Following certain measures like closing the external doors and also the windows can reduce costs.

Air conditioner systems

Portable split system- this system is the ideal choice for rooms of size 35 square meters. It can be bought at $800 to $3000. This portable split system are usually limited capacity units that have different indoor and outdoor units.
