There is a formula that successful contractors use to answer such questions and generate customer interest in duct upgrades. Their approach focuses on the facts about what an HVAC system is doing — they don’t share opinions or use smoke and mirrors.
Featuring a direct-drive motor, this fan has 73 airflow positions and a number of speeds to provide users with circulation whether it’s down an aisle or assembly line, around obstructions, or in spaces with low-hanging ceilings.
When space restrictions prevent the use of in-line duct fans, this product can be as little as 4 inches, providing room to connect appropriate ductwork.
The NEWS again teamed up with AHRI to produce an eBook to help contractors learn about a specific technology — ductless systems. In this book, you will learn how to promote the advantages of ductless, learn about training options, and also read about real world examples of where ductless was the right technology for a specific job.
The good news is that once you measure static pressure, you can estimate fan airflow in less than 30 seconds with the right information. Once technicians understand that static pressure testing gets them to fan airflow, they will see why it is important to measure it on every call.
From homes and apartments to office buildings, hospitals, and schools, the average American spends 87 percent of their life indoors — and another 6 percent in enclosed vehicles. That means for the overwhelming majority of Americans, the air entering their bodies every day is directly impacted by the buildings that make up the environment.
You might wonder, “Why can’t I just use a duct calculator and tape measure to identify duct repairs?” You could, but that means making a lot of assumptions and wasting valuable time.
Ductwork is a mandatory comfort delivery system. In fact, the only thing optional about it is whether or not HVAC contractors make their own fittings and duct runs.
Although ductwork doesn’t require quite as much maintenance as other HVAC equipment does, there are steps to be taken to ensure its longevity, safety, and efficient operation.
Following are four examples — a kosher wine shipping center, a chiller plant in a marine research lab, a community pool, and a 10th-floor medical office retrofit — that illustrate just how creative high-efficiency products can be when it comes to unique solutions for everyday issues.
