Neighbour has built appliance cabinet on party wall.

Kindred74

Hi,

Our neighbour recently built a cabinet on the party wall to have their heat pump, washer and dryer in. Since then there is a constant low frequency hum in our house, which I'm assuming is their heat pump. It's gets louder when the washing machine and dryer is on, when the washing machine is spinning fast it is very disruptive. They have spent a lot of money, and are obviously reluctant to have to undo any work. The appliances are tightly squeezed in, so I'm assuming all the vibration is being transferred into the wall, which the cabinet is bolted to. It's an annoying sound, and audible even in conversation. Bar just getting ear plugs for bedtime, are there any solutions they could try? Maybe a type of insulation behind the appliances or something?

Heat pumps should be on rubber feet to dampen vibration. Maybe you can ask them to fit them to their installation

Feet won't help much if its bolted to wall as OP is suggesting

This needs to be resolved at source so you need to collect some data by a certified company and then go legal supported by medical reports for stress depression etc if they don't change it

Its akin to low level HAVANA SYNDROME
