The Different Types of Air Conditioning Systems

Comfort is a luxury that every human being craves. Whether it’s at home, on the road or in the office, we always strive to make sure that we are comfortable. When it’s hot outside, one way of achieving this is through air conditioning. Commonly interpreted by many as the cooling of air, air conditioning is more about altering the properties of air, primarily temperature and humidity, in order to achieve comfortable indoor air quality. Here are the major types of air conditioners that you can use at home:


Window Unit System 


This is a self-contained air conditioner that is placed in a window or through a hole in an exterior wall. Generally, it ejects hot air through one end and blows in cool air through the other. This is achieved by two fans. One blows over the evaporator to draw heat from the interior and the other blows cooler outside air over the condenser.  Its benefits include:


  • Easy installation
  • Good overall affordability
  • Low energy costs
  • Room-by-room control


Packaged Terminal Air Conditioner (PTAC)/ Wall-Split System 


This breaks the air conditioning system into two terminal units, the evaporative unit on the interior and the condensing unit on the exterior, with an opening passing through the wall and connecting them. Its benefits include:


  • Easy installation
  • Room-by-room temperature control
  • Low purchase cost per unit
  • Energy efficient


Mini-Split (Ductless) System 


This combines an outside compressor with one or more indoor air-handling units. The units are mounted high on the wall and have blowers attached. Tubing that allows refrigerant passage connects the units with the outside compressor.  Its benefits include:


  • Efficient heating and cooling
  • Easy, low-cost installation
  • Quiet operation
  • Easy to operate


Central (Ducted) System 


This is a whole-house air conditioner. It uses a heat exchanger that is placed inside the central AC unit of the forced air heating system which is then used to distribute chilled air through the building.  Its benefits include:


  • Whole-building temperature control
  • Even air distribution
  • Quiet operation
  • Easy operation

    Wow, I never would have known there are so many different types of air conditioning systems. It’s good to know that there are so many different options, when looking to put an air conditioning system. My husband and I are building a house, and we will have to put an A/C unit in. After reading this, I think that a central system would be really beneficial. Like you said, that is a whole-house unit.

    I have been looking into finding an affordable way to keep my house cool during the summer. The house is pretty old and never really had air conditioning in it. It’s interesting that with terminal air conditioners it is broken into two different units for evaporative and condensing. I will have to look into them more before I make a decision.

    I appreciate the information on the different types of air conditioning systems. I would imagine that there are a lot of choices when it comes to AC units and it can be a tough decision when it comes to which one is best for you. My mom has been in need of a new AC unit in her home, I will be sure to share this information with her.
