The Ac Refrigerant You Can No Longer Get


For the past few decades, a lot of the ways the world operates have changed to be better for our environment, and that is especially true in the HVAC industry. There are worldwide efforts to eliminate chemicals that hurt the ozone layer. AC systems use refrigerant, which is a known threat to our ozone layer.

The biggest regulatory change to happen recently was here in the United States at the start of 2020. Hardly any homeowners felt any impact from that change right away. But now, a year later, more people who rely on air conditioners for cooling their home will be dealing with the impact of this change.

Our team at Tommy Cool Air stays on top of any advancements and all regulatory changes affecting the HVAC industry. We want to provide you with the information to understand this new R-22 ban so you know how to make the decisions that are best for your home and budget.


The 2020 change affects a chemical known as R22. It is a refrigerant that has been used since the 1950s in air conditioners for homes and businesses. The chemical is most known as Freon, which was the trademark chosen by DuPont Corporation, its first manufacturer.

Even back in the 50s when that refrigerant first came out, people were aware of the damage that refrigerants could do to the ozone layer. Refrigerants in large quantities can deplete the ozone layer and reduce the protection it gives us from the sun’s harmful UV radiation. But, ironically, that was why it was created. It was replacing more harmful refrigerants like CFC-11 and CFC-12 that were in common use at that time.

Governments across the globe took on the goal to eliminate that refrigerant entirely. Regulatory steps to stop using this AC refrigerant have varied across the world. The U.K. and the European Union have already phased it out completely. While the U.S. is on a similar path, we are a few steps behind.

Here in the United States, selling any new equipment that uses it was banned in 2010. But production of it could continue. Maintenance companies could usethat AC refrigerant on already-installed air conditioning systems that are in good working order and do not leak.

But since January 1st, 2020, no more R22 could be produced. And while existing or recycled amounts can still be used on old air conditioning units, that time is almost up. We simply have no way to know how much more of that refrigerant still remains today.


How old is your AC system? If your air conditioner was installed before 2010, it could be using that AC refrigerant. The older it is, the more likely it is using R22. If your air conditioner was put in prior to 2003, the first year restrictions on that refrigerant went into place, it is almost certainly using it.

Homes that have old AC units are the first ones to be affected by this R-22 ban. Those old units are likely to require significant maintenance work. Repairs could now cost you significantly more if that work requires adding R22, as it becomes nearly impossible to find.


Wondering if you have a system that uses it? It is not hard to find out. Go to your outdoor AC unit (the condenser) and look for a nameplate or sticker. That will list what refrigerant your system uses. You may see it as R22 or listed as HCFC-22. You should also be able to find this information in your AC’s user manual.

If you cannot find the answer, feel free to reach out to us at Tiger Heating & Air in Corpus Christi at 361-371-7541, and we will come out to inspect your system.

The replacement for R22 is R410A, most known as Puron®. It first came on the market in 1991 by the Honeywell organization. There are identical refrigerants to R410A that are available from other manufacturers under different names. This newer refrigerant is much more environmentally friendly than Freon. It does not contribute to the depletion of the ozone layer.


If you discover your air conditioner uses refrigerant R22, you do not have many options. And no matter which option you choose, you are going to have to deal with additional expenses.

You Cannot Substitute Refrigerants. Unlike being able to choose a different oil for your car, AC refrigerants are not interchangeable. You cannot just put in R410A in a system that was designed to use R22.

It is possible to have an AC system modified to work with a different refrigerant but doing this sort of retrofit is likely to eventually cost you more than completely replacing your system. Plus, this modification will probably void the manufacturer’s warranty on your HVAC equipment.

If you have an old air conditioner and it is working just fine, you don’t need to do anything right away. But when you eventually run into needing maintenance or repair needs, you will likely be faced with making a quick decision.

Here are your three basic options:

  1. Keep your old air conditioning system and when it needs repair or any service that requires more refrigerant, opt for using recycled R22 refrigerant. However, whether this option will be available to you for long is uncertain. The cost of existing R22 will continue to rise and the available supply of it will continue to diminish.
  2. Have your R22 system retrofitted to work with R410A by a professional Corpus Christi HVAC technician. However, this will most likely void your warranty. Not only that, the expense for the parts and labor to of this modification and future service work may still end up being as much (or more) than just buying a new air conditioner.
  3. Replace your air conditioning system. This will likely be the most expensive option in the short term. But the good news is that a new AC installation is the only option that will permanently solve your R22 problem.
