Cole Brennan

Cole Brennan has spent his career writing about home comfort systems, with a particular focus on how Houston's climate shapes the way HVAC equipment performs and fails. Since joining 75 Degree AC, he has worked directly alongside the company's EPA-certified technicians to research and document the diagnostic and repair processes used on real service calls across the Houston area. This hands-on collaboration allows him to write content that reflects how systems actually behave in the field, rather than generic advice pulled from manufacturer manuals. His articles cover everything from AC and heating repair to indoor air quality and system maintenance, always grounded in the practical realities of Houston's long cooling season and short winter cold snaps. Cole believes homeowners make better decisions when they understand the "why" behind a repair recommendation, not just the price tag. When he isn't writing, he's usually reviewing service reports or sitting in on technician debriefs to keep his content accurate and current.
