Why bother planting flowers around the air conditioning unit?

I don’t understand why there is such a need for people to beautify the area around the air conditioning units.

The A/C components need to have air surrounding it.

If there is no way for fresh air to get into the A/C unit, it is impossible for it to create enough conditioned air to cool off your home, but last month, I had to service an air conditioning unit. When I first got there, there were so many sunflowers planted all around the A/C unit. The lady said she just wanted to make it look prettier and to hide the nasty-looking A/C unit. I tried to explain to her the process of airflow and how it worked, and ‌that the crucial sunflowers were blocking off the airflow. She rolled her eyes and told myself and others ‌it was far more crucial for her to have flowers there and make it look pretty. I recommended that she put pansies in front, or marigolds. Any style of flower that would be lower to the ground would be much more passable than crucial sunflowers, which completely covered up the A/C unit. She shrugged and told myself and others to each her own, and she would prefer it if I would just service her A/C unit. In order to service the A/C unit, I had to cut down some of her precious flowers. I carefully dug them out of the ground and laid them off to one side. She called my manager and told him ‌I was destroying her flower bed. She demanded to come out and tell myself and others to stop. When my manager got there and saw what she was talking about, she told the lady there was no way I could service her A/C components with a fence of sunflowers blocking it off.
