About Sunreps Training

Sunreps teaches HVAC professionals, contractors, building engineers, mechanical engineers and solar enthusiasts how to build and install the most efficient solar air preheaters in the world.

Our system — the Fabric Transpired Solar Collector System — connects directly to rooftop HVAC units, needs no electricity, and can be built with local materials and hand tools.

Training covers design, fabrication, installation, and testing.

Licensed HVAC pros and contractors can earn microlicenses to build and install using our patented system.

Non-licensed individuals can learn to fabricate and test, but must partner with a licensed contractor to install.

Each collector produces 2–5 therms per square foot per heating season. (RETScreen data) — delivering real energy savings and measurable carbon reduction.

This is solar HVAC made simple, scalable, and local.

Adventure in design

    Sunreps systems adapt to nearly any building:
  • RTUs on flat roofs
