What Types Of Commercial Air Conditioning Units Are Available For Your Business

Keeping your business cool is important for happy employees. If your current commercial air conditioning unit isn't working at full capacity and you are considering replacing it, check out these four common systems. Learn about each type to determine which is best for your business.


A split-system air conditioning unit consists of two units. The indoor unit is the air handling unit, and it contains the cooling coil, supply air fan and the expansion device. The outdoor unit is known as the condensing unit, and it consists of the condenser coil and the compressor. Instead of using ducts, the systems are connected via wires and tubes, which means it requires less work to install.

Cooling starts in the outdoor unit. Refrigerant gas is heated and then cooled until it becomes a liquid. This liquid moves through the tubes to the inner unit. The inner unit uses the cooled liquid to create cold air, which is blown into the building. At the same time, it pulls warm air out of the building. Split-system units have a high energy efficiency rating, making them one of the best ways to cool your business.


A packaged-system is much like a split-system, but everything is contained in one unit. This unit is kept outside, usually on the roof. These systems are common in larger business buildings, while split-systems are more common in smaller buildings. The process to cool your business works much like it does with a split-system, except everything is done in the same unit. Instead of blowing the cold air directly from an indoor unit, the cold air is blow through ducts, which spread the air throughout the building.

Like split-systems, the packaged-systems have a high energy efficiency rating, making them a great way to effectively and inexpensively cool your business. However, they are slightly less efficient than split-systems. This is due to the fact that they use ducts to move air. Ducts are notorious for leaking air. In fact, in homes, duct leaks allow 20 to 30 percent of the air to escape, so it's important to have your company's ducts sealed and maintained if you choose a packaged-system

Chilled Water System

Chilled water systems are a popular option for larger buildings, and they don't generate as much heat as split-system and packaged-system units. Unlike split-system and packaged-systems, they rely on water instead of refrigerant gas. The water is cooled in the cooling tower, which is located on the roof.

Once cooled, the water is ran through pipes to different areas of the building until they reach the air handlers. The air handlers work much like split-system and packaged-system units. The cold water runs over the cooling coils, and a fan blows cold air. Once the water is hot again, it returns to the cooling tower.

Heat Pump

Heat pumps can be used for both heating and cooling. They aren't as effective as other options, but they don't cost much to run. If you choose to use a heat pump just for cooling, you'll want to make sure your climate has mild summers. If you choose to use a heat pump for cooling and heating, you'll want to make sure your climate has mild weather throughout the year. Even then, it is a good idea to have a backup in the event of severe weather.

Unlike the other systems already mentioned, a heat pump doesn't generate cold air. Instead, it moves cold or hot air to desired locations. If you want to cool your building, the heat pump pulls hot air out of the building and blows it outside. At the same time, it pulls cold air from outside and pumps it inside the building. This inability to actually cool or heat the air is why it is best for mild temperatures.

Having a good air conditioning unit for your business is a must, unless you want to create an uncomfortable working environment.
