How to Tell if the AC Is Leaking Refrigerant and Needs Repair
Responsible for absorbing and releasing heat, refrigerant is central to the operation of air conditioning systems. A refrigerant leak can significantly impair the system's performance, leading to additional issues. This blog outlines the common signs of a refrigerant leak and their causes.
Frozen Evaporator Coils
Frozen evaporator coils are a common issue in HVAC systems. When a leak occurs, refrigerant levels drop, resulting in insufficient refrigerant to absorb indoor heat adequately. This decrease in system pressure causes the evaporator coil to become too cold.
Consequently, moisture in the air freezes on the coil, leading to ice build-up over time. This reduces both airflow and system efficiency, resulting in higher energy bills. Operating with frozen coils can also damage other components, such as the compressor. To fix this, a certified technician should promptly repair the leak and provide proper refrigerant recharge.
The AC Is Not Cooling Properly
If the AC system is not cooling as effectively as it used to, one potential culprit could be a refrigerant leak. Refrigerant plays a critical role in the cooling process. It circulates through the system and absorbs heat from the indoor air, transferring it outside.
When there's a leak, the refrigerant level drops, leading to several noticeable effects:
- Warmer Air from Vents: Low refrigerant levels reduce AC efficiency, leading to warmer air and difficulty cooling.
- Longer Cooling Cycles: To compensate for the reduced cooling capacity caused by a refrigerant leak, the AC may run longer or cycle on more frequently.
- Increased Energy Bills: Due to the longer and more frequent cooling cycles, the energy consumption of the AC system rises noticeably.
If there’s a leak, contact a qualified HVAC technician to diagnose and fix the problem right away. They can recharge the system with refrigerant, ensuring efficient AC operation.
Unusual Sounds
When unusual sounds such as hissing, gurgling, or bubbling come from an air conditioning system, it may signal a refrigerant leak. Here’s why these sounds might occur:
- Hissing Sounds: This sound typically occurs when refrigerant escapes from the system, especially if the leak is coming from a small hole or crack in the refrigerant lines.
- Gurgling Sounds: As the refrigerant leaks, air might enter the system, forming a mixture of air and refrigerant within the lines.
- Bubbling Sounds: The presence of air allows bubbles to form within the refrigerant, and as these bubbles circulate through the system, a bubbling noise may be heard.
When these sounds are detected, an HVAC technician must inspect the system promptly. Identifying and fixing a refrigerant leak early can prevent more serious problems and keep the indoor environment comfortable.
