hvacMENSCH

Founded by John K. Chavez, a licensed HVAC contractor and design-build professional with nearly four decades of hands-on field experience and industry education, hvacMENSCH supports building projects through a combination of contractor-performed HVAC design-build services and independent technical advisory support. Our work bridges building science, engineering fundamentals, and real-world field experience to help clients better understand system options, performance considerations, and practical tradeoffs. Although hvacMENSCH frequently operates at the advisory and owner-representation level, our perspective is grounded in licensed HVAC contracting practice and hands-on experience with installation, commissioning, and system operation, ensuring guidance informed by real-world conditions. hvacMENSCH provides system evaluation, design guidance, performance analysis, technical advisory, and owner-representation services to building owners and project teams across residential, commercial, and industrial projects. Our work emphasizes healthy indoor air, durable buildings, and HVAC systems grounded in sound engineering and real-world performance. Where required, MEP documentation is developed in coordination with appropriately licensed professionals, including Oscar Villarreal, P.E. "Crafting comfort with purpose and compassion” is more than our tagline — it’s our approach to every project. Or, as we like to say, hvacMENSCH is trying to make ethics cool again.
