In a commercial setting, heating, ventilation and air conditioning systems (HVAC) remove moisture from the air in order to cool the building. A well-designed system will keep the building’s occupants comfortable regardless of the outdoor temperatures and humidity levels.

Chillers provide an efficient way to accomplish this goal while increasing performance and sustainability. Chillers remove heat from the air using a liquid or vapor system, keeping the facility at a constant temperature. Chillers have become an essential HVAC component of a wide variety of commercial facilities, including hotels, restaurants, hospitals, sporting arenas, industrial and manufacturing plants, and more. Chillers are available in a variety of sizes and styles that are sure to meet the specific needs of your commercial facility.

Air Handling Units

Air Handling Units work with other HVAC equipment to condition and circulate large volumes of air throughout a facility using ductwork. Air handlers are installed as part of an overall commercial HVAC system that also incorporates a chiller or a condensing unit. These units typically uses a mixture of outside air and recirculated air from the building to filter, cool, and heat. The unit directly affect the building’s air quality by addressing such issues as temperature, humidity, ventilation, mold, and bacteria.

Air handlers can provide a variety of benefits, including fresh air intake, humidity control, heating, filtration, and energy recovery. The specialists at Mason & Barry will work with you to understand the needs of your facility, as well as local codes and requirements. We will then recommend a system to address your situation. Air handlers work to move air throughout the facility, improving indoor air quality and regulating temperature.

Air Handling Units range from 15 to 1,400 tons of cooling capacity, and can be integrated with other types of HVAC equipment.
