What Is a Heat Pump and How Does It Work
A heat pump is a system that moves heat between indoors and outdoors using electricity, providing both heating and cooling. It works by circulating refrigerant through a compressor and heat exchanger to absorb or release heat, rather than generating heat directly. Modern heat pumps can operate efficiently even in cold climates, with cold-climate models designed for temperatures as low as -15°F or lower. This technology is a core part of building electrification and decarbonization strategies worldwide. ENERGY STAR certified heat pumps meet strict efficiency guidelines set by the U.S. Environmental Protection Agency.
The main types of heat pumps are air-source, ground-source (geothermal), and water-source. Air-source heat pumps are the most common for homes and businesses because they are easier and cheaper to install. Ground-source systems use stable underground temperatures for higher efficiency but require higher upfront investment. Ductless mini-split heat pumps are a popular air-source option for homes without existing ductwork.
Heat Pump Costs, Efficiency, and Savings
The average installed cost for a residential air-source heat pump in the United States ranges from about $4,000 to $12,000, depending on capacity, brand, and home size. Ground-source systems typically cost $10,000 to $30,000 installed due to drilling or trenching requirements. Heat pump efficiency is measured by the Heating Seasonal Performance Factor (HSPF) for heating and Seasonal Energy Efficiency Ratio (SEER) for cooling. Top-tier models often exceed HSPF ratings of 10 and SEER ratings of 20, meaning they deliver more than 300% efficiency compared to traditional electric resistance heating.
Homeowners can reduce heat pump costs through federal tax credits under the Inflation Reduction Act, which offers up to $2,000 for qualifying heat pump systems. Many utilities and state programs also provide rebates for high-efficiency models. Heat pumps can lower annual heating and cooling bills by 30% to 50% compared to oil or propane systems, according to the U.S. Department of Energy.

Top Heat Pump Brands and Market Trends
Leading heat pump manufacturers include Mitsubishi Electric, Daikin, Carrier, Lennox, and Bosch. These companies offer cold-climate air-source models with enhanced performance at low outdoor temperatures. Inverter-driven compressors in modern units adjust speed continuously to maintain comfort and reduce energy use. Heat pump adoption has grown rapidly as prices decline and incentives expand, with global heat pump sales rising in 2023 and 2024 across Europe, North America, and Asia.
The global heat pump market is projected to grow at a compound annual growth rate of over 6% through the next decade, driven by building decarbonization policies and rising electricity grid cleanliness. Companies like Tesla and SpaceX have explored integrated heat pump systems for their own facilities and vehicles, including the Tesla Model Y heat pump which improves electric vehicle efficiency.
