I contacted customer service for parts information. The lady I spoke to was rude and unpleasant. When I read off the part number of the board I was inquiring about she felt the need to correct how I pronounced "z" and when I told he I was calling from Saskatoon, Saskatchewan she was completely ignorant. Apparently her education system did not teach her basic geography. Funny how this "dumb Canadian" can point out her location and geographical information yet she cant even recognize a well known city (or at least one that is regularly mocked for it's name). I was inquiring about warranty and she stated that they offer 5 years standard and 10 with registration. The particular unit I was calling about has a manufacture date of Apr 2015, she insisted on a proof of install. Well this "dumb Canadian" can do the simple math and figure out that it is a 4 year old unit and in no chronological sense is this unit over 5 years old. It's a wonder why the local distributors dropped them as a brand...but unfortunately I'm working on a building that has about 125 of these units. Very, very disappointed in her ignorance and service.
