Installing an air condenser on ICF foundation
We are in the process of finishing a large addition to our home. The basement of the addition has ICF for the foundation. The HVAC guys were asked to install the air condenser on the ICF part of the foundation. We were shocked when we came home to see that they had instead installed the air condenser with metal supports through the old part of our standard foundationn (3 feet away from where we had asked). This places the air condenser right under our kitchen window and blocks the light partly from the basement bathroom window. Their explanation for why they had not installed it in our chosen location on the ICF part of the foundation, was the ICF styrofoam would have not allowed a strong contact point for the metal braces to meet the wall, and that this connection would have become loose over time as the condenser unit vibrated.
Have you any suggestions for how we could get it re-installed in the ICF part of the foundation. Should we be looking at a concrete support pad to mount it on rather than the metal brackets?
