How can I make unsightly old air conditioner look better?

Try painting them the same color as walls to make them blend in. Also maybe google question because I recall seeing an option for hiding them.

Hi Karen,

Here's an idea that might help you. You could build this to any height that you need to hide the air conditioner, just be sure to leave room for air circulation around the air conditioner. Wishing you the best.

Also consider painting the outside of the A/C same or color to blend with house color.

You could put a shadow box type frame around them. The face of the air conditioner “frame” can be covered in a decorative metal like chicken wire to camouflage it

Painting the air conditioner could look aesthetically pleasing, but it could cause other issues if not done carefully. Most paints can damage the AC works, which happened to me once because I wasn't attentive enough. It causes it to be less cold, but I luckily solved this issue thanks to this article https://www.socool.sg/why-is-your-aircon-not-cold/. Anyways, if you're not the most careful painter, there are other things you can do to rejuvenate your old air conditioner. Cleaning it is a great start. You can easily use a wet-dry vacuum to remove leaves, weeds, sticks, and other small things to clean or the dirt surrounding it.
