Maintain Climate Control with Rooftop HVAC Units

Many multifamily housing structures and businesses need rooftop HVAC units to properly heat and cool apartments, offices, condos, and more. Our selection of rooftop HVAC units includes options that will help you customize the perfect solution for your heating and cooling needs.

Not only will your HVAC unit be installed by our expert team of highly trained HVAC technicians, but you can also enjoy the peace of mind that comes with knowing we’re here with 24-hour emergency service throughout the year, ensuring you always have a service professional when you need one.

Why Choose a Rooftop HVAC Unit?

Rooftop 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.

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.

“We decided to go with Shipley Energy 10 years ago because of the need to hand this task off to a reputable company that specialized in the field. Our staff is very busy with projects in house and we needed someone (local) whom we could rely on to manage both electric and Natural gas for the long- term future. What stands out the most with our relationship / partnership with Shipley is the open communication between the companies. Shipley is constantly monitoring our usages to protect us from unanticipated surprises in the extreme heat or cold temperatures of our seasons. Shipley has well documented usages for our facility and shares that information as we move throughout the seasons and contract process. Shipley strives to uncomplicate the process and is open for conversations as required. I would suspect that If you are looking for a new supplier or are unhappy with your current supplier you owe it to yourself to visit with their sales staff.”

“Springwood Hospitality began our partnership with Shipley Energy in 2013 and at that time, we were managing four hotels. By the end of 2019, our portfolio will have 13 hotels, with more opening close behind. Shipley Energy has successfully helped us manage our portfolio’s energy costs during this period of growth. They conduct regular check-ins with our team and monitor industry trends to give us the information we need to make educated decisions about our energy agreements. We have a dedicated account manager that we can go to for any questions or concerns that we have throughout the year and during our renewal they are responsive and easy to work with. I would definitely recommend that other hotel management companies’ partner with Shipley Energy if they would like a peace of mind surrounding their energy costs.”

"TecPort Partners elected to do its most recent electric supply shopping through EnergyObjective, utilizing their impressive reverse auction platform. The company was able to exceed our expectations and lock in our PPL supply at a pleasantly low 18-month price. We saw wide supplier participation, a competitive back-and-forth bidding process, and complete transparency from start to finish. The contracting process was smooth and there were no surprises. The guidance provided by the reps at EnergyObjective regarding the auction process, market timing, contract lengths, and general electricity knowledge was helpful and appreciated. We at TecPort Partners would recommend the EnergyObjective reverse auction for any electricity user looking for straight talk, competitive pricing, and overall ease in the process."

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.
