Understanding Freon and Its Role in Your AC System
What is Freon?
Freon is a brand name that's become synonymous with the refrigerants used in many air conditioning systems. These substances, such as the older R22, the widely used R410A, and newer alternatives like R32 and R454B, are the lifeblood of your AC unit.
They circulate through the air conditioning system, absorbing heat from inside your home and releasing it outside. This continuous cycle of cool air keeps your living spaces cool and comfortable, especially during those hot Northwest Florida summers.
Why the Change in Refrigerants
Due to environmental concerns like ozone layer depletion and global warming, both R22 and R410A are being phased out or phased down. R22 was found to harm the ozone layer and has been phased out.
While R410A doesn't damage the ozone layer, it has a high global warming potential (GWP), contributing significantly to climate change. As a result, the American Innovation and Manufacturing (AIM) Act of 2020 mandates a gradual phase-down of high-GWP refrigerants like R410A.
Introducing Next-Generation Refrigerants
The HVAC industry is transitioning to newer, more environmentally friendly refrigerants such as R32, R454B, and R466A. These refrigerants have a lower global warming potential and are designed to work with advanced AC systems, offering improved energy efficiency and performance.
Common Causes of Freon Leaks in Home Air Conditioners

Knowing the causes of Freon leaks can help you prevent them and keep your home cool. Here's what you need to know:
Wear and Tear Over Time
As your AC system ages, components like seals and joints can degrade, creating small gaps where Freon can escape. Regular maintenance catches these issues early, preventing minor problems from becoming major headaches.
Corrosion of Metal Components
Formic acid corrosion can create pinhole leaks in the copper tubes of your unit. High humidity and certain chemicals accelerate this process. Protective coatings and regular inspections help prevent this issue.
Factory Defects or Poor Installation
Even new units can leak if there are manufacturing flaws or if installation wasn't done properly. Ensure your AC is installed by reputable professionals to minimize this risk.
Physical Damage to the Unit
External factors like severe weather, debris, or accidental impacts can damage your AC unit, causing leaks. Protect your outdoor unit and inspect it regularly, especially after storms.
Signs and Symptoms of a Freon Leak
Detecting an AC Freon leak early can save you from discomfort and costly repairs. Here are key ac freon leaks signs to watch for:

If your air conditioner is blowing warm air or struggling to maintain the set temperature, a refrigerant might be the culprit. Low refrigerant levels prevent your AC from absorbing enough heat, making it less effective at cooling your home.
Hissing or Bubbling Noises
If your air conditioner is blowing warm air or struggling to maintain the set temperature, a refrigerant might be the culprit. Low refrigerant levels prevent your AC from absorbing enough heat, making it less effective at cooling your home.
Ice Build-Up on Evaporator Coils
Ice formation on the evaporator coils or refrigerant lines is a telltale sign of low Freon levels. When there's not enough refrigerant, the coils get too cold, causing moisture in the air to freeze upon contact.
Increased Energy Bills
An AC freon leak forces your system to work harder to cool your home, leading to higher energy consumption. A sudden spike in your electricity bills without a change in usage patterns might indicate a refrigerant leak.
Health Symptoms in Occupants
Exposure to Freon can cause health issues like headaches, nausea, dizziness, or respiratory problems. If family members experience unexplained symptoms, especially when indoors, an AC refrigerant leak affecting your indoor air quality could be the reason.
Health Risks Associated with Freon Leaks
Refrigerant leaks can negatively impact your indoor air quality, posing serious health risks to your family. When Freon escapes into your home, it displaces oxygen, leading to poor air quality.
Exposure can cause:
- Dizziness
- Headaches
- Nausea
- Difficulty breathing
- Skin or eye irritation
These effects are more pronounced in children, the elderly, and pets. Recent health advisories highlight that prolonged exposure may even affect the central nervous system.
