Our bedroom is right above where the furnace is in our rented apartment. The furnace below makes a lot of noise, especially a rattling noise. Landlord is refusing to take any actions on it saying it is normal so I am trying to find some practical solutions.
This is what the device looks like: (it may not be a furnace, I do not know..)
Yesterday when it was working I again woke up due to noise and went downstairs and did a video recording. As seen if I push it with a stick, the rattling noise goes away (not always, but it does if I push hard enough): https://streamable.com/9uiyhd
Are there any practical solutions I can apply to reduce this noise? I am willing to pay a few hundred dollars if needed myself..
Can you be as specific as you can for the tools I can use, I have zero experience in home improvement / maintenance. I am thinking about putting rocks on it (I do not know how yet), would that help?
