Our Awards & Certifications

At McCullough, we know our team is special because we hire them that way, and we train them that way. McCullough employs some of the most experienced and well-trained heating & air conditioning technicians in this business. We then provide a structured, rigorous, and exciting ongoing education program that keeps our service and installation personnel on top of every needed

Our technicians aren’t just trained to be good at what they do, but to be great communicators, too. Best of all, we hire people who actually care — something you can’t teach or pay for. Our team will treat you with respect on every phone call and every service call.

Led by McCullough owner Al D’Andrea, our team has cultivated a deep and enthusiastic passion for the work we do. We want to be masters of our craft, not just “good enough” and it shows.


The McCullough team has acquired and maintained all of these certifications among us, and many others. We care about meeting and exceeding national and global standards of excellence in HVAC. We also set our own bar very high.
