Energy Audits

A home energy audit is a useful tool to help you better understand your homes energy consumption and performance. Typically this is the first step in enhancing your homes energy efficiency, comfort level, and a useful way to lower your utility bills. A9 Green's energy audits use a variety of techniques and equipment to understand the energy efficiency of your home. We provide you with details on how to save both energy and money by determining how and why your house is inefficient and underperforming. Our auditing process consists of:


  1.  A complete inspection of the house and envelope

  2.  Several tests including insulation, air leakage, and ventilation to find problem areas and leaks

  3. Evaluation of HVAC systems, and appliances

  4. Recommendations for the best course of action to remedy the presented issues
