While I didn't get the life I expected out of my Tranquility 27 (just over 11 years), the system has more than paid for itself. Unfortunately, the air coil has developed a slow leak, and the coil replacement cost is likely more than then cost of a new unit. So now I have two questions, should I just replace it with another Climatemaster Tranquility system (a Tranqulity 30 would basically slide right into the same space), and is there a place that sells these to consumers at a better price that someone can point me to other than Ingram's, or is that the only game in town?

Why not have it fixed....evac and solder hole.

I have geo cool that isn't a comparison to your current unit so can't help you there.

Where there's one, there's likely to be many more in short order (it's a known issue with them).
