Are you wondering why your commercial heating and air conditioning system – or your neighbor’s – is placed on the roof? This is not an uncommon location for heavy-duty commercial HVAC systems. Commercial systems are not the same as those used for residential homes. Locating them on your rooftop offers a variety of advantages, despite their seemingly odd location.

Why are Commercial HVAC Systems Placed on the Roof?

  1. Rooftop placement makes maintenance easier and minimizes disruptions.
    The rooftop environment is cleaner with less dust, debris, and greenery, minimizing maintenance. When service is necessary, your local HVAC technician will enjoy easier access to the system. Out of the way of employees and customers, ladders, tools, parts, and the noise of service and repair will not disrupt your business.
  2. Placing HVAC on the roof saves valuable space.
    Space comes at a premium. With rooftop installation, you don’t have to lose usable floor or property space. Noisy components are located out of sight and don’t interfere with property or workplace activities.
  3. A rooftop location is a more secure place for your system.
    A rooftop locale safeguards your system against the theft of valuable components, as well as damage from vehicles, falling tree limbs, and more.
  4. Rooftop units offer opportunities for improving efficiency.
    Commercial HVAC mechanical contractors in Philadelphia know rooftop units offer a wider selection of efficiency-enhancing technology. With a rooftop system, you can more easily create temperature zones within your building, allowing for better sizing of HVAC components and more efficient operation.Energy-saving technology additions are also more readily available for rooftop units, such as fresh air dampers (FAD). These flaps, located inside ductwork, allow for cool outside air to mix with conditioned air from your system. Programmed to your specifications, they enable you to vary the volume of air flowing through your ductwork. This option is now standard on rooftop installations.
  5. Rooftop systems offer more flexibility in design.
    With rooftop equipment, you can better facilitate changing needs without needing to replace your entire HVAC system. They are an ideal solution for those renting commercial or retail space, allowing you to meet the demands of new customers more easily. With a modular design, rooftop systems allow you to add or subtract units, adding heating and cooling as needed.Because you have lots of free space on your roof, it is also easier to locate units just where needed to reduce the overall length of ductwork. This not only reduces heat loss via ductwork improving performance and efficiency (less ductwork = less opportunity for heat loss) but can also reduce duct cleaning costs.In addition, rooftop units also give you the option to use natural gas for heating and air conditioning, a widely used, extremely efficient heating, and cooling solution.
