Josh was on time and got us back on line in no time. I would recommend him for service and maintenance.

Highly recommend. Our technician, Makayla, is/was highly competent. She diagnosed and fully repaired an issue we were having with our coils within 3 days. Do yourself a favor and call McCullough. We spent far too much time trying to fix the issue with another company. I wish we would have called McCullough sooner.

EJ was very professional and extremely knowledgeable and helpful. There was no "up selling", just the facts and recommendations. We'll see you guys again in about 6 months. Thank you.
