Research from the U.S. Department of Energy (DOE) has consistently shown about 30-40 percent of the air traveling through ductwork leaks, and if air is being pulled from somewhere, like a dirty crawlspace, it is going to effect IAQ.
Being accountable for proper airflow delivery causes a tech to examine every portion of an installation differently. Airflow is no longer assumed since test instruments now measure it. Let’s look at some of the most common obstacles to achieving a successful air balance on a residential HVAC system.
In the land of comfort, educated home owners are changing their thermal expectations from HVAC systems, and contractors are on the front line hunting for the best solutions. Regardless of ducts or pipes, the “migration” of heat takes a basic understanding of what works and what doesn’t.
This round, overhead, and porous fabric HVAC duct system distributes a large volume of air into data center cold aisles with low 400-feet-per-minute velocities that don’t upset critical equipment intake and exhaust or room return air containment balances.
Registers and grilles provide opportunities for you to easily solve comfort issues and make upgrade accessory sales that may have been overlooked previously. By understanding the impact these accessories have on HVAC systems and the air distribution in rooms, you create a win-win for you and your customers.
Depending on who you’re talking with, the phrase "green ductwork" can mean different things, though most agree it typically encompasses recycled materials, various IAQ elements, duct-sealing products, and more.
When purchasing a newly constructed home, homeowners assume all the appliances and electrical and mechanical systems will be working as they should because they’re brand new. However, with some houses, that may not be the case. If builders don’t take proper steps to cover ducts during construction, homeowners may be in for a rude awakening.
