What can low refrigerant levels in a system lead to?

Low refrigerant levels in an HVAC system can lead to reduced cooling efficiency and potential compressor damage due to several factors. Refrigerant is vital for transferring heat; when levels are insufficient, the system struggles to absorb heat from the indoor environment. This leads to poor cooling performance, often resulting in higher temperatures and discomfort in the conditioned space.

Additionally, when refrigerant levels drop significantly, the compressor, which is responsible for pressurizing and circulating the refrigerant, can run hotter than normal. This overheating can cause wear and tear on the compressor components, potentially leading to premature failure. Thus, maintaining proper refrigerant levels is crucial for both the efficiency of the cooling process and the longevity of the HVAC system.
