Jiffy Lube Freon

Retrofitting air-conditioning systems has been losing its popularity due to the decrease in automotive R-12 systems on the road, but I still see motorists asking questions about the proper way of converting their old systems to r-134a.

I have looked at many converted automobiles with very poor performance after the work is done. Some converted AC systems don’t work well or the cold doesn’t last long, because the procedure wasn’t followed properly. Below is a detailed list that covers the steps that should be followed when converting to newer type Freon.

Original equipment manufacturers (OEMs) recommend using polyolester (POE) oil in a unit’s compressor when replacing R-502 with Freon™ 404A. After the oil change, Freon 404A will offer the same operating range as R-502. Regulations on the long-term use of refrigerants vary by region and application, and may change over time.

Tire rotation helps protect tires against uneven wear by moving the tire location on the vehicle. Most tires will exhibit some form of wear based on numerous factors including: wheel alignment, miles driven, driving style and habits, and tire location on the vehicle.

Checking off each step or asking your mechanic to do so can help keep the car interior cool, but also improve the reliability of the AC. Always ask your shop to make sure current EPA legislative mandates are documented and followed.

This freon conversion is a government regulated change to the automobile. Some of these steps require equipment that most people don’t own, but even if you take your vehicle into the auto repair shop it’s nice to know this stuff.

Learning what is required to complete the retrofit properly helps assure the long term reliability of the expensive individual system components. If you do plan to perform these repairs yourself, do yourself a favor and buy an AC conversion kit.

There’s one pictured to the right. Also before you get started please review my auto air conditioning safety tips. Plus check out a few more inexpensive air conditioning tools that I made available below.


How to Retrofit Air Conditioning Systems

  • I always start with a good visual inspection of the entire automobile air-conditioning system. I look for any obvious problems like chafed lines or wet oily spots that may indicate a refrigerant leak.
  • Then I run a good performance test on systems that are still working. I record the temperature at of the ducts and also the pressure readings on the gauges. This is before I perform any repairs to the AC system. You need to know the output temperature before and after.
  • Next I will remove all of the old R12 from the system with an approved recycling machine. In our shop, we have a special machine just for r12 systems.
  • This next step is necessary and a lot of people will skip it. Your A/C compressor will require an oil change. R12 and R134-A use different refrigerant oils. It is necessary to remove the air-conditioning compressor and drain out all the oil.
  • I always measure the amount of refrigerant oil that comes out and install the same amount using approved r134a pag refrigerant oil.
  • If the vehicle is equipped with an expansion valve I remove and clean it. If the system has an orifice tube, I will usually replace it. This is because the orifice has a screen on it that can become partially clogged. Also, this part is usually only a few dollars.
  • Then you remove the receiver dryer or what is also called the accumulator. Again you drain the refrigerant oil out of this part and measure the amount that comes out.
  • Next you will install that amount of 134a system oil in the new accumulator. Note that replacing the accumulator is highly recommended at this point. Especially if the system had no Freon in it before the conversion process.
  • The next step in retrofitting air-conditioning is to permanently install the components that you removed with new O-rings. A good tip is to coat the new O-rings with 134 a refrigerant oil you have been installing in the system. This will increase the lifespan of these O-rings and prevent any small leaks from appearing.
  • Now most of the work is behind you and the fun part begins. It’s recommended that you permanently install the conversion fittings, using a thread locker such as Loctite.
  • Note that these fittings are supplied in a conversion kit that can be had at any parts store. The kit comes with a conversion label you must apply to the vehicle.
  • Next you’ll want to pull a vacuum on the system for at least 30 minutes. This will remove any moisture and impurities that entered the system while it was disassembled.
  • This is also a step that is often skipped when people are in a hurry. Doing this truly adds longevity and reliability to the air-conditioning system.
  • This next step is important because it is time to recharge the system. The rule of thumb is that the replacement R134A Freon is about 80% of the R-12 charge. If you charge the same amount as originally installed the system will not function properly.
  • Next you’ll want to run an AC performance test on your new retrofitted air conditioning system. The temperature may be a degree or two warmer than it was previously and this is a normal condition.
  • Also note that your pressures may also be slightly higher on both the high and low sides. The target low side pressure is about 35 psi. But this will vary with the outside temperature.

Converting Car Air Conditioning

The above procedure is my opinion on the proper way for retrofitting air-conditioning systems. I have seen do it yourself car mechanics as well as professional ones skip several steps that are listed above.

The AC system might operate just fine when finished. The question is how long will it last before a problem develops. Performing all of the outlined steps above will often result in a more reliable automobile air conditioner system for years to come.

If your auto mechanic is performing these repairs, print out this page and ask him to follow all of the steps outlined. Or quiz him on the retrofitting air-conditioning procedure and ask for the old parts.

Things To Be Aware Of When Considering R 22 Replacement Refrigerants


The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants.

Does Jiffy Lube Check Freon

If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22. For one, R 22 is its own refrigerant whereas the replacement refrigerants are made up of several different kinds of refrigerants designed to mimic operating pressures/temperatures of R 22. Equipment manufacturers will also tell you that unless the oil being used in your HVAC system is POE oil you cannot use an R22 replacement refrigerant in the system in most cases (M099 is the exception). Most of the older systems use mineral oil that is less viscous than POE oil, and the mineral oil does not work well with the new R22 replacement refrigerants. If the compressor has been replaced recently or the system is relatively new it may have POE oil in it in which case adding an R22 replacement refrigerant to a system that has little to no refrigerant in it is a viable solution that should be discussed with the homeowner.

  • If the system is still under warranty no manufacturer’s will warranty the system if you use a replacement R22 refrigerant, as their systems have often not undergone testing with the various replacement refrigerants
  • You should never under any circumstances add replacement refrigerant to a system that has any R22 refrigerant left in it.

If the system uses POE oil than you can talk with the customer about removing the existing R22 and using a cheaper R22 replacement refrigerant such as R407C.

Despite what you see on the posted on YouTube/internet it is not advisable to try to add POE oil to a system without completely removing all mineral oil as the oil mixture will gum up metering devices.

If your compressor fails and you elect to change out the compressor as opposed to changing out the entire system, it may be wiser to change out the type of refrigerant to the replacement R22 refrigerants such as R407c. Doing so could save you a considerable amount should your system develop a leak in the years ahead. All new compressors use POE oil and are compatible with R407c and most other R22 replacement refrigerants.

Below you can find different R22 replacement refrigerants and the+/- of each. Legacy Air currently only offers R407c as our choice for an R 22 replacement refrigerant and we do carry it on our trucks. We do not normally carry M099 but will acquire some and install for the customer upon their request in conjunction with a leak repair. Cost is $50 per lb + 1.5 hours labor.
