Is Air Conditioner Gas Harmful?

Fast read

Air conditioner refrigerants, such as R22 (Freon) and R410-A, are chlorofluorocarbons (CFCs) and pose serious health risks. Refrigerant leaks can cause nausea, asphyxiation, skin irritation, and increased heart rate. Prolonged exposure may lead to severe health issues like frostbite, skin cancer, cataracts, and unconsciousness.

Common causes of leaks include mechanical damage to refrigerant lines, faulty Schrader valves, and corrosion from exposure to fluorides and chlorides. Leaks in the air conditioner can harm the compressor, causing energy use to go up by 20%. This can result in higher power bills and the risk of compressor breakdown. Immediate action is crucial to prevent these hazards and protect both health and equipment.

Is air conditioner gas harmful to me?

R22 or freon coolants are used in air conditioning equipment. R410-A is the refrigerant used in the most recent versions. All these coolants are chlorofluorocarbons, which pose a number of harmful health risks to humans. As a result, you must handle them with extreme caution. If your air conditioner is not chilling your room as well as it used to or if your evaporator coils are suddenly covered in ice, it’s most probable that harmful gas is leaking from your air conditioner.

The problem of air conditioning gas leaking might permanently harm your machine’s compressor. Furthermore, it will almost probably result in a large rise in your overall power usage.

The most serious issue with gas leakage, however, is that the gas discharged is extremely hazardous to health. Coolant seeping from an air conditioner quickly turns into a gas.

This gas is poisonous and can cause nausea, as well as asphyxiation in some scenarios. Skin irritation and dryness, as well as an elevated heart rate, are all possible side effects of a gas leak. Exposure to this gas for an extended period might result in life-threatening medical issues.

Furthermore, this gas can mix with subterranean water supplies, posing a threat to the untold number of people who rely on these resources. If you have a gas leak in your air conditioning, it’s important to act fast. This applies to both homes and businesses.

What Causes Leakage of Air Conditioning Gas?

Mechanical damage to refrigerant lines

Air conditioners cool by moving refrigerant between the outside condenser coil and the inside evaporator coil to create a cooling effect.

The refrigerant lines, constructed of copper, perform the crucial role of transferring refrigerant between the condenser and evaporator. Mechanical damage to these refrigerant lines might cause an air conditioner to leak. Refrigeration lines that flow through a house’s exterior wall are particularly vulnerable to mechanical damage.

A faulty Schrader valve

A faulty Schrader valve is another common reason. The seal around the valve can sometimes be compromised, resulting in refrigerant gas leaks.

Old air conditioner with corrosion


Corrosion protection for households and industrial gas appliances is tough, but not unattainable. The most prevalent type of corrosion that damages air conditioning systems and causes leaks is pitting corrosion.

Long-term exposure to fluorides in water and chloride in cleaning products can lead to pitting corrosion. Since the chloride and fluoride ions assault the coil, it leaks refrigerant.

Another type of corrosion that causes a leakage is formicary corrosion. Continued exposure to acetic or formic acids, which can be found in cleaning chemicals, paints, plywood, and other materials, causes this sort of corrosion.

What are some of the dangers that gas leaks in an air conditioning unit pose?

The gas seeping from an air conditioner is not only hazardous to your machine’s health, but it also has a severe impact on your health as well, here is how:

They can cause harm to your air conditioner

Air conditioner leaks are a common cause of high power bills. According to various research, a leaky air conditioner uses about 20% more energy. Also, using an air conditioner with a leak can cause the compressor to fail because of excessive strain.

Fixing a leaking air conditioner is cheaper than replacing a compressor. It’s best to fix the problem quickly to save money.

Harmful to people’s health

Human health can be compromised by a gas-leaking air conditioner. Leaky AC units are known to induce headaches and nausea. As CFCs quickly absorb heat, prolonged contact with a pressurised CFC can result in frostbite.

Brief exposure to the gas can make your heart beat faster, make you clumsy, crack your skin, and give you convulsions. Short exposure to the gas can cause increased heart rate, clumsiness, skin cracking, and convulsions. Prolonged exposure can lead to serious health issues such as skin cancer, cataracts, difficulty breathing, fainting, and other problems. In the past, the problem of these leaks has resulted in cases of asphyxiation.
