I will cross-post on Home Improvement.

I live in the Timbergrove area, my HVAC system has rigid ducting and the wrapped insulation is in various stages of failure. This issue has reached a point it needs to be addressed (condensation dripping and soaking the insulation and causing isolated minor ceiling drywall damage). I have had our resident H-Town recco out and quote, they suggested to replace the ducting with flexible instead of rewrapping the ducting. Other than this insulation issue, I have not had or noticed any issues. In my O&G engineer mind, rigid>flexible.

1) Is there any input on this one way or the other?
2) Is there a secondary recommendation (EnviroMax was first bid, NOT Artic) for another estimate to compare?

Keep the rigid. All contractors will tell you to replace because for the most part, that's all they know. But performance is far superior.

Thats what I figured. Thanks to both of yall.

When insulating it, make sure they use the right type of mastic. Essentially paint for insulation, but seals up stuff.

Google it up and ask when someone is insulating it. This Old House has a few episodes on doing it.
