The mark consists of A stylized black-and white graphic design featuring the text "CITY H.V.A.C." in uppercase letters, arranged in a semi-circle at the top of the design. The letters are bold and slightly destressed, giving a rugged, industrial appearance. Below this text, there is an illustration of two pressure gauges commonly used in HVAC systems, depicted with circular dials and needles, positioned side by side with a sight glass in the center of the manifold. The gauges are detailed with internal markings and a central mounting structure, adding a technical element to the design. Crossing diagonally over the gauges are two tools: a large open-end wrench on the left, angled from the bottom right to the top left, and a welding torch on the right, angled from the bottom left to the top right. The wrench has a detailed handle and jaw, while the torch includes a cutting tip at the top and two fuel ports at the bottom. Both are rendered in a bold, outlined style. The tools intersect at the center of the gauges, creating a focal point that emphasizes the HVAC and refrigeration theme. At the bottom of the design, a ribbon-like banner stretches horizontally across the composition, with the words "REFRIGERATION" in upper case letters centered within it. The banner has a slight curve and is adorned with decorative, pointed ends that flare outward, adding a classic, vintage touch to the overall design. The entire logo is rendered in a high contrast black-and-white color scheme, with thick outlines and minimal shading, giving it a clean and bold appearance suitable for branding purposes. The logo is adaptable in black or white for both black and white backgrounds.
