I had a salesperson from supreme energy come to my house and sell me on a new ac system for my home. It worked for 1 month and then stopped. It has been 2 years since that happened and I can not get them to repair it as they contracted out to a third party to install it in my ac! SE informed me that it is the contractors I need to contact to fix it, so I asked for their contact information and SE said they did not have it anymore... So I asked for their names and again I was told they did not have it anymore! Long story short, SE is a company I would not let near my town let alone in my house. If they come to your door, ask them to sign bill C 59 and keep the copy for yourself.
