Central AC installation by home size: Chattanooga vs Jackson
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 | Chattanooga | Jackson |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,500–$7,850 | $4,350–$7,600 |
| 1,500 sq ft (≈2.5 tons) | $5,000–$9,300 | $4,800–$8,950 |
| 2,000 sq ft (≈3 tons) | $5,450–$10,750 | $5,250–$10,350 |
| 2,500 sq ft (≈4 tons) | $6,900–$12,650 | $6,650–$12,200 |
| 3,000+ sq ft (≈5 tons) | $8,350–$15,550 | $8,050–$14,950 |

How much should you really budget for HVAC in 2026?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
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 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 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.
