Central AC installation by home size: Manchester vs Nashua
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 | Manchester | Nashua |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,750–$8,200 | $4,750–$8,200 |
| 1,500 sq ft (≈2.5 tons) | $5,250–$9,700 | $5,250–$9,700 |
| 2,000 sq ft (≈3 tons) | $5,750–$11,200 | $5,750–$11,200 |
| 2,500 sq ft (≈4 tons) | $7,200–$13,200 | $7,200–$13,200 |
| 3,000+ sq ft (≈5 tons) | $8,700–$16,200 | $8,700–$16,200 |

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 longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, 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.
The brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
