Is the price difference a dealbreaker?
A 13% gap is meaningful on a project this size — about $800. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Boston.
Furnace replacement by type: Amherst vs Boston
We localize each furnace replacement type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.

Furnace replacement by home size: Amherst vs Boston
Furnace cost scales with the heating capacity (BTU) your home needs — roughly 40–45 BTU per square foot in a mixed climate. Larger homes need a bigger unit and more ductwork.
| Size | Amherst | Boston |
|---|---|---|
| 1,000 sq ft (≈45,000 BTU) | $3,250–$5,850 | $3,700–$6,650 |
| 1,500 sq ft (≈68,000 BTU) | $3,800–$6,750 | $4,300–$7,650 |
| 2,000 sq ft (≈90,000 BTU) | $4,350–$7,850 | $4,950–$8,850 |
| 2,500 sq ft (≈110,000 BTU) | $5,000–$8,900 | $5,650–$10,100 |
| 3,000 sq ft (≈130,000 BTU) | $5,650–$10,000 | $6,400–$11,350 |
| 3,500+ sq ft (≈150,000 BTU) | $6,300–$11,100 | $7,150–$12,550 |

Cheapest time for furnace replacement in either city
Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
How much should you really budget for HVAC in 2026?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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 efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
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.
Climate decides the efficiency tier; a proper load calculation decides everything else. Nail both, stack the rebates you can, and you've sidestepped the two mistakes — wrong size, rushed install — that actually inflate the lifetime cost.
