When you invest in an AC system for your home or business, you want to make sure that the one you buy keeps you cool, comfortable and is also cost-effective. Given that there are so many air-conditioning options out there, it’s important to know the different types of symptoms and how they work so that you can decide what type is right for you over the long-term.
Whether you have to get an AC system because your older one is not working as it should, or you want to add one to your new space, this overview of the different kinds should point you in the right direction, and purchasing decision
Variable Refrigerant Flow (VRF) Systems. In recent years, the VRF air conditioning system has become a more common choice in households and commercial spaces across the United States. Typically, you can find this kind of AC system in city townhouses, restaurants, and retail stores. In this type of AC system, refrigerant cools the air through indoor fan coil units and outdoor condenser units. Variable speed compressors are what allow this type of system to run for the current conditions, and the design allows for customized comfort in a space thanks to its ability to have different individually-controlled zones. Advantages of the VRF system include consistent cooling, quiet operation, lower energy conception, efficient design and a longer life span.
Variable Air Volume (VAV) Distribution System. Instead of refrigerant, this type of AC system uses chilled water to eliminate heat from the air in a space. Found in larger buildings such as high rises, this type of AC system typically sources its chilled water from a larger chill unit usually in a mechanical room or basement to cool the building in its entirety. Advantages of this type of AC system include more accurate temperature control, lower energy consumption by the fans and less fan noise, to name a few.
*Rooftop Packaged Units. The RTU unit is typically an HVAC system installed on the roof. Not only does it provide cooling, but also heating and ventilation for single-story spaces such as a warehouse, big-box stores and shopping center. The main advantage of this kind of air-conditioning system is that it is easy to install.
Ducted Split Systems. Often found in suburban homes, apartment buildings and commercial space, this type of AC system also features access to a mechanical room or outdoor space. Made up of a compressor and condensing unit, as well as an evaporator coil and air handling unit, this kind of air-conditioning system has quiet operation and has the ability to cool air in different spaces of a building. A plus of this AC system is that it has the ability to remove humidity.
Ductless Mini Splits. Used for contained spaces, such as a room addition, this smaller system do not require ducts, and make for easy installation and operation. The ductless mini split AC system uses an indoor/outdoor system comprised of a conduit, refrigerant and electrical lines. This type of AC system does not work well with cooling large spaces.
Packaged Terminal Air Conditioner. Installed through the wall of a building, this type of air conditioning system resembles an air conditioner that you can fit in the window, but it is not. If you have stayed in a hotel, you have probably seen this kind of system. They are are ideal for apartments and not other spaces given that they are noisy, cycle on and off, and is only able to cool one room.
