    Rooftop HVAC Units

    Commercial rooftop units, also known as outdoor packaged units, are an excellent choice for retrofit, replacement or new construction. Rooftop units provide energy efficient heating and cooling to your facility and are available from several of the major manufacturers, including York, Carrier, and Trane just to mention a few. We provide installation, service and repair of all makes and models of heating and cooling rooftop units.

    Rooftop Heating and Cooling Units

    Today’s rooftop heating and cooling units, from 1 ½ tons to 160 tons, offer superior indoor air quality and energy efficiency. Digital controls allow you to use building management systems, which promote efficient operation and system monitoring.
    We install, service and repair rooftop HVAC units from all of the major manufacturers, including:
  • York/ Johnson Controls
  • Carrier
  • Trane
  • Lennox
  • McQuay/ Daikin
  • Rheem
  • American Standard
  • Reznor
  • Modine
  • And many others
  • The benefits of rooftop HVAC unit are many. Commercial heating and air systems can be an eyesore, and take up a lot of space at ground level. Rooftop HVAC units are packaged systems that we install on rooftops, and tie them directly into your building’s ductwork. While this can result in lower installation costs, rooftop heating and cooling units offer other benefits as well.
    • Rooftop units are modular, meaning you can add to it if you expand or redesign your building. Depending on the size of your facility, you may have multiple rooftop HVAC units, allowing you to tailor the temperature settings for specific areas.
    • Less noise pollution. While today’s ground level HVAC units are quieter than their predecessors, they still make noticeable noise. Rooftop HVAC units are out of earshot, for the most part, making the building and its surroundings seen quieter.
    • Better security. Ground level HVAC units are a visible target for vandals. Rooftop heating and cooling units pretty much eliminate the risk of vandalism and the theft of individual parts.
    • Save space. Traditional ground level systems can take up a lot of space. Packaged rooftop units free up that space, which you can use for landscaping, additional parking, or building expansion.
    • Increased energy efficiency and performance. Commercial rooftop HVAC units come with a lot of options that allow you to optimize the unit. Those with variable air volume controls, for example, save energy by meeting airflow demands with matching fan speeds. Economizing controls, such as dampers, use the outside air to cool a building when outdoor temperatures allow it. During the summer, thermal wheels, or energy recovery wheels, decrease your cooling system’s load by transferring the heat and humidity in the supply airstream to the cooler and drier airstream in the exhaust. By using programmable thermostats in the building, you can adjust your HVAC system’s operation according to seasonal changes and building occupancy.
    Rooftop HVAC units need professional service and maintenance at least once a year to reduce mechanical problems and maintain optimum energy efficiency. Monthly and quarterly maintenance (changing the filters, checking for leaks) can be done by your building maintenance person, or you can arrange an HVAC maintenance plan with Harford Refrigeration.
