Time for new AC units? Let's talk options

pic of my install. See busprojects topic.  45XLE   I brought the pictures forward for a ceiling post but further on there are mini-split pictures.  Your next topic needs to be insulation.. Had one member add spray foam on top or roof 5 inches. then rubber type rv roof. I know this install is 5 yrs plus old and many mile/trips coast to coast.   FWIW   Bob

I took a look at your post. Install looks nice. Do you have photos of your outdoor condenser unit(s)? I'd love to see how you ducted and set those up.

i/m thinking silver brazing is usually better around AC...

maybe that's what you mean't

yes I used the incorrect term. I like to use Blockade rods..

Have you seen those flex lines that can be installed on the mini split line sets out of box? With normal screw on and tighten connections?

I was looking only only found ones you have to braze together.

unfortunately I have not. From what I understand the other option is to make a complete horizontal loop with the line set where it connects to the condenser. The loop can dissipate the vibration like a spring but I have never tried it because if you flex a semi rigid line enough times it will eventually fail, maybe in your life time , maybe not.

I agree that the roof units are workhorses and can cool the coach down fast. They are loud of course, but ducting them helps. Really, the biggest attraction to me for mini splits is their power draw. They are so efficient. Variable speed compressors and heat pumps that are efficient too.
