Cost overview
Boston's old housing stock (pre-1950 triple-deckers, row houses) means many installs are ductless whole-home systems. Mass Save provides up to $10,000 in whole-home heat pump rebates — the most generous program in the country. Income-qualified households can layer HEEHRA (where state funding is open) on top, often bringing net cost into the $4,000–$10,000 range. The federal §25C tax credit was repealed for installs after Dec. 31, 2025 and is not included.
Below is a typical breakdown for a whole-home replacement. Your actual quote will vary based on home size, ductwork condition, electrical panel capacity, and which contractor you choose. We recommend getting at least three quotes — pricing variance between installers in Bostonis often 20–30% for an identical system.
What you're actually paying for
| Component | What's included | Low | High |
|---|---|---|---|
| Equipment | Outdoor unit, indoor air handler, refrigerant line set | $5,040 | $9,030 |
| Labor | Boston HVAC labor at ~$115/hr, 16–28 hr install | $1,840 | $3,220 |
| Ductwork | Modifications, sealing, and balancing existing ducts | $800 | $2,400 |
| Electrical | Dedicated 240V circuit; panel upgrade if needed | $400 | $1,800 |
| Permits & inspection | Boston mechanical permit + inspection fees | $310 | $390 |
| Total project | $8,390 | $16,840 | |

Ducted vs. ductless vs. geothermal
| System type | Installed cost | Efficiency | Best for |
|---|---|---|---|
| Ducted central | $9,000–$16,000 | SEER2 16–20 | Homes with existing ductwork |
| Ductless mini-split | $5,000–$12,000 | SEER2 18–30 | Additions, retrofits, room-by-room control |
| Geothermal | $22,000–$40,000 | COP 3.5–5.0 | Long-term owners with yard space |
For most Boston homes with existing AC ductwork, a ducted central heat pump is the fastest and cheapest path. Ductless makes sense for additions, sunrooms, or homes without ducts. Geothermal pencils out only for owners staying 15+ years.

Why Boston's climate matters
Boston sits in IECC climate zone 5A (cold-humid). That means sizing, refrigerant choice, and equipment selection should optimize for cold-climate performance below freezing. Ask installers specifically about low-ambient performance ratings (HSPF2 and capacity at 5°F).
Popular brands in this market: Mitsubishi, Fujitsu, LG, Carrier. All major brands have comparable warranty terms (10-year parts, 5-year labor when registered).
