In a previous column, I discussed some tough lessons I learned from measuring airflow with an air-balancing hood. From those lessons came an opportunity to offer a unique product that totally separated us from the competition. That product was an airflow upgrade — the process of surgically renovating and correcting duct-system defects through testing.
It’s a well-recognized fact that ducted HVAC equipment efficiency and performance are directly connected to the duct system. Through studies conducted by the National Comfort Institute (NCI), we have learned the average airflow from the typical system is found to be more than 30 percent less than most manufacturer’s recommended specifications.
