Preparing A Home for Winter – Spot Issues with Thermal Imaging to Save on Heating Bills

Making simple repairs around the home can make a significant difference in energy efficiency that will save hundreds or even thousands of dollars every winter, year after year.

For homeowners  and contractors alike, taking the time to scan a home with thermal imaging is win-win, and can be done in minutes without the need for significant investments or thermography expertise.

Here are some quick tips for conducting a basic home energy inspection.

The Colder, the Better

Ideally, the homeowner will want to have potential energy inefficiencies in the home identified and fixed before the weather really gets cold. However, the colder the weather, the easier it is to locate places where hot air is escaping, typically around doors, windows, attics, where wires and cables enter the home, and around electrical outlets.

Simply sealing gaps within these common problem areas can save the homeowner up to 20% annually on energy bills each year. According to HomeAdvisor, the average heating bill in the United States is $1,500 per year, translating to $300 in heating costs savings. For those who experience hot summers, they can expect those same winter fixes to help improve cooling efficiency during the warmer months, further compounding energy cost savings throughout most of the year.

Check the Stripping

One of the easiest places to check for potential cold-air leaks, and also to remedy, is weather stripping around windows and doors. When it gets cold outside, stripping materials tend to shrink. Having the ability to check those spots, especially on an unusually chilly day in the fall, can help uncover what windows and doors truly need new sealing materials before the coldest days arrive.


Stripping around windows and doors is a common source of air leaks.

Spot What’s Missing

If a leak by a window or door is large enough and the air is cold enough outside, one can easily feel the air leak with their hand. That’s not feasible with issues hidden inside a wall, but those problems can comprise an additional 10 to 20 percent of total home energy loss. Thermal imaging equipment is particularly adept at detecting places of missing insulation or insulation that has moved within the home, including the ceiling.

The Right Thermal Imaging Tools for Quick Home Energy Inspections

For homeowners, the FLIR ONE Pro LT makes an excellent choice. It’s easy to operate via a phone or tablet, has both a thermal and visible-light camera, and features Multi-Spectral Dynamic Imaging (MSX), which adds visible-light details to the thermal image. The additional context provided by MSX enables anyone to start hunting for air leaks and other issues such as missing insulation or other common issues that homeowners encounter, including water intrusion or common pests who build homes in the walls, crawlspaces, or even siding.

For professionals and contractors, the FLIR C5 offers a more robust form factor that can handle the rigors of a job site and regular usage. Also featuring MSX, this handheld touchscreen device can handle drops from two meters and is IP-54 rated to repel the dust, grime, and weather of all types of environments. The battery also lasts four times longer that the FLIR ONE Pro LT, offering four hours of continuous use.
