Our story
Built by Tracy O'Brien. Carried by the crew.
O'Brien was founded and is led by Tracy O'Brien, but the business is bigger than one person. It is a trained crew of technicians and field professionals handling AC repair, installation, maintenance, renovations, additions, and build-outs with the same expectation for clean work.
Tracy's background as a professional fighter shaped the company culture without turning the company into a personality brand: prepare before pressure, stay composed when the job gets difficult, and finish with accountability.

The crew
The crew that shows up
The crew arrives prepared with the right tools, clear communication, and the skills to handle whatever the job calls for — diagnosing an AC fault, installing a system, or running construction work. The standard is the same every time: respect the property, explain the work, and deliver a finished result.
From no-cool calls and full system installs to additions, renovations, and build-outs, the team approaches every job with preparation and accountability.

Clean work matters. We respect your space and leave it better than we found it.

O'Brien's name is on the result. We stand behind our work.
