Fyi... Since installation in 2016, AC cooled fine for 2 yrs.... On 3rd (2018) year there was no cooling, so we got gas charged and worked fine for whole summer season (may till August).. then in 2019 May when we started, no cooling again... We called other person and he told U-bends are leaked due to constant pressure of gas when the AC is off for like sept till April.. not sure if u-bend story is correct or not.... But we got it changed and gas charged.... It worked best for 2019, 2020 summers.... Now we are back to square one again in 2021
