The Cabinet is the outer metal or plastic housing that protects the internal Components of an indoor or outdoor unit. OLMO outdoor cabinets are built from heavy-gauge galvanized steel and finished with a weather-resistant powder coating. This ensures that your Multi-Zone condenser can withstand rain, hail, and intense UV rays. For indoor units, the cabinet is designed for aesthetics and easy access to the filters and Wall Mount brackets. A well-designed cabinet also helps to dampen sound, contributing to a lower "Decibel (dB)" rating. In PTAC units, the cabinet must fit perfectly within a wall sleeve to prevent air leaks. We offer replacement cabinets and panels if yours is damaged during a storm. Protecting the "guts" of the machine is the cabinet's primary job, ensuring long-term "Reliability." It is the first line of defense for your Single-Zone HVAC investment.
