Rooftop Units

Mammoth rooftop units are a popular choice for low-rise buildings. They are available in sizes from seven to 100+ tons, and in single and multi-zone configurations. The rooftop is a logical choice for economical year-round climate control for a wide range of applications. The Mammoth RMZ rooftop is specifically designed for the replacement rooftop market, and can fit nearly any existing rooftop configuration. Our units operate either on an individual unit control or system control basis. They also function efficiently on either constant-volume or VAV distribution schemes. We offer nationwide parts and service capability.
