What is a Mini-Split

Written by VS Admin

A mini-split (also known as a ductless mini-split) is a heating and cooling system which does not rely upon ductwork. A mini-split controls the temperature of a specific area, such as a specific room in the home.  It has two components, an outdoor compressor and an indoor, wall-mounted, air-handling unit.   Mini-splits have a smaller footprint – they take up less space and are much more efficient then central heating & air-conditioning systems.  Traditional central heating & air systems lose as much as 30% of their output in forcing air throughout the home.  This inefficiency results in higher electricity usage and higher bills.

Where are mini-splits used?


Mini-splits have come a long way over the years, and today can replace central heating and air through the use of multiple mini-splits working together to cover the entire home.  However, mini-splits are typically used in the following situations:

  • Garage apartments, sunrooms. New additions where ducts will not be installed.  The mini-split air-conditioner and heat pump will be sized to fit the room and will not draw from the central HVAC system.
  • Adding heating and cooling to a home without ducts. Adding ducts can be very expensive or impractical in some older homes.
  • Empty-nesters who no longer need to heat and cool the entire home. Shutting off rooms using the grille can cause pressure imbalance in the HVAC system and may even allow mold to develop.  The better answer is to run the HVAC at its lowest level and use a mini-split for the remaining are of typical use.
  • To balance a particular heating/cooling issue in the home. You likely have an area in the home which, in spite of the HVAC, is always too hot or cold.  A kitchen is a good example.  A mini-split can bring that problem area a solution.

What’s Next?

  • The wise homeowner will employ a qualified contractor (like Garland Heating & Air) to design and install the mini-split.
  • To work properly the unit must be the correct size for the room. Your contractor will assess the requirement, no more or less than needed.
  • The system requires the technical ability and experience of a qualified team, and you’ll be dollars ahead to have it done correctly.
