November is one of the best times of the year to carry out a home heating thermography survey. As outdoor temperatures drop and heating systems begin operating regularly, the thermal contrast needed for accurate infrared diagnostics becomes ideal. This article explains why late autumn conditions help reveal insulation defects, air leakage paths, and heat loss within the building envelope. Discover how professional thermography surveys conducted under Level 3 supervision can provide valuable insight into building performance before winter energy demand peaks.
