I am having my compressor (outdoor unit) moved from the back of the house to the side of the house. I have noticed that when the unit is leveled it operates nice an quiet but as soon as it gets out of level the noise level increases.
In the old location I used thick rubber to insulate and level the compressor and that worked ok, but I am looking for pointers to any L type brackets that may have 4 leveling screws. The work will be done by a contractor, but I may want to supply a better quality L brackets ( they want to re-use the current brackets ). The type of L bracket I would love to see, is with screws that have rubber pads, that can be adjusted up or down.
