How the math works

Premium = HP install − alternative − tax credit − rebates. Payback = premium / savings.

$14k − $9k − $2k − $2.5k = $500 premium. $2,400 × 35% = $840 savings. 0.6 yr payback.

Frequently Asked Questions

Heat pump economics?

Cold-climate heat pump install: $8,000–18,000 (whole-home), $4,500–8,500 (mini-split). Vs gas furnace replace: $4,000–8,000. Vs new AC + electric strip: $5,000–10,000. Federal credit 25C: 30% up to $2,000. State rebates: $1,000–4,000 (CA TECH, MA Mass Save, NYSERDA). Utility: $500–2,000. Energy savings: 30–60% vs gas heat in mild climates, 0–30% in cold climates depending on backup. Cooling included — replaces both furnace + AC. Mini-split for additions/conversions: cheaper, zone-specific.

How accurate is this estimate?

Material and labor estimates are accurate to ±15% with reasonable inputs but local market conditions vary. Major markets cost 30–60% more than rural. Labor rates regional (union vs non-union, prevailing wage). Material prices fluctuate with commodity cycles. Get 3 contractor bids for any work over $5k. This calculator is a sanity check, not a substitute for actual quotes.

DIY vs contractor?

DIY savings: 40–70% of contractor cost on labor. Realistic skill threshold: painting, basic plumbing, simple electrical, drywall, flooring. Pro required: structural, gas, complex electrical, HVAC, roofing (warranty + insurance), permits. Permitted work without license risks insurance and resale. Time: hobby DIYers 3–5x slower than pro. Tools and learning curve real.

Permit and code compliance?

Permits required for: structural changes, additions, electrical service changes, plumbing rough-in, HVAC replacement, roof replacement (varies), fence (varies). Cost: $50–2,000+ depending on scope. Skipping permit risks: stop work order, fines, forced removal, insurance denial, resale title issues. Always pull permit; cost is small relative to compliance friction.
