DoHVAC Houston is an HVAC trade training school located at 3731 Briarpark Dr., Suite 150, Houston TX 77042. The school offers 5-8 week hands-on HVAC training programs taught by instructors with 25+ years of industry experience. Professor Juan Diaz is the primary instructor — named across multiple student reviews for patience, hands-on methodology, and genuine investment in student outcomes. The school is bilingual, offering instruction in English and Spanish, and also teaches in Mandarin Chinese. A free orientation is available before enrollment.

The hands-on training curriculum covers: basic electrical work related to HVAC systems, welding, refrigerant charging and recovery, troubleshooting techniques, and field installation practice. Students work on actual AC units set up in the classroom for live practice scenarios, and have access to commercial rooftop unit experience on the school's own roof. The stated goal is for graduates to be immediately workforce-ready, with the confidence and hands-on skills to work on real jobs from day one.

Student reviews note Juan Diaz's teaching style as methodical, patient, and focused on ensuring every student develops real competence rather than theoretical knowledge. One graduate started his own HVAC business after completing the program.

Note: One review alleges the school is not accredited and questions whether it is legally permitted to operate in Texas. Prospective students should verify current accreditation status and any applicable licensing pathway implications before enrolling. DoHVAC Houston is not an HVAC service contractor — it does not offer residential or commercial HVAC repair or installation services.
