I placed a service claim on January 2021 for the central heater units not functioning. Despite repeated claims for the same issues and they kept sending different service companies for diagnosis, it is May 2021, they still can't fix or replace the unit. It is for my elder parents' condo, and they had to put up with their small portable heater from Jan~ for a couple of months. It is a horrible company. I strongly recommend not to get a contract with them if you have any choice.
