I’m search of a mechanic to fix my car AC

I have a Chevrolet Trax 2017 that has had the AC out for a couple months. Now that it’s warming up, I’m looking to get it fixed asap. I’m a women and have never really had to deal with a mechanic. Does anyone have any recommendations for a trustworthy mechanic that isn’t too expensive? I stay in the east Houston area near Northshore.

My AC works but it blows warm/ ambient temp air. I’ve tried replenishing the coolant, but that only helps for a few hours. I think there’s a leak somewhere. Sometimes it will work on a random day too. It’s getting too warm to be out in Houston with no AC.
