There is one in the kitchen, living room, bedroom and bathroom
Growing up in the North was wonderful! The drastic winters made heating an absolute necessity though. As a joke I would tell the southern visitors I didn’t use heating in the house at night. I told them to bundle up for the cold. In reality, the heating as well as cooling industry is a big trade up north. The houses are always in need of a heating service, anyone who knows about HVAC or anyone with half a brain should go into the field. In retrospect down south, folks have an immense Air conditioning need. If the cooling system goes out, a HVAC contractor is called ASAP. I had a vacation home in the north that always needed some repairs. The house was built in the late 1700s. So finding someone who knew about the older homes and HVAC units was always interesting. I called a lot of professionals who knew how to work on those units. Repairs as well as flipping homes is a good extra income. I do that on the side and call the same HVAC company to help me. My current home in the south uses several cooling units. There is one in the kitchen, living room, bedroom and bathroom. HVAC is one of the biggest corporations that make money in the south. When it is 100 degrees out, everyone is thinking about their cooling system. Everybody either wants to buy a new one, get repairs on their current one or has service needed to ensure their unit lasts.
