This is a Jandy pool heat pump. model EE-2500T
410a refrigerant. The HVAC guy after welding the leak holes did a vacuum test to ensure no leaks then filled to the required 6 lb pressure.
Thanks. He did the vacuum test and watched the gauge for about 5 mins to see if it moved. When he was satisfied he filled it. He also weighed his tank to show he injected 6lbs. At $50 a lb it was pretty pricy.
I have the guy coming back on Monday and will do just that. The closest bigger cities are: Springfield (1.5 hrs) Tulsa (2hrs), Little Rock (3 hrs), Kansas City (4 hrs) Unfortunately there is no one in this town (zip 72712, Northwest Arkansas), that specializes in heat pumps. The pool companies technicians will not touch these units much less refrigerants, etc. and the HVAC guys only know to do what they do with home HVAC units.
Thanks, XXXXX XXXXX removed a few ounces of ref. yesterday morning and it apparently worked. The unit is running uninterrupted even now, for now. The man is from a larger, but small company. He does have many years of large commercial experience.
So what is the best way to measure refrigerant going in? He did use a scale. And how should he have done a proper evacuation? ( I understand about the soap bubble test).
I found a local large pool company that services Jandy heat pumps. However they can't handle the refrigerant side of it. No way to win here! what's a person to do in my situation where I'll always need two experts?
