About Castillo Service A/C & Heating
Castillo Service A/C & Heating has maintained a presence in Austin for more than fifteen years, building a loyal customer base through consistent, reliable heating and cooling support. The company holds a perfect 5.0-star rating across three verified reviews, with customers highlighting the technical skill and approachable demeanor of its service team. Operating throughout Austin and surrounding communities, Castillo serves residential homeowners seeking both routine maintenance and emergency repairs.
What distinguishes Castillo Service A/C & Heating is their commitment to removing friction from the replacement process. When customer James Benavides needed a new cooling system, owner Willie managed the entire City Energy Weatherization program enrollment and handled all permit paperwork, communicating directly with the bank to simplify the experience. The company also provides complimentary portable AC units to customers facing system failures, ensuring comfort while scheduling permanent repairs.
Technicians Willie and Floyd emerge repeatedly in customer feedback for their responsiveness and diagnostic precision. When Emily Barringer's heating and cooling system stumped three previous contractors, Floyd arrived and identified the problem within hours. During a brutal Texas heat wave, Willie traveled to James Benavides' home the same day he received the service call, delivering a portable AC at no charge so the family could remain comfortable until permanent repairs could be scheduled.
What Customers Say
All three reviewers awarded five-star ratings, with two explicitly naming technicians Willie and Floyd. Both mentions praise these technicians for arriving same-day during heat-related emergencies and for solving problems that other contractors could not resolve. The consistency signals a service team that prioritizes rapid response and technical competence.
