The birds and those bees
It can sometimes get to be a real hassle when birds do their duty on your central heating and air conditioning system as if it has a sign on it that says “public rest room for birds”! The other thing that is an annoyance is when bees decide to make a home out of your central heating and air conditioning system unit.
Both the birds and the bees have been major headaches when it comes to my central heat and a/c unit and me! At least once a year during the warmer times I have to call an exterminator to get rid of bees who decided to set up shop either on the side of, or inside my central heating and air conditioning system. That can actually get dangerous having that goin on. But even after having a solution for the bees by wiping em all out, you can’t get rid of the birds and them taking a dump on your central heating and air conditioning system unit! I do have a heart and would never want to kill innocent birds. After all, they’re harmless for the most and just want to live their lives like we do. So I ended up just going out an buying a tarp for my central heating and air conditioning system to keep the HVAC unit clean from them doing their thing. And then I just wash the tarp once a month. It is not an ideal solution, however, it works to keep my central heating and air conditioning system clean at the very least. Creatures of the world sure can be annoying!
