Central AC installation by home size: Mount Pleasant vs Pittsburgh
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 | Mount Pleasant | Pittsburgh |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,050–$8,800 | $4,300–$7,550 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,400 | $4,800–$8,900 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,050 | $5,250–$10,250 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,200 | $6,600–$12,100 |
| 3,000+ sq ft (≈5 tons) | $9,350–$17,400 | $8,000–$14,850 |

How much should you really budget for HVAC in 2026?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
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
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
The budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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.
