How much does it cost to convert R12 to r134?

It will generally cost you about $200 to have a mechanic convert an AC system for you. If you want to replace a vehicle’s AC system, it will cost between $1,500 and $4,000 with an average cost of $2,750. If you decide to have a professional work on your car, you will have several options for where to get the work done.

When retrofitting a system from R12 to R134a what is required to be done?

Sanden Procedure for Conversion from R-12 to R134a Recover all R-12 refrigerant from the vehicle’s A/C system. Evacuate the A/C system for at least thirty (30) minutes to a vacuum of 29 in. Hg, using R-12 equipment, to remove as much R-12 as possible from the residue mineral oil. Remove all R-12 service equipment.

How do you tell if a car has been converted to R134a?

To tell if it has been converted you can look for a sticker on the unit under the hood, which would indicate that it is R134a. And you can also look for R134a adapters, which would be located on the charge parts.

Can I mix R12 and 134a?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.

How do I switch from R12 to R134a?

How to Convert an R12 to the R134a System

1. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional.
2. Open the engine compartment of your vehicle.
3. Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.

What happens if you put 134a in an R12 system?

R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.

When retrofitting an AC system from R12 to R134a what oil should be recommended?

R-134a systems require PAG (polyalkylene glycol) oil of a certain grade. PAG oil is hygroscopic, meaning that it readily absorbs moisture from the air. Never leave the cap loose when storing PAG refrigerant oil. Some manufacturers recommend using less hygroscopic POE (Polyol Ester) oil instead of PAG after a retrofit.

When was R-134a banned?

In 2012, automobile manufacturers began the transition to new, climate-friendly alternative refrigerants. As a result of a July 2015 rulemaking, by model year 2021, the MVAC systems in newly manufactured light-duty vehicles in the United States will no longer use HFC-134a.

What refrigerant is compatible with R-134a?

There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a and R-744. More on these replacements later.

What happens if you put the wrong refrigerant in your car?

You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you’re not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.

How to convert your car’s a / C system from R12 to R134a?

The A/C system in many older vehicles needs to be converted from R12 refrigerant to R134a refrigerant. This video shows you how to convert your vehicle’s A/C system from R12 to R134a using an IDQ Retrofit Kit. 1. Locate the low-side and high-side A/C service ports.

What’s the difference between R-12 and 134A air conditioning?

Until 1995, most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. Now, the industry standard is R-134a, which is an efficient absorber and carrier of heat without the ozone layer-damaging issues of R-12.

How to retrofit R12 to R134a by classic auto air?

R12 Recovery – Recover refrigerant from the A/C system using a dedicated R12 recovery device (to SAE J1990). R12 Parts replacement – Remove the components to be replaced as part of the retrofit to R134a, as recommended by the A/C system or vehicle manufacturers guidelines. Add 30-50ml PAO oil to a/c system. Retrofit warning labels.

How much does it cost to replace R134a Freon?

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.
