How many pounds of freon go into a home air conditioning unit?

Answer 1

Hi, Your question is a good one but I have to tell you the truth of things in that you have not given me much to go on with the information you've supplied.
The BTU or tonnage rating and type of unit you are using.
Also the type of refrigerant and condenser design.
Does it have a reserve capacity tank???
Is it air cooled or water cooled
what size refrigerant lines and how long are they this list of stuff could go on and on and on: I will not do that to you.
I will assume your talkin about say a typical home central cooling system with a typical design and installation and give you a ball park.
2 to 4 ton R-22 home central air cooling units with part outside and part inside will be roughly 10 to 15 lbs.
A five ton would be a couple lbs more sometimes.
(NOTE) these are ballpark only and their are extremes that sometimes effect this.
It is however good information as to if you are concerned if you fear your A.C. repairman is milkin you for an exorbitant amount that you need some slide scale to reference to for your own consumer protection and decision making. Oh yes!!!!! just in case you got a rascal servicing your system or suspect so anyway. (Refrigerant DOES NOT WEAR OUT & NEED PERIODIC CHANGING in a normal functioning system).
I've worked on system older than I am that have never had a single drop added to them to give you an example. Hope this helps:
