A properly functioning air conditioner is essential for staying comfortable during Charleston’s hot, humid summers. But if your cooling system is losing its power, the cause could be a refrigerant leak—a serious issue that requires professional attention. Refrigerant isn’t just what keeps your home cool; it’s a crucial part of your system’s operation. Ignoring a leak can lead to higher energy bills, poor cooling, and even permanent damage to your AC unit.

In this blog, we’ll explore how to spot the signs and why calling a professional Isle of Palms AC repair service is the safest route.

1. Your AC Isn’t Cooling Like It Used To

One of the most apparent signs of a refrigerant leak is reduced cooling performance. If your air conditioning system is running but the air coming out of the vents isn’t as cold as it should be—or if some rooms are warmer than others—it could indicate low refrigerant levels.

2. Ice or Frost on the AC Unit

Low refrigerant can cause the evaporator coil to become too cold, leading to ice buildup on the coil or refrigerant lines. Ice formation is a serious warning sign that your system isn’t functioning correctly. Continuing to run the unit can damage the compressor, which is one of the most expensive components to replace.

3. Hissing or Bubbling Sounds

Refrigerant leaks are sometimes audible. A hissing or bubbling noise near your indoor unit or along refrigerant lines can indicate gas escaping under pressure. Any unusual sounds should be inspected immediately.

4. Higher Energy Bills

If your air conditioner has to work harder to reach the desired temperature, it uses more electricity. A noticeable spike in your energy bills—without a change in usage—can be a sign that your HVAC system is struggling due to low refrigerant levels.

5. Moisture or Leaks Around the AC Unit

Refrigerant leaks can sometimes appear as pooling liquid or unusual moisture near your air handler or outside unit. While not all leaks are visible, any unexplained moisture should be checked by a professional air conditioner repair team.

Why You Should Call a Professional HVAC Service

Refrigerant is not a substance to handle on your own. It’s regulated, requires special equipment to repair, and improper handling can be dangerous to both you and the environment. Attempting a DIY fix can also void warranties and cause further damage to your AC system.

  • Accurately locate the leak
  • Safely recharge the refrigerant
