Kyle did an excellent job. He had great feedback on the health of my HVAC system and a low cost improvement to ensure the reliability and longevity of my compressor.

Mitchell is the best service tech we’ve ever had at our home! He educated us on many issues helping us better understand our wonderful HVAC system. His work ethic and friendly demeanor are noticeable. McCullough has always provided outstanding service and today was no exception. We are grateful Mitchell was our system inspector today.
