Modern rooftop HVAC units are available in higher efficiencies (SEER and HSPF) than other types of commercial HVAC systems. This means they can save you money on energy bills over time.

You might be thinking, “but the roof isn’t easy to access!” Don’t worry, that’s not quite what we mean. Our professionals can easily access the units without walking through and around your workspace to work on them.

These units also have more ventilation options available, which can improve indoor air quality. This is especially beneficial for businesses with employees who spend a lot of time indoors.

Understanding Commercial Units

Commercial units are self-contained, also known as package units, which keep everything in one place, including the compressor, evaporator, condenser, and fan.

This design makes them simpler to locate on rooftops where space is plentiful, but real estate may come at a premium price.

In contrast to split systems, which place the compressor and condenser in a separate unit from the evaporator and fan, package units are built for heavier duty in commercial applications.

Commercial units are often preferred because they don't take up valuable interior space and can be repaired and maintained during normal business hours without disrupting operations.

AC Units Are Similar

Air conditioning is air conditioning, and the fundamental physics behind it remains the same whether you're cooling a residential home or a commercial building.

The method of operation is the same - compressed refrigerant cools air moving over special coils through a cycle of expansion and contraction.

In fact, the actual difference between rooftop cooling units and other systems is that they are self-contained, also known as a "package unit", which keeps everything in one place.

Package units make it simpler to locate the AC equipment for buildings where real estate may come at a premium price, but roof space on an existing structure is plentiful.

The key difference is not in the operation, but in the design and purpose of the unit, which is built for heavier duty in commercial applications.

Rooftop units are often preferred for commercial use because they don't take up valuable interior space, and they can be repaired and maintained during normal business hours without disturbing business operations.

Operational noise is also outside, which contributes to a quiet indoor environment.

The capacity of commercial units is also much higher than residential units, with some commercial units having capacities of up to 50 tons or more, which is far beyond what a residential unit can handle.

How to Size Units?

Sizing commercial rooftop units requires careful consideration of factors beyond just raw power. You may need to spend more time thinking about what size to purchase.

The weight of commercial-grade units is a significant concern, and it's essential to select a spot that can support the weight without causing structural damage. Air conditioners are heavy, and commercial-grade units even more so.

Information about your specific cooling needs will also inform your choices regarding the size and power of the unit. Answering these questions alone can be a recipe for problems.

Seek a reputable contractor to help you navigate these considerations and make informed decisions.

HVAC Systems

Commercial rooftop air conditioning units come in a range of options, including zoned rooftop systems and intelligent VAV systems. These systems are ideal for small buildings and can increase comfort and energy efficiency while simplifying operation and maintenance.
