Is the price difference a dealbreaker?
At 3%, this gap is small enough that it's usually swallowed by normal quote-to-quote variation for central AC installation — focus on the contractor, not the city.

Central AC installation by home size: Auburn vs Huntsville
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 | Auburn | Huntsville |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,700–$8,200 | $4,850–$8,500 |
| 1,500 sq ft (≈2.5 tons) | $5,200–$9,700 | $5,350–$10,050 |
| 2,000 sq ft (≈3 tons) | $5,700–$11,200 | $5,900–$11,600 |
| 2,500 sq ft (≈4 tons) | $7,200–$13,250 | $7,450–$13,650 |
| 3,000+ sq ft (≈5 tons) | $8,700–$16,250 | $9,000–$16,750 |

How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
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.
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.
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.
