Since the State of Texas does NOT license Energy Efficiency Contractors, we as a company have made the choice, on our own, to be held accountable. That is why we have become RESNET Energy Smart Qualified Contractors. RESNET is Residential Energy Services Network (www.resnet.us) which is a non-profit corporation that sets national standards for building energy efficiency. There are a number of things that distinguish RESNET Qualified Energy Smart Contractors from all others.
