Newbie from Houston

Hey ya'll. Long story short, I purchased my very first Toyota in April, a 2003 Toyota Sequoia. I bought it because my Jeep gave me every problem and some and I was done with the repair cost and thought that a Toyota would do the trip. Well, I haven't even had mine for 2 months and the A/C went out. I bought it at a Chevy dealership and it took them 4 months to process my warranty. Can someone recommend a good Toyota dealership that I can take my Sequoia too to get serviced. Thanks.
