For many years, rooftop units have been the gold standard for light commercial buildings. With effective cooling and affordable pricing, why should building owners look to something new? VRF systems are growing in popularity among building owners for three main reasons:

• Personal Comfort – Commercial buildings that use a rooftop unit for cooling are set to one temperature no matter how big or different spaces. That can lead to loss of productivity and worse: thermostat wars! With variable refrigerant flow, every space gets its own temperature sensor at setpoint, so everyone is comfortable. At last!
• Energy Efficiency – VRF systems are completely variable, so your HVAC will only use exactly enough energy to meet the comfort needs of your space. By comparison, rooftop units operate at maximum levels anytime cooling is required – no matter how much or how little. So, you can expect much lower energy bills when using variable refrigerant flow.
• Simple Installation – When a rooftop unit is installed, a crane is required to set it on top of the building. Then, large spaces above the ceiling (called a plenum) must be dedicated to the ductwork that delivers cool air to the space. By contrast, VRF systems can fit into an elevator, so an expensive crane rental is not required. And similar to a ductless system, only two small refrigerant pipes are required to keep spaces comfortable. That’s great news for owners that want higher ceilings. If you’re going for an exposed look, VRF is a great choice.
