I've had McCullough for several years to maintain my AC and heat unit. They send me a reminder and I pay for the maintenance monthly which makes budgeting easy. Makayla Morgan phoned prior to arrival and showed up on time. My annual maintenance went smoothly and Makayla explained what he what was being done the entire time. Makayla went above and beyond by also testing my gas appliances for leaks. I would highly recommend this locally owned business. Thanks to the McCullough Team for keeping me comfortable.

Jaiden was very helpful and knowledgeable. My home warranty company messed up my AC unit and he came out and quickly fixed the issue and gave some helpful advice. I will be using them moving forward for any AC issues.

Miko showed up on time and completed work in a timely manner and explained everything very well. Spent time to diagnose and repair warranty work. Very nice and competent young man.
