Your air conditioning system’s outdoor compressor should be set on a concrete surface. The pad’s sizes should be large enough to accommodate all four legs of the unit. The pad should be level as well. Every refrigerating cycle will shake, wobble, and vibrate the condenser if it isn’t level. It will become even more unbalanced as a result of this. The shaking may cause excessive damage to mechanical components, detectors, and cables. Loud noises can also be caused by incorrect tightness or inadequate lubrication of the air conditioner’s moving parts.
