If your air conditioner was installed before 2010 and you don’t know what R22 is then you should probably find out more. R22 refrigerant is a chemical that keeps the air coming from your air conditioning system cool, so it’s unquestionably incredibly critical. Most air conditioning units older than 10 years utilize an AC refrigerant called R22 that’s commonly identified as Freon*, and is noted by the EPA as HCFC-22. In this blog, 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
Moving ahead a few decades the world realized that R22 refrigerant was aiding in the depletion of the Earth’s ozone layer. Not a great thing. So, the U.S. EPA, in cooperation with other agencies and groups around the world, initiated a phase out of many 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 became prohibited. However, servicing current, existing equipment is still acceptable while 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. The production and import of R22 will be continually reduced by law until 2020, when all production and import will be eliminated. Only recycled R22 refrigerant will be obtainable 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 more often have leaks and need repairs. Any units that are older than 2010 are more likely to use R22, which means there’s a lot more demand for it, and a very limited supply. Prices have only gone up due to scarcity.
Remember that in order to obtain R22, you’ll need to be an EPA-certified technician. So, the normal homeowner is unable to purchase a cylinder themselves. Plus, there are some firm regulations now on how refrigerant should be reclaimed and recycled, which raises the price. This cost 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 systems.
So, how does this impact you?
The cost of R22 is considerably increasing because of the diminishing supply, and new refrigerant will no longer be available for use at all after 2020, with the exception of recycled quantities.
If you’re thinking, “Holy cow, this is starting to sound expensive,” you’re right, it is. This is why when our experts come out to inspect your unit we check to see what refrigerant your unit uses, and in the majority of the cases, we’ll recommend an upgrade because of the increasing cost of sustaining 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 typically have R22. However, if you installed your air conditioner after January 1, 2010, then your unit may not have R22. You can find the type of refrigerant your system runs on by checking the appliance’s nameplate. This nameplate is usually found on the outdoor condenser of your central air conditioning system. If you can't find it, you can read your user’s manual. Alternatively, 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 immediately if your unit uses R22.
Instead of Freon, use Puron
The industry has made the switch from R22 to R410a, which you may identify by the brand name Puron. For the rest of 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 provides a higher safety rating and an ozone depletion rating of zero, and it performed slightly better on energy-efficiency 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. Typically a homeowner who is anxious about the cost of replacing their system seeks out an alternative, and this appears to be an easy solution. It typically costs the homeowner more money, and virtually 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 right can cost the homeowner as much, or more, money than purchasing a new unit that uses R410a. In part, this is because different refrigerants operate 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 work with the new refrigerant. If this critical step is missed, your system will quickly stop working, and you’ll be forced to install a new unit anyway.
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 worried about cost. At Service Experts Heating & Air Conditioning, we offer financing that makes a replacement achieveable, and we watch for any manufacturer and utility rebates that would make it easier to handle an unexpected replacement. To reduce the chances of an emergency on a hot day, a lot of 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 problem may not apply to you, because it’s possible that your system uses the new, approved replacement refrigerant, R410a. However, units installed after 2010 could still use R22, so it’s best to check with an HVAC Expert. You can always check for this and the refrigerant type by reviewing the nameplate on your condenser (the condenser is the outside unit).
What do I do if my air conditioner uses R22?
To review, if your HVAC equipment was produced prior to January 2010, especially if it’s older than a decade, you have these options:
- Buy 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 advised.
- Keep 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 system. The law doesn’t require you to replace your air conditioner. At some point, your AC will stop working and it will need to be replaced, and only R410a units will be available to purchase.
The ideal option is to buy a new, upgraded air conditioner, particularly if your current air conditioner is already more than 10 years old. Service Experts Heating & Air Conditioning has many 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 can be more efficient and present you superior comfort, helping to reduce your energy costs.
You could also pick the status quo and continue using recycled R22 air conditioning refrigerant for the near future. 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 obtainable.
If you aren’t sure what type of AC refrigerant your air conditioning system uses, let us help. Contact Service Experts Heating & Air Conditioning today and we can provide an inspection to confirm if you are currently using R22 and, if so, which option works best for you.
The good news
While making the move to an approved AC refrigerant may be frustrating, it’s helping to save the ozone layer. These regulations will help protect 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 big part of this by replacing an old R22 unit with a newer, ozone friendly unit.
