    How Do Commercial HVAC Systems Differ from Residential Systems?

    Wednesday, July 20, 2016

    Commercial services for HVAC systems and residential services work in similar ways. There are some key differences everyone should be aware of, however, especially when hiring a technician to perform maintenance or repairs. Only technicians with experience in commercial services should work on commercial HVAC systems. Without the proper experience, technicians may incorrectly repair or install the components of a unit.

    Below are three key differences between commercial and residential systems:

    1. Size: Commercial HVAC units are usually much larger than a residential unit because they are designed to serve large buildings and a significant amount of people, which requires a more complex, larger system.

    2. Location: While residential units are typically found outside and beside the home, commercial systems are positioned on the roof. There are many reasons for this placement—it removes sound pollution from the often noisy units, frees up valuable workspace, allows for easier access to maintenance and repairs that won’t interfere with daily workflow, and keeps the system safe from vandalism.

    3. Packaged or Split:
    In a split system unit there are two separate cabinets, an outdoor cabinet and an indoor cabinet. The outdoor cabinet houses the condenser, condenser fan, and compressor, while the indoor unit houses the other components including the blower, evaporator, and drainage. A packaged system has all these components contained in a single cabinet. 
    Split systems are generally more quiet and efficient than packaged units however, they take up interior space. When space is limited a packaged unit is often the better choice, especially in commercial applications where they are frequently placed on the roof. Packaged systems are more commonly used in commercial applications while in our region split systems are more commonly found for residential purposes.
