To determine if a heat pump or furnace is better for your home, you also need to know how they differ.
A heat pump will win the battle for energy efficiency. While a reliable, energy-efficient furnace can operate at 95% energy efficiency, a heat pump can run at almost 300% efficiency. That means it creates 300 times more heat than the energy it uses.
Don’t count your furnace out just yet! When temperatures drop below 25 degrees Fahrenheit, a furnace becomes more energy-efficient because the heat pump doesn’t have enough warm air around it to draw from.
The average life span of a heat pump is around 15 years. Some heat pumps will fail after 10 years or so with heavy use. Heat pumps should be regularly maintained to keep them as efficient as possible.
The average life span of a furnace is 15 to 20 years. Even with heavy use, furnaces can typically outlast a heat pump. Furnaces should be professionally maintained at least once a year, with twice-a-year service being ideal.
Maintenance should be thorough to ensure your furnace lasts to its full capacity.
