When I was a young contractor, I was still learning a whole lot about building codes. Even though I’ve been a contractor for nearly ten years now, I still have to look up a lot of the building codes and violations. I’m not certainly particular when you have to apply for permits, so I often consult the building codes manual. I know that Intercity most of the building codes talk about the HVAC system. What did they talk about Central A/C, or the cooling idea and heat pump, there has to be a heating and cooling system in the design of every building. I know it’s impossible to live in our home without a great working Heating and cooling system, especially because we live in a southern town. Some people pass out from all of the heat in the summertime. All the buildings within our city are equipped with a wonderful HVAC system, and even some of the buildings have Zone control systems. Most of the buildings downtown are very high, so the windows never open. If it wasn’t for a great HVAC system, the indoor air quality would be poor. I used to have an aunt and uncle who lived further south, and my siblings and I would visit often. They didn’t have an HVAC system in the house, and we were very miserable during the day. It’s taken me a while, but I know the buildings codes regarding the HVAC systems, more than any other items in the laws. The laws for our A/C help keep all the public buildings in great condition.
