Cigar,

Yes, in the mild summer climates that you have in Canada, I can see how the marginal lack of efficiency from the conversion will allow your system to cool okay. If you would like to test it, bring it on down to Texas and try it on a 108 degree, 80% humidity day.

Even when they cool well, they are typically short lived as Steve says.

pmckechnie,

I'm sure that Steve had the best interest of his customers in mind when he did all those conversions. It is only AFTER he did them and saw the results, plus seeing the cost of R12 decline that he has come to this conclusion.

Also remember, he and his customers are in one of the hottest climates in the US.

I still am flabbergasted at the reasons for many conversions. For Cigar in Canada, he has no choice if he wants to obey the local law. That's a strong reason. For those who don't have such government invasion into their lives, it costs an extra $30 or $40 to use R12 instead of 134. In order to save that much on refrigerant, people often spend a few hundred or more on other things to make the conversion have a better chance of success. I just can't understand that math. Call me dumb.

I have bought lots of things from ebay and have yet to be burned. There is a system there where you can see the feedback from others who have purchased from that particular seller before. If you pay attention to that feedback you can avoid the ripoff artists.

Best of luck to you both,
