Do you have:

  • A recent addition on your house?
  • A particular room/rooms that have issues with regulating temperatures year-round?
  • A house with no existing ductwork?

If you answered YES to any of these questions, a ductless system may be the answer to your home comfort issues!


Ductless systems, commonly known as mini-split systems, are a flexible solution for your home's heating and/or cooling needs. Typically, a ductless system contains a wall-mounted indoor unit and an outdoor compressor. Whether you have a room that has challenges with ductwork or a room that has difficulties regulating temperature in, there are several single or multi-zone ductless system styles that can be installed high on the wall, in the ceiling or near the floor to help meet your home comfort needs. Similar to whole-house HVAC systems, the higher the SEER and HSPF ratings, the more energy efficiency the ductless systems will be. Ductless systems come in a variety of configurations and types. Please see below for the various forms:

  • Ductless High Wall Indoor Heat Pump
  • Ductless High Wall Indoor Air Conditioner
  • Alternate Indoor Ductless Unit
  • Single Zone Ductless Outdoor Unit
  • Multi-Zone Ductless Outdoor Unit

While the ductless systems can be a great solution to improve the comfort in your home, it is a difficult decision to know if installing a ductless system is right for your home. We have created a list of Pros and Cons to help make this decision-making process a bit easier.


The benefits of installing a ductless system in your home include, but are not limited to:

  • Installation only requires a very small hole be drilled into the wall
  • Less vulnerable to air leakage
  • Quiet
  • Energy Efficient
  • Can save up to 30% on heating and cooling costs in the rooms where the ductless systems are installed


The downsides of installing a ductless system in your home include, but are not limited to:

  • Installation/Up-Front Costs
  • Design/Aesthetics of the ductless systems (only come in white or beige, cannot be covered up)


While there are many factors to consider when deciding whether a ductless system is the right fit for your home comfort needs, it is important to know that the technicians and office staff at Bob Cermignano Air Conditioning & Heating, Inc. are always there to help guide you along the decision-making process.
