Heat Pump

A heat pump is an HVAC system that heats and cools by moving heat rather than generating it. In winter it pulls heat from outdoor air, ground, or water and moves it indoors; in summer it reverses to remove heat from the home. Heat pumps are highly efficient and can reduce energy costs and emissions compared to traditional systems.

💡 Key Takeaways

In winter it pulls heat from outdoor air, ground, or water and moves it indoors; in summer it reverses to remove heat from the home. Heat pumps are highly efficient and can reduce energy costs and emissions compared to traditional systems.
  • Efficiency varies by climate; cold-climate models perform well in lower temps.
  • Proper sizing prevents short cycling and uneven comfort.
  • Many heat pumps qualify for rebates and tax incentives.
