My wife and I have noticed a humming noise coming from our home. We have noticed the noise louder as time is passing by.

How I can explain the noise is as if a vehicle is running and you have that low pitch noise from the engine running in the background. This is irritating but more bothersome we are worried it could be an electrical issue.

We are renting the home and the Landlord does not fix anything small so I could only imagine the fit he will throw if he finds out that the home has a severe electrical issue.

Can anyone give me clues on how to figure out if this is an electrical issue or what.

I too have experienced a low frequency hum throughout my house. It was driving me nuts. My wife couldn't hear it, only me. I traced it down to my vent stack pipes on my roof. I put a couple of 90 degree elbows on each vent to turn the outlet toward the roof. The low droning hum went away. I'm not saying that this will fix the problem that you are having but, you might give it a try.
