Ford Edge AC Recarching Problem

[Palladini]

We own a 2015 for Edge SEL 4WD and I have a Red Tec 12a Bottle and it will not fit on AC recharge port under hood on the AC line.

This device has worked on any car I had, have they changed the fitting on these newer cars.  Does red tec  have the required fitting to allow me to do this refill?

The different size connectors have prevented you from making a huge mistake.  You're trying to put R12 into an R134 system.   The low pressure side connection for R134 will be a 13mm fitting, for R12 it's 7/16".    Toss the R12 (or better, take it to an AC repair shop so it can be saved in a special tank) and get an R134 kit for recharging.
BTW there should be a sticker near the hood latch telling you what refrigerant is in the system.

OK  Gadgetjq

Going to this site https://www.canadiantire.ca/en/search-results.html?x1=brand;q1=Red+Tek could you tell me what I would need to get?

I don't see an R134A recharge kit anyplace on the site you referenced.  Try Amazon where there are many options.
Here are a couple of examples (from the U.S. site, not CA)

Small containers of R134 https://amzn.to/2DbYYy9 

 

Depending how low your system is you might only need a single can or ????

This is the hose and gauge (that you'll be able to reuse for many years) https://amzn.to/2Z3Vian

Another option is one that includes the bottle of refrigerant already attached to a hose and gauge.  I don't know if you can reuse any part of it though.

Red Tec 12a is a propane based R12/R134 substitute that operates at a lower head pressure. They sell it up here to do-it-yourselfers because the proper refrigerants are only sold to and dispensed by licensed AC service people. As you mentioned, taking it to a qualified professional is the correct thing to do.
