The short answer is no, your HVAC fan should not be left on all the time. There are a few reasons for this: 1.

It can shorten the lifespan of your HVAC system: Constantly running your fan can put stress on the system and cause it to break down sooner than it would otherwise. 3. It can cause unnecessary wear and tear: Running your fan all the time will just cause it to wear out faster and will require more maintenance over time.

In this case, it’s best to call a professional for help.
