Best Backflow Preventer Testing in Honolulu HI

The entire AC system at our unit this company installed at the Central Ala Moana project was down within a few months after we moved in November 2021. Half way through the 1 year warranty period, May 2022, their repair service came refill the freon and re-taped piping. A few months later Oct 2022 the system stop blowing cold again due to freon leak however the warranty expired in Sept. It seems like they did what was needed just to get pass the expiration period. The slow leak from installation continued and was never addressed completely. They are not willing to provide further service and only told us to refer to system maintenance documentation. If you are making a new home purchase, make sure to check all the contractors involved.
