HVAC Ductwork Basics

If you’re about to install a new HVAC system in your magnewsworld home, you’ll want to know a few basics about ductwork and how it works. Proper airflow is vital to a functioning HVAC system. Incorrectly designed ducts can reduce indoor air quality and increase energy bills.

A good duct design numega begins with a load calculation. For this, you can use the Manual J software produced by the Air Conditioning Contractors Of America (ACCA). Manual J software uses the thermal characteristics of each room as well as the climate to determine a heating and cooling load. Once you know how much air each craftymagazines room needs, you can use a duct calculator to determine the proper duct size.

Ducts also need to be properly sealed to prevent air leaks and thermal gain/loss. Air leakage lowers indoor comfort and vitlink increases monthly operating costs. A professional duct sealer can seal your ducts to restore them to their optimum efficiency. Thermal gain/loss can also affect the efficiency of your heating and cooling systems. Thermal loss/gain can occur when ducts are exposed to extreme temperatures. In most cases, insulating these ducts will solve this issue.

Ducts come in a variety of materials. They may be justspine rectangular or cylindrical in shape. They may not be insulated. The most popular types are the sheet metal type, which you’ve probably seen in action movies. These are made of galvanized steel or aluminum and are relatively easy to install. In addition, they are also the least likely to harbor harmful mold growth.
