The Science Behind How a Heat Pump Works
A heat pump doesn't create heat - it moves it. Here's the simple science behind why a mini split system is the smartest way to heat and cool your home.
Shop Mini Splits »Unlike a furnace that burns fuel to generate heat, a heat pump - the technology at the core of every mini split system - transfers heat from one place to another using basic thermodynamics. That single difference is why heat pumps use so much less energy.
The Heat Pump Cycle, Step by Step
1. Heat Absorption
Refrigerant inside the mini split absorbs heat from outdoor air, even in cold temperatures.
2. Compression
The refrigerant is compressed, raising its temperature and pressure significantly.
3. Heat Release
The now-hot refrigerant releases that heat into your home through the indoor unit.
4. Expansion
The refrigerant expands and cools, resetting for the next cycle - reverse it all for cooling mode.
