Did you notice the 2016 Honda Civic’s A/C refrigerant? Honda’s requirement that this system use POE compressor oil rather than PAG is R-1234yf, and this is not a typo (like other OEMs).
Honda claims that POE oil is utilized since it is less flammable and nonconductive than PAG. R-1234yf is used in the 2016 Pilot, Civic, and Fit EV. New models will have R-1234yf with POE oil as they are updated or released. Honda vehicles require a different type of POE oil for this system than hybrid vehicles do. Honda offers three different kinds of POE oil, and the POE needed for R-1234yf is a unique item. Always verify the car labels to ensure you are using the proper oil and refrigerant before beginning any system repairs.
The EPA’s decision in July 2015 that R-134a would be outlawed in new automobiles sold in the United States beginning with the 2021 model year is also responsible for this change in refrigerant.

Honda began use 1234yf when?
In 2013, General Motors started releasing vehicles on the market with this new technology, and full conversion occurred in 2018. Models from Chrysler, Honda, and Subaru came next in 2017. By 2025, it’s expected that 1234YF will be present in every vehicle.
Is R134a compatible with R1234yf systems?
The EPA has responded to certain inquiries on the use of R-134a in HFO-1234yf systems by explaining why you should not.
EPA SNAP Final Rule from 2015
The MVAC systems (or components of such systems) are regarded as emission-related components as defined in 40 CFR 86.1803 for vehicles for which the manufacturer counts air conditioning credits toward their LD GHG compliance. This classification consists of
provisions for emission-related warranty, specifications for proper operation for the designated useful life, and prohibitions on tampering. For instance, under Title II of the CAA, replacing a refrigerant with one that has a higher GWP, such as HFC134a, would be deemed tampering with an emission-related component if the manufacturer is claiming air conditioning credits for an MVAC system that uses a lower-GWP refrigerant on a specific vehicle as part of the LD GHG program.
How is the 2016 Honda Civic’s air conditioning recharged?
- Start your Civic and let it run until the engine reaches its normal operating temperature.
- A/C should be set to the coldest and most powerful setting. Use a thermometer to check the temperature.
- Open each and every door. Close the valve on the recharge kit.
- When the kit’s gauge is empty, close the valve.
- Replace the refrigerant canister and disconnect the kit. After giving it some time to recharge, take it out. You are welcome to use a towel or a pair of gloves if the surface is chilly to the touch.
- By inserting a thermometer in the AC ducts, you may test the new canister.
- Turn off the engine and the AC in the Civic.

When did vehicles require R1234yf?
All newly produced automobiles must utilize the new R1234yf or tetrafluoropropene refrigerant in their air conditioning systems as of 2021. In an effort to decrease the impact of leaking air conditioning systems on the environment, a new class of refrigerants was developed.
What makes r134 and 1234yf different from one another?
Although R-1234yf might be the ideal R-134a substitute, there is one significant drawback to this new technology. Compared to R-134a, R-1234yf is substantially more reactive. Positively, this greater reactivity is what makes R-1234yf so much more environmentally benign. In contrast to R-134a, which is stable for more than a decade, it tends to interact with other gases in the environment and degrade within a few weeks. A highly reactive refrigerant can be problematic since it can be hostile to the lubricants used in the HVAC system. As a result, the oil degrades, resulting in excessive wear and ultimately compressor failure.
What vehicles use 1234yf?
Currently, R-1234yf is used in the production of more than 90% of the automobiles made by ten OEM groups that are sold in the US. BMW, FCA, Ford, GMC, Honda, Hyundai, JLR, Subaru, Tesla, and Volkswagen Group are some of these OEMs.
What is the refrigerant R-1234yf?
A hydrofluoroolefin (HFO) refrigerant is R1234yf. Hydrogen, fluorine, and carbon atoms make up HFO refrigerants, however there is at least one double bond between the carbon atoms. R1234yf’s composition prevents it from harming the ozone layer and reducing its contribution to global warming. To handle, sell, or store this refrigerant, you do not require an ARCTick refrigerant handling licence or a refrigerant trade authorisation.
Do you sell R-1234yf?
The hydrofluoroolefins class of novel refrigerants includes HFO-1234yf. These refrigerants are comparable to HFC refrigerants, with the exception that they have a substantially lower GPP. By forming a double carbon bond within HFO refrigerants, this is accomplished. If the refrigerant leaks or is vented, this double bond can be easily broken down in the environment. The first of these classes of refrigerants, 1234yf, will take the place of R-134a in automotive applications.
Yes. When purchasing containers with fewer than two pounds of refrigerant, no 609 certification or license is required.
Yes, starting of January 1, 2018, in order to purchase 1234yf refrigerant, you will need to be 609 certified with the EPA. The only exceptions are when buying in bulk or when buying containers with less than two pounds of refrigerant inside. This new regulation also applies to R-134a cylinders.
