AC Refrigerant Leak in Fort Myers, FL Signs, Causes & What to Do
In Fort Myers and Cape Coral, HVAC refrigerant leaks are one of the more frequent service calls we handle. The combination of aging systems, high run time, and vibration from constant cycling creates conditions where leak points develop over time, particularly in copper line sets, evaporator coils, and Schrader valves. If your AC is blowing warm air, icing over, or running nonstop without cooling, a refrigerant leak could be the reason. Here’s what you need to know.
Adding refrigerant without fixing the leak is not a solution
Signs You Have a Refrigerant Leak
These symptoms often appear gradually as refrigerant slowly escapes the system. Homeowners in Fort Myers frequently notice one or two of these signs before the system stops cooling altogether.
- Warm or barely cool air coming from the vents despite the system running
- Ice forming on the refrigerant lines, the indoor coil, or the outdoor unit
- Hissing or bubbling sound near the outdoor unit or refrigerant lines
- Electric bills climbing even though your usage has not changed
- The system runs constantly without reaching your set temperature
- Indoor humidity feels worse than usual, as refrigerant also helps dehumidify your home
If you are seeing ice on your system, switch it to fan-only mode to let it thaw before calling a technician. Running the system in cooling mode while the coil is frozen puts direct stress on the compressor and can turn a refrigerant leak repair into a full compressor replacement.

What Causes Refrigerant Leaks
Worn or Corroded Coils
The evaporator coil (indoor) and condenser coil (outdoor) are where refrigerant flows through your system. Over time, especially in Florida’s humid and salty coastal air, coils develop pinhole leaks through a process called formicary corrosion. This is one of the most common causes of HVAC refrigerant leaks in Southwest Florida. Once a coil starts leaking it typically worsens, and coil replacement is often the more cost-effective call over repeated refrigerant recharges. Corroded coils also frequently cause your [AC to freeze up] and ice to form on the lines.
Vibration-Caused Joint Failures
Every time your system starts and stops, it vibrates. Over years of operation, that vibration can loosen or crack the brazed connections where copper refrigerant lines join. These micro-leaks are difficult to detect visually but show up clearly during a proper leak search. Left unaddressed, low refrigerant from joint failures is one of the leading reasons [an AC runs constantly without cooling the home].
Physical Damage to Refrigerant Lines
In Fort Myers older neighborhoods, refrigerant lines sometimes run through tight spaces where they can be pinched, kinked, or nicked during other work on the home. We have seen lines damaged by pest control drilling, landscaping, and roofing work. Physical damage like this causes refrigerant to drop quickly, which is why you may notice your ac blowing warm air or [AC not cooling] within days of the incident.
Factory Defects
Less common, but some systems develop leaks at connection points that were not properly sealed from the factory. These typically appear within the first two to five years of installation and may be covered under manufacturer warranty. If your system is relatively new and already showing signs of a refrigerant leak, a warranty claim is worth exploring before paying out of pocket for [AC repair in Fort Myers].

What We Do to Find and Fix Refrigerant Leaks
Step 1: Electronic Leak Detection
We use a calibrated electronic refrigerant leak detector to pinpoint leak locations with precision. This method finds leaks that visual inspection and dye tests miss entirely, including micro-leaks inside coil walls and behind insulated line sets. It is the most reliable first step in any proper ac refrigerant leak repair.
Step 2: Nitrogen Pressure Test
When a system shows signs of multiple leak points, we pressurize the refrigerant circuit with nitrogen to map every failure point before deciding on a repair approach. This step prevents the common mistake of fixing one leak, recharging the system, and discovering a second leak two weeks later.
Step 3: Repair or Replace
Small, accessible leaks at joints and connections can often be brazed and sealed on the same visit. Coils with significant formicary corrosion or multiple pinholes are better replaced than repeatedly patched. We give you a clear recommendation based on the system age, refrigerant type, and overall condition so you can make an informed decision without pressure.
Step 4: Recharge to Manufacturer Spec
Once the leak is confirmed repaired, we recharge the system to the exact refrigerant level specified by the manufacturer. Not a rough estimate. This ensures your system runs at full efficiency and your ac refrigerant leak repair cost reflects work that actually lasts.

FAQS
Suspected Refrigerant Leak? Don’t Wait.
How do I know if my AC has a refrigerant leak?
Is a Freon leak dangerous to my family?
R-22 Freon and R-410A refrigerants are not acutely toxic in small amounts but they do displace oxygen in enclosed spaces. A significant indoor leak near the air handler can cause dizziness, shortness of breath, and irritation. If you smell something sweet or chemical near your indoor unit, turn the system off and call a technician. Do not attempt to locate the leak yourself.
Can I just add more refrigerant instead of fixing the leak?
