AWC Energy
AWC is a leading energy services company that provides a full compliment of services. We offer consulting services, general contracting, full scale integration, installation, sustainability services, and cost-effective energy solutions for commercial, industrial, residential, retail and non-profit customers.
"Lomont and his team were great to work with, simply professional, knowledgeable and so accommodating. I hired him based upon an energy audit we had done by another company. He basically "cleaned up their mess" since they did not do a thorough report in order for us to get our energy rebate etc. He went above and beyond the scope of what we hired him to do, always with a friendly greeting and smile. He reached out to the appropriate agency to push to get the credits we were due and did work that should have been done by the energy audit company. I highly recommend Lomont."
