Some of the clearest telltale signs of a refrigerant leak can be observed on your outdoor air conditioning unit. If you can see frosty ice crystals forming on the evaporator coil during hot weather, it’s time to call for service. Bubbling or hissing sound.

Q. How do you tell if you have R12 or 134A?
If it is R12 the caps on the charge fittings will be about the size of the valve stem cap on your tires. If it was R134 then the fitting cap would be between the size of a dime or a nickel.
Q. How do I know if my refrigerant is contaminated?
To check for air contamination, a shop technician should note the pressure on the refrigerant recovery and storage tanks to see if it exceeds the maximum allowable pressure for a given ambient temperature. If it does, there is air in the tank and the tank needs to be purged before the refrigerant can be used.
Q. How do you get rid of contaminated refrigerant?
The best way to recover contaminated or unfamiliar refrigerants is to dedicate a recover-only unit to impure refrigerants. Some equipment manufacturers also offer recover-only units designed to remove these refrigerants. Some refrigerants might be contaminated with flammable substances such as propane and butane.
Q. How do I know if my AC condenser is contaminated?
If your AC condenser is about to experience failure, you may notice one of the following warning signs:
- Loud and abnormal noises coming from the unit.
- Significantly reduced cooling capability from the unit.
- The unit is leaking a noticeable amount of fluid past the typical amount of condensation.
Q. What happens if air is mixed with refrigerant?
When air enters a refrigeration system, it collects in the top of the condenser and is trapped. Air will cause a reduction in condenser surface area, which will cause a high condensing pressure. Air can enter the refrigeration system through a leak in the low side of the refrigeration system.
Q. Can you mix 134a with R12?
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.
Q. What happens if you use the wrong refrigerant?
When using these types of propane refrigerants it is possible that they could combust when putting them in units where they are not designed. This can cause great bodily harm, property damage, and in a severe case even death.
Q. Can R22 and R410A be mixed?
R-22 and R-410a are both refrigerants, true. They can both be used in air conditioners or heat pumps to cool your home during summer. You should never, ever try to mix them in the same system, or use them in a system not rated specifically for that kind of refrigerant.
Q. What freon can be mixed with R22?
The most commonly mixed refrigerants in the field are the replacements for R-22 — R-427A, R-438A, R-422D, and R-407C — which are often combined with the remaining R-22 in the system, said Maiorana.
Q. What happens if you mix R134a and R12?
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.
