Knowing if a HVAC system or fan is working efficiently for your customer is important and can be determined by the airflow it produces. Here are several techniques to measure airflow in an HVAC system.
Let’s start with the basics. First, airflow is usually measured in cubic feet per minute, known as CFM. We understand that this may seem a little overwhelming at first, but when using a device, it is actually pretty painless. An HVAC system or fan will list the recommended airflow in the owner’s manual, so you can compare the readings to that.
