Rooftop commercial air conditioning systems offer a number of must-have benefits to local businesses.

The first thing that business owners obviously appreciate is the manageable installation cost and relative simplicity of installing a commercial air conditioning unit capable of delivering both comfort and dehumidification.

Another benefit to rooftop air conditioning units is that, because they’re known as modular units, they can be expanded or reshaped to fit renovations to your property, more tenants or a change in your building layout.

The modular units that comprise an HVAC rooftop unit can be spread around to meet the comfort needs of those below – whether that means more heat between November and February or more dehumidified, cool air in the summertime.


Energy Efficiency and Dehumidification 

As with a window or through-the-wall air conditioner, you ideally want to calibrate the size of the space with the cooling load that you and the other building’s occupants need to feel comfortable on a year-round basis.

The cooling load is simply the amount of heat energy that you need to remove from a space – i.e., your building – to maintain a comfortable temperature for all of that space’s occupants. In layman’s terms, does it feel comfortable or do you need to up the ante?

The fact that buildings these days are more intelligently designed and better insulated means that rooftop HVAC units need to work less harder to achieve a cooling load that decades ago would have required much more elbow grease from that same HVAC unit.

Since HVAC – heating, ventilation and air conditioning – is a year-round affair, you should also know that the heating and cooling loads collectively are known as the building’s thermal load, and that this has also been improving thanks to better insulation, overhauled building designs and more energy-efficient HVAC units.

  • Energy Efficiency of HVAC Units

When the temperature is pushing up the mercury in the thermometer and your building is requiring a high cooling load that day, your HVAC unit is likely working around-the-clock to keep everyone comfortable.

This means that when your commercial air conditioner is cooling it is reducing the moisture for the indoor air and making the space more comfortable; at the same time, it is removing moisture from the ambient air involved in ventilation.


The “cool” thing about this is that modern HVAC units are made more energy efficient because they can work with the elements to save you money on your utility bills month to month. An HVAC unit’s dampers – which are a type of economizing control built into your unit that can save you a lot of money over the long term – actually work with the outdoor air surrounding your building to naturally lower the temperature inside.

Energy recovery wheels, or rotary heat exchangers, can also lower your cooling load in a novel, money-saving way. Your commercial air conditioning system’s overall cooling load can be effectively lessened by a process whereby the supply heat and humidity is transferred to the cooler, less humid air-stream in the exhaust.

On top of that, adjustable air volume controls and programmable smart thermostats can help you change fan spans and temperature settings on the go to meet the dynamic energy demands of your building.


Simple Installation and Upkeep 

The same factors that make a rooftop HVAC unit easy to install, upgrade or move around according to your changing needs makes the unit simple to maintain.
