The best solution for the HVAC unit would be to construct and enclosure around the unit itself and then treat the inside of the enclosure with soundproofing materials. The enclosure needs to be at least 8' above the noise source in order to be effective.
As far as the soundproofing materials needed, you could use the closed cell foam mat or some of the Mass Loaded Vinyl (MLV) or a combination of both. The (MLV) would staple or glue to the inside of the enclosure and then for extra protection you could glue a layer of absorbent foam over top of the vinyl. This should do the trick as far as blocking and absorbing most of the A/C noise.
Obviously the enclosure needs to be as close to the unit as possible but you must still allow adequate ventilation for the compressor. Check with the manufacturer.
If it is possible to put a canopy or covering over top of this enclosure but leaving a 2' to 3' gap between the top of the enclosure fence and this canopy (for ventilation), it would help to protect the foam from the elements. The foam is weather resistant, but will show signs of wear after years of exposure to snow and heat. The cover or canopy will increase the life of this foam tremendously.
Glen, there are other methods that could be employed, but this is the cheapest and most effective. Thanks for the post.
