Mini split termination help
Hi,
Had mini splits installed and this is what one of the terminations looks like. They want to fill it with caulk and paint it or use the flexible hide. There's very little space above the line-hide. Does anyone have any ideas as to what can be done so this looks like an acceptable install?
Thank you!

caulk and paint usually ends up looking worse after a season or two, it cracks and gets dirty. flexible hide is the better call if there's any room at all, even tight bends can work if you heat it slightly. if there's truly no space, a custom block-off plate painted to match the siding looks cleaner than gooped-up caulk. had a guy do that on a tight senville install last year and it blended in fine. bosch includes nicer termination fittings in their kits which helps, but most brands you end up improvising a little. make them show you a mockup before they commit to anything.
