I work from home in a small office in Sydney, and the April weather is hard to manage. It is cold when I start work, but by noon the sun hits my window, and the room becomes very warm. I cannot focus when I am constantly changing from a sweater to a fan, so I need to handle both cold and heat. I found some portable AC rental units, like the 4.0kW reverse cycle models. I do not know if renting for $110 a week is worth it or if these units make too much noise for video calls. Are there cheaper or free things to do, like using thick curtains?
