Heat Pump Calculators
Plan a heat pump with confidence: estimate the cost, size the system, project your savings versus your current heating, and find out whether a heat pump is worth it for your home and climate.
One system, all year
A heat pump heats in winter and cools in summer at 300–400% efficiency — the most efficient way to condition a home.

Decision →Why heat pumps in 2026?
A heat pump both heats and cools your home using electricity, moving heat instead of burning fuel. Because it moves rather than makes heat, a modern heat pump delivers 300–400% efficiency (a COP of 3–4) — far beyond any furnace. The federal 25C credit (30%, up to $2,000) ended for installs after December 31, 2025, so in 2026 the case rests on running costs, cold-climate models that now work well below freezing, and any state, utility or HEAR rebate you can get.
Pairing a heat pump with rooftop solar is the cleanest, cheapest way to run a home — your panels can power your heating and cooling directly. See how solar pencils out with our Solar Payback Calculator and state incentives.
