Different hacks make your HVAC system run more efficiently and save you a lot of cash that would otherwise be spent on paying energy bills. One of the things your HVAC technician will advise you to do is to focus on insulation. This tends to reduce the energy costs by 10 to 30 percent, meaning that you pay less for the same comfort level, if not better. With this in mind, wrapping your ductwork indeed has the potential of helping minimize condensation, especially on residential systems. First things, though, you need to understand the condensation process that takes place in your HVAC system. These are the tiny beads of water that form on your ductwork. It happens for various reasons, including when there is a significant temperature difference between the cool air inside the AC ducts and warm air in the surrounding environment. Water vapor tends to cool and collect on the surrounding ductwork surface. This effect worsens during hot summers when there is a vast difference. Covering the ductwork helps reduce the difference between the internal and external environment, which consequently reduces the condensation process. Condensation of air ducts can also be problematic to the air conditioning unit. As the moisture accumulates over time, it tends to attract mold and can easily cause a quality reduction. It may lead to structural strain and damages, especially when water starts draining to the ceiling. Fortunately, several remedies apply to this issue, most of which professional HVAC contractors can easily handle. Check out potential mechanical problems as they trigger such issues. Working with any licensed HVAC professional is advisable in such cases.
