I recently had my annual A/C checkup done through McCullough's Comfort Club program, and was highly pleased with the work done by Jaiden Mendez. He spent around an hour looking at all aspects of the system, taking photos of the internal parts as well as external. Jaiden made suggestions on increasing the A/C's efficiency with a couple of parts, but he was not pushy. He provided a detailed inspection report as well as a list of the suggested parts and their cost. I appreciate how attentive to detail all the McCullough technicians have been over the years when it comes to our HVAC system, and Jaiden is right up there at the top.
