Your a/c unit should have a tag on it that tells you which freon is in it.
don.t mix refrigerants
I really don’t think so.
You can’t mix refrigerants. Look on the plate to see what kind of charge your unit has.
There should be a tag on the inside of the cabinet, or possibly on the face of the unit, under the filter cover, that will tell you what type of freon/coolant was used in it. I would stay with the same type.
open it up and look at it some will take the R-134 you just need to check it out first I would imagine so since it is what has become widely used
Your home air conditioner is almost certainly designed for R-22 which has a very different boiling curve than R-134.
No, No and No. Most home A/C units use R-22. They have different boiling temps. You cannot mix them.
NO! Most central units I know use R-22.
Most Central Air units used R-22. Many small window units use R-134a. Check the data tag for type and amount of charge. If it is older than about 14 yrs, it may have R-12, which is obsolete. none are interchangeable, and each unit ws designed with the characteristices of the particular refrigerant use in mind.
If central no, if window unit check tag, probably not.Do not mix!!! and do not try to substitute as each unit is designed for a particular type of gas.Are you sure you don’t need a lisense.where you live?
I agree with others here. No, Use R-22.
