I'm sure thumbtack has some sort of complaint system, and investigate if this contractor you hired has a contractors license..tell them to go ahead with the liens (it's usually a way to try to scare you to pay the ridiculous invoice..) you have proof on the agreed price, and proof that the unit isn't working!
