His head is much larger than the rest of the body, he has brown hair, light pink skin and brown mustache and eye brows. On top of his head he has a white circular head lamp attached to a grey and black band. Below the image of the doctor and the air conditioner is the phrase "HEAT & AIR" in stylized letters. The letters are outlined in white, "HEAT" is shaded in in red, & symbol in black and "AIR" in light blue. Below the rectangular part of the sign is a navy blue shaded rectangle with two half ovals on each end, also shaded in in navy blue. Inside the rectangular part is the phrase "DOCTOR" in upper case, white letters, with a yellow, horizontal line on either side of the word "DOCTOR", which extends partially into the half ovals on each end.
