1.2. Extended Cooling Intervals

Want to know how long your unit should take to cool your home? Simply put, the refrigerant’s job in the cooling process is to absorb the heat from inside your home and release it outside. When an air conditioner refrigerant leak starts to develop, the refrigerant levels will be depleted. Once the refrigerant level becomes too low, it will take longer to cool your home. Consequently, your unit will run longer and work harder than usual.

The longer cooling cycles mean your system is struggling to reach the set temperature, wasting energy and increasing wear and tear on components. According to a study by the National Institute of Standards and Technology (NIST), refrigerant leaks can reduce cooling efficiency by up to 20%.

1.3. Water Dripping

Low refrigerant levels can cause ice to form on the coils, which melts and causes water leaks. When the refrigerant level for your air conditioning system is too low, your unit will lose pressure. This can cause freezing coils, which may overflow the drain pan and spill excessive water when it melts.

Water leaks can damage your floors and walls, leading to mold growth and other structural issues. Addressing the refrigerant leak promptly can prevent further damage and maintain a healthy indoor environment.

1.4. Unusual Sounds

Hissing or gurgling sounds can indicate a refrigerant leak within your AC system. Typically, hissing sounds are caused by holes or cracks in the coils that circulate the refrigerant. While hissing noises do originate from your air conditioning unit, they can be caused by a variety of problems. If the refrigerant in your air conditioner is leaking through a relatively large hole, your system may make a louder, gurgling sound.

These sounds indicate escaping refrigerant and reduced system efficiency. Ignoring these noises can lead to compressor damage and costly repairs. Regular inspections can help catch these issues early.

1.5. Observation of Bubbles

HVAC technicians look for bubbles to find refrigerant leaks, which can be detected in the evaporator coils. Professional HVAC technicians sometimes refer to refrigerant leaks as “champagne leaks” because the hole leaking fluid can be detected by a collection of tiny bubbles in the evaporator coils.

Bubbles are a clear sign of escaping refrigerant, indicating a need for immediate repair. Allowing the leak to persist can lead to further system damage and reduced cooling capacity.

1.6. Development of Ice on Coils

A tell-tale sign of an air conditioner refrigerant leak is the formation of ice on your evaporator coils. When insufficient refrigerant levels circulate through the evaporator coils, the coils will have trouble adequately absorbing heat, which will cause the condensation on the coils to freeze.

Frozen coils reduce the system’s ability to cool your home effectively. According to the Environmental Protection Agency (EPA), maintaining proper refrigerant levels can improve AC efficiency by 5% to 10%. While ice on the evaporator coil might not seem alarming, it could result in a complete system breakdown and cause expensive repairs. Be sure to monitor your evaporator periodically, so you can see when frozen crystals form.

1.7. Warm Air Supply

One of the most obvious signs of a refrigerant leak is the lack of cold air coming from your vents. When your AC unit fails to blow cold air, check the air coming from the vents. Do this in multiple rooms to confirm the issue. If the air is not ice-cold, you probably have an HVAC refrigerant leak.

This symptom directly impacts your comfort and indicates a significant loss of cooling capacity. Addressing the leak promptly can restore your AC’s ability to cool your home effectively. CARDIAGTECH.BIZ provides the tools you need for these repairs; contact us at Whatsapp: +1 (641) 206-8880.
