Alexis Hung

Starting in August 2020, until January 17th, he refused to complete the job properly unless I pay for part of his mistakes that need corrections. Alex installed our new HVAC system in Aug 2020, took two months to finish thermostat installation, (installed and uninstalled about 3 times). His installation of outside heat pump is wrong (Incorrect unit). Now wants me to pay part of the cost for a different unit that would work per our initial requirement. Details: I hired Hung HVAC to replace my Heating Cooling unit, he started the job in August 2020, finished the installation in October and I paid him. After 24 hours of running the new AC, home was not cooling to set 70 degrees. So, I called him, I stopped the last payment by calling the bank and asked Alex to fix the problem first. A week later he came with another guy, that guy said the thermostat was set to read the basement temperature. So he uninstalled and re-installed the thermostat. in the course of installation, two other guys came, over two months and kept uninstalling and reinstalling the thermostat, and finally called it complete and left. Problem # 2 Alex was hired to install a system that is supposed work until the outside temperature goes down to negative 10 degrees, however, his fresh new install, stops performing when temperature drops down to 20 degrees, (our home temperature went down to 64 degrees when it was set to 70 degrees). Alex first refused to accept anything was wrong, then when I had experts figure out the problem, that Alex installed the wrong outside unit, Alex admitted the error, agreed to re-install. At this point, I withheld $2500 and paid him the rest contract price. Problem # 3: Now Alex wants me to share the additional cost to correct his mistakes. Our communications, on Jan 17: I texted to him, "Alex, I have prepared myself to live with your installation. I will still give you two more weeks, to correct the knowledgeless work. You have this time to correct the mistaken work, if you remain silent, after two weeks,I close this chapter with a two or three star review for you. ~Simon" His Response, "Hi, I am also ready I am waiting for the 2500.00 that we decided on to split because I couldn't do the 5000.00 alone. Let me know."
