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 undoubtedly incredibly important. Most air conditioning units older than 10 years have an AC refrigerant called R22 that’s commonly recognized as Freon*, and is noted 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 predominant 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. That’s not great. 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 believed to be 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 early 2010 the production and import of R22 decreased. However, servicing current, existing equipment is still permitted if there is an available supply of R22. To ensure the public’s compliance with the new law, all sales of R22 must be acquired by a certified technician. R22 production and import will be continually reduced by law until 2020, when all production and import will be eliminated. Only recycled 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 this sounds like a case study on supply and demand, then you are correct. As you might assume, 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 very limited supply. Prices have only gone up due to scarcity.
Remember that in order to buy R22, you must be an EPA-certified technician. So, the typical homeowner isn’t able to purchase a cylinder themselves. Plus, there are some firm regulations now on how refrigerant must be reclaimed and recycled, which adds to the cost. This expense is passed on to the homeowner as companies must cover the increased overhead connected to R22 repairs. There are requirements for importing, labeling, record keeping, reporting, destruction and reclaiming of R22 from existing units.
So, how does this impact you?
The cost of R22 is dramatically increasing because of the declining 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 correct, it is. This is why when our experts come out to review your unit we check to see what refrigerant your unit uses, and lots of cases, we’ll advise an upgrade as a result 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 typically have R22. However, if you installed your air conditioner after January 1, 2010, then your system 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 locate it, you can check 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 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 familiar 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 and an ozone depletion rating of zero, and it performed slightly better on energy-efficiency tests than R22.
You may have read about “drop-in” replacements for R22. We strongly recommend against this route. Normally a homeowner who is anxious about the cost of replacing their system 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 reality 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 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 need different parts to run, which forces the technician to replace the most expensive components of your system to be compatible with the new refrigerant. If this crucial step is missed, your system will quickly stop working, and you’ll be forced to install a new unit anyway.
Your manufacturer will probably not pay for the parts to make this swap 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 choices with your HVAC provider if you’re worried about cost. At Service Experts Heating & Air Conditioning, we offer financing that makes a replacement doable, and we keep track of any manufacturer and utility rebates that would make it easier to manage 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 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 problem may not apply to you, because it’s likely that your system uses the new, approved replacement refrigerant, R410a. However, systems installed after 2010 might 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 review, if your HVAC equipment was produced prior to January 2010, especially if it’s older than a decade, you have some options:
- Buy an upgraded, more environmentally-friendly system that uses R410a.
- Contact 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.
- Remain 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 AC. You aren’t required by 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 purchase.
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 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 even easier. New AC equipment can be more efficient and present you superior comfort, helping to lower your energy costs.
We do have one more option available in select locations. To provide our customers with high-quality equipment and service at competitive rates, we started the Advantage Program, which is a worry-free program that provides HVAC equipment with a full coverage repair and maintenance plan for a low monthly price.
You could also select 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 exceed 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 available.
If you aren’t sure what type of AC refrigerant your air conditioning system uses, let us help. Call 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 grand part of this by replacing an old R22 unit with a newer, ozone friendly unit.
