The swap itself is easy if the new fan fits the old housing. If you're replacing the whole thing, the pain is getting the old housing out from the attic and the duct connection - that's what takes the afternoon. Breaker off first. Measure the old housing before buying and check the duct size matches (most are 4 inch). Make sure it vents outside, not into the loft. And seal the duct joins with foil tape, not cloth duct tape.
