First things first. 1 Clean the coils( both of them). Second the high side or condenser should be around 125 psi in a 70 degree environment. Low side 5-10 ish. Capillary tube systems do not work with sight glasses it will be over charged. You can charge by name plate either with a accurate weight scale or a charging cylinder. Do you have a vacuum pump and the other neccessary equipment like a micron gauge to tell if you have the moisture out? If the thermostat is set too low it could be freezing over and not cooling, if the condenser is plugged it will not cool either. They must be clean before adjusting refrigerant amounts. We get several each year here at the college and most of the time after routine maint the issues are leaks and dead compressors. To be thourough you need super heat and sucooling measurements to see if it is charged correctly. 12 ish for super heat and 8-10 for sub cooling. Much easier if I have my hands on it. We repair quite a few at the tech college here. Sorry for the long answer, Just adding refrigerant is not always the best answer.Also putting your gauges on may take enough refrigerant out to cause a low charge, be careful. Roger
