Ductless mini-splits are gaining popularity as highly efficient dual-purpose systems for heating and cooling homes. Are they a good option for your home? Here are some key differences between mini-splits and furnaces for you to consider.

What It Does

  • Mini-Split: Heats and cools your home
  • Furnace: Heats your home

How It Works

  • Mini-Split: Involves one or more indoor units connected through refrigerant lines to an outdoor unit
  • Furnace: Uses fuel such as oil or gas to generate heat and pump warm air throughout your home


  • Mini-split: None needed. In a mini-split system, heated or cooled air flows directly from indoor units into your home.
  • Furnace: Requires ductwork. Furnaces generate warm air, which is pumped through ductwork to the rooms in your home.

Energy Savings

  • Mini-split: More efficient than furnaces. They can heat and cool your specific areas within your home and eliminate wasted energy associated with leaky ductwork.
  • Furnace: Today's furnaces are more efficient than they've ever been. When properly sized and connected to airtight ductwork, a new furnace can contribute to a more energy efficient home.


  • Mini-split: More expensive, but more affordable to operate.
  • Furnace: More affordable to install, but more expensive to operate. 


  • Mini-split: On average, a mini-split can heat and cool your home for 10-15 years. With proper maintenance, your system may last for over 20 years.

  • Furnace: The average furnace lasts about 15 years. With regular tune-ups and maintenance, it may last 20 years or more.
