Just got a new attic fan from a guy who replaced my duct work, the old fan
was burned out and
he replaced it. Anyway 1 month later its making noises like the bearings
are going. He came over and sprayed WD40 on it and quieted down for
acouple of hours and now its make to making noise.

Is there something else I can use to quiet it down or should I put some
pressure on this guy to replace it. He's just saying "I'm just the
installer, I'm not paying for the fan" then he says who's going to pay me
for the labor?

If it is new, it should be covered by some sort of warranty. Labor may not
be though. WD-40 is a rather poor lubricant and is temporary. You need a
real oil, something like 3 in 1 that will last in a motor. Sounds like a
defective bearing.
