Ductless Mini-Split Systems | Heating and Air Conditioning

An addition to a home adds valuable living space, though it also adds additional square footage that requires heating and air conditioning. Adding duct work, when possible increases the workload on the HVAC system, and a room addition may require a new HVAC system to be installed, or the installation of a separate system for the addition. A ductless mini-split air conditioner may be the solution you need, and is available as a heat pump. The following pros and cons of the ductless mini-split systems can assist you in deciding if this system is right for you.

Advantages of the Ductless Mini-split System

  • Ductless systems consist of an outdoor unit, a streamlined indoor air-handling unit (AHU), and a compact piping system, which allow for quick installation typically in one day. A mini-split system only requires a three-inch hole in an exterior wall to connect the indoor and outdoor components.
  • The low-profile AHU may be mounted flush to a wall, ceiling or floor. The AHU can also be concealed, as long as there is space if there’s space behind these surfaces.
  • Ductless mini-split systems are available in Energy Star qualified models.
  • The ductless system offers greater efficiency and personalized comfort for the occupants of each zone.
  • Ductless systems offer versatility. They can be used for retrofits, additions, home offices, garages, pool houses, guest houses, rental properties, difficult-to-condition rooms and homes where ducts can’t be installed.
  • The ductwork in central heating and air conditioning systems can be a source of indoor air pollution by dispersing contaminants throughout the home. The interior components of a ductless mini-split system uses advanced filtration to purify the air leaving each air handling unit in each zone. With select models, up to 99.9% of bacteria, viruses and other pollutants can be eliminated from the air moving through the unit improving the air quality, and benefitting those with allergies, asthma and other respiratory illnesses.
  • Small size and flexibility for heating and air conditioning individual rooms, and can condition up to four rooms, each with their own dedicated air handling units connected to one outdoor unit.
  • Because these systems are ductless, they eliminate the energy losses associated with the leaky ductwork of central air systems. Duct air losses can account for up to 30 percent of the energy consumed by heating and air conditioning.
  • Available as air conditioning only, or as a heat pump.
  • The mini-split system provides individualized temperature control in each room containing an air handler. You don’t have to heat or cool unused rooms providing significant savings on energy costs. A remote control enables you to adjust the temperature.
  • A mini-split system requires minimal maintenance, consisting of filter changes, and periodic professional maintenance by your heating and air conditioning technician to maintain performance and extend the lifespan.
  • Ductless systems provide quiet operation. An important factor when the HVAC system must be located near bedrooms.
  • If you have rooms that tend to be colder or hotter than others, a ductless system offers a solution for a consistent temperature.


  • One potential drawback is the cost of the equipment compared to other solutions such as window air conditioners. However, the energy saved and the increased comfort is substantial when compared.

The proper installation of any HVAC system is essential for the units efficiency and performance. For this reason, you should always use a qualified and licensed HVAC contractor to provide heating and air conditioning installation. This will prevent the problems associated with an improperly sized or poorly installed system.

With proper installation and sizing, ductless mini-split heat pumps provide greater comfort, cleaner air, enhanced efficiency, and quiet operation.
