Ductwork – The Courier of Warm and Cool Air
Most of the homes across the country contain heating and cooling ductwork in some form or fashion. Whether the ducts are in the ceiling, in the basement, or under the floor. The ductwork conveys warm or cold air depending on the season. There are many types of ductwork, but the main two are rigid duct or flexible duct. Both types are usually installed and maintained by professional hvac companies like Atlanta Air Conditioning Repair.
The rigid duct is usually the main trunk line that runs throughout the house, and it is normally about 2 foot in width by 2 foot in depth, although the sizes of width and depth can change vastly depending on the structure. Coming off the trunk lines are lines known as flexible ducts. Flexible ducts are heavy plastic that surround a metal coil. This coil is a large coil that resembles a large spring like device. This enables the plastic to stay semi-rigid under all weather conditions. On the outside of the plastic is insulation. This is to conserve as much energy as possible as the air travels through the duct.
Flexible ducts come off the main truck line and go to different room vents in the house. When you put your foot down on a metal vent in the bedroom, for instance, you feel warm (or cool) air because of the flexible duct attached to the vent.
Most rigid duct work is custom make by your heating and air conditioning professional. Precise measurement are taken beneath the floor, or up in the attic. Then the ductwork is made at the professional’s office; brought to the site and assembled as measured. The rigid duct work is also insulated.
Finally the duct work is fitted to your central heat and air conditioning unit or units. The thermostat is installed and the duct work keeps every room in your house warm in the winter or cool in the summer.
