You should always keep the weeds pulled away from your A/C unit
I hate doing yard work more than anything else! I would rather sweep or vacuum the current house five times over if I could avoid working on my yard.
I could even cook a big meal for my extended family if it means that I could simply stop going out to mow twice a week, or raking leaves every day until the trees are bare. I swear I can rake my entire yard free of leaves five times a week, but it still wouldn’t be enough to clear my lawn. Then there’s the struggle of bagging the big pile of leaves up and then dragging them to the curb. I usually create a big mountain of leaf bags right at the roadside. After the lawn is somewhat cleared of leaves, this gives me the chance to mow if the yard needs it, or to detach the weeds that are growing around my house. They start climbing onto our front porch, and the base of the a/c condenser unit. The condenser of the A/C component has a big fan in it to cool the hot compressor inside, so you can probably imagine what could happen if you allowed your weeds to grow unfettered. They would eventually grow through the gaps at the base of your condenser. This could theoretically tangle the fan while it isn’t running. If you left your condenser all alone for a few weeks like this while not running it, you could turn it on some day to find that the fan is making some odd noises. By keeping the weeds cleaned away from around your condenser unit, you can avoid ever running into a problem such as this one.
