In the fall months of the year, the leaves blow all over the place, then, when you have a storm on top of it, you get all kinds of debris along with the leaves.
This past fall we had a few, and each and every single time all the debris and leaves crowded our central heating and A/C unit.
Because of this, I had to clean everything up, and if you end up with leaves and debris around your central heating and A/C unit, it could easily cause a breakdown or worse, so what you need to do is regularly keep up on this to avoid a high Heating and Air Conditioning repair bill or having to replace your entire central heating and cooling unit, a neighbor of mine did not do this and ended up having to spend thousands of dollars on a brand new, and expensive central heating and A/C unit. I felt pretty awful for him. But it gave me a heads up to take note and not let it happen to me! This is why I always clean up all the leaves and debris that crowds around my central heating and A/C. I never forget to do it either. Even if there is not a storm, I will go out there every single weekend and clean up any leaves that are around the central heat and a/c unit. All it takes is an hour or less of my time to save me thousands of dollars in the long run. I highly recommend that anyone and everyone should do this also.
