In the fall months of the year, the leaves blow all over the place and 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 time all the debris and leaves crowded my central HVAC unit.
Because of this, I had to clean everything up, and if you end up with leaves and debris around your central HVAC unit, it could easily cause a breakdown or worse. What you need to do is constantly keep up on this to avoid a high HVAC repair bill or having to replace your entire central heating and cooling unit, but a friend of mine did not do this and ended up having to spend several thousand dollars on a brand new, and costly central heating, and A/C unit. I felt pretty bad 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 air conditioner. I will 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 cooling system 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 all the people should do this also.
