Never used a vacuum pump or touched AC installs in my life and had it finished in a day - 90% of which was running back to the store for parts I forgot, and a taller ladder. All in, I think I spent $99 on a pump+gauges, $40 for a rubber pad under it, and maybe $40 in sand/gravel bags to pile under to get it leveled out plus two large concrete paving slabs. And the pump will get re-used when I install the other two units I got because it worked fantastically.
