Do Heat Pumps Actually Save You Money?

Heat pumps are known for being energy-efficient—but what does that mean for your monthly energy bills?

The answer depends on what type of heating or cooling system you’re replacing. For some households, a heat pump can dramatically lower energy costs. For others, the biggest benefits are improved comfort, air conditioning, and long-term home value.

Here’s what Eastside homeowners can typically expect:

Replacing a Gas Furnace

If you currently heat your home with natural gas, switching to a heat pump may result in little or no change to your monthly energy bills. That’s because natural gas remains a relatively low-cost fuel in Washington.

However, heat pumps are still incredibly efficient systems—providing 2–3 times more heating efficiency than a traditional gas furnace. And unlike a furnace, a heat pump also provides high-efficiency air conditioning during the summer.

For many homeowners, the value comes from:

• Year-round heating and cooling in one system

• Improved indoor comfort

• Cleaner indoor air

• Reduced carbon emissions

• Avoiding the need for a separate A/C system

Replacing Electric Baseboards or Resistance Heat

This is where heat pumps really shine!

Homes using electric resistance heating—like baseboards, wall heaters, or ceiling heat—can often reduce heating energy use by 50% or more after installing a heat pump.

Traditional electric resistance systems work a bit like a toaster: they generate heat directly, which uses a large amount of electricity. Heat pumps work differently. Instead of creating heat, they move heat from outside into your home—making them far more efficient.

For many households, this can mean significantly lower winter electricity bills while also gaining whole-home cooling for summer.

Replacing Portable or Window A/C Units

If you rely on portable or window air conditioners, upgrading to a heat pump can also reduce cooling costs.

Heat pumps—especially ductless systems—are typically much more efficient than portable A/C units and can lower cooling energy use by 25% or more.

You’ll also gain:

• Quieter operation

• More even temperatures throughout the home

• Better indoor comfort during heat waves

• A permanent cooling solution without bulky window units

Boost Your Heat Pump Savings with Weatherization

A heat pump performs best when paired with a well-insulated, air-sealed home.

Simple weatherization improvements—like insulation and air sealing—can help your home hold heat in winter and stay cooler in summer. That means your heat pump doesn’t have to work as hard, improving comfort and lowering energy use even further.

Beyond Energy Bills: Other Benefits

• Year-Round Comfort

  • Heat pumps both heat and cool your home, helping maintain more consistent indoor temperatures throughout the year. And during increasingly hot Pacific Northwest summers, reliable cooling can make a huge difference in comfort and health.

• Increased Home Value

  • Installing a heat pump may increase your home’s value by an estimated 2–3%, making it an investment that can benefit you now and later.

• Reduced Carbon Emissions

  • Switching from fossil fuel heating to an electric heat pump can reduce your household carbon emissions by 92% over the lifetime of the system.
