• Note any obvious areas such as windows, doors, or HVAC systems that will require additional focus. The more specific you can be, the better the auditor will be able to address your priorities.

• Make sure you have access to areas you need to inspect. Remove any furniture or belongings that block attic hatches, crawl spaces or basement areas.

• Open curtains and blinds, and ensure windows and doors are closed tight to test the airtightness. Additionally, ensure that vents, ducts and systems, such as water heaters or furnaces, are easily accessible.

Steps To Conduct A Home Energy Audit

A comprehensive home energy audit is the best, most systematic approach to identify energy inefficiencies and improve HVAC energy efficiency. Here’s a breakdown of the steps involved.

1. Schedule A Professional Inspection

If you need to book a professional energy auditor, that’s a key first move. A qualified expert comes equipped with the best tools. With devices like gas leak detectors and carbon monoxide detectors, auditors can do a complete evaluation.

They can identify problems that are difficult to detect, like concealed air leaks or outdated appliances. It’s a good idea to schedule the inspection when you can be home to provide access to spaces like the attic, crawl spaces, and basement. This is important for the auditor to get an idea of the best ways to improve your HVAC system and other energy-related areas.

2. Perform A Blower Door Test

A blower door test detects air leaks by depressurizing your home and measuring the airflow. It shows you any drafty doors, windows, or energy-wasting vents that you have in your home.

After the test helps you find leakage points, the auditor will recommend sealing them to improve insulation and save on energy bills. For instance, addressing leaks in just one window could save a homeowner hundreds of dollars a year.

3. Use Infrared Cameras For Detection

Infrared cameras can show a difference in temperature, assisting auditors with locating areas with little to no insulation in walls or ceilings. Onsite with a professional, thermal imaging works best to identify heat loss in the colder months or cooling inefficiencies in the summer.

Including this step helps make sure you don’t miss any insulation issues, so this is a great step to add to the audit process.

4. Analyze Audit Results And Recommendations

The last step is going through your auditor’s report, which should lay out your findings and prioritized recommendations. Even relatively simple upgrades, such as replacing incandescent light bulbs with LED bulbs or insulating hot water pipes, can offer big energy savings.

By taking action on these discoveries, homeowners stand to benefit from significant savings on utility bills and a reduced carbon footprint.
