Heat Pumps vs. Electric Furnaces: What The Home Boys Learned From a Real-World Winter Test

Energy efficiency is one of the biggest questions customers ask when they start shopping for a manufactured home. A home can look great, the floor plan can work, and the price can make sense — but what will it actually cost to heat through a real Northwest winter?

That is the question The Home Boys wanted to answer with real numbers.

Instead of relying only on manufacturer claims, general estimates, or advertising materials, The Home Boys worked with NEEM — Northwest Energy Efficient Manufactured Homes — to run a real-world winter comparison. The goal was simple: compare similar manufactured homes, in the same environment, at the same thermostat setting, and see how much energy a heat pump uses compared with a standard electric furnace.

The results were clear. In this test, the heat pump homes used roughly half the energy of comparable homes heated with standard electric furnaces.

Why This Test Was Different

Most heating comparisons are based on estimates, lab ratings, or general rules of thumb. Those can be useful, but they do not always show what a homeowner will actually see on a power bill.

This test was different because the homes were tested under unusually controlled real-world conditions:

• four manufactured homes were tested on The Home Boys lot;
• all four homes were located within a couple hundred feet of each other;
• all homes experienced the same outdoor weather;
• all homes were kept at a constant 68 degrees;
• no one was living in the homes during the test;
• the only other power usage was LED lighting, which uses very little electricity;
• the test ran through the winter months;
• power usage was checked monthly and reported back to NEEM.

That made the comparison especially useful. The homes were not affected by different family habits, cooking, showers, doors opening and closing, people changing the thermostat, or different weather conditions. The main difference was the heating system.

Electric Furnace vs. Heat Pump: The Basic Difference

A standard electric furnace uses electric resistance heat. In simple terms, it works like a large toaster coil or hair dryer with a fan blowing air across it. For every unit of electricity you buy, you get roughly one unit of heat.

A heat pump works differently. It moves heat instead of simply creating heat. Even in cold weather, a heat pump can pull heat from outside air and move it inside the home. Because it is moving heat rather than generating it only through resistance, it can often deliver two to three units of heat for every unit of electricity used.

That is why heat pumps can be so much more efficient than electric furnaces in many Northwest climates.

The electric furnace is still part of the system. In a heat pump-equipped home, the furnace often works as the air handler and backup heat source. It moves air through the duct system and can provide backup heat when conditions require it.

The Four Homes in the Test

The Home Boys compared two smaller homes and two larger homes.

The smaller-home comparison included:

• a home around 1,498 sq. ft. using a standard electric furnace;
• a Golden West Dream 563 around 1,512 sq. ft. using a heat pump;
• both homes had the same insulation package.

The larger-home comparison included:

• a Fleetwood home around 1,770 sq. ft. using a standard electric furnace;
• a Marlette home around 1,760 sq. ft. using a heat pump;
• both homes were tested under the same winter conditions.

All four homes were set to 68 degrees throughout the test.

Smaller Home Results: About 50% Average Savings

In the smaller-home comparison, the heat pump home used much less electricity than the electric furnace home.

The monthly results were:

1. November 2025
   • Electric furnace home: 1,732 kWh
   • Heat pump home: 1,090 kWh
   • Savings: 37%
2. December 2025
   • Electric furnace home: 2,020 kWh
   • Heat pump home: 811 kWh
   • Savings: 60%
3. January 2026
   • Electric furnace home: 2,834 kWh
   • Heat pump home: 1,156 kWh
   • Savings: 59%
4. February 2026
   • Electric furnace home: 1,299 kWh
   • Heat pump home: 716 kWh
   • Savings: 45%

Across the full four-month test period, the heat pump home averaged about 50% energy savings compared with the electric furnace home.

That is not a small difference. That is the kind of difference a homeowner can feel every month on the utility bill.

Larger Home Results: About 48% Average Savings

The larger-home comparison showed the same pattern. The Fleetwood home with electric heat was compared with the Marlette home using a heat pump.

The monthly results were:

1. November 2025
   • Fleetwood electric furnace home: 1,768 kWh
   • Marlette heat pump home: 797 kWh
   • Savings: 972 kWh
   • Percent savings: 55%
2. December 2025
   • Fleetwood electric furnace home: 2,128 kWh
   • Marlette heat pump home: 942 kWh
   • Savings: 1,186 kWh
   • Percent savings: 56%
3. January 2026
   • Fleetwood electric furnace home: 2,967 kWh
   • Marlette heat pump home: 1,756 kWh
   • Savings: 1,211 kWh
   • Percent savings: 41%
4. February 2026
   • Fleetwood electric furnace home: 1,525 kWh
   • Marlette heat pump home: 897 kWh
   • Savings: 627 kWh
   • Percent savings: 41%

Across the winter test period, the larger heat pump home saved an average of about 999 kWh per month, or about 48%.

Again, the result was clear: the heat pump cut heating energy use by roughly half.

Weather Conditions During the Test

The homes were tested during real winter weather. The average outside temperatures were:

• November: 41 degrees;
• December: 39 degrees;
• January: 35 degrees;
• February: 38 degrees.

