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 important. Most air conditioning units older than 10 years use an AC refrigerant called R22 that’s commonly known as Freon*, and is noted 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 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 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 considered 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 was reduced. However, servicing current, existing equipment is still acceptable if 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 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 might assume, 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 risen due to scarcity.
Recall that in order to purchase R22, you’ll need to be an EPA-certified technician. So, the average homeowner can’t purchase a cylinder themselves. Plus, there are some stern regulations now on how refrigerant should be reclaimed and recycled, which raises the price. This expense is passed on to the homeowner as companies are forced 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 units.
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, excluding recycled quantities.
If you’re thinking, “Man, this is starting to sound expensive,” you’re spot-on, it is. This is why when our professionals come out to review your unit we look to see what refrigerant your unit uses, and lots of cases, we’ll recommend 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 unit may not have R22. You can see the type of refrigerant your system runs on by checking 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 check 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 made the switch 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 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 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 information about “drop-in” replacements for R22. We strongly recommend against this option. Usually a homeowner who is uneasy about the cost of replacing their unit seeks out an alternative, and this appears to be an easy solution. It typically costs the homeowner more money, and nearly always voids the manufacturer warranty. The fact 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 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 work at different pressure levels and require different parts to run, which means the technician is forced to replace the most expensive components of your system to be compatible with the new refrigerant. If this critical step is missed, your system will quickly stop working, and you’ll need to get a new unit anyway. If you are insistent on exploring drop-ins, then consult with an HVAC specialist to determine your best option.
Your manufacturer will possibly not pay for the parts to make this swap 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 better to discuss pricing offers 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 avoid an emergency on a hot day, many of our customers decide to do a pre-emptive replacement, and replace an old system before it quits working. 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 likely that your system uses the new, approved replacement refrigerant, R410a. However, air conditioners installed after 2010 could potentially use R22, so it’s ideal to check with an HVAC Expert. You can always check for 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, 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 unit to help make it compatible with an approved air conditioner refrigerant. This is not what we recommend.
- Keep 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. Ultimately, your AC will stop working and it will need to be replaced, and only R410a units will be available for sale.
The most straightforward option is to purchase 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 with 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 give you superior comfort, helping to decrease your energy costs.
You could also pick the status quo and continue using recycled R22 air conditioning refrigerant for the foreseeable future. While this sounds like a nice alternative, the expense 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 accessable.
If you aren’t sure what type of AC refrigerant your air conditioning system uses, our team is here. Call 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 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.
