Almost every house has an operating heating and air conditioning unit, or in industry terms: HVAC. It stands for Heating, Ventilation, and Air Conditioning systems. Having central air and air conditioning units in residential houses and commercial spaces creates a demand for technicians to install, repair, and service these appliances.
Today we're going to give you a taste of some of the information you will get when taking an air conditioning repair course. This is only a brief overview to give you an introductory look at what you'll learn if you're ready to expand your skill set into the area of air conditioning.
Different Types of Systems
Not all air conditioning systems are equal. As an air conditioning technician in Ontario, you'll likely encounter a few different types of systems. To prepare you to take on these jobs, we put together a crash course explaining what the different systems are so that you are prepared to take on these jobs. There are three main types of HVAC systems: window systems, packaged systems, and central air systems. Window systems are just as they sound, and don't require a technician to work on then. The main two systems you'll see are:
Packaged Heating & Air Conditioning System
The packaged systems got their name from having an all-in-one "package" deal. Unlike split systems, the cold and hot systems are in one unit. The units can be located on the roof of a building or in a mechanical room, or anywhere close to the conditioning space.
The cool (or hot) air is distributed around the building by a blower located in the unit, which pushes the air through the ducts and helps it go throughout the building.
Central Air System
Once you finish your HVAC technician training or your gas technician training and you go into the workforce and service residential units, you'll find yourself working most frequently on central air systems. They are typically very similar to a split system, only larger in size.
They work with a cooling fan, a condenser coil, and a compressor which are housed in a separate condensing unit located outside of the house. The evaporator coil is usually housed inside an air handler, which is usually indoors.
Warm air indoors will get blown through the cold coil located inside the home, to remove moisture and heat. The heat in the air is transferred to the coil, which cools the air. The moisture in the air condenses onto the coil and collects in a drain pan, which flows outside through a drain. The warm air is pumped outside, and the temperature inside the home is maintained.
