Residential duct work the different types and materials used.
There are many varieties of duct work styles and materials used over the years but the basic idea has always remained the same. It creates an enclosed system that allows for air to be distributed.
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.These all sheet metal duct work systems are the most robust and durable and are not commonly found on more modern homes other than high end custom homes. While being the most durable and robust system of duct work what it is usually lacking in older homes is usually insulation.
Most older ducts were not insulated either on the inside or the outside due to the added costs. This provides homeowners with sheet metal ducts a great opportunity for energy savings.
As can be seen from the diagram flexible ducts are used normally in any unconditioned space such as an attic or crawl space. Any ducts inside the home itself where the space temperature is being conditioned the dust work does not require insulation by code or energy standards. However there are energy savings to be gained from insulating this duct but the return on the investment for a residential structure limits this to high end custom homes.
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.More often these days on tract homes or any affordable home you will find that the maximum extent of the sheet metal used in a home is limited to the equipment plenums (the sheet metal boxes connected at the return inlet and supply outlet of
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.This method usually works fine if it is implemented and designed correctly but normally on most homes what works best or usually becomes necessary in many
cases is to install small dampers inside the ducts to adjust the amount of air flow to each 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.

  What
should I Look for Before I call for services on my air conditioning
system? The number one issue we find on air conditioning systems is
clogged filters. First look to see if your air filter is clean and not
clogged up, if it is clogged change the air filter and try your system
again but keep in mind with the air conditioning system running with a
clogged air filter you could have also iced up your indoor coil due to
low air flow.

  Why
does my Air Conditioning run all day in hot weather? Assuming this is
not a new symptom... this is a common complaint and can be attributed to
two possible things. The first is that your system may have been
designed correctly to meet the latest energy codes to perform at the
highest efficiency. The other possibility is that it was not designed at
all or was not sized properly in the first place. |
  Things you can do to maintain your air conditioning system. You can keep the outdoor air conditioner clean. You can
vacuum out the inside of the unit and get all those leaves and stuff
out. On most units you can gain access through the service panel. Be
sure the power is off before opening the panel. Be careful not to knock
off any wires and do not hit the coil as you will cause permanent
damage.

  In
the case of the thermostat calling for cooling the thermostat switches
on the power from the “R” or in some cases the “RC” terminal which is
the 24 volt power source to the “Y” terminal on the thermostat which is
in essence the call for cooling. These terminals are located on the back
or on the wall mounted face plate of the thermostat. All the wires
connected to the thermostat will usually always go directly to the
furnace and another set of wires will then go out to the outdoor air... |
