That may work but it also may backfire on them. Just because the fans are mechanically interchangeable does not mean that they all move the same amount of air.
Exactly! The evaporator is designed to require a certain amount of air flow (cfm) across the coil. If the cfm is too high or too low, it will affect the efficiency of the unit. The unit may even freeze up. Before changing the fan blade, the manufacturer of the AC unit should be contacted; the manufacturer will know whether or not the blades can be interchanged.

Been reading for years but hardly ever post. I was camping with friends and came across this possible solution to a problem i've been reading about a lot. Roof a/c units that are very noisy. My friend had a 2014 Tiffin Phaeton with 3 Coleman Mach units on the roof. 2 were very noisy while one was not. The 2 noisy units had a 5 or 6 bladed fan on top and the quiet one had a 3 bladed type. What a difference in sound. All the fans were interchangeable. He is getting with Tiffin about replacing the blades. Hope this helps someone
