Why does my AC keep leaking Freon?
The most common cause of AC freon leaks is likely erosion of the metal over time due to formic acid or formaldehyde corrosion. Small holes are formed when the acid eats away at the metal and the unit eventually releases freon. Finally, the last major cause of freon leaks are factory defects.
How long does Freon stay in the air after a leak?
If a leak is present, the refrigerant will simply leak out as soon as it is replaced. So, the coolant will last no more than a few weeks to a few months, depending on the severity of the leak. There may also be more than one leak, which could cause the refrigerant to disappear sooner.
How much does it cost to repair a Freon leak?
The average cost to fix a Freon leak is $200 to $1,000. When there are holes or corrosion on the coils where the refrigerant lives, leaks occur. The refrigerant is important for an AC. If the level is too low, the air may not be properly cooled off.

How do I find a Freon leak in my AC unit?
Here are a few ways HVAC professionals might identify leaks in your system.
- Soap bubbles. Soapy water applied to the suspected refrigerant leak will bubble up and give the location away.
- Ultraviolet (UV) dye. Dye is added to the refrigerant, and a special UV light is used to find leaks.
- Electronic leak detectors.
Is it worth fixing a Freon leak?
A refrigerant leak is one of the most common issues we see in residential air conditioners. If you’ve had the AC for less than 10 years, it’s usually worthwhile to have the leaks repaired—you should still have many good years of life left in the system after this.
What should I do if my AC is leaking Freon?
AC leaking Freon on the high side will usually need a physical repair of the problem. High side pressures can reach over 250 psi. In most cases stop leak will not be able to stay in place in the affected areas under these types of pressures.
Why does my air conditioner have a leak?
If you are low on Freon, it is because you have a leak somewhere in your air conditioning system or heat pump. Freon leaks are typically found at the schrader valve, valve cores, evaporator coil, copper lines, “U” connectors, weld joints, electrical connection to the compressor body, or the copper tubing.
When to turn off the AC when there is a leak?
The answer to this question really depends on where the leak is and how severe. The AC stop leak works best on the low pressure side of the automotive A/C system. When the system is turned off on a hot summer day there could still be 100 PSI of pressure in the low side.
Why is Freon bad for your air conditioner?
Freon contains fluorinated hydrocarbons which can cause a variety of health issues. Because the chemical is colorless and odorless, it’s important to be vigilant if you suspect your air conditioning system has a freon leak.