The thermostat inside each home was set to 68 degrees. That means each home had to maintain the same indoor temperature while dealing with the same outdoor weather.

The average temperature difference between inside and outside was:

• November: 27 degrees;
• December: 29 degrees;
• January: 34 degrees;
• February: 30 degrees.

This is why the test is so useful. The homes were not being compared across different towns, elevations, weather patterns, or family habits. They were tested side by side in the same environment.

What the Savings Mean for Homeowners

In this test, the heat pump homes saved roughly half the heating energy compared with homes using standard electric furnaces.

At an example rate of 12 cents per kilowatt-hour, that can translate into meaningful monthly savings during the heating season. Junior explains it simply: saving around $100 or more per month on heating costs is a big deal for many homeowners.

The exact savings will depend on several factors:

• home size;
• insulation package;
• outdoor temperature;
• utility rate;
• thermostat setting;
• heat pump model;
• how the family lives in the home;
• whether doors are opened frequently;
• how much hot water and appliance use is happening.

But even with those variables, this test shows the direction clearly. A heat pump can dramatically reduce heating energy compared with a standard electric furnace.

Heat Pump vs. Air Conditioner

Many buyers already know they want cooling. In that case, the comparison is not only heat pump versus no heat pump. The more practical comparison is often air conditioner versus heat pump.

A standard air conditioner only cools. In the Northwest, especially in areas like Spokane, North Idaho, Western Montana, Eastern Washington, and Central Washington, air conditioning may be heavily needed for 45 to 60 days a year. If you install only an air conditioner, you get summer cooling, but your home still uses the electric furnace for winter heat.

A heat pump gives you both:

• cooling in the summer;
• efficient heating in the winter.

In the video, Junior explains the approximate installed cost difference this way:

• air conditioner: about $7,500 installed;
• heat pump: about $8,750 installed;
• difference: about $1,250.

Because the heat pump can save so much energy during the heating season, that extra cost can often pay back in roughly a couple of years. After that, the savings can continue over the life of the system.

Newer Inverter Heat Pump Technology

The video also compares older heat pump technology with newer inverter-style heat pumps.

The newer Carrier inverter heat pump uses variable-speed technology. Instead of simply turning fully on or fully off, it can adjust how hard it works. That can improve comfort, reduce energy use, and help the system run more smoothly.

Junior also explains an important cold-weather difference:

• older heat pump technology was effective down to around 5 degrees below zero;
• the newer Carrier inverter heat pump is rated down to approximately 22 degrees below zero.

That matters in the Northwest. Many areas in Eastern Washington, North Idaho, and Western Montana can see very cold winter days. A heat pump that can keep working efficiently at lower temperatures gives homeowners more confidence and better performance through more of the season.

Why a Heat Pump Is a Smart Investment

A heat pump is not just a comfort upgrade. It is a long-term operating-cost decision.

A standard electric furnace may cost less upfront, but it uses more electricity during winter. A heat pump may cost more than a cooling-only air conditioner, but it can reduce heating costs enough to pay back the difference.

For many buyers, the heat pump makes sense because it delivers:

• summer cooling;
• winter heating;
• lower heating energy use;
• better efficiency;
• more comfortable temperature control;
• potential monthly utility savings;
• long-term payback.

Even if a buyer cannot add a heat pump at the time of purchase, it may be worth planning for later.

What This Means for Manufactured Home Buyers

The biggest lesson from this test is that modern manufactured homes can be very energy efficient when the right systems are installed.

All four test homes had strong insulation packages and were kept at the same temperature. The major difference was the heating system. The homes with heat pumps used far less electricity.

That matters because affordability is not only about the home price. Monthly utility costs are part of homeownership too. A home with a lower purchase price but higher monthly energy bills may not be as affordable over time as it looks at first.

A heat pump can help reduce that long-term operating cost.

Key Takeaways From the Test

The Home Boys’ winter test showed several important things:

• heat pump-equipped manufactured homes used about half the heating energy of similar homes with electric furnaces;
• the smaller home comparison showed about 50% average savings;
• the larger home comparison showed about 48% average savings;
• the homes were tested in the same location and same weather;
• all homes were set to 68 degrees;
• the results were based on real power usage, not just manufacturer claims;
• the heat pump difference can show up every month on the utility bill;
• upgrading from an air conditioner to a heat pump can be a smart long-term decision.

The Bottom Line

The Home Boys tested four manufactured homes through a Northwest winter to answer one practical question: is a heat pump really worth it?

Based on this real-world comparison, the answer is yes.

The heat pump homes used roughly half the heating energy compared with similar homes using standard electric furnaces. In the smaller-home comparison, the heat pump saved about 50% on average. In the larger-home comparison, the savings averaged about 48%.

For buyers shopping for a manufactured home in Washington, Idaho, Oregon, or Montana, a heat pump is one of the smartest upgrades to consider. It can provide cooling in the summer, efficient heating in the winter, better comfort, and lower monthly energy use.

The Home Boys can help buyers compare electric furnaces, air conditioners, and heat pumps so they can choose the system that makes the most sense for their home, climate, and budget.
