Thermographic Imaging Helps HVAC Services Technicians Detect Air Leakage and Thermal Defects in Building Envelopes

HVAC services technicians now have a better instrument to detect thermal defects in building structures – infrared scanning or thermography.

Thermography measures the temperature of a surface by means of infrared still and video cameras. Such tools can see light situated in the heat spectrum. Technicians can record temperature variations of the skin of a building in video or film format. The color of such surfaces can vary from white in warm areas to black in cooler regions. With the help of such images, an auditor can determine if insulation is needed or might ensure that insulation is correctly installed.

Thermographic inspections are either interior or exterior. It is the auditor’s responsibility to decide which method is expected to give the most appropriate results, depending on weather conditions. Interior scans are more commonly encountered because warm air that escapes from a building does not necessarily move in a straight line through the walls. Therefore, heat loss eventually detected in one region of the outside wall may originate at a different location on the inside surface of the wall. This is why interior surveys performed by providers of HVAC services are statistically more accurate.  Get your Aurora air conditioning unit repaired or replaced immediately.
