Home Energy guides

Heat pumps, generators, electrical panels, and electrification payback for your home.

Turn watts and hours into dollars — estimate your bill, then cut it where it actually counts.

Runtime depends on tank size, load, and fuel type — here's how to estimate hours and fuel cost.

What 100A and 200A panels really support, and how a NEC load calculation decides whether you need to upgrade.

Ductwork or no ductwork — the one question that decides between a mini-split and a central heat pump for your home.

Natural gas, propane, gasoline, or diesel — how the four generator fuels compare on cost, storage, runtime, and which fits portable vs standby use.

Why a heat pump can cut electric heating energy by half or more, and how to estimate the dollar savings for your own home.

A rough BTU-per-square-foot starting point, why both oversizing and undersizing backfire, and the Manual J load calc that gives the real number.

Why a heat pump can cut electric heating costs by half or more — and the cases where resistance heat still wins.

Match heat pump type, size, and efficiency ratings to your home — instead of buying off a spec sheet.

Add up running watts, account for the biggest motor's surge, then pick a kW that fits — not the spec-sheet number.

Portable vs standby generators — cost, fuel, automatic start, and which one actually fits your home.
