my Noma Backup Power System 1800, which I purchased June 28 2008, stopped functioning properly and when I initially called too see what service was available and asked what the warranty period and was was told they would need a receipt before they could tell me anything. I tracked the receipt down and called back only to be told that it was past warranty and that there was no non warranty service available.
I found it to be ridiculous that they sell a $500 item under their store brand that they can not provide support for and made me track down a receipt before they could tell me the warranty period.
The only solution they had was to buy a new one or call the manufacturer. Based on this experience, I would not buy another Canadian Tire / Noma product again.
