NO AC - UNICO - ATTIC - Upon arrival client mentioned that system was not cooling & the humidity is not being removed from home. Turned on system and checked delta T ok receiving good temperature split from supply ductwork. Checked filter and replaced, checked supply airflow good, currently at 46F from Supply ductwork. Client mentioned that when the system turns off all the humidity rises and feels like the home feels as it did before coil replacement. Checked refrigerant pressures ok. Sub-cooling is within range, pressures do not indicate the system is low. Ambient Temp at 82F , Thermostat in home at 71 degrees. Not much heat load in home at all to verify accuracy of pressures. Low side at 96psi, while adding refrigerant noticed low side stable & not increasing, I am under the impression that there is a restriction in the line-set and we need to return to Replace Filter Drier & Wash Condensing Unit to remove dirt from coils as it is 100% restricted. Office will contact client regardin
