About Heat Pump Atlas

Heat Pump Atlas is an independent reference for homeowners comparing heat pumps in the United States. We turn official certification data into clear, comparable pages: what each model costs to run in your state, how much heat it keeps when the weather turns cold, and which other brands sell the same equipment.

What makes this site different

  • Model-level, not generic. Every estimate is tied to a specific certified outdoor unit, not to a "typical heat pump".
  • Official data only. Performance figures come from the U.S. EPA's ENERGY STAR certified products dataset; electricity prices come from the U.S. Energy Information Administration.
  • Transparent math. Our methodology explains every formula, and every calculator lets you replace our assumptions with your own.
  • No sales. We don't sell or install equipment and we don't take payments from manufacturers to rank their products.

Who runs it

Heat Pump Atlas is published by Astexus. We are a small independent publisher. The site is funded by display advertising; advertising never influences the data, rankings or editorial content.

Data currency

The current edition covers 308 heat pump outdoor units from 31 brands, refreshed from ENERGY STAR on November 7, 2026. We refresh the dataset regularly and update electricity prices as EIA publishes them.
