What Will Happen to R22 and How it Affects You
If your air conditioner was installed before 2010 and you don’t know what R22 is then you should probably learn. R22 refrigerant is a chemical that keeps the air coming from your air conditioning system cool, so it’s unquestionably incredibly vital. Most air conditioning units older than 10 years have an AC refrigerant called R22 that’s commonly identified as Freon*, and is referred to by the EPA as HCFC-22. In this guide, we’ll use the name R22. This refrigerant was introduced in the 1950s and became the leading AC refrigerant in the residential heating and cooling industry.
The Montreal Protocol
Several decades later the world realized that R22 refrigerant was aiding in the depletion of the Earth’s ozone layer. Not cool. So, the U.S. EPA, in cooperation with other agencies and groups around the world, initiated a phase out of lots of ozone-depleting agents as part of an international agreement known as the Montreal Protocol. The regulation lists many HCFCs and CFCs (different types of refrigerants that deplete the ozone layer), but R22 is recognized as one of the worst offenders.
Timeline and R22 phase out progress in 2018
In 2003, the phase out of R22 production and imports began. By the beginning of 2010 the production and import of R22 became prohibited. However, servicing current, existing equipment is still permitted if there is an available supply of R22. To guarantee the public’s compliance with the new law, all sales of R22 must be bought by a certified technician R22 refrigerant will be available to service existing air conditioners after 2020.

So how does this affect prices?
If this sounds like a case study on supply and demand, then you are right. As you can imagine, older air conditioners may have more leaks and need repairs. Any air conditioners that are older than 2010 are more likely to use R22, which means there’s a lot more demand for it, and a restricted supply. Prices have only increased due to scarcity.
Recall that in order to obtain R22, you’ll need to be an EPA-certified technician. So, the typical homeowner can’t purchase a cylinder themselves. In addition, there are some strict regulations now on how refrigerant should be reclaimed and recycled, which raises the price. This expense is passed on to the homeowner as companies must cover the increased overhead associated with R22 repairs. There are requirements for importing, labeling, record keeping, reporting, destruction and reclaiming of R22 from existing units.
So, what does this mean for you?
The cost of R22 is radically increasing because of the dwindling supply, and new refrigerant will no longer be available for use at all after 2020, excluding recycled quantities.
If you’re thinking, “Wow, this is starting to sound expensive,” you’re spot-on, it is. This is why when our professionals come out to inspect your unit we look to see what refrigerant your unit uses, and in the majority of the cases, we’ll advocate for an upgrade because of the increasing cost of maintaining an R22 air conditioner.
How do I know if my unit uses R22?
If your home has an air conditioning system that was built before 2010, your AC will likely have R22. However, if you installed your air conditioner after January 1, 2010, then your air conditioner may not have R22. You can check the type of refrigerant your system runs on by checking the appliance’s nameplate. This nameplate is normally found on the outdoor condenser of your central air conditioning system. If you can’t find it, you can grab your user’s manual. If that doesn’t work either, you can call your local Service Experts center. If you have a maintenance agreement with us, we also have your information on hand and a tech can let you know quickly if your unit uses R22.
Instead of Freon, use Puron
The industry has made the switch from R22 to R410a, which you may know by the brand name Puron. For the rest of this article, we’ll use the name R410a (although Puron is a recognized brand, there are other companies that make R410a). There are some key benefits to switching from an R22 air conditioning unit to one that uses R410a. It has a higher safety rating tests than R22.

You may have heard of “drop-in” replacements for R22. We strongly advocate against this option. Normally a homeowner who is concerned about the cost of replacing their unit seeks out an alternative, and this appears to be an easy solution. It often costs the homeowner more money, and nearly always voids the manufacturer warranty. The fact about “drop-ins” is that there is no “drop-in” solution where you just swap out the refrigerant. The phrase “drop-in” is referring to retrofitting a unit, which when done right can cost the homeowner as much, or more, money than installing a new unit that uses R410a. In part, this is because different refrigerants function at different pressure levels and need different parts to run, which results in the technician needing to replace the most expensive components of your system to be compatible with the new refrigerant. If this critical step is skipped, your system will quickly stop working, and you’ll end up installing a new unit anyway. If you are dead set on exploring retrofitting, then consult with an HVAC company to determine your best option.
Your manufacturer will possibly not pay for the parts to make this transition because retrofitting your AC system will likely void the warranty. It’s typically just a temporary fix, but purchasing a new upgraded AC system will probably benefit most homeowners in dependability, satisfaction, and long-term comfort.
It’s better to discuss pricing options with your HVAC provider if you’re concerned about cost. At Service Experts Heating & Air Conditioning, we provide financing plans that make a replacement affordable, and we watch for any manufacturer and utility rebates that would make it easier to swallow an unexpected replacement. To avoid emergencies on a hot day, lots of our customers decide to do a pre-emptive replacement, and replace an old system before it breaks down. If you’re thinking the same thing, then you’re in good company!
If your unit was built after 2010, you’re probably safe
If your heating and air conditioning system was built after January 2010, the R22 phase out problem may not apply to you, because it’s probably that your system uses the new, approved replacement refrigerant, R410a. However, systems installed after 2010 could still use R22, so it’s ideal to check with an HVAC Expert. You can always find this and the refrigerant type by reading the nameplate on your condenser (the condenser is the outside unit).

What do I do if my air conditioner uses R22?
To recap, if your HVAC equipment was produced prior to January 2010, particularly if it’s older than a decade, you have a few options:
- Shop for an upgraded, more environmentally-friendly system that uses R410a.
- Call an expert to replace the parts in your current air conditioner to help make it compatible with an approved air conditioner refrigerant. This is not what we recommend.
- Stick with using recycled R22 and burn cash like it’s the ozone layer.
To be clear, the EPA regulates the production and use of this refrigerant, but not your unit. You are not required by the law to replace your air conditioner. Ultimately, your AC will stop working and it will need to be replaced, and only R410a units will be available to buy.
The most straightforward option is to buy a new, upgraded air conditioner, specifically if your current air conditioner is already more than 10 years old. Service Experts Heating & Air Conditioning has lots of financing options that help make the purchase affordable, and again, we look out for rebates from HVAC manufacturers and local utilities to make it even easier. New AC equipment is more efficient and present you superior comfort, helping to reduce your energy costs.
You could also choose the status quo and continue using recycled R22 air conditioning refrigerant for the time being. While this sounds like a nice alternative, the expense of servicing old R22 A/C systems is starting to surpass several hundred dollars (easily a down payment on a new system). You may also see the prices increase as demand continues to rise on a substance that is no longer produced or widely accessible.
If you aren’t sure what type of AC refrigerant your air conditioning system uses, let us help. Call Service Experts Heating, Air Conditioning & Plumbing today and we can provide an inspection to determine if you are currently using R22 and, if so, which option works best for you.
The good news
While making the switch to an approved AC refrigerant may intimidating, it’s helping to save the ozone layer. These regulations will help guard the ozone layer in the Earth’s atmosphere, which helps block radiation from the sun and prevents serious illnesses, such as skin cancer. It’s not implausible to say that you, as a homeowner, are a big part of this by replacing an old R22 unit with a newer, ozone friendly unit.
