I bought the deal for $269 for installation of attic fan. The deal says "Description: Here's the Deal:Solid steel attic fan including installationSolid steel thermostat to allow for temperature control". No where it says it replaces an old attic fan. So after calling and scheduling an appointment, the guy comes in, sees a solar attic fan previously installed. He tried to convince my wife (I wasn't home unfortunately) that the fan is not working (it is a solar fan and it was working 2 weeks before) and refused to install the new attic fan (I needed two, since my attic is big and need more ventilation) claiming "the offer is to replace an existing fan only" which in no way included in the offer advertising. And of course, he offered to install the new fan but for extra money "around $300". I didn't like their dishonesty, because: 1- I know the previous solar fan is working. 2- He wanted to make his job easier by just taking the solar fan out and put the electric one, ignoring what was written in their offer. Wouldn't trust to do any business, and if you get them, make sure every detail is discussed BEFORE he comes to your house.
