A/C was working great and then suddenly stopped.Low pressure side is around 40psi until the clutch kicks in and then drops to around 5psi.Clutch cycles on and off every few seconds.Low pressure line gets cold when I bypass the low pressure sensor but still doesn't cool.No moisture dripping from the condenser either.Any help would be …Aug 12, 2017 · r-410a pressure problem, 285/120 psig. i just installed a new split unit r-410a a/c system. it is running at 285/120 psig. the high side seems way low, should be about 420. the correct orifice is installed. this is a 1.5 ton condenser, 2 ton evaporator, and a 0.051 inch orifice. thanks for any suggestions. The unit was charged in heating mode and 11lbs 1 oz of refrigerant was used.

Reader Q&A - also see RECOMMENDED ARTICLES & FAQs. Low side pressure for 410a. Possible cause: Not clear low side pressure for 410a.

This causes high compression ratios and low volumetric efficiencies, which results in low refrigerant flow rates. In summary, there are seven symptoms or telltale signs of a system that has too much refrigerant. High discharge temp. High subcooling in the condenser. High pressures in the condenser. Higher condenser splits.I go over what affects the pressures on the low side and the high side, the saturation state pressures and temperatures, what too low of a pressure means on the vapor side and what too high of a pressure means on the liquid line. I go over the specific ranges of pressure for 410a and r-22. #HVAC Videos.Start heater again. Does low side pressure drop below 30 psi for R-22 unit or 80 psi on a R-410A unit? Figure C.
