Heat pumps have become the fastest-growing HVAC technology in the U.S., offering both heating and cooling from a single system at significantly higher efficiency than traditional furnace-and-AC combos. Air-source heat pumps are the most common and affordable option, while ground-source (geothermal) systems deliver the highest efficiency but at a much higher upfront cost. The Inflation Reduction Act provides federal tax credits of up to $2,000 for qualifying heat pump installations, making this an especially attractive time to invest in heat pump technology.
Air-source heat pumps extract heat from outdoor air (even in cold weather) and are the most commonly installed type. They look similar to a central AC condenser and use the same ductwork as a traditional forced-air system. Ground-source (geothermal) heat pumps extract heat from the earth via underground loops, delivering 300–500% efficiency. Geothermal systems cost 3–4 times more upfront but have the lowest operating costs of any HVAC technology and last 20–25 years (50+ years for the ground loop).
Heat pump capacity is measured in tons, just like air conditioners. Since a heat pump handles both heating and cooling, proper sizing is critical. An undersized unit in heating mode will rely heavily on expensive backup electric resistance heat strips, while an oversized unit will short-cycle in cooling mode and fail to dehumidify. Variable-speed (inverter-driven) heat pumps mitigate sizing concerns by adjusting output continuously to match the load.
Heat pump efficiency is measured by SEER2 for cooling and HSPF2 (Heating Seasonal Performance Factor) for heating. Higher ratings mean lower operating costs. Variable-speed (inverter) compressors achieve the highest efficiency ratings because they modulate output to precisely match the heating or cooling demand rather than cycling on and off. Cold-climate heat pumps are specifically engineered to maintain heating capacity in temperatures as low as -15°F, making them viable in northern states.
The ground loop is the largest cost component of a geothermal system. Horizontal loops are buried 4–6 feet deep in trenches and require significant yard space (about 2,500 sq ft per ton). Vertical loops use boreholes drilled 150–400 feet deep and are suitable for smaller lots but cost more per ton. Open-loop systems use well water and are the cheapest to install but require adequate water flow and local permits. The ground loop itself has a 50+ year lifespan, so the main unit can be replaced without disturbing the loop.

Air-source heat pump installation labor is comparable to central AC installation — a standard replacement takes 6–10 hours for a two-person crew. The work includes setting the outdoor unit, installing the indoor air handler or connecting to existing ductwork, running refrigerant lines, wiring the system, and programming the thermostat. Geothermal installations are far more labor-intensive due to the ground loop, requiring excavation equipment and specialized installers. A geothermal project typically takes 1–2 weeks from start to finish.
Air-source heat pump installation takes 1–2 days. Geothermal systems take 1–2 weeks including loop installation.
Yes. Modern cold-climate heat pumps are rated to maintain full heating capacity at temperatures as low as 5°F and continue operating (at reduced capacity) down to -15°F or colder. Brands like Mitsubishi Hyper-Heat, Bosch, and Daikin Aurora are specifically designed for cold climates. In extremely cold regions, a dual-fuel system (heat pump + gas furnace) provides the best combination of efficiency and performance.
Heat pumps deliver 2–4 times more heat energy per unit of electricity compared to electric resistance heating. Compared to a gas furnace, savings depend on local gas vs. electricity prices, but most homeowners save 20–40% on combined heating and cooling costs by switching to a high-efficiency heat pump.
The Inflation Reduction Act provides a federal tax credit of up to $2,000 for qualifying heat pump installations through 2032. Income-qualified homeowners may be eligible for additional rebates of up to $8,000 through the High-Efficiency Electric Home Rebate Act (HEEHRA). Many states and utilities offer additional rebates.
Air-source heat pumps typically last 12–15 years since they operate year-round for both heating and cooling. Geothermal indoor units last 20–25 years, and the ground loop itself lasts 50+ years. Regular maintenance — annual professional tune-ups and monthly filter changes — is essential for maximizing lifespan.
