Inefficiency is a major concern when it comes to an unlevel AC unit. Lack of lubrication due to an uneven unit can result in increased wear and tear on the system’s moving parts, leading to premature failure of key components such as the compressor and fan motor. These failures can require costly repairs or replacement.

Overheating is another consequence of an unlevel AC unit. When the unit is not level, it can restrict airflow, preventing the system from effectively dissipating heat. As a result, the AC unit has to work harder, leading to increased energy consumption and reduced overall efficiency.

Additionally, an unlevel AC unit can experience reduced efficiency due to poor refrigerant flow. When the unit is not level, refrigerant may pool in certain areas, preventing it from circulating properly throughout the system. This can lead to inefficient cooling and an overall decrease in performance.

4. Draining Problems Caused By Unlevel Surface: Water Pooling, Increased Humidity, Contaminant Growth, And Coil Damage

An unlevel surface beneath the AC unit can lead to draining problems with significant consequences. When the AC unit is not level, water can pool around the base, especially during periods of heavy rainfall or when the unit is in defrost mode. This pooling of water can result in increased humidity levels and provide an ideal breeding ground for mold, mildew, and other harmful contaminants.

Furthermore, the pooling water can cause damage to the evaporator coil, which is responsible for removing heat and humidity from the indoor air. If the coil is submerged in water for prolonged periods, it can lead to corrosion and reduced cooling efficiency.
