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 certainly incredibly critical. Most air conditioning units older than 10 years use an AC refrigerant called R22 that’s commonly identified as Freon*, and is referred to by the EPA as HCFC-22. In this article, 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, began a phase out of several 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 considered one of the worst offenders.
Timeline and R22 phase out progress in 2018
In 2003, the phase out of R22 production and imports launched. By early 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 guarantee the public’s compliance with the new law, all sales of R22 must be acquired by a certified technician R22 refrigerant will be available 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 you are starting to think this is a great topic for an economics professor regarding supply and demand, then you are right. As you can imagine, older air conditioners could more frequently experience leaks and need repairs. Any systems 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 gone up due to scarcity.
Recall that in order to buy R22, you have to be an EPA-certified technician. So, the normal homeowner can’t purchase a cylinder themselves. Also, there are some stern regulations now on how refrigerant is reclaimed and recycled, which raises the price. This expense is passed on to the homeowner as companies have to cover the increased overhead associated with R22 repairs. There are requirements for importing, labeling, record keeping, reporting, destruction and reclaiming of R22 from existing air conditioners.
So, how does this impact you?
The cost of R22 is radically increasing because of the diminishing supply, and new refrigerant will no longer be available for use at all after 2020, except from recycled quantities.
If you’re thinking, “Wow, this is starting to sound expensive,” you’re correct, it is. This is why when our experts come out to assess your unit we check to see what refrigerant your unit uses, and in many cases, we’ll advise an upgrade due to the increasing cost of sustaining 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 typically have R22. However, if you installed your air conditioner after January 1, 2010, then your system may not have R22. You can find the type of refrigerant your system runs on by reading the appliance’s nameplate. This nameplate is typically found on the outdoor condenser of your central air conditioning system. If you can't find it, you can grab your user’s manual. Otherwise, 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 right away if your unit uses R22.
Instead of Freon, use Puron
The industry has moved from R22 to R410a, which you may identify by the brand name Puron. In the remainder this article, we’ll use the name R410a (although Puron is a well-known brand, there are other companies that make R410a). There are some serious benefits to switching from an R22 air conditioning unit to one that uses R410a. It has 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 read about “drop-in” replacements for R22. We strongly recommend against this route. Usually a homeowner who is concerned about the cost of replacing their unit seeks out an alternative, and this sounds 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 referring to retrofitting a air conditioner, which when done properly can cost the homeowner as much, or more, money than buying a new unit that uses R410a. In part, this is because different refrigerants function at different pressure levels and require different parts to run, which forces the technician to replace the most expensive components of your system to work with the new refrigerant. If this critical step is avoided, your system will quickly stop running, and you’ll be forced to install a new unit anyway. If you are dead set on exploring this option, then consult with an HVAC specialist to determine your best alternative.
Your manufacturer will typically not pay for the parts to make this transition because retrofitting your AC system will likely void the warranty. It’s normally 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 better to discuss pricing options with your HVAC provider if you’re concerned about cost. At Service Experts Heating & Air Conditioning, we have financing available that makes a replacement affordable, and we watch for any manufacturer and utility rebates that would make it easier to manage an unforeseen replacement. To reduce the chances of an emergency on a hot day, lots of our customers elect to do a pre-emptive replacement, and replace an old AC before it quits working. 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 challenge may not apply to you, because it’s probably that your system uses the new, approved replacement refrigerant, R410a. However, air conditioners installed after 2010 could still use R22, so it’s wise to check with an HVAC Expert. You can always look for 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, specifically if it’s older than a decade, you have a few options:
- Purchase an upgraded, more environmentally-friendly system that uses R410a.
- Reach out to an expert to replace the parts in your current unit to help make it compatible with an approved air conditioner refrigerant. This is not what we recommend.
- Remain 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 are not required by the law to replace your air conditioner. Ultimately, 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 purchase a new, upgraded air conditioner, specifically if your current air conditioner is already more than 10 years old. Service Experts Heating & Air Conditioning has several financing options that help with your budget, 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 give you superior comfort, helping to lower 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 price 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 climb as demand continues to rise on a substance that is no longer produced or widely available.
If you aren’t confident what type of AC refrigerant your air conditioning system uses, our team is here. Contact Service Experts Heating & Air Conditioning today and we can provide an inspection to determine if you are currently using R22 and, if so, what’s the best next step.
The good news
While making the switch to an approved AC refrigerant may stressful, it’s helping to save the ozone layer. These regulations will help defend 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 far-fetched to say that you, as a homeowner, are a grand part of this by replacing an old R22 unit with a newer, ozone friendly unit.
