Why Choose a Rooftop HVAC Unit?

Commercial rooftop HVAC unitRooftop units are just one of many commercial HVAC solutions offered by Shipley Energy. A rooftop heater or A/C can have a number of benefits, most notably its small footprint. If outdoor space is at a premium in your facility, a rooftop unit lets you install a modern, centralized system without a lot of hassle.

Another benefit is that rooftop systems are naturally protected from vandalism, accidents, and other forms of damage. They’re also more accessible than other HVAC appliances, which simplifies maintenance and makes taking care of emergency repairs easy.

Along with added space savings, enhanced equipment protection, and ease of maintenance, rooftop HVAC units offer the following advantages:

Modular flexibility: Because the majority of rooftop HVAC units are modular by design, they can get added to and/or redesigned at a later time if the heating and/or cooling needs of your building change.

Decreased noise: Although new rooftop HVAC units are built to run quieter than previous models, they still make some noise when operating. However, since rooftop units are well outside the earshot of the occupants of your building, what you get is quiet comfort.

Extended life: Rooftop units come in contact with far less dirt and debris than ground level units. The result is that rooftop units tend to last longer and run more efficiently due to a cleaner operating environment.

Enhanced energy savings: With improved operational controls and energy-saving options — such as thermal wheels — new rooftop HVAC units offer significant energy savings and can accurately scale their performance up or down based on seasonal demands and building occupancy.

  • Improved security: Ground-level HVAC systems are vulnerable to vandalism. They can also become a target for thieves who attempt to steal the components. Commercial rooftop HVAC units are not as accessible, which helps to minimize these risks.
  • Easier maintenance: As with most mechanical systems, rooftop HVAC units require regular maintenance to keep them running smoothly and prevent breakdowns. Because they are self-contained packages, these systems are relatively easy to maintain. The service tech won't need to enter the building to handle the task, which will minimize disruptions to your business operations.
  • Improved indoor air quality: Many of these systems have options for humidity control, and they also provide good ventilation. Your building's occupants will breathe cleaner, healthier air.
  • Structural stability: The sturdy design of these high-quality systems enables them to withstand the elements and provide many years of reliable service. You can implement a rooftop HVAC unit installation on your commercial building with total confidence.

Our HVAC experts will be happy to elaborate on any of the benefits of rooftop HVAC units.

How Does a Rooftop HVAC Unit Work?

Rooftop HVAC units are self-contained machines that contain essential air conditioning components including a condenser, compressor, evaporator coil, and fan. When installed and operating, the unit delivers cool, low-pressure refrigerant to the compressor, which converts it to hot, high-pressure gas that then flows into the condenser coil. The metal fins on the coil absorb and disperse the heat, and the fan forces the exhaust away from the facility.

As warm air flows through the system's ductwork and into the HVAC unit, fresh air enters to provide ventilation. Air filters located above the return air ducts keep contaminants from reaching the unit's cooling components.

Besides getting the hot air out of and away from the building, the HVAC unit's refrigerant cycle creates the desired indoor temperature. The steps in the sequence are:

  • The cooled refrigerant flows through the condenser coil.
  • The liquid refrigerant converts back to a gas.
  • The refrigerant extracts heat from warm air as it passes over the building.
  • The evaporator fan returns cold air into the building.
  • The warmed refrigerant travels back to the compressor, releases heat, and expels it through the exhaust system.

The cycle repeats until the desired temperature inside the building has been achieved.

Most modern HVAC systems also have an economizer system that helps to save energy when the outside air is cooler than the air inside the building. The economizer opens an air damper that reduces the need to cool the indoor air mechanically.

Some commercial rooftop HVAC units can also provide heating. These systems typically consist of a gas heat exchanger located near the evaporator fan. Discharged return air travels over gas-fired coils, and a fan blows the newly heated air into the building.

Sizing a Rooftop A/C Unit

A commercial HVAC unit is a major investment for any facility. Choosing the right equipment requires a careful consideration of your heating and cooling needs, as well as your budget and the specific engineering challenges of your facility.

Your first step should be to determine what size system you need. Commercial HVAC units range from 25,000 to more than 250,000 BTUs, or between two and 16 tons. The more square footage your facility has, the more BTUs will be required to heat or cool it. The age of your property, the number of windows it has and the number of people who generally work in it at a given time will also factor into this calculation.

While you need to ensure a potential purchase is large enough to meet your heating and cooling requirements, a too-large rooftop HVAC unit will be prohibitively expensive to run, and will likely wear out faster.

The best way to make a smart purchase is to work with a knowledgeable professional. The Shipley Energy team has extensive experience sizing rooftop HVAC systems for commercial customers. Call us for assistance picking the right unit for you.

Rooftop HVAC Installation and Maintenance — Protecting Your Purchase

The U.S. Small Business Administration estimates 40% of the energy used in commercial buildings goes toward running their HVAC systems — so the heating and cooling of commercial spaces accounts for one of the largest expenses related to building operations. And when your HVAC system is old and/or not working properly, your heating expenses can rise substantially.

For reasons related to both budget and comfort, a rooftop HVAC unit must be kept in good running condition to ensure it delivers the performance and reliability you require of it. The best way to do this is through regular maintenance. Shipley Energy offers on-site service for any commercial HVAC customer. We’ll put together a maintenance schedule and perform routine inspections, filter changes and other service that will help protect your investment for the long-term.

We can also assist with the installation of your unit. Working on our own, or with your team, we’ll oversee the process and provide training to your maintenance staff on proper operating procedures. It’s this commitment to complete turnkey solutions that has made us a leading commercial HVAC system supplier for businesses in Pennsylvania and beyond.
