Heat Pump Vs. Furnace: What’s the Difference?

Table of Contents

There are several ways to generate heat for your home in Ohio, and much of it has to do with the availability of energy resources and energy efficiency. Let’s take a look at the similarities and differences between heat pumps and furnaces to understand better what type of heating system may be best for you.

What Is A Heat Pump?

When researching heat pumps, you will find that there are several different types available, including air-source heat pumps, geothermal heat pumps, ground-source heat pumps, and water-source heat pumps. At Logan Services, we offer air-source heat pump systems. These systems are the most common pumps used to handle the tough winter climate in Ohio.

So how do these electric heat pump systems work? The heat pump unit is positioned outside the home. It absorbs heat from the outdoor air and delivers it to the indoor air handler (electric furnace) through refrigeration. The air flows over a hot indoor coil powered by electricity. Then, the air flows up through the ductwork to heat your home. 

Heat pumps are not as efficient when temperatures dip because there typically aren’t enough hot air molecules from the outdoor air to be transferred inside. Extreme cold causes more work for the heat pump and higher energy usage. You will have to rely on backup heat sources, such as the heat strips from the indoor air handler, to keep your home comfortable. 

In air conditioning mode, the heat pump will reverse its refrigerant cycle through a reversing valve to transform into a cooling system. Have you ever felt the heat from an air conditioner in the summertime?  That’s the heat from your house. The outdoor unit in cooling mode removes heat/humidity from the inside and expels it to the outdoors, making your home feel comfortable.

What Is A Furnace?

Contrary to a heat pump, a furnace uses natural gas, oil, or propane as a fuel source to generate heat for the entire dwelling space. Furnaces are typically located indoors in a basement, utility closet, or, sometimes, in an attic. A furnace works with an initial call for heat from the comfort control (the thermostat).  The vent motor engages and starts to spin.  Then it pulls in a pressure switch which sends a signal to the circuit board to begin the ignition process, and the fuel source ignites. A thermocouple or a flame sensor senses the flame. Once that happens, the blower is signaled to start. The blower sends air across the heat exchanger and provides warm air for the home.  

Heat Pump Vs. Furnace

The fuel source is the major difference between a furnace and a heat pump. A heat pump operates on electricity, while a furnace uses natural gas, heating oil, or propane. A heat pump is positioned outside the home and is generally connected to an electric furnace called an air handler. 

However, there are a few other differences you should consider:


A furnace requires ventilation either through metal or PVC piping or even through a chimney flue. A heat pump does not need to be ventilated.

Furnaces can produce harmful gasses when heat exchangers crack due to expansion.  This can cause carbon monoxide poisoning. A furnace must be vented properly; otherwise, it could be a serious safety hazard. A heat pump does not produce carbon monoxide and does not require additional ventilation.


There’s not much variation in the upfront costs of an air source heat pump vs. a gas furnace system. Systems range in price from $6,000 to $16,000+ and can vary based on system size, energy efficiency, and additional air quality options such as air cleaners, UV-light systems, and more.

Expect to pay a bit more for high-efficiency heat pumps, but keep in mind these systems will do a much better job of keeping your home comfortable by producing consistent temperatures throughout the home and eliminating more humidity in the summertime. 

When researching your heat pump installation project, it’s always best to get an in-home estimate for the work needed. This will allow a trained professional to properly give you heat pump choices that will meet the needs of your home, lifestyle, and budget. 

Dual fuel systems allow homeowners to generate heat with either electric or fossil fuels. As energy costs are rising, a dual-fuel system can give any homeowner peace of mind by having some control over utility usage and costs when cold weather strikes. 


A heat pump requires clean air filtration. It’s important to get outdoor units cleaned annually through a maintenance plan. During your maintenance plan visit, a service technician will ensure that all heat pump components are in proper working condition and that nothing has weakened during the usage season. The service technician will also clean your system’s coils on the inside and outdoor unit of your electric heating system. They will also make sure there’s clearance around the outdoor unit, being mindful that there are no bushes or debris that can damage your outdoor heat pump. 

Like heat pump maintenance, a gas furnace requires proper airflow with clean filtration.  During a maintenance visit, the technician will also check and clean the burners, flame sensors, and more. 

Whether using an electric system or a traditional natural gas-burning furnace, it’s always important to routinely change the air filter. Homeowners should remove any dirty filters monthly and replace them with fresh, clean filters to ensure proper system airflow and healthy indoor air quality.


In colder weather, fuel-burning furnaces typically provide warmer, more consistent heat.  A heat pump will produce cooler heat which varies with the temperature outside. As it gets colder outside, the heat pump will produce less warm heat, and the pump will have to be supplemented by a backup fuel-burning furnace or an electric air handler. In the winter, natural gas is generally the most efficient and warmest way to heat your home in Ohio. 

Energy usage

Remember, a heat pump uses electricity to heat and cool your home, whereas a furnace uses gas, propane, or oil. Some high-efficiency gas furnaces will operate at 96% efficiency, which can help reduce your fossil fuel utility usage. You can also reduce the number of fossil fuels and lower your carbon footprint by using a heat pump on milder days vs. running a gas or propane furnace at full blast to heat your home. 

Expected lifespan

A gas furnace operates 4-5 months each year. Most heat pumps work twice as much because they operate both in the summer (for cooling cycles) and the winter (for heating cycles). 

The lifespan of a heat pump usually isn’t as long as a traditional furnace because seasonality places twice the wear and tear on the outdoor unit. You’re doing great if you get 10 years or more out of a heat pump. The life expectancy for a furnace is 12-15 years.

What Are The Benefits of a Heat Pump?

One of the biggest benefits of a heat pump is that it can both heat and cool your home. Operating a fuel-burning furnace may be best during the coldest days of the year. 

Another benefit of a heat pump system is not having to worry about carbon monoxide poisoning. With a furnace, you must have working carbon monoxide detectors throughout your home. 

Heat pumps can be used in all seasons. On the contrary, if you don’t have a heat pump, you’ll need a furnace and an air conditioner to stay comfortable year-round. These pumps can be a great option or alternative to air conditioners since you can utilize a heat pump for warmth on chilly days that tend to be slightly milder in temperature. This setup can offer you optimal heating and cooling performance.

Which System is Right For You?

If you have an all-electric home, it’s important to consider a heat pump if you don’t already have one. If you want to improve your home’s energy or utility usage, a dual-fuel heating system can be an excellent solution for your home.
