thank you for the link, that is the exact manual for my unit(lol). i see the check valves you are refering to, and its also the expansion valves, i know for a fact that the valve in the air handler is fine and workin properly, the one in the condensing unit is another story but i really dont have any reason to distrust it being as its new and i have the same issue as the old one. ive even been as far as to check the voltages to make sure it wasnt low and causing it to run slow but thats kinda how it acts, like its just not pumping enough.
