Keep Your Home Cool with Thermal Troubleshooting

Summer has finally arrived and we all know what that means—hotter days are here. Spending time out by the lake or in a pool is key to cooling off, especially if you feel like your house isn’t cool enough. Don’t you just hate coming home from work, sitting down on the couch and it’s hotter than a hot skillet? Yeah, we do too. To help find these issues within your home, use thermal technology. Thermal inspections can be simply performed with the right device. Use the new Pulsar Helion monocular to detect issues from lost energy efficiency at windows, doors and poorly insulated areas that need addressing.

Pulsar’s newest product, the Helion XQ28F (PL77392), is the answer to your home’s issues with a new, more affordable, full-featured thermal monocular. The Helion XQ28F contains similar features like the rest of the product family, including audio and video recording, eight different color display settings, variable magnification, eight-hour rechargeable battery, rugged glass-nylon composite construction and ultra-reliable IPX7 waterproof. The XQ28F features WiFi compatibility with the Stream Vision app for remote viewing on smartphone devices.

How Thermal Inspections Work

Thermography is the use of thermograms to study heat distribution in structures or regions. For example, detecting cold air leaks through a window. Thermograms are a record made by a thermograph. Thermal devices feature different on-screen colors to detect heat. For example, temperature variations range from white in warm regions to black in cooler. While using a device, simply take a snapshot of the area you’d wish to survey. This will help determine where insulation is needed. Thermal devices are also great for quality control to detect if insulation was installed correctly and will save you money if it is done properly. If you’re using “black hot” mode, the insulation will appear black within the walls. Patchy areas will result in white areas being shown, meaning that it is lacking insulation.

Locating Energy Loss

Locating energy loss can be a time-consuming task but is definitely worth it if done correctly. In some instances, some areas in a house will be much hotter than other areas. The kitchen, of course, will be hotter due to cooking. Cool air escapes through any small crack causing your A/C unit to work overtime making your bill rise. Using your thermal device, scan through every room snapping pictures of every affected area. Check windows, air vents, doors, rooms and even your ceiling. From there, you can check to see if you need to install new ducts or insulation.

Air Ducts

One of your main priorities is making sure your duct connections are installed properly and working like they should. A leak can occur when one is not installed properly. Residential buildings suffer the most from an air leak through the duct system. Simply turn on the central heat, which will cause pressurized air around the duct system, and with the help of a thermal device, you can scan to see which duct is leaking.

Checking for leaks within the door and window frames is also a common practice. Sure, you can simply point a thermal device to the area affected and it will give you the answer, but sometimes testing a bit further can help you in the long run. A “blower door” can be used to measure the airtightness of your home. A blower door is a frame with a fan that fits over a door to test airtightness and airflow in buildings. It can help you when using a thermal device because certain areas that are leaking air will be highlighted in a specific color. For example, if you are using a multi-color thermal, then air leaks will be in red.


Insulation helps keep your home cool during the hot summer days. Inspecting your insulation will help you determine whether or not you’ll need to replace it or refill some areas. You can easily spot areas with missing insulation because you’ll notice an uneven pattern through the handheld thermal device. After using the thermal device to inspect your insulation, you can make your way to the attic to see how much insulation is missing or if it’s time to replace old insulation. Sometimes you are able to pull the old insulation out through the attic and refill the area, but sometimes you might need a professional’s hand to complete the task.

Keeping your home’s insulation and air flow up to date should always be a priority. The Helion XQ28F can help you find issues surrounding your home’s conservation of cool air during the summer. In the long run, you can save a lot of money before the issue becomes worse.

Do you use your thermal for more than just hunting and shooting? What alternative uses have you found for your thermal imager?
