The mark consists of a depiction of a purple seal with dark purple eyebrows, white, blue and navy blue eyes outlined in dark purple and a dark purple nose and mouth. The seal appears to be smiling exposing its red tongue and is wearing a long sleeved green turtleneck sweater and a white and silver hat with a yellow anchor in the center outlined in gold. The seal is holding its left hand above its head and is holding a silver wrench. The mark is outlined in dark purple and yellow and has shading throughout. To the right of the depiction are the literal elements "TECH-ON-DECK" written in white stylized font. Directly below is a gold banner with the literal elements "HEATING AIR ELECTRIC" written in brown font with two white circles on each side of "AIR". The remaining color white represents background and is not a feature of the mark.
