How Does a Heat Pump Work—and Why Should You Consider One?



For many homeowners, the term “heat pump” feels a bit mysterious. Is it like a furnace? A water heater? Something for the car? If you’ve asked the same questions, you’re not alone. In a recent survey of 250 Illinois homeowners, more than half said they don’t feel confident explaining how a heat pump works.

But once you understand what a heat pump does and why so many experts recommend them, the picture becomes surprisingly simple and compelling. This guide breaks down in plain language how heat pumps work, what benefits they offer and why now is a great time to consider installing one.

What Exactly Is a Heat Pump?

A heat pump is a highly efficient system that moves heat rather than generating it, using the same basic technology that makes your refrigerator cold—just in reverse.

This core idea is something many survey respondents got right: numerous homeowners described a heat pump as a device that “moves heat from one place to another.”

Here’s the simplest way to think about heat pump systems:

  • In winter, a heat pump pulls heat from the outdoor air (yes, even cold air contains heat!) and transfers it indoors.
  • In summer, it reverses direction, pulling heat out of your home to cool it.

Because it moves heat instead of burning fuel to create heat, it's a far more energy-efficient heating and cooling method than traditional HVAC systems.

Do Heat Pumps Really Work in Cold Climates?

This is one of the biggest questions homeowners have, especially in states like Illinois.

In fact, only 38% of surveyed homeowners believe heat pumps work in cold climates, showing it's a common misconception.

But modern cold-climate heat pumps are designed to perform reliably even when temperatures drop well below freezing. They use advanced refrigerants, variable speed compressors, and smarter defrost cycles to maintain efficiency and comfort throughout the winter.

If you’re replacing an older furnace or AC unit, a heat pump can often provide year-round comfort without the energy waste of two separate systems.

How Does a Heat Pump Heat and Cool Your Home?

  1. Heat absorption: even cold air contains thermal energy. The heat pump’s outdoor unit absorbs that energy. 
  1. Heat transfer: a refrigerant circulates between the indoor and outdoor units, moving heat through compression and expansion cycles. 
  1. Heat distribution: inside your home, the heat pump releases heat into your ductwork or a ductless indoor air handler. 
  1. Reversing valve: in warmer months, the system reverses direction, becoming an air conditioner. 

Although heat pumps are sophisticated machines, the underlying principle is simple: they move heat instead of creating it. Many homeowners in the survey expressed confusion about whether heat pumps “generate heat,” “pump hot water,” or “work like a car heater,” highlighting the need for clear explanations like this one.  

Why Consider Installing a Heat Pump?

They’re more efficient than furnaces and AC units

Around one third of homeowners already believe heat pump systems are more efficient than traditional systems—and they’re right.

Because they move heat rather than generate it, heat pumps can deliver up to three times more heat energy than they consume in electricity, translating into lower utility bills.

They provide heating and cooling in one system

Although only 42% of homeowners know this, heat pumps replace both a furnace and an air conditioner, simplifying your entire home comfort setup.

They help lower energy bills

Lower energy bills were the #1 most influential factor for homeowners considering a heat pump, selected by 69% of respondents.

They’re better for the environment

One third of survey participants correctly identified that heat pumps are better for the environment because they don’t burn fossil fuels and significantly reduce carbon emissions. There are even rebates and energy efficiency tax credits to help with the cost of heat pump installation.

They increase safety

Heat pumps eliminate combustion, reducing risks associated with gas furnaces, including carbon monoxide leaks.

Cost: The #1 Concern for Homeowners

In the survey, installation cost was the top concern, selected by 42% of homeowners. Most homeowners said they would feel comfortable paying $10,000 or less upfront.

The good news is most systems fall within that range after incentives, and this is where energy efficiency rebates make a huge difference.

Rebates & Tax Credits: A Major Opportunity (That Hardly Anyone Knows About)

Despite the availability of federal and local incentives, only 23% of homeowners knew rebates existed, according to the survey.

And yet, rebates are one of the strongest motivators:

  • When homeowners learned about incentives, 62% said they’d be likely to consider a heat pump.

If you’re a homeowner trying to keep upfront costs manageable, checking available rebates can significantly reduce the financial barrier.

What Homeowners Want to Know Before Deciding

The survey revealed the topics homeowners most want explained clearly:

  • Cost vs. savings (74%)
  • Maintenance expectations (66%)
  • How heat pumps work (59%)
  • Lifespan and warranty (57%)
  • Cold weather performance (54%)
  • Rebates and incentives (52%)

If you’re considering a heat pump, these topics are great starting points for building confidence and making an informed decision.

Should You Consider a Heat Pump?

If you’re looking for any of these features in a new HVAC system, a heat pump is absolutely worth considering:

  • Lower monthly energy bills
  • High-efficiency heating and cooling
  • A more environmentally friendly HVAC option
  • A system that performs year-round
  • Access to significant rebates and tax credits
