A bubble test is the fastest and easiest method for finding Freon leaks but is more effective on larger leaks than smaller ones. The larger the hole, the more easily the solution will reveal a leak.
Steps to Check Refrigerant Levels
Turn off the air conditioner and locate the service valves. Attach the manifold gauge set to the service valves. Turn on the air conditioner and observe the pressure readings, which should be between 30-40 PSI for most systems (though some may require higher or lower pressures).
Freon itself is not particularly poisonous, so a slow leak isn't going to harm anyone. It can suffocate you, but moderate exposure is not very harmful Refrigerant Poisoning: Symptoms, Treatments & Prevention.
If it takes longer and longer for your home to cool off, it could indicate a problem with refrigerant. Your indoor thermostat might be inching up in temperature and humidity for no explainable reason. Another classic symptom is if your air conditioner doesn't cool well during the day, but catches up in the evening.

An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
Mild symptoms of Freon exposure include excitability, dizziness, changes in heart rate, and headaches. The lining of the throat or nose may become irritated, and the throat may swell. Pain in any exposed mucous membranes, such as the mouth, throat, or eyes, is common after exposure.
How well a person does depends on the severity of the poisoning and how quickly medical help was received. Severe lung damage may occur. Survival past 72 hours usually means the person will have a complete recovery. Sniffing Freon is extremely dangerous and can lead to long-term brain damage and sudden death.
Leaking Freon can also damage your appliance and make it less efficient. Inhaling small amounts of Freon is not harmful and will not cause long-term health effects. However, if you are exposed to large amounts of Freon, it can lead to dizziness, headaches, nausea, and difficulty breathing.
Freon leaks can be hazardous. Direct exposure to AC refrigerant can cause health problems such as headaches, dizziness, and respiratory issues. If you suspect a refrigerant leak, it's crucial to ventilate the area and seek professional help from HVAC professionals to prevent further damage and health risks.
Refrigerant, or Freon, poisoning can occur if a person inhales or consumes the chemicals from cooling appliances. Symptoms can include headache, coughing, and nausea. Accidental refrigerant poisoning is rare but can occur when a person works directly with cooling chemicals.
Freon is generally odorless in small quantities, making it difficult to detect leaks based on smell alone. However, when a leak occurs, a faint, sweetish odor may be noticeable. Some people describe this smell as similar to acetone, nail polish remover, or even chloroform.
AC leak repair costs $200 to $1,500 on average to find and fix the leak and refill the Freon. Costs depend on the HVAC location, severity, leak test method, refrigerant prices, and replacement parts. An AC leak test costs $100 to $330 for detection only.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Electronic Leak Detector Test
As the name suggests, the HVAC tech runs this tool along the refrigeration components to detect any R22 or R410a outside of the system. Most HVAC technicians will start a leak test by using this device, as it can be more cost effective in finding a leak.
Theoretically, Freon can last forever. It is not burned up like fuel. When an air conditioning system is in top shape, the refrigerant will be continually recycled within a closed system, to cool your home.
This means that an individual could have no idea that they are in the presence of deadly amounts of freon. Freon poisoning can even be fatal after 72 hours of prolonged exposure to high amounts of the chemical.
One significant health risk is refrigerant poisoning. Inhaling Freon or other refrigerants, even in small amounts, can lead to headaches, dizziness, and nausea. Exposure to refrigerant fumes can quickly escalate to more severe health issues, such as loss of consciousness and even death.
Freon™ is a halogenated hydrocarbon often used as a refrigerant. When inhaled recreationally, it has the desired effects of euphoria and intoxication. Toxic effects include cardiovascular and neurologic insults such as arrhythmias and seizures, and less well-described toxicities include airway and lung injury.
Refrigerant can leak through even when your AC unit is turned off due to the pressure that it's under, so it's important to get it checked out as soon as possible. Refrigerant leaks can be very dangerous and should never be dealt with on your own.
Most cars hold between 28 and 32 ounces of refrigerant (or about 2—3 12oz cans), however larger vehicles and those with rear A/C will likely hold more. Check your vehicle manual for the system capacity for your specific vehicle.
