We called McCullough on this January 2026 crazy weather day because our heater stopped working. Our technician was Craig and he was very knowledgeable, polite and with a great sense of humor. He did a great job. From our experience, everyone at McCollough is great and very professional starting with Eric who answered the phone. I really recommend this place.
