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 certainly incredibly critical. Most air conditioning units older than 10 years use an AC refrigerant called R22 that’s commonly known as Freon*, and is stated 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
Several decades later 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 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 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 launched. By early 2010 the production and import of R22 decreased. However, servicing current, existing equipment is still acceptable as long as 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. The 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 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 correct. As you can imagine, 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 reduced supply. Prices have only gone up due to scarcity.
Recall 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. In addition, 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 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 units.
So, what does this mean for 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, with the exception of 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 assess your unit we make sure to see what refrigerant your unit uses, and in many cases, we’ll advise an upgrade as a result of the increasing cost of sustaining 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 likely 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 normally found on the outdoor condenser of your central air conditioning system. If you can’t locate 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 recognize by the brand name Puron. In the remainder 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 valuable benefits to switching from an R22 air conditioning unit to one that uses R410a. It offers 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 heard of “drop-in” replacements for R22. We strongly against against this option. Normally a homeowner who is uneasy about the cost of replacing their unit seeks out an alternative, and this sounds like an easy solution. It usually costs the homeowner more money, and almost 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 suggesting retrofitting a air conditioner, which when done correctly 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 demand 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 avoided, your system will quickly stop operating, 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 wise 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 affordable, and we keep track of any manufacturer and utility rebates that would make it easier to manage an unexpected 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 doesn’t work. 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 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.
- 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.
- Remain 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 quit running and it will need to be replaced, and only R410a units will be available to purchase.
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 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 reduce 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 choose the status quo and continue using recycled R22 air conditioning refrigerant for the foreseeable future. While this sounds like a good alternative, the price of servicing old R22 A/C systems is starting to go over 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 confident what type of AC refrigerant your air conditioning system uses, we can help. 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 be frustrating, 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 implausible to say that you, as a homeowner, are a large part of this by replacing an old R22 unit with a newer, ozone friendly unit.
