Cleaned the coils this morning using spray cleaner and water spray. Kept water out of interior with deflector (license plate) and towel.
Always worth doing but the coils had no pieces of debris, only some dust that formed a little muddy spot on the coach roof.
System ran normally the remainder of yesterday, last night, and so far all day today. I think that with air temperature nearly 100 and enough humidity to put heat index around 130, system reached its limits.
That said, the aluminum fins on the condenser coil are starting to flake away. Sixteen years and a many beachside campgrounds have given salt air its chance.
So, need to consider a new A/C soon. To me that's within a year.
The Big Two are Coleman Mach and Dometic Brisk II. Probably a Ford/Chevy kind of debate, but is one really better?
If Brisk was actually quieter in operation than our present Mach, I think we'd go Brisk.
Advent? Nope, don't think so.
New Atwood? Don't know enough about it...
