Low refrigerant levels in an air conditioning system significantly impact its performance, primarily leading to reduced cooling capacity. Refrigerant is essential for absorbing heat from the indoor air and transferring it outside. When the refrigerant level is low, the system lacks sufficient material to effectively absorb and remove heat, resulting in a diminished ability to cool the air within the space.

As the refrigerant circulates through the evaporator coil, it changes from a low-pressure gas to a high-pressure gas, allowing for the absorption of indoor heat. With inadequate refrigerant, the pressure drops, and the evaporator coil may not get cold enough, diminishing its capacity to cool the air. This directly leads to warmer indoor temperatures and inconsistent cooling, making it crucial to maintain the correct refrigerant levels for optimal system performance.

Higher efficiency, improved air filtration, or enhanced airflow are not outcomes of low refrigerant levels. Instead, low refrigerant primarily reduces the system's effectiveness in cooling and can lead to complications, such as increased energy consumption and potential system damage if not addressed promptly.
