1. If you put the blower outside, it essentially creates a -ve pressure inside the room causing outside air (potentially harmful) to get in. Unless you redirect the blower exhaust back into the room to equalize the pressure.
2. Loss of inside heating and cooling due to -ve pressure. Heating/AC will work harder to compensate.
3. Depending on the blower horse power, a smaller unit can be operating much quieter than a AC compressor unit when it kicks in.
4. Wood dust as carcinogen. My view is all about exposure volume. Need to measure against different things to conclude its risk factor. A typically hobbyist just doesn’t produce enough volume to be vulnerable at all, assuming adequate dust extraction at source and reasonable dust collection. Unless one inhales MDF dust for fun factor. :)
Stay healthy, enjoy woodworking. :)
