For an HVAC system, how do I punch a hole in the sheet metal and install a take off?

Question

I want to tap into my HVAC system to run some heating registers into a new room. What is the best (and cheap- this rules out that Greentree tool) way to punch a hole into the sheet metal of the square metal soffit and then install a take off?

Answer 1

u can mark the size of the take off and use a chisel on a hard angle to make a whole or gash large enough to use metal sheers to cut out the hole u need........also u can get a cheap attachment that will attach to ur drill........

Answer 2

Answer 3

if you don't have a drill use hammer and nail
