Sunreps asked you, the HVAC professional, "What is stopping your clients from replacing their old inefficient RTUs?" One of your first answers was, "The cost of screening. It often costs close to the same price of replacing the RTU itself".  We heard you.

The United States Department of Energy  ranked the invention of the transpired solar collector (aka solar ventilation pre-heaters) in the top 2% of all energy related technologies

Sunreps 307 collector technology was originally patented by the National Renewable Energy Laboratory, a division of the Department of Energy

The United States Department of Agriculture certified Sunreps' 307 collector in 2016, thus making the 307 collectors eligible for the Rural Energy for America Program (REAP)  for significant grants and loans

Sunreps' collectors are  eligible for a variety of State grants, the Federal Investment Tax Credit (ITC) and MACRS
