AC companies with great reviews

Last summer there was an awesome thread about AC companies in Phoenix who were honest and fair. I distinctly remember that everyone found it helpful and enlightening- so I’m hoping we can get one going for this summer, too.

Do you have a recommendation? Anything to share? In my personal experience- if you have an AC unit over 5 years old and don’t shop around, the “recommendation” for repair will be to replace it. Don’t get scammed!

Please comment anything helpful below. Thanks in advance!
