# HeatPumps.wiki > A U.S. homeowner reference for understanding heat pumps, comparing equipment and project choices, and checking the evidence behind costs, performance, and incentives. Guides distinguish government and standards information, manufacturer specifications, attributed cost datasets, and editorial interpretation. Page review or update dates describe the content review; they do not guarantee that a price, product, or incentive remains current. Official sources and project-specific details still matter. The three calculators run locally in the browser and state their inputs and assumptions. Incentive guides link to official programs; verify availability and eligibility with the program administrator. Project guidance links to editorial checklists and cost information. ## Publication and evidence - [Official Information About HeatPumps.wiki](https://heatpumps.wiki/ai-info/): Publisher information for HeatPumps.wiki: residential U.S. scope, source attribution, AI-assisted research, calculator assumptions and current contact availability. - [About HeatPumps.wiki](https://heatpumps.wiki/about/): Learn what HeatPumps.wiki covers, how we approach heat-pump research and what readers should expect from our buying, cost and troubleshooting content. - [Editorial Policy](https://heatpumps.wiki/editorial-policy/): Read HeatPumps.wiki's sourcing, corrections, AI-assisted production, review and commercial-disclosure standards. - [Research & Comparison Methodology](https://heatpumps.wiki/methodology/): See how HeatPumps.wiki evaluates heat-pump equipment, prices, efficiency, cold-climate performance, rebates and comparison questions. ## Topic starting points - [Types of Heat Pumps](https://heatpumps.wiki/types/): Compare air-source, ducted, ductless, cold-climate, geothermal and dual-fuel heat pumps to find the right system for your home and climate. - [Heat Pump Brands](https://heatpumps.wiki/brands/): Compare major heat pump brands including Mitsubishi, Bosch, Carrier, Daikin and Trane by system type, efficiency, cold-climate capability and ideal use case. - [Heat Pump Comparisons](https://heatpumps.wiki/compare/): Compare heat pumps with furnaces, air conditioners, mini-splits, geothermal systems and propane heating to find the right setup for your home. - [Heat Pump Sizing](https://heatpumps.wiki/sizing/): Learn how heat pumps are sized using heating and cooling loads, BTU/h, tonnage and Manual J - and why square footage alone is not enough. - [Heat Pump Efficiency](https://heatpumps.wiki/efficiency/): Understand heat pump efficiency using SEER2, HSPF2, EER2 and COP, including cold-weather performance and electricity consumption. - [Heat Pumps by Climate](https://heatpumps.wiki/climate/): Learn how heat pump selection changes by climate, from cold and freezing winters to hot-humid and cooling-dominated regions. - [Heat Pump Maintenance](https://heatpumps.wiki/maintenance/): Use this heat pump maintenance checklist for filters, outdoor-unit care, professional service, winter checks and signs your system needs repair. - [Heat Pump Installation Cost in 2026](https://heatpumps.wiki/cost/installation-cost/): Heat pump installation averages about $15,393 in 2026 marketplace data.
