What Are Ductless Mini Split Systems?

Ductless Mini Split | Cincinnati | Nelson Comfort

Ductless mini-split heat pump systems are a type of HVAC system that provides both heating and cooling without the use of duct work. They can be added to a home to complement existing heating solutions such as hydronic or radiant systems. A ductless mini-split has both interior and exterior components, like other heat pump systems.

Advantages of Ductless Mini-Splits

Ductless mini-splits are small in size and flexible in application, making them ideal for installation in homes or areas where space is limited. Models can be installed on the wall, on or flush with a ceiling, or standing on the floor. They are also easier to install compared to other types of heating and cooling systems, meaning installation can be completed faster with less labor expense.

Their lack of duct work eliminates the expense of installing and maintaining ducts, making them an ideal choice for homes with no existing duct work. No ducts means no duct work energy losses, which can equal as much as 30 percent of a home’s total HVAC energy consumption!

Ductless mini-split systems allow for zoned heating and air conditioning. Individual air handling units can be installed in various rooms or areas of the home, allowing for individual control of temperatures in the zone. Zoning reduces energy use and saves homeowners money.

Disadvantages of Ductless Mini-Splits

Some homeowners do not like the appearance of ductless mini-split equipment in their living spaces. Ductless systems utilize a fan and can be louder than central air systems, adding noise to your living can lead to indoor air pressurization causing building envelope damage, drafts and unstable temperatures. Because air is not recirculated, it is only filtered once through a ductless system rather than continuously through a central air system; ductless systems alone don’t offer the same level of filtration and humidity control as central air systems.
