Not able to work from home

Hey Everyone! I am currently working from 2BHK home and facing multiple issues to build focus in my work. We have only 1 AC so my Mom and Dad (works from home as well) are always in the same room where I work. I have asked my dad to buy another AC but he has already refused me. Similarly, I can't move to another room because that is more spoilt than my original one having access to balcony where maid washes utensils and a washing machine is present. What can I do?
