Many homeowners consider refrigerant leaks to be an AC performance issue. However, what they don’t realize is that a leak can have serious health and environmental consequences.
When refrigerant leaks from your AC system, it gets released into the air as a gas. Prolonged exposure to the chemicals found in refrigerant can cause headaches, dizziness, and nausea. Refrigerant leaks can also contribute to global warming and greenhouse gas emissions.
Quick Takeaways
- Refrigerant leaks can reduce indoor comfort and air quality.
- Large refrigerant leaks may cause symptoms such as dizziness, headaches, and nausea.
- Modern refrigerants are less harmful than older types but still require professional handling.
- Refrigerant leaks can contribute to greenhouse gas emissions.
- Prompt AC repair helps protect both your home and the environment.
What Is Refrigerant and Why Does It Matter?
Refrigerant is a chemical compound that absorbs heat from the air and releases it to the outdoors, making air conditioning possible. When heat passes over your air conditioner’s evaporator coils, the refrigerant inside absorbs the heat and changes from a liquid into a gas. This hot gas then moves to the outdoor condenser coil and is released into the air. After this process, the refrigerant cools and returns to its liquid form.
Refrigerant circulates in a closed, sealed loop in your air conditioner, which means replacing it isn’t necessary under normal conditions. If your refrigerant levels are low, it usually indicates you have a leak.
Health Effects of Refrigerant Leaks
1. Headaches and Dizziness
Many refrigerants contain fluorinated hydrocarbons. When refrigerant gas escapes into your home, the fluorinated hydrocarbons displace the oxygen. Once oxygen levels drop, your brain starts receiving less oxygen than it needs, resulting in headaches and dizziness.
2. Eye, Nose, and Throat Irritation
If refrigerant leaks into a poorly ventilated space, the gas can irritate your eyes, nose, and throat. Common systems include watery and itchy eyes, nasal burning, and a burning sensation in the throat.
3. Nausea and Short-Term Discomfort
As refrigerant begins to displace the oxygen in the air, you may feel nauseous. This short-term discomfort can be easily remedied if you ventilate the space.
4. Increased Risks in Poorly Ventilated Areas
When refrigerant leaks into the air, it pushes oxygen out. Without proper ventilation and airflow, the buildup of fluorinated hydrocarbons in the air can lead to severe health symptoms.
5. Why Children, Seniors, and Pets May Be More Vulnerable
Because refrigerants are heavier than air, they tend to settle near the floor. As a result, pets, children, and infants face a higher risk of breathing in this gas.
Children and pets also tend to breathe at a faster rate, which can increase the amount of gas they inhale. Seniors and those with respiratory problems may have reduced lung capacity, making it difficult for their bodies to recover from exposure to refrigerant gases.
Can a Refrigerant Leak Make You Sick?
Yes, a refrigerant leak can make you sick. However, most residential leaks are not medical emergencies. But you should never ignore a leak as it can cause mild symptoms of dizziness, headaches, and nausea, especially if you’re in a poorly ventilated space.
Exposure may become more serious if you have a prolonged leak in an enclosed, poorly ventilated space. In addition, if liquid refrigerant comes in contact with your skin, it can cause chemical burns.
Environmental Effects of Refrigerant Leaks
6. Greenhouse Gas Emissions
Every gas has a greenhouse gas footprint, which is measured by its Global Warming Potential (GWP) – how much heat a greenhouse gas traps in the atmosphere. While carbon dioxide has a GWP of 1, refrigerants for residential use have a GWP of about 2,000.
7. Impact on Climate Change
Refrigerant gases trap heat in the atmosphere, directly contributing to global warming. Commercial businesses, such as grocery stores, can leak tons of pounds of refrigerant every year.
8. Why Refrigerants Are Regulated
Refrigerants are regulated by the U.S. Environmental Protection Agency because their leaks can severely impact the environment. Depending on the type of refrigerant, a refrigerant leak can contribute to ozone depletion and global warming.
9. The Transition to Lower-Impact Refrigerants
To limit the environmental impact of refrigerants, companies are now switching to lower-impact refrigerants like A2L, HFOs (Hydrofluoroolefins), and natural refrigerants.
Signs Your AC May Have a Refrigerant Leak
Not sure what to look for? Here are some signs you may have a refrigerant leak.
- Warm air coming from vents
- Ice on the refrigerant lines
- Frozen evaporator coil
- Hissing or bubbling sounds
- Longer cooling cycles
- Higher energy bills
What Should You Do If You Suspect a Refrigerant Leak?
If you suspect you have a refrigerant leak, avoid any DIY repairs. Here are some immediate steps you should take.
- Turn off the system if significant symptoms are present.
- Schedule professional leak detection services.
- Have our technicians repair the leak before recharging your refrigerant.
How Preventive Maintenance Helps Prevent Refrigerant Leaks
Having a refrigerant leak isn’t a pleasant experience. However, our preventive maintenance service can help prevent a leak from happening in the first place.
An annual routine inspection is an important preventive measure. Our technicians at One Hour Air Conditioning & Heating can catch minor issues before they balloon into something more expensive. We can also check the system to see if there are signs of an early leak. Repairing a small leak can help you avoid more damage and expensive repairs later on.
Our preventive maintenance service can also protect your system’s efficiency. We can replace worn-out components, lubricate moving parts, tighten loose connections, and ensure the system is running well. A routine maintenance service can extend the lifespan of your equipment, too.
FAQ
Are refrigerant leaks dangerous to humans?
Yes, refrigerant leaks can be dangerous to humans, especially if you’re in an enclosed, poorly ventilated space. Refrigerant gas displaces the oxygen in the air and can cause dizziness, headaches, and nausea.
Can refrigerant leaks affect indoor air quality?
Yes, especially if you’re in a poorly ventilated space. Refrigerant releases chemicals into the air, displacing oxygen. Inhaling these chemicals can cause health issues, such as burning sensations in the throat, dizziness, and headaches.
What does refrigerant exposure feel like?
If liquid refrigerant comes into contact with your skin, you may suffer from chemical burns. If you inhale refrigerant gas, it can cause nasal burning, nausea, headaches, and dizziness. And if refrigerant gets into your eyes, you may experience a burning or itching sensation.
Are modern refrigerants environmentally friendly?
Modern refrigerants, including hydrofluoroolefins (HFOs), are a lot more environmentally friendly than older refrigerants. HFOs have a near-zero Global Warming Potential (GWP), for example, and break down much faster in the atmosphere.
How can I tell if my AC has a refrigerant leak?
Check for signs such as warm air coming from your vents, a frozen evaporator coil, and hissing or bubbling sounds. You may also smell a sweet, chemical smell.
Should I leave my home if I suspect a refrigerant leak?
If the sweet, chemical odor is strong or you hear a hissing or bubbling sound, then you should leave your home. However, a small leak in a well-ventilated space may not require an immediate evacuation.
