Ducted air conditioning duct. Is it easy to replace?

I'm all for trying to save some money when I can do something myself, now I have a bit more time, as long as it doesn't need a qualified professional for safety/electrical/gas etc reasons. In that case I'd always get a pro. I've been in the attic of a large heritage place we are renovating and the air conditioning duct is coming off the connections it looks a bit old but the air conditioner itself runs ok for now just that a lot of cold air is leaking into the roof rather than getting into the house :cry:

. To get me through the next year or 2 I want to replace the ducting before thinking about a new air conditioner all together. This looks like that I need, https://store.polyaire.com.au/accessories/flexible-duct/ is it just a matter of removing the old lengths and unwrapping/taping this on, or does it need a pro? It looks like currently the old duct is just taped on between the fittings and vents, and that's all I'm looking to replace. Anyone who has done something similar let me know.

If you can find the parts, have the tools and feel confident in your abilities, then you should give it a go. Just carefully remove the old ducting and replace it with new, mostly following the same pathways set by the original installers, except where you think you can route it more efficiently. Tape is fine, because this is precisely what duct (not duck as some say) tape was made for. Just one thing to consider is your safety. There are cables, a lot of dust and possibly some other hazards in the roof cavity of a heritage house. Some could be problematic if not handled correctly, so take a little time to think it through.

If your home does not have an HVAC system and you plan to add one, you will need to have new ductwork installed. The cost for air duct replacement by a professional technician will depend on the work required. ... Ductwork installation could cost $35-$55 per linear foot on average, including materials and labor
