What Our Clients Say
Saima Faiz — October 2024
I recently contacted Local Energy Audits for help with a suspected duct leak. From the start, they asked all the right questions and even requested pictures to better understand the situation. Based on the information I provided, they recommended a specific service, which, surprisingly, they didn’t even sell. They didn’t charge me anything for their time, and the advice they gave was invaluable. Their honesty, professionalism, and genuine desire to help really stood out. I highly recommend them.
Max Young — September 2024
Frustrated with my high electric bills — despite an efficiency drive in lighting and appliances — I suspected HVAC was to blame but didn’t know where to start. Research suggested an energy audit, and I’m very happy I chose Local Energy Audits. Ori was extremely professional, thorough, and on-time. After the blower door test, he walked every room with me, patiently reviewing leaks and possible fixes. Particularly given the new federal tax credits, I found the price extraordinarily reasonable. Highly recommend.

What’s Behind the Walls of Your Hamilton Township (Mercer) Home?
A thorough home energy audit uses thermal imaging to scan every wall in your Hamilton Township (Mercer) home. Cold spots in winter (hot spots in summer) often indicate cracks where conditioned air escapes. Your auditor also physically inspects windows, doors, rim joists, attic hatches, and recessed lighting. In older Mercer County homes, these transitions are where the biggest efficiency losses hide.
What Tests Are Included in a Home Energy Audit?
A blower door test measures total air exchange by depressurizing the home to 50 Pascals. The resulting ACH50 tells you how leaky your Hamilton Township (Mercer) home is.
A duct leakage test is an optional add-on measuring ductwork air loss separately. It’s recommended for Mercer County homes with ductwork in attics, crawl spaces, or unconditioned basements.
Energy Audits for Older Homes in Hamilton Township (Mercer)
Older homes in Hamilton Township (Mercer) typically have significant energy inefficiencies — outdated insulation, failed window seals, missing attic air sealing, leaky ductwork. Without a systematic audit, it’s nearly impossible to figure out where to focus improvement dollars. With an audit, you know exactly what matters most for Mercer County housing stock.
