The Case for a Home Energy Audit in Trenton
Energy bills rising faster than makes sense? Cold spots in winter, hot spots in summer, or a furnace and AC that seem to run non-stop? These are the symptoms that a home energy audit in Trenton, NJ is designed to diagnose.
Our audit starts with the two biggest levers: the building envelope (walls, attic, basement, windows, doors) and ductwork. In the Mercer County housing stock — a mix of mid-century suburban, older rowhome, and newer construction — these are consistently where the biggest efficiency losses hide.
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.
Robin Rafkin — June 2024
I had called numerous companies and had numerous individuals to our house. No one could figure out the issues. Ori explained everything and fixed the issues. He and his crew are wonderful!

What’s Behind the Walls of Your Trenton Home?
A thorough home energy audit uses thermal imaging to scan every wall in your Trenton 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 Trenton 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 Trenton
Older homes in Trenton 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.
Inside a Home Energy Audit — Trenton, NJ
Our home energy audit process in Trenton, NJ:
1. Blower door test — Depressurize the home to 50 Pascals. Outside air then enters through any leaks in the envelope, which makes leak locations detectable by feel and visible on thermal imaging.
2. Thermal imaging walkthrough — Walk every room with a thermal imager. Temperature differences between interior surfaces and framing members reveal insulation gaps, air leakage paths, and thermal bridges that your eye can’t see.
3. On-site debrief + written report — Discuss findings with you live, then deliver a written report ranking recommendations by impact and cost. Most audits complete in about 2 hours.
What Happens After Your Audit?
You’ll get three things: (1) your home’s current efficiency, (2) prioritized problem areas by impact and cost, (3) specific recommendations. Your auditor walks you through fixes, cost ranges, and rebates. Under the IRA’s 25C credit, many improvements qualify for 30% tax credits, and the audit itself is credit-eligible up to $150.
