McCullough was able to schedule my AC "second opinion" appointment for the morning after I called. Shawn showed up to my rental property promptly, did his inspection and called me twice to discuss his findings and his recommendations. I appreciated his courteous, professional advice, and will call McCullough again if I have a similar AC issue.

McCullough came responded quickly, came out to assess my H-VAC system, gave me a quote on each component separately. Sent a contract via email, scheduled the rapair quickly and came to do the work when they said they would. Responsive business.

Motor failed on electric HVAC system, called into MCCullough and was able to schedule an appointment for the next day. Desmond arrived after 30 minute notification, professional and very knowledgeable he verified problem, provided short time fix while we waited for part to arrive and rescheduled repair for following Monday. Again Desmond was very courteous and professional, changed out motor and checked system to make sure everything was in working order. As a still privately owned HVAC company in Austin wouldn’t hesitate to have McCullough to do yearly checks and repairs. Thank you.

Mitchell was so professional, and patient to address questions about our new system. Very clear and thorough explanations to me and my partner. Made programming adjustments to reduce winter heating bill and gave easy-to-follow advice on keeping the system in top shape.
