That wiring is sloppy, all around. Especially that air loop hanging over what look like AC wires. That's bad form. Wire should be secured so it doesn't move. Movement leads to cracks and failed connections.
If you use zip ties take care to get UV-resistant ones as they'll age better. That and don't over-tighten them and cause failures in the insulation around the wires.
Same thing goes for hoses, anything loose enough to move it loose enough to chafe against something. Use padded hangers meant for hoses, not zip ties.
A few hours spent buttoning things up can save you a ton of money later on sudden repairs due to worn-through hoses and wires.
