This is not an ideal installation condition for an exterior condenser unit.

The surrounding grade is too high and too tight to the base of the equipment, allowing earth, stone, moisture, and runoff to remain in direct contact with the lower portion of the unit and its support surface. That is a bad long-term setup. When exterior mechanical equipment sits in conditions like this, the bottom of the cabinet and base area are more vulnerable to ongoing damp exposure, corrosion, and premature deterioration.

The better approach is to create a more suitable installation environment for the equipment itself — whether that means lowering the surrounding grade, improving drainage and clearance, or mounting the unit differently if the slope makes a ground-level installation impractical.

A lot of HVAC problems are not just equipment problems. Sometimes the site conditions are what shorten the life of the unit.
