Ryan was great. Knowledgeable, professional, timely and friendly. Got the service I requested with no other add ons. He offered a great optional estimate that was very helpful. Will definitely be working with McCullough again.

Everyone I’ve worked with has been friendly, professional and competent. They say what they’ll do and do what they say…and if there’s a problem will work to resolution.

The technician was courteous and professional and answered all my questions. My only gripe is with the scheduling of the company. I wish they could better narrow down arrival time to either morning or afternoon. Miko did a great job of not only doing the maintenance and upgrade (added some refrigerant and a quick start kit) but explaining everything he was going to do.
