I know R410 seems to be getting cheaper as the years roll by..... great alternative all the speels...... but I just got a rude awakening on R134a..... I try to keep some around for a few cars and trucks I seem to get around. I called for a price and whewwwwwwwww it tripled in price this year and they expect it to go up more. Funny R12 is not available now and all of a sudden they have an excuse to nail ya with the alternative. Now I get to thinkin... What is R410 going to do when the R22 isn't made anymore? I know its supposed to have all the R22 around for 30 years but is it? Is the supply going to magically disappear? Is there going to be a (supposed)shortage on R410???? I think you can see where I'm goin here.
