Sounds like things are not terrible right now temp wise.
However. We won’t know for sure until you get the temp gun.
I would still consider removing the humidifier and plumbing.
See how much the temps are changing with the mist when the heat gun comes.
Consistent temps are much better than fluctuating temps.
Once you know your temps for sure, you will be able to make informed decisions.
If you want to advise after you know the temps with the temp gun, feel free.
That will also give everyone time to cam down.
After this thread, as Godzilla78 said, do your best to research more and ask less.
Check both your attitude and expectations at the door if you do post again.
Not many people get three chances.
Good luck.
