I changed my furnace and AC with Cosmopolitan Mechanical Services on November 2017, called the call centre a so many time for different issues for the AC problems this summer. But my recent complain is that the AC is making a disturbing noise. but I have not got any response I had even send a message to the sales person Fahim who sold me the AC/Furnace and send a message to him of a video showing him that the Ac is making noise all he said he will call back and never bothered to contact me again.
I have used the AC not less than one season I have so many issues. and I have a video of the AC with noise problem but Home stars does not upload videos.
I noticed on the most reviews here have similar complain with Cosmopolitan Mechanical Services. I would not recommend such a company if they cannot take care of the client requests professionally. As I am still waiting for a response from them.
