100–$250 | Clearing the line and resetting the float switch. A failed condensate pump adds the part. |
| Thermostat | $150–$350 | A standard model, installed. A smart thermostat runs $250–$550. |
| Outdoor fan motor | $350–$850 | Motor size and whether the fan blade goes too. |
| Indoor blower motor | $450–$1,000 | A standard motor. A variable-speed (ECM) motor runs $900–$2,000. |
| Heat pump defrost board | $250–$650 | A common winter fault: the outdoor coil ices and the heat fades. |
| Furnace igniter | $150–$400 | Gas furnaces. A dirty flame sensor costs $90–$300 to clean or replace. |
| Refrigerant leak repair | $300–$1,500 | Finding and fixing the leak, before refrigerant. R-410A runs $60–$110 a lb installed. |
| Refrigerant top-up | $200–$650 | A typical 2 to 4 lb of R-410A with labor. A system that needs it every year has a leak. |
| Heat pump reversing valve | $900–$2,200 | The refrigerant is recovered, the valve brazed in, and the system recharged. |
| Indoor (evaporator) coil | $1,200–$3,000 | Out of warranty. Under the parts warranty you pay labor and refrigerant. |
| Compressor | $1,500–$3,500 | Out of warranty. On a system over 10 years old, price a replacement first. |
Tune-ups and ducts
Maintenance and ductwork. Access to the attic or crawlspace moves these more than the size of the house.
| Job | Typical price | What moves it |
|---|---|---|
| Tune-up, one system | $90–$200 | Spring for cooling, fall for heating. Cleaning the outdoor coil and checking the charge matter most. |
| Maintenance plan, a year | $150–$350 | Usually two visits plus a repair discount or priority booking. Terms vary by contractor. |
| Duct cleaning | $300–$700 | Worth it after mold, pests or a renovation. The EPA does not recommend it as routine. |
| Duct sealing and repairs | $500–$2,500 | Crawlspace and attic access set the price more than the size of the house. |
| Replace some duct runs | $1,500–$5,000 | Crushed, wet or disconnected runs replaced; the rest sealed. |
| New duct system, 1,600 sq ft | $4,000–$10,000 | About $2.50–$6.25 per square foot of house. |
New systems
Installed, at standard efficiency unless noted, with the permit, removal of the old equipment and a basic thermostat. New ductwork is extra.
| Job | Typical price | What moves it |
|---|---|---|
| Heat pump, 2 tons | $6,700–$10,500 | Smaller homes, condos and additions. With a new air handler, standard efficiency. |
| Heat pump, 3 tons | $7,500–$12,000 | The commonest replacement in the area. With a new air handler, standard efficiency. |
| Heat pump, 4 tons | $8,300–$13,500 | Larger single-system homes, often lake houses. |
| Heat pump, 3 tons, variable speed | $9,700–$18,600 | 18+ SEER2: quieter, steadier, drier air in July, lower bills. |
| AC and gas furnace, 3 tons | $8,500–$13,500 | Where the house has natural gas or propane. |
| Central AC only, 3 tons | $5,300–$8,800 | Keeps a furnace that still has years left in it. |
| Dual fuel, 3 tons | $9,500–$15,000 | A heat pump with a gas furnace that takes over on the coldest mornings. |
| Packaged unit, 3 tons | $6,000–$10,000 | Everything in one outdoor box, ducted through the wall or floor. |
| Manufactured home, 3 tons | $4,500–$8,000 | HUD-rated equipment only. Packaged or split, under the floor ducts. |
| Mini-split, one room | $3,000–$6,000 | One outdoor unit, one wall head. Line-set length and the electrical work move it. |
| Mini-split, three rooms | $7,000–$12,500 | A multi-zone outdoor unit and three heads. |
About these prices
How much is an HVAC service call in Seneca, SC?
A diagnostic visit usually runs $75–$150 during business hours. It covers the trip and finding the fault; the repair itself is priced on top once the technician knows what failed.
What is the most common AC repair in the Upstate?
A failed capacitor or contactor, especially in the first hot weeks of summer. Replaced, it typically costs $150–$400 including the part and labor.
Why is there a range instead of a price?
Because the price depends on things no website can see: the make and age of the equipment, the refrigerant it uses, access in the attic or crawlspace, and the part that failed. The contractor gives a written price after looking.
When is a repair not worth it?
When a big repair such as a compressor ($1,500–$3,500) or an indoor coil ($1,200–$3,000) lands on a system over 10 to 12 years old, price a replacement before you pay for it.
