How House Works

How the systems in your house work — sized for your home, your state and your model.

• Water heaters — tank, tankless, heat pump
• Heating & cooling — AC, furnaces, heat pumps, mini-splits
• Backup power & electrical — generators, transfer switches, panels, EV chargers

Calculators built on public data, error codes checked against manufacturer manuals, and diagrams that show how it all works. No lead forms.
