The mark consists of a configuration of a commercial truck with a cab trailer appearing in orange. On the side of this truck is a design of thirteen white, narrow sun rays of varying length, extending upward and outward from the upper surface of a dark blue mountain. The bottom of the mountain forms the top line of a white rectangle, outlined in dark blue, containing the wording "HORIZON" in large lettering, above the wording "SERVICES" in slightly smaller lettering. The wording "HORIZON" and "SERVICES" appears in orange block lettering with a thin dark blue border. Below the rectangle is a dark blue rectangular ribbon, framed in white lines, containing the wording "PLUMBING" in white block lettering followed by a white solid circle, followed by the wording "HEATING" in white block lettering followed by white solid circle followed by the wording "AIR CONDITIONING" in white block lettering. The matter shown in broken lines is not part of the mark and only serves to show the position and placement of the mark.
