Direct Answer: $15K-$28K Gross, $0-$18K Net
For a typical 2,200 sq ft Massachusetts single-family home in 2026:
| Configuration | Gross Install | Net (Standard) | Net (Income-Eligible) |
|---|---|---|---|
| Ducted whole-home cold-climate ASHP | $18,000-$26,000 | $6,000-$14,000 | $0-$8,000 |
| Ductless 4-zone mini-split | $14,000-$22,000 | $2,000-$10,000 | $0-$4,000 |
| Ductless 6-8 zone whole-home | $22,000-$32,000 | $10,000-$20,000 | $4,000-$14,000 |
| Geothermal whole-home | $35,000-$70,000 | $14,500-$45,000 | $8,500-$39,000 |
Most MA homeowners pursuing standard cold-climate ASHP land at $18K-$22K gross / $8K-$12K net after the Mass Save $10K rebate.
What Drives the Cost
5 factors explain 90% of cost variation between similar homes:
Home Size + Heating Load (40% of cost variance)
Manual J load determines heat pump tonnage. 1,500 sq ft home: 2-3 ton system. 2,200 sq ft: 3-4 ton. 3,000+ sq ft: 4-5 ton or dual-system. Each ton adds ~$3,000-$4,000 to equipment cost.
Existing Distribution (30%)
Good ductwork in place: ducted ASHP straightforward, $18K-$22K. No ducts (radiator-heated home): ductless multi-zone required, $20K-$28K. Bad ducts requiring upsizing: +$2K-$4K.
Electrical Panel Capacity (15%)
Existing 200A panel with available slot: $0 add. Existing 100/125A panel needing upgrade: +$2,400-$4,000. Mass Save $4K panel rebate when paired with electrification typically zeros net cost.
Brand + Model Tier (10%)
Top tier (Mitsubishi Hyper-Heat, Fujitsu XLTH): $26K-$28K. Mid tier (Bosch IDS, Daikin): $20K-$24K. Budget tier (Mr. Cool, Rheem): $16K-$20K. All qualify for same $10K Mass Save rebate.
Refrigerant Line Run + Site Complexity (5%)
Outdoor unit close to indoor: low cost. Long lineset run (50+ ft) or complex routing: +$800-$2,400.
What Most Quotes Miss
5 line items often omitted from initial quotes:
- Manual J load calculation ($300-$650 if charged separately): should be FREE on Mass Save HPC quotes. Pay-extra is a red flag.
- AHRI matched-pair certification: required for Mass Save filing. Should be on the quote in writing.
- Permit fees ($240-$520): 248 CMR + 527 CMR + 780 CMR depending on scope. Not optional.
- Old equipment removal + disposal ($300-$800): old furnace, AC, oil tank.
- Refrigerant line insulation ($200-$500): code-required for refrigerant line runs.
Pro Build's standard quote includes ALL 5 line items in writing on page 1.
