Pad for Heat Pump Condenser
I’m planning to have a heat pump (ducted heat pump) installed soon.
my HVAC installer wants to put in a plastic (might be rubber, something like that) pad under the outdoor unit.
I talked to another person who seemed to think that was nuts–ALWAYS use a concrete pad.
But a couple of quick searches yields the fact that a concrete pad has it’s own problems: could tilt or crack if not built right, also doesn’t absorb sound the same way so might end up being noisier.
I like to find the “right” answer, but in this case, is there a preferred approach?
Or just two methods that each have their pros & cons?
If I provide a tamped gravel base for a rubber or plastic pad, is that just as good as a concrete base?
