I always refer to John for heat load designs and advice on the higher end and more complicated projects. The best in the field when it comes to VRF equipment, designs and knowledge.

John has consistently proven to be a knowledgeable and dependable consultant. His professionalism, technical expertise, and adaptability have made him an invaluable resource for our team. Whether it’s product selection, system design, or troubleshooting, John approaches every challenge with precision and care. Highly recommend him and HVAC Mensch for any contractor or business looking for expert HVAC consulting and support.

I am a high performance home builder/remodeler in Texas Hill Country. I have used John on several projects and have been very happy with the results. My projects tend to be more value oriented and finding an HVAC consultant & contractor that will keep budget in mind has proven to be very difficult. I wouldn't call John cheap, but I do find him reasonable. He is extremely knowledgeable and I have enjoyed many conversations with him where we try to accomplish something others are spending lots of money on for much less. High performance homes all start with good design and John has become a valuable member of my design process. I can't recommend him enough.

Our company has contracted John on several of our more challenging projects, particularly those with VRF systems or complicated performance build issues. John brings an absolute wealth of knowledge and is well worth the investment for any HVAC contractor, builder or homeowner looking to tackle issues where others have walked away.

I've been working with John for years. He's an honest, professional, intelligent guy. He's my go to for difficult air quality, VRF, or HVAC problems. A true building science aficionado if you have any kind of problem with the air in your building that others haven't been able to solve this is the guy you want to reach out too. He will help you find the root cause and build a solution to help get the issues resolved. I will continue working with him for all my future projects.

HVACMENSCH provided exceptional service and resolved an airflow issue in my home. My upstairs room was much hotter than the rest of the house, and they quickly identified the problem using the right tools. They explained everything clearly so I understood the issue. I’m very impressed with their professionalism and expertise. Highly recommend!
