Heat Pump vs Air Handler: What’s the Difference for Toronto Homeowners?

If you’re exploring heating and cooling options for your Toronto home, you may have come across the terms “heat pump” and “air handler.” While they’re both crucial for comfort, they serve different roles. At Temperature Care, we break down what each one does and help you decide what’s right for your HVAC system.

What Is a Heat Pump?

A heat pump is a highly efficient unit that provides both heating and cooling by transferring heat between your home and the outdoors. In winter, it brings heat in; in summer, it moves heat out—keeping your home comfortable all year.

Can be paired with either ducts (for whole-home systems) or used as ductless mini-splits
Offers significant energy savings and qualifies for government rebates

What Is an Air Handler?

An air handler is an indoor component of many HVAC systems. It moves (or “handles”) air throughout your home, working alongside a heat pump, furnace, or AC.

Contains a blower, air filter, and sometimes an electric heating element
Distributes heated or cooled air through ductwork
Does not generate heating or cooling on its own—works with a heat pump or AC

How Do They Work Together?

In a heat pump system:
The heat pump (usually outside) generates heating or cooling.
The air handler (inside) circulates that conditioned air throughout your home.
For ductless systems:
Mini-split units combine the “air handler” and “heat pump” functions in one wall-mounted unit.

Benefits of Each

Heat Pump:

Highly efficient heating and cooling
Can reduce your utility bills by up to 50%
Works even in cold Toronto winters with the right model

Air Handler:

Works with heat pumps, ACs, or furnaces
Provides better air circulation and filtration
Often includes options for advanced air quality add-ons (like humidifiers or UV lights)

When Do You Need an Air Handler?

If you’re upgrading to a central heat pump but don’t have a furnace (or want electric backup heating), you’ll likely need a new air handler.
Ductless heat pumps (mini-splits) don’t require a separate air handler.

Cost, Maintenance & Rebates

Heat pumps qualify for major rebates:
- Canada Greener Homes Grant
- Enbridge Home Efficiency Rebate Plus
Both air handlers and heat pumps should be maintained annually for best performance and air quality.

Which System Is Right for You?

Choose a heat pump for energy savings, year-round comfort, and the lowest carbon footprint.
Pair it with an air handler if you want central ducted heating/cooling and better air circulation.
