The job of an HVAC ductwork system is to provide you relief with cool air during summer and warm air during the winter seasons. Understanding the importance of air duct systems in your homes is crucial because they are the only reasons behind the air environment in your homes.
If you have not installed a duct system in your home yet and are confused about it then duct takeoff services can help you throughout. You will find valuable insights no matter if you are a homeowner, a contractor, or a builder. Moreover, there are also potential risks associated with the HVAC ductwork, such as delays due to material shortages, increased material costs, unexpected labor costs, and improper adjustments. Therefore construction takeoff services can help you in effective risk management in this case.
What are Ducts in HVAC?
HVAC ducts are conduits or passages to deliver and remove air, in short they control air conditioning inside of your house. For example:
- Air Supply
- Air Return
- Exhaust Air
HVAC ducts also supply ventilation air as a part of air supply. A duct system is also called ductwork. The Duct system, used in air heating and air cooling your home, is a collection of tubes that distributes the heated or cooled air to the various rooms. This system can make a big difference in both the cost and the effectiveness of heating and cooling the home.
What are the types of HVAC ducts?
There are four primary types of HVAC ductwork. These ductwork types have their specific requirements in different fields. These are:
- Metal Sheet Ductwork
- Flexible Ductwork
- Fiberglass Ductwork
- Fiberboard Ductwork
Moreover, there are three common classifications of ducts – conditioned air ducts, recirculating-air ducts, and fresh-air ducts.
In residential homes, mostly metal sheets(round & rectangular) ducts are made of galvanized metal sheets or aluminium. These are the most durable and less costly.
Best materials for HVAC Ductwork
The metal sheet ducts come further in two types of materials; the galvanized steel and aluminum sheets. Both the materials have hard surfaces and are least likely to be mold because they are not porous. These metal sheets are condesable due to air and metal contact. Therefore metal sheets need to be insulated from outside.
On the other hand, the flexible duct or a flex duct is an air conditioning duct system which is composed of grills and registers. A flex duct is mostly mounted in commercial buildings’ ceilings and walls. The fiberglass and fiberboard ducts have porous materials and are often more expensive as compared to sheet ductwork and flex ductwork.
The fiberglass and fiberboard ductworks are more likely to get mold due to less harder surface. So, they need to be extra protected from damage.
Accurate estimations of HVAC ductwork is crucial in overall budgeting of the construction projects. Construction estimating companies create a detailed list of materials required for HVAC ductwork. This is the key part of these estimating services, which ensures that overall necessary components are accounted for and budgeted.
Why Insulation required for ductwork?
One big problem with sheet ducts is heat loss through the walls of the duct. This heat loss is an inevitable drain on the HVAC duct system. This can also cause more energy consumption as well. So proper insulations on the outside of the sheets can minimize the heat loss and also save energy. Moreover the metal is more likely to be condensed so proper insulations are necessary for metal HVAC duct systems.

If these metal ducts are not insulated from outside then they can produce potential problems such as heat loss and more energy consumption.
Best HVAC duct insulation
The fiberglass duct board is by far the most effective. Best fiberglass duct services include formaldehyde-free insulation that has acrylic coatings. This coating will help the glass fibers to stay away from airstream and excess noise coming from your home. Moreover, fiberglass ducts increase the air quality by 15 times as compared to simple sheet ductworks.
Conclusion
So, in a nutshell, it recycles air from each room in your home. Warm air travels through a specific set of ducts (called a supply duct), and once cooled down, it travels back to the vents through another set of ducts (called a return duct). Estimation companies in USA consider the energy efficiency of HVAC systems during the estimation process. They focus on several key factors such as material selection, system design, equipment efficiency such as SEER and EER, sizing of HVAC, sustainability standards, and life cycle costs.
