Breaking lease because of noise
I moved into an 8-plex recently. The apartment I moved into smelled strongly of smoke, which the landlord didn't disclose to me at the time of signing. He offered me another unit in the building, which I agreed to. Unfortunately, there is a relatively loud mechanical noise emanating from the vents due to the proximity of this unit to the furnace for the building. This noise is 24/7, and not something that I can comfortably live with. The property manager said they've deployed someone to 'look at it' as she agreed (in email) that it was too loud. I'm not hopeful that the landlord will fork out the money to fix this issue in a timely fashion, if at all. Do I have grounds to break the lease if the landlord does not fix this and does not agree to me breaking the lease?
