Once you’ve modified the damper of all diffusers on the concentrate on airflow, go close to and evaluate all diffusers all over again to check out if their airflow is now appropriate (what you want to accomplish).
Nevertheless, you may multiply the air velocity via the duct space to acquire the air quantity. But, It's not at all the right means of doing the air balancing work.
If you are unable to obtain a flow hood, you could possibly consider using an anemometer that includes a Exhibit with a little supporter hooked up to it. Anemometers are used to evaluate air velocity rather then air quantity or airflow in CFM or m3/hr.
Whilst Expert air duct cleansing gives one of the most thorough Answer, enthusiastic homeowners can tackle some basic servicing themselves. Nonetheless, it’s crucial to grasp the restrictions of a Do-it-yourself approach in comparison to Expert companies.

Air balancing isn't uncommon for HVAC venture engineers. Apart from, homeowners could also have to do air balancing as soon as in a few years to take care of thermal comfort and ease. So, what is HVAC air website balancing and more info How would you balance the air?
