A home energy audit is the first step in making your home more efficient. An audit will assess how much energy your home uses and evaluate what measures you can take to improve efficiency. But remember, audits alone don't save energy. You need to implement the recommended improvements. Energy Audits Unlimited provides extensive information about home improvement projects to enhance energy efficiency, lower utility bills, and increase comfort.

Progressive pricing based on Square Footage of Building

  • Residential: Residential: $300 for a building up to 3000 square feet, plus $50 for each additional 1000 square feet, or portion thereof.
    The audit includes diagnosis with the Blower Door and the Infra-Red camera. The audit will also include a visual inspection of the furnace/boiler and a visual inspection of the existing insulation.

    The report will include the results of the diagnoses, including the Home Heating Index (HHI) and the Natural Air Changes per Hour (ACHn). These numbers will have meaning as they will also have been discussed on the day of the audit. The report will also be accompanied by a list of qualified weatherization (Wx) vendors and some D-I-Y sketches of some fixes to simpler problems found during the audit.

     $325 for Blower Door test, if one is required to obtain Certificate of Occupancy for new construction. Check with your town building inspector to learn if this is required.
