Replacing brakes in car, while being really cold in shop and no furnace

My boyfriend owns a auto body shop in our town.

He gets a lot of calls from people and is always busy during the week.

Basically he is on call all of the time. We were enjoying our time together on the weekend when he received a call from a friend. His breaks needed to be completely replaced. So since I was with him and didn’t have my car I had to tag along. It was in the middle of winter and he had no heat! I knew that this was going to be at least 2 hours of sitting in the cold. I told my boyfriend that he needed to go to our local HVAC provider and talk to them about installing a heating and cooling system. I don’t think I could ever go back to the shop again during the winter time just because of how cold I was. There came a point where I asked if I could have the keys to his car so I could sit in his car and turn on the heater. Also I feel like he would even work better if there some kind of he and his auto body shop. I even told that there are electric portable heaters that he can I don’t think I could ever go back to the shop again during the winter time just because of how cold I was.

It may cost a lot on his electricity bill each month but it will allow some form of heat to circulate in his shop.
