Home energy audit probably save you money in the long run. It can be done any time of year, but the winter is the best time for a home energy assessment, because your audit can include a thermographic scan.

Why Winter?

A thermographic inspection works by using infrared cameras or video – tools that can see light that is in the heat spectrum.

According to the Department of Energy, thermography requires “images on the video or film to record the temperature variations of the building's skin, ranging from white for warm regions to black for cooler areas.” This means if the tool shows white, red and orange colored areas on your house, that’s where the most heat loss is occurring. 

According to Keith Hill, manager, technical support, at Minnesota Air, thermography works best with a large temperature difference. “Cold weather allows the auditor a more precise view of the heat escaping your home or of the cold air sneaking in,” said Hill. “And since many people put off energy audits until warmer weather, it’s easier to schedule in the winter months.”

If you schedule a professional home energy audit it can be as simple as a walk through or as in-depth as using thermographic tools, blower doors, and HVAC equipment reports and cost assessments. The Department of Energy’s website can help you find a professional home energy auditor near you, and help you prepare for the assessment.
