Setting up basement office

The problem is even more complicated because my office needs to be set up in the basement which is always ice cold

For the past two years I have been working extremely hard on a sizable project of mine. It is a mental health awareness plus support group that other people genuinely seem to appreciate. I cherish spending my time on it plus feeling like I am giving back to people with similar struggles. However, I have never had the environment or infrastructure to take the project extremely seriously. In fact, I always find myself working on long, arduous articles as I sit at a living room table or sofa. I decided that I finally wanted to set up a living room so I could concentrate on my work more steadily. Then, I realized that indoor air quality was going to be a sizable part of my modern work environment. At first, I thought I just needed to buy a desk plus a few pieces of technology. Then, I realized one of the most important pieces of technology was going to be a modern indoor air handling system. You see, my central heating, cooling, plus air quality control system does not work genuinely well. The house is generally fluctuating from hot to cold throughout the day plus our energy costs are nothing to be jealous of. The problem is even more complicated because my office needs to be set up in the basement which is always ice cold. The space is not affixed to the central heating, cooling, plus air quality control units. Therefore, I either need to extend the energy inefficient central heating plus cooling system all the way into the basement or I need an alternative air quality control unit… Right now, I’m looking at purchasing a gas powered fireplace or a full mini split ductless heating plus cooling system. I need to work more before I can afford either.
