What Are the Pros and Cons of Having Ductless Mini-Splits?

The popularity of ductless mini-splits continues to rise as an alternative to single-room or small-space cooling and heating. According to industry figures, the annual growth rate in ductless mini-splits is estimated to average around 4.3% in the coming years as more homeowners discover the benefits of these compact, efficient heat pumps.

Ductless mini-splits can solve many problems when it comes to adding cooling and heating to individual rooms where ductwork for a central system is not present and window units are not desired. However, a ductless system also has certain downsides that should be considered. Here’s a brief pro-and-con comparison of ductless technology.

  • Pro: They are highly efficient with SEER (Seasonal Energy Efficiency Rating) in the range of between 20 and 25. A typical mini-split can reduce cooling and heating costs for a single room by around 30%.
  • Con: The high efficiency and advanced technology of mini-splits often comes at a high initial purchase price.  This is a significant expense, though still far lower than installing ductwork connected to a central AC or furnace.
  • Pro: A single ductless heat pump can serve multiple indoor air handlers in different rooms, maintaining different temperatures. This serves the same purpose as a traditional ducted zoning system but without the expense and disadvantages of ductwork.
  • Con: Not for large spaces. While a standard ductless unit can keep a single room comfortable and efficient, larger square footage such as a living room or rooms with vaulted ceilings will require installation of more than one ductless air handler for adequate temperature control.
  • Pro: Quiet operation with noise levels as low as 19 decibels. No ductwork should sound like loud rushing air or banging noises as ducts expand and contract.
  • Con: Higher visibility. Though only about 7 inches deep, a ductless air handler installed on a wall still sticks out and is more conspicuous than a standard HVAC air vent.
