Is the price difference a dealbreaker?
A 2% difference on central AC installation is minor — you'll typically see a wider spread just from getting multiple quotes in the same city, so don't let location drive the decision.

Central AC installation by home size: Marietta vs Savannah
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 | Marietta | Savannah |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,900–$8,500 | $4,950–$8,650 |
| 1,500 sq ft (≈2.5 tons) | $5,400–$10,100 | $5,450–$10,200 |
| 2,000 sq ft (≈3 tons) | $5,950–$11,650 | $6,000–$11,800 |
| 2,500 sq ft (≈4 tons) | $7,500–$13,700 | $7,600–$13,900 |
| 3,000+ sq ft (≈5 tons) | $9,050–$16,800 | $9,150–$17,050 |

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
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
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
Skip the brand debate. A correctly sized system, an efficiency tier that fits your climate, and a properly commissioned install will save you more than any label ever could.
