What Are the Main Differences Between a Furnace vs Heat Pump?
The two biggest distinctions between these systems are their fuel sources and their versatility. Furnaces rely on combustion (gas/propane) and require venting, while heat pumps run on electricity and offer year-round climate control.
Mike Lea, co-owner of Lea Heating & Air Conditioning in East Dundee, IL, explains the differences between heat pumps and furnaces by their fuel source, need for a combustion process, and heating and cooling capabilities.
“A furnace uses natural gas or propane to heat your home, whereas a heat pump uses electricity,” Lea said “Due to a combustion process of a gas furnace, a furnace requires venting to the exterior. A heat pump can do double duty as both a source of heating and cooling, utilizing an outdoor condenser, which is your heat pump, and an indoor evaporator coil and copper tubing line set. Then, inside you have your air handling unit or your furnace as a means of moving air around the home.”
How to Choose: Heat Pump or Furnace?
Energy Efficiency
Climate and Weather Conditions
- Heat Pumps: These systems are highly efficient in moderate climates with mild winters. While historically less effective in freezing temperatures, modern cold climate heat pumps are now a reliable choice for colder regions, providing consistent warmth even when temperatures drop.
- Furnaces: Furnaces are a proven, powerful choice for climates where temperatures regularly fall below freezing. They generate consistent, powerful heat by burning fuel, ensuring reliable warmth in even the most extreme cold.
Cost
- Upfront Cost: Heat pumps typically have a higher initial installation cost. Furnaces generally have a lower upfront cost.
- Operating Cost: The high efficiency of heat pumps often leads to significant long-term savings on monthly energy bills. Furnaces may have higher operating costs due to fuel consumption. It's important to weigh the initial investment against long-term savings.
