Are you looking to add air conditioning to your home but don't have the ductwork for central air conditioning? If so, it will help to know the differences between these three types of air conditioners.
Split Air Conditioning
What makes a split system air conditioner unique is that there are two components of the system. The compressor is located outside of your house while the blower is located in the house. It works much like a traditional air conditioner, with air cooled by refrigerant flowing into the home to remove heat from the air before moving back out of the home to flow through the compressor again. The benefit is that the split system can be retrofitted into an existing home with ease.
A split air conditioner is not going to cool down your whole home, but it can provide cool air in the places that you need it. It also uses a lot of electricity when you consider the square footage that the unit cools. It may not be a practical solution to cool your entire home.
Exhaust Tube Air Conditioning
An exhaust tube AC system is an entirely portable unit that can be easily moved to any room of your home. Instead of mounting the air conditioner in the window, which can be problematic for some people, it uses an exhaust tube that goes through a window for the unit's exhaust.
Many people love this type of unit because of its portability and how it can effectively cool a large space. However, it is not fully automated. It is common for these units to collect the condensation in a tank within the unit. The unit will shut down when the tank becomes too full, which will require you to empty the condensation tank. This does not make the unit ideal for an elderly person living on their own or someone that is disabled.
An evaporative cooler works by having a fan blow hot air through an evaporator pad that is covered with water. It is able to produce enough cool air to cool off a room without using refrigerant. It's considered a more energy-efficient way to cool off your home since electricity is mainly used to run the fan. However, there are two drawbacks to this method. Evaporative cooling introduces more humidity to the air, as well as not offering much in terms of temperature control.
