Hey does anyone have any thoughts on if I should have my outdoor heat pump unit secured to a reinforced concrete pad? I had someone tell me the unit should be on a reinforced concrete pad with another black rubber pad on top of that. They also said there should be vibration isolators between the two. I have a Lennox 14HPX030 heat pump. I live in Greenville SC and this person was telling me that my unit needs to withstand 60 MPH winds. I think this sounds a bit silly. Any thoughts?
