My cost on those parts is a hair over $3k + tax. In your case, I'd probably throw in a $300 lineset as well.
Like a fool, I don't mark up the parts and usually charge about $1000 for labor. Might need to re-think that, especially since my business is completely legal, insured, licensed and legitimate now. Those insurance premiums hurt. I'm starting to figure out why HVAC companies charge what they do.
