Ignoring or delaying repairs of refrigerant leaks in HVAC systems can have significant consequences, including reduced system performance and efficiency, increased energy consumption, and potential damage to components. Additionally, refrigerant leaks can lead to environmental harm, as refrigerants can contribute to ozone depletion and climate change. Delaying repairs can also lead to more extensive and costly repairs down the line, as well as potential safety hazards. It is essential to address refrigerant leaks promptly to minimize these risks.
