Is my hvac fan supposed to be always on?
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 lead to increased energy bills: If your fan is running constantly, it is going to use more energy and therefore increase your energy bill. 2. 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.

If the fan switch position isn’t the issue, it’s possible there’s a problem with the limit switch, the fan relay, or the control board keeping the fan running when it shouldn’t. In this case, it’s best to call a professional for help.

How can I prevent my hvac fan from not turning off in the future?
