I looked in my paperwork and didn't see it mentioned?
How do I know if it uses the newer R22 or whatever it is or the older refrigerant?

usually on the nameplate on the condensing unit it will tell you what kind and how much freon it uses.....most all unit use freon 22 and have for the last 20 years or more...there is some new units that use newer blends that are more enviromentally friendly....

If the unit is older than five years, but younger than 20 years, it most likely is R-22.
Newer unit *may* have 410a Puron(r).
Very old unit *may* have R-12 (unlikely).
The outdoor unit will have a name plate near the service valves. On the plate it will indicate the quantity and type of refrigerant.
Ammonia is only used in industrial applications for very low temperature, glycol is a secondary coolant, not a primary refrigerant, and would not be used in a residential A/C.

if the unit was manufactured in the last year or so then the model number indicates the refrigerant that is in it ...if it is more than a couple of years old then it will be R22 for sure...Old Heil model numbers look like this (i will use a typical 10 seer 2 ton condensing unit model number) HAC024AKC...H is for Heil...AC is for A/C...0 is for 10 seer...24 is for 24000btu's (2ton)...A is for standard coil guard and KC are just for engineering changes...all these units were R22 units...the newer units are like this H2A324GKA...H for Heil...2 for R22 (this number is a 4 if it uses R410a)... A is for A/C...3 is for 13 seer (new minimum eff. required in north america)...24 is for 24000 btu (2 ton)...G is for enhanced coil guard...KA is for engineering changes ...guess that sums it up...oh yeah...to the previous answerer that said look for a "puron" label...Puron is the name that Carrier came up with for R410A and is only used by Carrier to describe their R410A units and although ICP(the company that makes Heil and many other fine brands of equipment) and Carrier are both owned by the same company now (UTC) they are operated as completely seperate business groups and Puron labels are not found on Heil equipment. however you may find a pink label that says R410A on the rating label or a yellow or green label that says R22 but these labels tend to fall off after a short period of time in the elements , it is printed on the rating plate but can be kind of hard to see.

All home units use R-22.

I would think that it is R-22. That is what most use.

it should be frion. i don't think it would be wise to use ammonia or glycol ( industrial applications )
