What is Pressure Drop in HVAC Systems?

Everything You Need to Know Explained Simply

If you’re an HVAC technician, or even if you just own your own home, then you’ve probably heard the term “MERV 13 filter pressure drop” thrown around a lot. But what does it actually mean?

Pressure drop is the decrease in air pressure that occurs when air flows through an HVAC system. This can be caused by a variety of factors, including the type of ductwork, the size of the ducts, and the length of the run. In addition, any bends or turns in the ductwork will also cause a pressure drop. The most common way to measure pressure drop is with a manometer, which is simply a device that measures pressure.

Once you know the cause of your pressure drop, there are a few ways to correct it. One way is to simply increase the size of your ductwork. Another option is to use less rigid materials for your ductwork, such as flex duct or spiral duct. Finally, you can also add dampers to your ductwork to help control the airflow and reduce pressure drop.

Also, keep in mind that pressure drop is not always a bad thing! In fact, it’s often necessary in order to maintain proper airflow throughout your HVAC system. If you have any questions about pressure drop or how to correct it, be sure to ask a professional HVAC technician. They will be able to help you troubleshoot the problem and find the best solution for your home or business.

For example, if you have an HVAC system with a blower that’s not working properly, the pressure drop can actually help to diagnose the problem. That’s because when there’s a pressure drop, it means that air is not flowing through the system correctly. By troubleshooting the pressure drop, you can often find the root cause of the problem and get your HVAC system up and running again in no time!
