Is the gap worth worrying about?
That 2% gap is small — for central AC installation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.
Central AC installation by type: Florence vs Rock Hill
Every central AC installation type gets its own localized price for each metro, using the same labor, climate and permit adjustments — a true apples-to-apples comparison.
| Type | Florence | Rock Hill |
|---|---|---|
| 2–3 ton (small home) | $5,200–$8,200 | $5,300–$8,350 |
| 3.5–4 ton (mid home) | $7,200–$11,200 | $7,350–$11,450 |

Central AC installation by home size: Florence vs Rock Hill
Central AC is sized in tons of cooling — about one ton per 500–600 sq ft. Undersizing leaves you hot; oversizing short-cycles and wastes money, so a Manual J load calculation matters.
| Size | Florence | Rock Hill |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,700–$8,200 | $4,800–$8,350 |
| 1,500 sq ft (≈2.5 tons) | $5,200–$9,700 | $5,300–$9,900 |
| 2,000 sq ft (≈3 tons) | $5,700–$11,200 | $5,800–$11,450 |
| 2,500 sq ft (≈4 tons) | $7,200–$13,250 | $7,350–$13,500 |
| 3,000+ sq ft (≈5 tons) | $8,700–$16,250 | $8,900–$16,550 |

Cheapest time for central AC installation in either city
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
How much should you really budget for HVAC in 2026?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
The longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The efficiency-first case
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
The budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
