About

About ElectrifyCost

ElectrifyCost is a source-backed planning tool for U.S. homeowners thinking about heat pumps, EV chargers, solar, batteries, panel upgrades, water heaters, induction ranges, insulation, and the other pieces of electrifying a home. Every cost range here is traceable to a primary source — IRS, DOE, NREL, EIA, BLS, ENERGY STAR, NEEP, ACCA — listed at /sources/ with the date each one was last reviewed.

The deliberate position is no funnel. No email gate. No phone form. No referral marketplace. Just the math and the questions to ask your contractor. The site is funded by display ads and clearly-disclosed affiliate links where they don't change the calculator output.

Who built it

Martin Lashgari, Ph.D., P.E., PMP

Founder & author

I'm a structural engineer by training — Ph.D., licensed P.E., and PMP-certified. I built ElectrifyCost after going through my own home's electrification decisions and finding that nobody was publishing the actual installed-cost math with primary sources cited. Most "cost calculators" online either gate the result behind an email form, lead you straight to a contractor referral funnel, or quote a single national average that's useless for your state and home.

My engineering background is in structural — not HVAC or electrical — so I don't pretend to be a contractor. What I am good at is reading codes (NEC, ASHRAE, IECC, ACCA Manual J), reading BLS labor data, and building defensible cost models that don't hand-wave their inputs. The same rigor a structural P.E. applies to a beam calculation is what I apply to a heat-pump installed-cost band: state the assumption, cite the source, show the math, label the uncertainty.

ElectrifyCost is not a substitute for a licensed electrician, HVAC contractor, or your local permit office. The cost ranges here are planning estimates, not bids. Always work with a licensed professional in your state for the actual installation.

How the numbers get on this site

1 Every numeric input — equipment cost, labor hours, state multiplier, climate data, rebate amount, expiration date — lives in a CSV file under data/csv/. No magic numbers hard-coded in TypeScript. Editing a row updates the calculator everywhere it's referenced.
2 Each CSV row carries a source-ID column that maps to a primary-source URL and a last_reviewed date. The site footer surfaces the most recent review date; the sources page lists all of them.
3 The calculator engine — published in plain-English form on the methodology page — applies state labor multipliers, install-difficulty bands, home-type adjustments, timing premiums, and incentive stacking on top of the base cost. Every step is auditable.
4 Sources are re-reviewed at least quarterly. Rebate programs change quickly — Mass Save reduced its heat-pump cap from $10K to $8.5K on 2026-01-01; OBBBA terminated the federal 25C credit on 2025-12-31; the federal 30C EV-charger credit ends 2026-06-30. Each change updates the source row's last_reviewed date so readers know how fresh the data is.

What this site is not

✗ A contractor bid. The ranges shown are planning estimates calibrated to public benchmarks. Your actual quotes will vary based on local market, equipment selection, install complexity, code requirements, and contractor backlog.
✗ A substitute for an NEC 220.83 load calculation. The panel-risk verdict on the calculator is a probabilistic heuristic, not a stamped engineering analysis. A licensed electrician is required before any panel upgrade or new circuit.
✗ A rebate-eligibility determination. Every state and utility program has its own income, equipment, contractor, and timing rules. The calculator surfaces what likely applies; you must verify with the linked program administrator before claiming.
✗ Tax advice. Federal credits referenced here (25C / 25D / 30C / 30D / 25E) are summarized for planning purposes and reflect current IRS guidance and the One Big Beautiful Bill Act (OBBBA, 2025). For your filing, consult a tax professional.

Editorial & correction policy

Found an error? Email hello@electrifycost.com with the page, the claim, and a primary-source URL showing the correct value. Corrections are made within 48 hours and the source row's last_reviewed date is bumped.

Affiliate links — where present — are clearly disclosed at the top of any section containing them. Affiliate revenue does not change the calculator math, the recommended equipment list, or the rebate amounts. See the methodology page for how products get on the recommended list at all.
