The AC is short cycling. So I bought a can of 134a and added it. The short cycling stopped, but there still wasn't any cold air blowing. As an RV is sits for long periods and the last time they used it the AC worked fine. So there is a leak.
By adding 134a and the AC still not cooling, why didn't that work?
(I have the VIN but don't know how to convert that into engine size for example.) Thanks, Ken
Pressures and temps would do wonders if you want help.
Unbelievable the number of people feel their AC systems are low on "free-on", and this goes back clear to 1956 when AC in consumer vehicles first started becoming popular. Another myth, the the more "free-on", the better. Tantamount to electrical, when you can't see whats going on, need the proper equipment to measure it.
Then augmented with this same assumption to add snake oil to the system to address a problem that could well possibly not even exist. And may do more damage than good. Would think after over a half of a century, this would change. Refrigerant is a technology that is now well over a century old.
It is advisable to ask these questions first before taking any action.
