AC went out at 9 in the morning in the middle of summer, and by 1230 they had someone out to check it out and fix the problem. Sam Marquez was my technician and he went above and beyond to get my AC fixed.

I've been trying to keep an older unit alive and the McCullough team went above and beyond. Michael came out, first thing in the morning, found and fixed the issues within an hour. He explained everything in detail and taught me a few things about my unit. Super pleased!

Second time to use McCullough. I submitted a service request online and they sent Raul out the next day. He checked my a/c unit to diagnose the symptoms based on the state of the equipment, and presented repair options in a clear way. Answered all my questions, was very polite and respectful, cleaned up after himself, and left me feeling like I could continue to trust McCullough.
