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 certainly incredibly critical. Most air conditioning units older than 10 years utilize 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 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. Not a great thing. 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 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 the start of 2010 the production and import of R22 became prohibited. However, servicing current, existing equipment is still allowed while 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. 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 are starting to think this is a great topic for an economics professor regarding supply and demand, then you are correct. As you likely understand, older air conditioners more often have 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 reduced supply. Prices have only increased due to scarcity.
Remember that in order to purchase R22, you have to be an EPA-certified technician. So, the typical homeowner is unable to purchase a cylinder themselves. Also, there are some stern regulations now on how refrigerant should be reclaimed and recycled, which raises the price. This fee 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 systems.
So, how will this affect 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, with the exception of 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 review your unit we make sure to see what refrigerant your unit uses, and in many cases, we’ll advise an upgrade because 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 probably have R22. However, if you installed your air conditioner after January 1, 2010, then your air conditioner may not have R22. You can find 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 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 made the switch from R22 to R410a, which you may identify 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 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 information about “drop-in” replacements for R22. We strongly against against this choice. Normally 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 truth 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 air conditioner, 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 operate 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 skipped, 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 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 smart 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 monitor for any manufacturer and utility rebates that would make it easier to swallow a surprising replacement. To avoid an emergency on a hot day, lots of our customers decide to do a pre-emptive replacement, and replace an old AC before it quits working. 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 dilemma may not apply to you, because it’s possible that your system uses the new, approved replacement refrigerant, R410a. However, units 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 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, particularly if it’s older than a decade, you have a few options:
- Purchase an upgraded, more environmentally-friendly system that uses R410a.
- Reach out to an expert to replace the parts in your current AC system 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 AC. You aren’t required by law to replace your air conditioner. Eventually, your AC will quit running and it will need to be replaced, and only R410a units will be available to buy.
The best option is to buy a new, upgraded air conditioner, especially if your current air conditioner is already more than 10 years old. Service Experts Heating & Air Conditioning has lots of financing options that help make the purchase affordable, 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 offer 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 foreseeable future. While this sounds like a great 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, let us 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 switch to an approved AC refrigerant may stressful, 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.
