What is the impact of refrigerant leaks on HVAC systems?

Refrigerant leaks in HVAC systems primarily lead to a potential system breakdown. When refrigerant levels drop due to leaks, the system cannot properly cool or heat the air as intended. This results in increased strain on the remaining components, as the system attempts to maintain performance with insufficient refrigerant. Over time, this strain can cause mechanical failures, leading to a complete breakdown of the system, requiring costly repairs or replacements.

Furthermore, refrigerant is essential for the heat exchange process that keeps the system functioning efficiently. A significant loss of refrigerant also leads to poor indoor air quality and can increase energy costs due to the system working harder than necessary. In contrast, the other options suggest benefits that would not materialize in the presence of leaks. Therefore, addressing refrigerant leaks promptly is crucial for maintaining the efficiency and reliability of HVAC systems.
