Just had a new Rheem RPMD 3 ton heatpump installed adjacent to my screened porch. It's quieter than my old unit but I'm hoping that with the addition of a sound blanket on the compressor that I might be able to get it even quieter. I realize that the majority of the noise is fan noise but the hum/drone of the compressor can also be heard.

Any sugestions regarding "factory" sound blanket vs. aftermarket sound blankets for the scroll? If so what do you recommend.

Also, do you think the sound blanket will really make any difference on the Rheem Heatpump or am I just throwing away money? Any real world experience with this brand with and without a sound blanket?
