Recharging freezer with Freon
bigrockcandymountain:
In Canada, they don't sell cans of 134a refrigerant. They sell 12a like duracool and redtek. They both work really great, especially in systems designed for R12.
I had a Volkswagen car that used a variable diaplacement pump that needed 134a, not a substitute. When researching how to get around this, I discovered that the keyboard cleaner canned air cans are sometimes 134a. You can get a tool called a side can tap to get it out and in to your manifold set. It just pokes a hole in the side of the can.
It all seemed kinda sketchy to me. I never bought the tool. Anybody have any experience with any of that stuff?

I have had no problem using canned air which is r-152a, in place of r-134a.... which you can no longer buy in washington state over the counter.
almost all cars are variable displacement swashplate 5-7 piston compressors.
i might re-fill the r-1234yf in my chevy spark with r-152a. it works fine, but has low capacity. i should get something like 20% more capacity from switching, without even loading the compressor more.

That's another thing i was wondering was if r-152a would work. Thanks for posting. So do you use a side can tap for that?

yeah. best to put the can in the freezer so you lose less product, those side piercing can taps don't work all that great.

All these refrigeration systems use an expansion valve I think my compressor is still good.
I still have this freezer if we could make it work again it would be awesome.
