So Your Appliances Still Use Freon: Here’s What to Know

If you have an older air conditioner or refrigerator, you have likely heard the term Freon used to describe the coolant that keeps your home chilly. However, what most homeowners call Freon is actually a specific brand of R-22 refrigerant, and it has been on a long road to retirement.

At Dr. Cool, we want to be your partner for navigating these complex industry changes. Whether you are dealing with a classic R-22 system or a slightly newer R-410A refrigerant model, staying informed about the EPA phase-out is the best way to avoid a cooling catastrophe during a Las Vegas heatwave.

If you don’t know what type of refrigerant your system uses, check your label. Look at the data plate on your outdoor unit to identify your refrigerant type. If it says R-22, that means that your system runs on freon.

The move away from R-22 freon began because it is a hydrochlorofluorocarbon (HCFC). These are ozone-depleting substances that damage the ozone layer when they leak into the atmosphere. To combat this, the Environmental Protection Agency (EPA) and international agreements, such as the Montreal Protocol, mandated a phase-out of R-22 production, which was completed in 2020.

Today, the focus has shifted even further. Modern refrigerants like R-410A (often called Puron) are also being phased out gradually because they are hydrofluorocarbons (HFCs). While HFCs do not hurt the ozone layer, they have a high Global Warming Potential (GWP). To fight climate change, the industry is now moving toward new refrigerants with much lower environmental impacts.

If you are looking at new HVAC systems today, you will notice some changes in the refrigerants used. We have moved past the era of R-22 and are now transitioning away from R-410A.

• R-454B Refrigerant: This is becoming a primary choice for many new unit installations. It has a much lower GWP and delivers excellent energy efficiency.
• R-32: Another popular HFC alternative used in many mini-split systems and air conditioning units.
• A2L Classification: You might hear an HVAC contractor mention that these new fluids are slightly flammable (A2L). Don’t worry! New equipment designed for A2L refrigerants includes built-in leak detection and safety controls to manage the mild flammability risk.

If your current AC unit still runs on R-22 system technology, you don't have to replace it immediately, but you should prepare for the following:

Since the production of R-22 is illegal, the only supply left is reclaimed or recycled from older systems. Depending on how much refrigerant your system needs, a single recharge can cost hundreds to over a thousand dollars, and that's before factoring in labor or the leak repair itself.

When a major component, such as the compressor, fails on an R-22 model, the price to retrofit these parts is rarely cost-effective. Most HVAC units designed for Freon are not compatible with newer refrigerants. In these cases, investing in a new AC or a high-efficiency heat pump is usually the smarter financial move.

As an air conditioning system ages, its lifespan naturally nears its end. Older systems using Freon are far less energy-efficient than new HVAC systems, meaning you are likely paying significantly more on your monthly power bills than you need to.

• Prioritize Maintenance: The best way to keep an R-22 unit alive is to prevent leaks. Regular tune-ups help ensure your AC refrigerant stays inside the system where it belongs.
• Don't Wait for a Total Failure: If your system is over 15 years old, start budgeting for a new unit now. The EPA phase-out means that parts and coolant will only get harder to find.
• Ask About Incentives: Ask Dr. Cool or a tax professional about currently available federal tax credits and NV Energy rebates. These programs and eligibility requirements can change, and we stay current on all available savings.
