Duct Work in a Typical Home. Duct work on older homes usually consists of mostly sheet metal ducts fabricated from sheets of galvanized steel to various sizes as required for a particular system and air flow requirements.
More modern homes use a combination of sheet metal and flexible insulated duct, the use of the flexible insulated duct usually increases substantially as the cost of the new home itself gets cheaper. These variances in overall quality usually do effect a home's value after the first purchase however.
the equipment) which normally extend no further than a few feet inside the crawl space or attic and maybe sheet metal duct work between floors or in walls. After that you get a giant octopus or spider legs of flexible insulated duct to each supply register.
One last type of duct work utilized today is usually called Duct Board, this type of duct work is simply made of fiberglass insulation usually sandwiched between protective layers of a type of fabric or foil. While not structurally very strong and while being prone to damage this type of less commonly used duct is highly efficient for energy consumption. Drawbacks are the same for any duct work with exposed fabric or insulation on the inside, which is the fact that the fibers collect dust and debris and is nearly impossible to clean properly.ASI's HVAC and Home Improvement Articles HVAC Contractor Air Conditioning Refrigerant Rip Off One of the more common things we see are air conditioning systems that have been overcharged with refrigerant.
