Those cottonwoods are terrible. When I was working I'd add an extra spring PM to the HVACR contracts in areas with those trees.
On our trailer I typically wash the evaporator coil (the outside coil) when washing the roof, 2 X/yr. Just a gentle spray with the garden hose, nothing too vigorous.
The condenser coil (the inside coil) gets a spray of "no rinse" coil cleaner about 2X/yr unless conditions merit more.
