Bearing the heat is something we cannot imagine and it is not a good thing. If you find it hard to centrally air condition your house due financial constraints then a mini split air conditioner will be a good option as they are affordable and also can provide you with a comfortable living space. Since a mini split unit does not require any duct work it is easier to install and is budget friendly. Such units consume lesser energy hence you will not have to pay huge amount on energy bill especially if you have installed a 4 or 5 star rated unit. Moreover you can control the areas where you want to cool hence there is no unwanted cooling of any room. Since it is a ductless unit it can cool only a smaller area. If you want to control the temperature of your entire house then a ductless unit will be a better choice.
A split unit has two main components the inside unit and outside unit. The compressor is assembled in the outside unit hence making it quite while operating from inside. The inside unit is connected to the outside unit with a copper tubing that runs from the inside unit through a small hole made on the interior wall where it is installed. Usually it is made to function to cool the room where it is installed. The air filters of a ductless units are stronger and can do better air filtration by removing dust and other allergens from the air more effectively.
