What to Expect from a Home Energy Assessment

A specially trained and certified technician will conduct the Home Assessment.*

The first step consists of the technician taking inventory of, and reporting on, the current conditions in your home, including the following:

• Health and safety check (carbon monoxide levels, moisture, and indoor air quality problems)
• Overall comfort level (cold/hot spots, indoor air quality stuffiness/stale odors)
• Air sealing opportunities
• Insulation levels
• Heating system efficiency
• Cooling system/central air conditioning efficiency, if applicable
• Domestic hot water system efficiency
• Major appliances
• Lighting

Certified technicians use a number of diagnostic tools during your Home Assessment including the Carbon Monoxide (CO) Analyzer, which is an important health and safety tool.

Your contractor will identify any potential health and safety issues during the initial assessment. They will need to be addressed before any energy efficiency improvements can be made through the program.

As long as no health and safety issues are present, the second step of the program consists of a participating contractor, using a 2-person crew, performing air sealing work that is fully subsidized by the program. This includes a before and after Blower Door Test, which measures the air tightness of a home and aids in identifying areas where air leakage is occurring. If health and safety issues have been identified during your Home Assessment, these will need to be remedied before step 2 can proceed.

What is a Blower Door?

A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. The auditors may use a smoke pencil to detect air leaks. These tests determine the air infiltration rate of a building.

How does a Blower Door work?

Blower doors consist of a frame and flexible panel that fit in a doorway, a variable-speed fan, a pressure gauge to measure the pressure differences inside and outside the home, and an airflow manometer and hoses for measuring airflow.

Step 3 will include additional, more extensive home improvements for energy efficiency.

Steps 2 and 3 can be combined into 1 visit.
