Building a condo from scratch is a long process. There are so much to choose from & so various decisions to make when developing a condo into a home. From pouring the foundation to putting up the wood that ultimately designs the house, it is one of the few steps where you can visually see a condo coming together. Once the condo is up with drywall, doors, windows & a roof it becomes more fun for me. I like to pick out the paint colors, appliances & new decor. I will let the businesss do the electrical & HVAC work. The electrician came the other afternoon to complete the electrical work. That is all done & now there’s electricity in our home. The HVAC serviceman came to my condo this week to discuss heating & cooling options. She brought up HVAC duct & showed me pictures of other houses with weird types of HVAC duct. I didn’t realize that there were other materials that were used to supply & return hot & chilly air. Some materials that I saw were building cavities that were made out of wood & wallboard inner surfaces that supply certainly little leakage. Another material was flexible non-metallic ducts. These ducts are flexible & are mainly installed in attics or slim locales. One of the possibilities that my associate and I were interested in was the HVAC duct made out of sheet metal that is made out of galvanized steel. This type of HVAC duct can sometimes leak where sections can join. The other option my associate and I saw was fiberglass duct board that is used to feed smaller ducts.
