Actually, it's pretty cool under my house and even cooler with the AC running and a couple of ducts removed. And, this is our hottest time of the year.
Other than crawling around, it's a very easy process. The inner duct is a pretty tight fit which I secured with hvac tape and then a specialized zip tie. I recommend getting the tool for tightening the ties as it cinches it down tight and then has a cutter for the excess. After the inner duct is secure, you wrap the end with the built-in insulation and pull up the outer foil, which I taped and cinched with a second tie. Guaranteed, this won't come undone without wire cutters. Lastly, it's a good idea to hang the ducts with duct strapping as that keeps it off the ground and less susceptible to rodents.
It actually made the system noticeably quieter as well as more efficient.
