Claim This BusinessTM Air Conditioning and Heating has anchored its reputation in Round Rock for decades, with founder Thomas at the helm serving homeowners across the Texas hill country. Twelve verified reviews reflect a flawless 5-star average, and long-term clients cite relationships stretching back 30 years. The company handles installations and routine maintenance for residential and light commercial properties, with Carlos Johnson and Azucena Krobatsch noting quick turnarounds after system failures. A phone call to (512) 335-6801 connects callers directly with the crew, not a dispatcher.
Thomas distinguishes his crew through responsiveness and mentorship, running a shop where young apprentices shadow jobsites alongside seasoned technicians. Britton B credits this apprenticeship culture for consistent quality across four HVAC installations at his recording studio. The company stocks new equipment at competitive pricing, a detail Carlos Johnson highlights after a same-weekend replacement during a heat wave. Without a website to reference, prospective clients gauge credibility through the review stack alone.
Robert Bryce recounts four separate HVAC system installs over three decades, calling Thomas simply the best contractor he has ever hired. When Azucena Krobatsch called at 3:45 on a Friday with a clogged drain, Thomas advised waiting until morning rather than risking attic heat exposure during an after-hours visit, demonstrating safety judgment over sales pressure. Big Diz-ave describes Thomas as a mentor who brings apprentices to jobsites, a practice that channels experienced labor into the neighborhood economy.
9 of 12 reviews quantify multi-year or multi-decade relationships with Thomas, citing reliability, reasonable pricing, and honest assessments. Britton B and Big Diz-ave specifically name apprentices working alongside Thomas, while Azucena Krobatsch describes a safety-first advisory that prevented an after-hours attic visit.
