Heat Pumps Vs Furnaces: Which One is Right For You?

Heat Pumps Vs Furnaces: Which One is Right For You?

Although a heat pump and a furnace can perform the same essential functions for a person's home, they both have specific advantages. Knowing these advantages (as well as the disadvantages) can help with the decision. If you are not sure what is the best option for you and your home, here’s a list of things you’ll want to consider before making your choice:

Location and Climate

One of the most significant factors in determining what to use to heat a home is climate. In general, a furnace is better for harsher winters because heat pumps work by transferring heat from outside the home to inside the house. When it's below 40 degrees Fahrenheit outside, there isn't any heat to move and a furnace will be better equipped to heat your home more efficiently.

Cost of Power

Furnaces and heat pumps run on two different power sources. In general, furnaces run by the fuel of some type although there are some electric furnaces. Heat pumps run on electricity. In general, voltage tends to be less costly than fuel. Heat pumps would be useful in an area where the electric rate is low, and temperatures don't drop down to freezing.

Cooling Needs

Heat pumps can also act as air conditioners. Heat merely pumps transfer heat from one area to another--mainly outside to inside, but if the operation is reversed, it will transfer the heat from inside to outside. The expense of running heat pumps to cool the home is virtually the same expense as an air conditioner, but using a heat pump to cool the house can save money because there would be no need to buy an extra piece of equipment.


In general, furnaces last longer than heat pumps, usually having a 25 to 30-year lifespan. Heat pumps have about a 10 to 15-year lifespan. To balance this, heat pumps typically cost less.
