Anyone know how to tell the age of HEIL and any other AC manufacturers equipment?
Do you have CarsonDunlap Technical Reference Guide or Prestions Guide? They are very helpful.
I think heil’s serial number is a letter then the next two digits is the age???
Do you have the model number?
I don’t have either of those documents. i guess I need to see about purchasing them.

Just saw them on Kentons site and it was easier.
