Yeah, that 240v line run suggestion puts a gigantic question mark on anything they've suggested at all. I'd recommend a second opinion.
240v for an attic fan? Wtf?
Yea, fire this "handyman". 240 in the US is for high load devices, like AC, electric stove (electric heat is a direct short), electric water heater.
A fan draws a very small amount of current - less than 5 amps at 120v.
I have a small portable blower (this uses a compressor wheel, so draws more current than a fan), and it's rated for 5 amps.
