Not all air conditioning units are created equal, HVAC services professionals say. Although they serve the same purpose, each of the available models has a different structure and functions in a different way.
Here is some information about the most commonly met types of HVAC devices:
- Rooftop unit – As suggested by its name, this air conditioning system is designed to be mounted on the building’s roof. The components that have the role to allow the air to enter the device are placed either vertically or horizontally, depending on the model. Rooftop HVAC units are considered among the most environment-friendly products in their category.
- Central unit – In this model, the central part is known as AHU, short from “air handler unit”. It has the role to let the air inside the device, and it is also responsible with cooling it, with the help of the so-called “evaporator coil”. Central HVAC units are considered the most complex air conditioning systems, and they are the best choice for residential complexes or single houses of big dimensions.
- Split unit – With a basic design, it includes only an expansion valve and a condenser. These parts, HVAC furnace repair Aurora experts say, are widely available and they also come at an accessible price, making the split unit easy to repair.
