If the building holds 3 units. The middle unit is humming at 10pm every night in both closets. The tenants under them have had a humid and heat problem in the apartment even running a air conditioner and air exchange for the apartment.( No change)Always feeling tired, head aches,eyes burning and sore throat. Month 10 starting so I have decided to block the bedroom air vents are plugged from the bedroom and now the apartment stays cool. On the same day vents were closed the apartment upstairs became hot and the drywall nails in ceiling have started to pop out more than the bathroom… I have complained to landlords but nothing done, also reported it to local police, they seem not to bother, or give personal opinions what the smell is.Now the man upstairs has become very aggressive towards my family for putting complaints. What should the tenant do to regain her health and her families health? Also our safety for it seems to be a family organization?

I have 2 suggestion on to protection of your renting units.
1. Place humidity counters in your walls connected to a central for you to keep track of heat and humidity. This way you are able to know of a problem. You will be able to check and act on any mold,water lines leaking and grow operations problems.
2. Place several piping tubes with several small holes along it,place up the inner wall from basement to roof. Have hose hook ups so you can place a humidity counter to it for several days it records each day and spikes of humidity,heat differences and this will allow you keep an eye on things. Also these tubes can be placed inside apartments as vents to also do testing for air quality control. Tenants don’t need to know all the compounds of pesticides,chemicals,humidity,etc.They just need to know that it is for air quality.
Just that a law should be passed so this is the new regulation for better landlords, and should be required by-law to have this testing done on regular bases or if tenant complains. Also to be filed with a government system to keep track just in case of unseen issues that may not come to light right away. Everyone will be happy and some wont know the real truth behind it. LOL
