Pros and Cons of Rooftop Commercial HVAC Systems

There are many different types of HVAC systems to choose from. From ground-based units to window frame boxes to rooftop HVAC units, there is a solution for every type of building and situation. When it comes to commercial HVAC, a rooftop unit may be the best choice considering the efficiency and lifespan of the unit.

Here are some pros and cons of commercial rooftop HVAC units to help you decide whether this is the right option for your building.

What is a rooftop HVAC unit?

First of all, let’s start by defining what we mean by rooftop HVAC unit. A commercial HVAC rooftop system is a simple, compact, all-in-one heating and cooling unit that is designed to be installed on the roof of a commercial building. These are often found atop shops and small commercial buildings and provide cooled or heated air to the entire building via distribution in air ducts.

These units are engineered to be weather resistant, including in extreme heat and freezing conditions, through rain, snow and wind. These units are entirely self-contained and are not connected to a broiler, furnace or external air conditioner.

Pros of a rooftop unit

One of the best things about rooftop HVAC units is that they are entirely self-contained. This simplifies things during installation as well as for maintenance down the road.

Another benefit is that they are located away from customers and employees, which helps avoid many potential safety hazards. The location also helps lessen the audible noise made by the unit—it’s hard to hear a machine whirring from inside the building!

Finally, its location on the roof helps keep it safe from theft, damage or vandalism. It will also stay cleaner and out of harm’s way, which will go a long way toward increasing the lifespan of the unit and lessening the amount of maintenance it will require.

Cons of a rooftop unit

While they may have many benefits, there are also some things to be aware of regarding rooftop HVAC units. For one, the units are quite heavy, so it’s important to make sure your roof and roof membrane will be able to withstand this over time.

It’s also important to make sure the installation is done by experienced professionals. If it’s installed in a low spot on the roof, for example, water may pool up from rain or snow, and this can eventually damage the roof underneath the unit.

Since it is installed in a place that is away from normal foot traffic, it may be easy to forget that the unit is even there. But it’s important to remember to check on it regularly and keep up with scheduled maintenance to ensure it continues to work properly for as long as possible.
