My HT room is right by the heat pump unit. It's on the outside of the rear wall. I can hear it when the unit kicks in. Any ideas on how to fix this or limit it? The wall is already finished so any other way to reduce the noise I hear in the room?
Assuming that there is nothing wrong with the heat pump that is causing it to be excessively loud and that relocating the pump is not an option, you may have to install a soundproofing wall inside your room. Use something like Acoustiblok in the new wall.
Yes there's nothing wrong with it. It's not too loud and I'm sure when the system is on I won't hear much. It's just big and the fans are what I hear. I also saw something online once that you could use around the heat pump to help with the sound but wasn't sure where and if that would really help. This is not a new wall so soundproofing it would mean tearing the wall down and redoing it! Ughh I'll check out that link however.
The first step, aside from determining how much of a sound reduction is required, is to get the unit on sound isolation pads. A significant amount of noise will be conducted mechanically through the ground by the tightly coupled mechanical structures.
Also, you may want to consider line isolators - flexible connectors that will minimize the transmission of noise via the coolant lines - depending on how much noise reduction is required.
Be sure to damp these lines inside the house to prevent them from contacting rigid surfaces and transferring the energy. Suspend them and damp them with loose fill insulation pack around them.
Sorry - was thinking it was inside your basement, not outside. My bad. If it is attached to the house on a platform like they are in many areas vs sitting on a concrete pad on the ground, then some sort of isolation mechanism is in order like what SAC provided reference to.
I wonder if building an enclosure around the 3 sides and the top of the heatpump (keeping the front open) insulating with styrofoam insulation would help.:dontknow: You may also get beeter efficiacy out of it without the sun beating down on it at all but you would still need to be sure you have plenty of space around it so it does run efficiantly.:T
Well I have to do "Something". The noise is starting to annoy me. I hear it when it kicks in and unless the volume is high or there's action on I can hear it working. I wish the basement wasn't complete so I could better fix this issue. I'll be looking into the enclosure idea.
My neighbor just installed a heat pump and it points right at my house. What can I do to quiet it down? I will put up sound deadening if it would help or am I wasting my time? Their heat pump is bolted to the side of their house about 4ft above ground. Thanks Mike
If your Heat Pump is out of the house then you can use a noise barrier wall and it will protect you from the noise generated from anything. If you want you can use because I've got many benefits from using it.
