  • Blower Door Test: This test measures the extent of air leaks in your home by creating a controlled pressure difference and measuring the airflow. It helps identify areas where air is escaping or infiltrating, contributing to energy losses.
  • Infrared Thermography: Using an infrared camera, our auditors can detect areas of heat loss or air infiltration, which can indicate insulation deficiencies, air leaks, or issues with the HVAC system’s ductwork.
  • Combustion Safety Testing: This testing ensures that combustion appliances, such as furnaces and water heaters, are operating safely and efficiently, without posing any health risks due to carbon monoxide or other hazardous byproducts.
  • Duct Leakage Testing: Our auditors may use specialized equipment to measure the amount of air leakage from your HVAC system’s ductwork, which can significantly impact energy efficiency and indoor air quality.

4. Energy Modeling

Based on the collected data, our energy auditors will create an energy model of your home. This model simulates your home’s energy consumption patterns and helps identify areas for potential improvements and cost savings. The energy model takes into account various factors, such as your home’s construction, insulation levels, HVAC system specifications, occupancy patterns, and local climate conditions.

By analyzing the energy model, our experts can predict the potential energy savings and cost reductions that could be achieved by implementing specific recommendations.

5. Recommendations and Action Plan

After analyzing the data and energy model, our experts will provide you with a detailed report outlining their findings and recommendations. This report may include suggestions for:

  • HVAC System Upgrades: Recommendations for replacing outdated or inefficient furnaces, air conditioners, or heat pumps with newer, high-efficiency models.
