I've converted my R-12 system to R-134a. I've charged the system until the pressures are about where they normally are for R-12. Temperatures are in the low 90's with about 60% relative humidity, cooling is "okay" but not great. My fans are both running in their high setting. The sight glass shows a constant foam of bubbles, I never see any clearing. Should I add more refrigerant until they go away? I've seen warnings about "high head pressure" being bad. I don't want to damage anything, so any words of wisdom would be appreciated. How high is "too high" for the high side pressure?
Becomes had to convert gas to a liquid around 300PSI in my opinion. Having a system under charged just to keep pressures low will also cause poor cooling and compressor failures.
