How a Heat Pump and Air Handler Work Together to Heat Your Home
Looking to upgrade your heating system—or curious about how all-electric heating actually works? You’re not alone.
At Pacific Heating & Cooling, we’re seeing more homeowners ask about heat pumps paired with air handlers—especially as energy costs rise and more people look for efficient, eco-friendly options.
So, how does this system work? Let’s break it down in a way that’s simple, helpful, and designed for real-life comfort.
First: What’s a Heat Pump?
A heat pump is a two-in-one system that can heat your home in the winter and cool it in the summer. But it doesn’t generate heat like a furnace. Instead, it moves heat.
Here’s how:
- In heating mode, the heat pump pulls warmth from the outside air—even when it’s cold—and brings it inside.
- In cooling mode, it works just like an air conditioner, pulling heat out of your home.
Thanks to advanced technology, today’s heat pumps work efficiently in cold climates like Western Washington. And because they just move heat (not create it), they use a lot less energy than traditional systems.
What Does the Air Handler Do?
The air handler is the indoor unit that works with your heat pump. You can think of it as the “air distributor.”
Here’s what it does:
- Blows warm air from the heat pump through your ducts and into your home
- Houses the indoor coil that transfers the heat from the refrigerant into your air
- May include electric backup heat for extra chilly days
It’s designed to work quietly, and efficiently to keepyour comfort consistent. And when it’s matched properly with your heat pump, you’ll feel the difference.
Why They’re Better Together
When your heat pump and air handler are matched—designed to work as a team—you get:
Reliable comfort all year
Lower energy bills
Quieter operation
Longer system lifespan
Full manufacturer warranty coverage
An unmatched system—like installing a new heat pump with an older air handler—can reduce performance, cause breakdowns, and often void the warranty. That’s why we always recommend replacing both together for the best results.
How It Heats Your Home – Step by Step
- Your thermostat tells the heat pump it’s time to heat.
- The outdoor unit pulls heat from the outside air (yes, even cold air has heat!).
- That heat is sent inside through refrigerant lines to the air handler.
- The air handler blows that warmed air into your ducts and throughout your home.
- Your home stays warm, cozy, and energy-efficient.
And when summer returns, the same system cools your home—no extra equipment needed.
