Why do you get 24 volts on my HVAC air handler when the fuse is out and 7 put back in?

You should not be getting 24 volts on your HVAC air handler when the fuse is out, and you should get 24 volts when the fuse is put back in. If this is happening, you may have a problem with your HVAC system and should contact a qualified technician to diagnose and fix the issue.
