I have been using the spare bedroom for a home office for ten years now.
Every winter, I drag my laptop out of the office and put it on the kitchen bar so I can work without freezing to death.
When the weather warms up enough that I can be comfortable again, I move back to my office. When summer arrives and the sun beats in through the window, warming the room up into the nineties, I once again drag my laptop out into the kitchen. I was tired of this game and I was now complaining. Every winter I would beg him to put some kind of heating into that room so I could work comfortably and efficiently. He would just growl at me. Every summer I would complain about how hot it was in that room and how I wanted air conditioning, and he would growl at me. Ten years later, I had found out about a ductless HVAC system. I found out that two people could easily install a ductless HVAC system, and I saved the money to purchase one. I talked to my son who was now an HVAC technician. He told me which ductless HVAC system was best for the space I had. He even told me he would have his friend come over, and for just the cost of a steak dinner, they would install my ductless HVAC system for me. He wanted to know what his dad thought, and I growled. He knew what that meant. The weekend my husband went fishing with his brother, my office had heating and air conditioning installed.