You need a 608 license to use R-22, R-410a, R-404a, MO99, R-422D, and other HVAC refrigerants.
How much does an AC repair for a 2016 Honda Civic cost?
While parts are priced between $269 and $295, labor costs are predicted to range between $197 and $249. Taxes and other fees are not included in this range, nor are your particular model year or geographic area taken into account. There might be more repairs required. The number and age of Honda Civics on the road are the basis for this category.
What is the price of recharging 1234yf?
With the cost of the previous standard R134A refrigerant at $30 per pound, the national average cost of an R134A recharge in 2018 was roughly $200–300. The average price on the market right now for R1234yf refrigerant is $120 per pound, though. The price rises as a result.
How much does adding Freon to a 2016 Honda Civic cost?
A Honda Civic AC recharge typically costs between $186 and $218. Between $123 to $155 is the projected cost of labor, while the cost of parts is $63. Taxes and other fees are not included in this range, nor are your particular model year or geographic area taken into account.
Which refrigerant does a 2017 Civic contain?
Why are you trying to refill your air conditioning system with refrigerant? Is yours unable to cool properly, and your warranty has run out?
The R-134a refrigerant used from 1994 to 2015 was significantly less expensive than the R-1234yf used in the Civic from 2016 to the present. Since R-1234yf is no longer widely accessible, a license is now needed to buy it in cylinders. It is available in cans for roughly $60 apiece, as opposed to R-134a’s $6 per can, if you look hard enough. Systems using R-1234yf have different fittings than systems using R-134a.
What happens when 134a and 1234yf are combined?
The maximum cooling performance of the two refrigerants may be impacted by a number of design flaws. There is no information available on what might occur with a refrigerant swap because vehicle manufacturers have not disclosed any information on the exchange of system refrigerant. This might involve problems with cooling efficiency and toughness.
R-1234yf refrigerant has a different expansion valve setting than R-134a. When switching from R-1234yf to R-134a, a system may have improper refrigerant flow and heat exchanger mal-distribution, which could result in a reduction in cooling performance or durability issues.
When an Internal Heat Exchanger (IHX), which is frequently utilized in R-1234yf MAC systems, is used, the TXV setting also varies. The outcome could be inadequate cooling or the freezing of the evaporator core due to an increased suction line pressure drop, which could alter the setting for a pressure-controlled compressor.
In dual evaporator systems, where the proper balance of front and back expansion devices helps prevent oil buildup in the rear evaporator, this can be very harmful.
For optimum performance and lower load requirements at colder ambient, evaporator control settings are crucial. When changing the refrigerant, different settings can be needed depending on whether pressure control or temperature control is being used to provide maximum cooling performance.
The refrigerant used in the system has an impact on how the compressor controls the refrigerant pressure, whether it has cycling compressors or variable displacement compressors. It’s possible that switching from R-1234yf to R-134a won’t have an impact on systems that employ air temperature monitoring to operate the evaporator.
If charged with 100% R-134a, R-1234yf systems that control freeze prevention by pressure may experience a loss of cooling performance. This is because R-134a needs to be adjusted at a lower pressure of 3.3 psig in order to achieve freeze protection at 32 F. The outlet air temperature could rise by 4 degrees F (2.2 degrees C) as a result.
When R-134a and R-1234yf are mixed, the refrigerant pressure changes and there is a chance that pressure control systems’ evaporators can freeze up, decreasing system airflow.
Why was R134a replaced with R-1234yf?
You might have noticed that the A/C refrigerant has started to change on several new cars. OEMs have been using R134a for a while. However, OEMs must phase out R134a by 2021 in accordance with government regulations. OEMs struggled to find a successor as a result. R1234yf was chosen by many US OEMs to replace R134a, however some OEMs went a different direction. Now let’s examine these novel refrigerants.
Similar to R134a, R1234yf was developed as a more environmentally friendly alternative to R134a. The main distinction between the two is that R1234yf needs careful handling because it is slightly flammable. The diagnosis process for the HVAC system is the same as it is for R134a. To handle R1234yf, however, you will require several recovery machines and other tools. Some recovery equipment can work with both R134a and R1234yf. These devices will have automatic refrigerant detecting technology. Ports for R1234yf systems are a different size to prevent confusion. It is not possible to retrofit to use R1234yf, unlike when R12 was switched to R134a.
Some European OEMs have chosen R744 instead of R1234yr because to the probable flammability of the latter. R744 is not flammable because it is carbon dioxide. The 2017 E-Class from Mercedes-Benz uses R744 in Europe. The following-generation Audi A8 will also include R744, according to Volkswagen Group. Due to the high pressure needed—roughly 1400 PSI—this refrigerant demands extremely specialized A/C equipment. Safety issues are raised by this as well.
To be sure the right kind of refrigerant is being used, make sure to look for car labels and OEM information. Different refrigerants require various handling, storing, lubrication, and A/C equipment precautions. Whatever refrigerant you are compelled to use, make sure you are trained to manage it.
