Ductless Mini Split Air Conditioners


Good Morning Friends,

Today I would like to discuss the advantages and disadvantages of ductless air conditioners. Ductless air conditioners were designed to provide cooling where there are no air ducts available to deliver adequate cooling. The following are examples of homes that could benefit from ductless air conditioners.

  1. Homes that are heated with a boiler and perimeter radiators or in-floor radiant heat.
  2. Homes that are heated with electric baseboard heat.
  3. Homes with rooms that are not getting enough cool air from the existing air conditioning system.
  4. Third floor rooms that are always too warm in the summer.
  5. Rooms with unusually high loads such as offices with computers, kitchens or sun rooms.

All of these rooms would benefit from the great cooling and dehumidification capabilities of a ductless air conditioner.

Ductless units have the following advantages:

  1. They cool exceptionally well where standard ducted systems cannot.
  2. They are great at removing the humidity making the home feel dry in addition to cool.
  3. They can also be a source of heat. This saves a lot of money when you are currently using electric baseboard heat.
  4. They allow for independent temperature control of the rooms that they service.

The disadvantages are:

  1. There is a visible unit mounted in the treated room. Please see the videos below that feature some very nice looking units that can blend in to any decor.
  2. They cannot be controlled by a conventional 7-Day programmable thermostat. They use a wireless remote.
  3. Many unprofessional contractors install these units, often incorrectly, causing much grief and equipment failure. Buyer BEWARE when selecting a contractor to install a ductless mini-split.

Technology has advanced and now ductless units are available with completely concealed units. They also make some very nice looking units. Please see the 2 videos below. You can leave a comment for me with any questions or applications and I will be happy to help you pick a unit that will work best for you.
