The Call We Get More Than Almost Any Other
Somewhere in Central Florida right now, a homeowner is standing in front of their AC vents feeling warm, slightly humid air blowing out. The thermostat is set to 72. The unit is running. But nothing is happening.
We get this call constantly at All Star Heating & Cooling. And while there are a handful of things that can cause an AC to blow warm air, one of the most common culprits we find on the job is a refrigerant leak. It is one of those problems that sounds simple but carries real consequences if you leave it too long.
So let us walk through what refrigerant actually does, how you can tell if you have a leak, and why AC refrigerant leak repair in Central Florida is not a DIY situation.
What Refrigerant Does and Why Losing It Is a Big Deal
Refrigerant is the substance that makes your AC system work. It cycles between your indoor air handler and your outdoor condenser unit, absorbing heat from inside your home and releasing it outside. Without the right charge of refrigerant, that heat transfer process breaks down. Your system keeps running, keeps consuming electricity, but stops actually cooling your home.
Here is what most people do not realize: refrigerant does not get “used up” the way fuel does. A properly sealed system should hold its charge for the life of the unit. If your refrigerant level is low, that is almost always because it leaked out somewhere. Topping it off without finding and fixing the leak is like pouring water into a bucket with a hole in the bottom.
According to the U.S. Environmental Protection Agency, certain refrigerants are also regulated substances. There are federal rules around how they can be handled, purchased, and disposed of. That is another reason this is not a weekend project.
Signs You Might Have a Refrigerant Leak
We have pulled up to a lot of service calls over the years thinking it would be one thing and finding another. But when a customer describes the following combination of symptoms, refrigerant leak moves to the top of our list fast.
Warm or barely cool air from the vents. Your system is running, your filters are clean, but the air coming out just does not feel cold anymore. This is the most obvious sign.
Ice forming on the refrigerant lines or the evaporator coil. This one surprises people. A refrigerant leak causes the evaporator coil to get too cold and eventually freeze over. You might see ice on the copper lines running to your air handler, or notice water pooling around the indoor unit as the ice melts.
Higher electricity bills without any change in usage. When your AC has to work harder and longer to try to reach your set temperature, it draws more power. A spike in your power bill during a period of consistent weather can sometimes trace back to a refrigerant problem.
A hissing or bubbling noise near the unit. Not always present, but some leaks produce a faint sound as refrigerant escapes through a crack or damaged fitting.
If two or three of these are happening at once, call us. Seriously. The longer a refrigerant leak goes unaddressed, the more strain it puts on your compressor, and compressor replacement is one of the most expensive repairs in the HVAC world.
How We Diagnose and Fix a Refrigerant Leak
When we arrive for an AC refrigerant leak repair in Central Florida, we do not just top off the charge and call it a day. That approach might get your house cool for a few weeks, but the leak will keep leaking.
Our process starts with finding the source. We use a combination of electronic leak detectors and, in some cases, UV dye to trace exactly where the refrigerant is escaping. Common locations include the evaporator coil, the Schrader valves, the copper refrigerant lines themselves, and the solder joints at various fittings.
Once we find the leak, we repair or replace the affected component. For minor fitting or valve leaks, a proper seal or replacement part takes care of it. For a cracked or pitted evaporator coil, replacement is usually the more reliable long-term fix. After the repair, we pull a vacuum on the system, check for any remaining leaks, and then recharge to the manufacturer-specified refrigerant level.
Only then do we test the system’s performance. We want to see your supply air temperature drop into the right range before we leave the job.
The R-22 vs R-410A Situation
If your home’s AC system is older, there is an additional layer to this conversation. Systems manufactured before 2010 were likely built to run on R-22 refrigerant, which has been phased out under federal environmental regulations. As of 2020, R-22 can no longer be manufactured or imported in the United States. Existing stockpiles are available, but supplies are limited and prices have risen significantly.
The EPA’s phaseout of R-22 means that if you have an older system with a refrigerant leak, the cost calculation changes. Paying to repair a leak and recharge an aging R-22 system sometimes makes less financial sense than investing that money toward a newer system that runs on R-410A or the newer R-454B refrigerants.
We will be straight with you about that math when we are on site. Our goal is not to upsell you on a new system when a repair will do the job. But we are also not going to let you spend money on a fix that does not make sense for your situation.
Central Florida Makes This Worse
I want to be direct about something. Florida heat is genuinely brutal on HVAC equipment. Our cooling season runs from roughly April through October, and during those months your AC might be running 12 to 16 hours a day. That kind of continuous use accelerates wear on every component, including the parts that keep your refrigerant sealed inside the system.
We see more refrigerant-related service calls in Central Florida than technicians working in northern states might see in years. The combination of heat, humidity, and runtime demands means your system needs to be in good shape going into summer. A small leak that is manageable in October can turn into a system failure in July when temperatures push past 95 degrees.

What To Do Right Now
If your home is not cooling the way it should, please do not wait and hope it gets better on its own. Refrigerant leaks do not seal themselves. And the longer your compressor runs while starved of refrigerant, the closer you get to a much larger repair bill.
