If your air conditioner was installed before 2010 and you don’t know what R22 is then you should probably read up. 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 use an AC refrigerant called R22 that’s commonly identified as Freon*, and is stated 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 predominant AC refrigerant in the residential heating and cooling industry.
The Montreal Protocol
Fast forward a few decades and 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 start of 2010 the production and import of R22 decreased. However, servicing current, existing equipment is still permitted as long as there is an available supply of R22. To confirm the public’s compliance with the new law, all sales of R22 must be purchased by a certified technician R22 refrigerant will be accessible to service existing air conditioners after 2020.
The graph above shows the EPA’s consumption allowance of R22 by percentage. The limits on R22 consumption were implemented in 2010 and follow a declining trend until 2020.
So how does this affect prices?
If this sounds like a case study on supply and demand, then you are correct. As you might assume, older air conditioners could more frequently experience 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 reduced supply. Prices have only increased due to scarcity.
Recall that in order to obtain R22, you must be an EPA-certified technician. So, the average homeowner can’t purchase a cylinder themselves. Also, there are some strict regulations now on how refrigerant should be reclaimed and recycled, which raises the price. This fee is passed on to the homeowner as companies must cover the increased overhead related to R22 repairs. There are requirements for importing, labeling, record keeping, reporting, destruction and reclaiming of R22 from existing systems.
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, “Holy cow, this is starting to sound expensive,” you’re spot-on, it is. This is why when our experts come out to review your unit we make sure to see what refrigerant your unit uses, and in the majority of the cases, we’ll recommend an upgrade as a result of the increasing cost of taking care of an R22 air conditioner.
How do I know if my unit uses R22?
If you own 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 unit may not have R22. You can see the type of refrigerant your system runs on by looking at the appliance’s nameplate. This nameplate is normally found on the outdoor condenser of your central air conditioning system. If you don’t find it, you can grab your user’s manual. If that doesn’t work either, you can reach out to 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 right away if your unit uses R22.
Instead of Freon, use Puron
The industry has changed 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 familiar 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 offers a higher safety rating tests than R22.
The truth about “drop-ins” is that there is no “drop-in” solution where you simply swap out the refrigerant.
You may have heard of “drop-in” replacements for R22. We strongly recommend against this option. Typically a homeowner who is uneasy about the cost of replacing their unit seeks out an alternative, and this feels like an easy solution. It often costs the homeowner more money, and almost always voids the manufacturer warranty. The truth about “drop-ins” is that there is no “drop-in” solution where you merely swap out the refrigerant. The phrase “drop-in” is suggesting retrofitting a air conditioner, which when done correctly 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 means the technician is forced to replace the most expensive components of your system to fit with the new refrigerant. If this critical step is skipped, your system will quickly stop running, and you’ll end up installing a new unit anyway. If you are insistent on exploring drop-ins, then consult with an HVAC specialist to determine your best replacement refrigerant.
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 usually just a temporary fix, but buying a new upgraded AC system will probably benefit most homeowners in dependability, satisfaction, and long-term comfort.
It’s smart to discuss pricing options with your HVAC provider if you’re worried about cost. At Service Experts Heating & Air Conditioning, we have financing available that makes a replacement achieveable, and we watch for any manufacturer and utility rebates that would make it easier to handle a surprising replacement. To reduce the chances of an emergency on a hot day, lots of our customers decide to do a pre-emptive replacement, and replace an old system before it doesn’t work. If you’re considering that route as well, 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 challenge may not apply to you, because it’s likely that your system uses the new, approved replacement refrigerant, R410a. However, units installed after 2010 could potentially use R22, so it’s ideal to check with an HVAC Expert. You can always find this and the refrigerant type by checking 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 these options:
- Shop for an upgraded, more environmentally-friendly system that uses R410a.
- Call an expert to replace the parts in your current AC system to help make it compatible with an approved air conditioner refrigerant. This is not what we recommend.
- Stick with using recycled R22 and burn money like it’s the ozone layer.
To be clear, the EPA regulates the production and use of this refrigerant, but not your system. You aren’t required by law to replace your air conditioner. Eventually, your AC will not work and it will need to be replaced, and only R410a units will be available for sale.
The best option is to buy a new, upgraded air conditioner, especially if your current air conditioner is already more than 10 years old. Service Experts Heating & Air Conditioning has many financing options that help to meet your budget, and again, we look out for rebates from HVAC manufacturers and local utilities to help you out. New AC equipment will also be more efficient and present you superior comfort, helping to decrease 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 good alternative, the cost 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 grow as demand continues to rise on a substance that is no longer produced or widely accessable.
If you aren’t sure what type of AC refrigerant your air conditioning system uses, our team is here. Reach out to Service Experts Heating & Air Conditioning today and we can provide an inspection to find out if you are currently using R22 and, if so, which option works best for you.
The good news
While making the transition 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.
