Most people think a heat pump is just a box outside their home…
But the real magic is in **how the air moves inside**.
Here’s what’s actually happening:
1. Your system pulls in *return air* from your home
2. It heats or cools that air using heat pump technology
3. Then sends it back out as *supply air* to every room
No air ducts? No problem
Ductless mini splits do the same thing, just room by room without ductwork.
And here in Seattle’s mild climate, heat pumps are one of the most efficient ways to stay comfortable year-round:
- Lower energy bills
- Heating + cooling in one system
- Consistent, even comfort
Check out the diagram to see how it all works
