Auto/mechanic recommendations?

Hey everyone. I’m having some car issues (cold air not working, a clunky sound under my car) that I’d like to get checked out and a get a quote. What auto places/ mechanics around Houston would you recommend that can do that? I don’t want my car to stay overnight anywhere, or feel pressured to leave my car there. I’d just like an overview of what’s wrong first and see if I can take care of it myself.
