saving heat and cooling cost

Decided to insulate new furnace and duct work in garage. amazed at how much old work had air leaks. already notice fan does not run so much on both heating and cooling

Yup, a little $ and work can save $$$$ in the long run. Makes things quieter, too.

Even if you've done that once, need to check it from time to time- as sticky as it is, duct tape eventually dries out and lets loose, so the joints that were once tight are now leaking.

Never could understand the savings if you have the duct work running through an area that you are heating anyway. It either comes out the register or along the line getting to the register.

Your right. There isn't any savings IF all the stuff is within the heated/cooled area.

One of the smartest ideas and acts I've ever seen on this site.
Air leaks transfer all kinds of heat and humidity. Yet air leaks are ignored and people keeping adding more insulation.
Can't heat or cool a place economically. If the air leaks add up to the similar airflow as having a door or window open.

That doesn't look like the standard duct wrap. What type of insulation was used?
Thanks Angle Iron

Duct tape is not meant for duct joints at all. They should never have started calling it that. Foil duct joint tape or a mastic sealer should be used.
