Mini-Split or Ductless Air Conditioners
Like central air conditioners these units have a split design but use air ducts making the units easier as less expensive to install than central air conditioning. The mini-split has at lease one unit that sits inside and that is the air handler. The compressor sits outside of the home and air handler sits inside the home. Some models come with multiple air handlers that will use one compressor.

Mini-Split Air Conditioners FAQs

How do I choose a mini split air conditioner?
Like all air conditioners you need to know how many BTUs you need to cool the area you are trying to cool. You also need to consider the number of air handles that you need normally one air handler per room is what you would need but, if your home has open areas you may be able to cool multiple rooms.

There are many options for types of air vents that you can purchase some sit in the home and are mounted on the walls and some can be mounted in the ceiling. It is important that you talk to a person who is certified to install air conditioning about your options to help you decide which would meet your needs.

What is dual zone and triple zone?
Dual zone means that there are two air handlers and triple zone means there are three air handlers. It is best to get an air handler for each room you are trying to cool but, if you are trying to cool open areas that consist of more than one room you may be able to use one air handler just make sure the BTUs are enough to cover the square foot area of all of the rooms.

It depends on the application. They make something called a thru-the-wall unit, or a PAC (Packaged air conditioning unit). Which can incorporate a fresh air intake. But these units are mostly used in motels. They work a lot like an old window AC unit. They work really well but they are pretty ugly.

Oh and I saw someone mention Diakon, stay away from them unless you have deep pockets. They are very very expensive. Both the equipment cost and the installation cost. I just bid one of those systems and it was for 57 FCU's and the equipment cost was $685,000.00, thats almost 3 times what a standard HP system would have been. And the piping is very complicated, I bet we had 4 times a much labor as we would have in a standard line-set refrigerant piping system.

That's PTAC, guy. The T stands for "terminal". ANY unit that's self-contained is also a package unit.
