Cosmopolitan Mechanical Services Inc

I had a hot water tank installed by this company, though Costco.
The tank stopped working while still within warranty.
Besides the fact it took the technician 5 days to repair, all the while my family was stuck without hot water, I was forced to pay an egregious amount of money for the repair, $500.
No communication prior to the repair was disclosed about the cost.
This repair should have been done under the warranty, but they tricked me and said i had to send the bill to Rheem to claim, which is wrong.
If you have a tank installed by them, DO NOT use their services to repair. Call Rheem first.
