We really needed help from McCullough in the past. Ever since we take advantage of the service every 6 months on the affordable monthly plan. Special thanks to Blake! I’ve trusted McCullough for over 20 years and highly recommend them.

Guillermo provided excellent service by quickly diagnosing the issue with my AC and completing the repair efficiently. He was professional, courteous, and took the time to clearly explain everything while ensuring the work area was left clean and the system was working properly.

Great experience getting our AC units checked for use this summer. Miko, the technician, was on time, very thorough and informative as to what he was doing. He is a credit to the McCullough service team.
