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 recognized 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
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 launched. By early 2010 the production and import of R22 was reduced. However, servicing current, existing equipment is still allowed 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 bought 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’re thinking that this sounds like a great case study for an economics professor teaching supply and demand, then you are correct. As you likely understand, older air conditioners could more frequently experience leaks and need repairs. Any air conditioners 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.
Remember that in order to purchase R22, you must be an EPA-certified technician. So, the typical homeowner is unable to purchase a cylinder themselves. Also, there are some firm regulations now on how refrigerant is reclaimed and recycled, which raises the price. This expense is passed on to the homeowner as companies are forced 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 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, “Holy cow, this is starting to sound expensive,” you’re correct, it is. This is why when our technicians come out to assess your unit we check to see what refrigerant your unit uses, and in many cases, we’ll recommend an upgrade as a result of 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 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 looking at 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 quickly if your unit uses R22.
Instead of Freon, use Puron
The industry has moved 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 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 read about “drop-in” replacements for R22. We strongly against against this option. Usually a homeowner who is anxious 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 nearly 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 purchasing 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 means the technician is forced to replace the most expensive components of your system to be compatible with the new refrigerant. If this crucial step is avoided, your system will quickly stop operating, 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 company to determine your best option.
Your manufacturer will possibly not pay for the parts to make this switch because retrofitting your AC system will likely void the warranty. It’s typically just a temporary fix, but shopping for a new upgraded AC system will probably benefit most homeowners in dependability, satisfaction, and long-term comfort.
It’s wise to discuss pricing offers 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 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, lots of our customers elect to do a pre-emptive replacement, and replace an old system before it breaks down. If you’re of a similar mind, 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 likely 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 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 review, if your HVAC equipment was produced prior to January 2010, particularly if it’s older than a decade, you have a few options:
- Shop for an upgraded, more environmentally-friendly system that uses R410a.
- Call an expert to replace the parts in your current unit to help make it compatible with an approved air conditioner refrigerant. This is not advised.
- 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 system. The law doesn’t require you 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 buy.
The best option is to get a new, upgraded air conditioner, specifically 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 easier on you. New AC equipment can be more efficient and give 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 time being. While this sounds like a good alternative, the price 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 increase as demand continues to rise on a substance that is no longer produced or widely accessable.
If you aren’t aware of 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 determine if you are currently using R22 and, if so, what you can do.
The good news
While making the switch 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 implausible 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.
