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 important. Most air conditioning units older than 10 years utilize an AC refrigerant called R22 that’s commonly recognized 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. That’s not great. So, the U.S. EPA, in cooperation with other agencies and groups around the world, began 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 commenced. By the beginning 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 bought by a certified technician. Production and import of R22 will be continually reduced by law until 2020, when all production and import will be forbidden. Only recycled 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 you’re thinking that this sounds like a great case study for an economics professor teaching supply and demand, then you are right. As you likely understand, older air conditioners may have more 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 restricted supply. Prices have only risen due to scarcity.
Don’t forget that in order to buy R22, you must be an EPA-certified technician. So, the average homeowner can’t purchase a cylinder themselves. Also, there are some firm regulations now on how refrigerant is reclaimed and recycled, which increases expenses. This fee is passed on to the homeowner as companies have to 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, how will this affect you?
The cost of R22 is dramatically increasing because of the dwindling 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 technicians come out to inspect your unit we make sure to see what refrigerant your unit uses, and in the majority of the cases, we’ll recommend an upgrade due to the increasing cost of taking care of an R22 air conditioner.
How do I know if my unit uses R22?
If you have an air conditioning system that was built before 2010, your AC will probably 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 checking the appliance’s nameplate. This nameplate is usually found on the outdoor condenser of your central air conditioning system. If you can’t locate it, you can check your user’s manual. Alternatively, 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 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. Throughout 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 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 heard of “drop-in” replacements for R22. We strongly against against this option. Typically a homeowner who is uneasy about the cost of replacing their unit seeks out an alternative, and this sounds like an easy solution. It typically costs the homeowner more money, and almost always voids the manufacturer warranty. The fact about “drop-ins” is that there is no “drop-in” solution where you simply swap out the refrigerant. The phrase “drop-in” is suggesting retrofitting a system, 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 work 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 vital step is avoided, your system will quickly stop working, and you’ll need to get a new unit anyway.
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 purchasing 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 provide financing plans that make a replacement achieveable, and we keep track of any manufacturer and utility rebates that would make it easier to swallow an unforeseen replacement. To avoid emergencies on a hot day, lots of our customers elect to do a pre-emptive replacement, and replace an old AC 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 challenge may not apply to you, because it’s possible that your system uses the new, approved replacement refrigerant, R410a. However, systems installed after 2010 might use R22, so it’s best to check with an HVAC Expert. You can always look for 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 recap, if your HVAC equipment was produced prior to January 2010, especially if it’s older than a decade, you have a few options:
- Purchase an upgraded, more environmentally-friendly system that uses R410a.
- Contact 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.
- Stick with using recycled R22 and burn through costs like it’s the ozone layer.
To be clear, the EPA regulates the production and use of this refrigerant, but not your unit. You aren’t required by 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 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 with your budget, and again, we look out for rebates from HVAC manufacturers and local utilities to make it easier on you. New AC equipment will also be more efficient and present you superior comfort, helping to lower your energy costs.
You could also select the status quo and continue using recycled R22 air conditioning refrigerant for the near future. While this sounds like a good alternative, the cost of servicing old R22 A/C systems is starting to exceed 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 confident what type of AC refrigerant your air conditioning system uses, we can help. Contact Service Experts Heating & Air Conditioning today and we can provide an inspection to find out if you are currently using R22 and, if so, what you can do.
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 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 exaggerated 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.
