HVAC (Heating Ventilation and Air Conditioning) Systems

HVAC systems are crucial to the regulation of temperature, ventilation and cooling in residential or commercial areas. They are essential for keeping environments safe and comfortable, especially in Ontario's scorching summers.

Are you sure that your furnace and air conditioner are separate units? Find out more about how these two systems are interconnected through our hands-on program.


A system that regulates airflow, temperature, ventilation, and air conditioning. The air filters are responsible for maintaining the comfort of occupants by removing pollutants such as toxins, fumes, and pollutants.

These systems can be centralised or decentralised and operate through a network of ductwork and pipes to circulate air throughout the building. In some systems, air is drawn in from outside and circulated through an filtering unit. In other systems it is heated or chilled in a central plant before being circulated throughout the building.

The HVAC department has the responsibility of maintaining, repairing, and upgrading all heating and ventilation systems on campus. In addition, they provide technical support for equipment such as Johnson Controls Building Automation System.

As part of the Heating Ventilation and Air Conditioning program at Waubonsee, students participate in a broad, hands-on program that includes labs to assist them in understanding the way in which lecture material is used in real-world situations. Students can also choose elective classes like industrial controls and wiring to help them develop the skills needed when they start working on their equipment.

Students who earn the two-year Associate Degree in Heating, Ventilation and Air Conditioning or one of the professional certifications are qualified to work as installers technicians, or building maintenance craftsmen. They can also pursue a Bachelor’s degree.

Despite the fact that a lot of people assume the term "HVAC" stands for just "air conditioning," it actually refers to a complete system that's used to regulate and monitor conditions such as humidity, temperature and air quality, the supply of outside fresh air to control carbon dioxide and oxygen levels as well as draught or movement ventilation. HVAC is only effective when it combines these components. It is true for any application, from residential homes to industrial buildings like power plants, office buildings, and ocean vessels. They all require an efficient HVAC system.


Ventilation is a process that involves providing new air into a structure, and then removing dirty or old air. It's not the same thing as air-circulation, which just moves air within a building and doesn't provide fresh air.

ASHRAE, the American Society of Heating and Air-Conditioning Engineers (or ASHRAE), defines ventilation as adding "clean outside air to occupied spaces to achieve a satisfactory level of indoor air quality."

When people hear the term ventilation, they often think of HVAC systems. However, there are other types of ventilation systems. Natural ventilation is the most popular type of ventilation. The most common way to ventilate is by opening the windows and removing stagnant air. This method of ventilation works well in mild climates.

The second type of ventilation used is mechanical. This is done by an air-handling unit (commonly called an HRV, or heat recovery ventilator), which filters and warms incoming air prior to distributing it in a home through ductwork. The system can also reduce humidity and regulate temperatures in the entire house.

Modern buildings combinemechanical ventilation with natural ventilation. The HRV provides the most efficient method of ventilation in buildings. It ensures that stale indoor air is continuously exchanged with fresh air.

Ventilation is crucial for a variety of reasons that include eliminating odors and moisture from the home, as well as getting rid of pollutants such as VOCs (volatile organic compounds) which are released by certain household cleaning products, paints, and pesticides. The chemicals in the home can cause problems if they are not ventilated properly.

Ventilation occurs in many homes naturally due to a variety factors. Temperature changes and the passage of people by doors and corridors are some examples. However, this type of ventilation is uncontrolled and often inefficient. A professional will evaluate a home’s indoor air and recommend an appropriate ventilation system. There are many different mechanical ventilation systems. Some are better suited to hot or humid climates while others are better for cold climates.

Air Conditioning

HVACR service people who are successful enjoy the satisfaction that comes from improving health and comfort. The person is comfortable using their hands and has a good sense of spatial awareness. They might also enjoy the challenge of figuring out how to make equipment work properly, even when it's old and worn.

HVACR service technician mustknow about a wide range mechanical systems. This includes fundamentals such as electrical wiring, ducting system layout and designs, furnaces refrigeration and thermostats. Also, they should know the basics of airflow ventilation and moisture control, as well as how these relate to heating, cooling, and Heating Ventilation and Air Conditioning ventilating a room.

They must also stay up to date with the latest developments in the field of environmental engineering to ensure that they can offer the most effective solutions to their clients. ISO 16813 - 2006 is a new standard that provides guidelines for designing healthy, comfortable buildings.

It is best to learn on the job by working with someone who is experienced in the HVAC industry. You will find that many employers will cover the cost of your training when you work as an apprentice for an experienced technician. You can also enroll in an apprenticeship offered by your local union or an education and certification agency.

Only an associate degree can lead to a career as a HVAC technician. This degree prepares you for a career in technical expertise, as an installer technician, building maintenance craftsman or service technician. You can also pursue Bachelor's degrees in HVAC Engineering.

Our two-year program provides a great opportunity to build the skills, knowledge and work-related attitude that are required to work in today's Heating Ventilation and Air Conditioning industry. This program will give you the foundation for a four-year bachelor's in HVAC engineering. You may work for a HVAC or Refrigeration Contractor or Energy Company, or in the HVAC Department of large corporations.


The HVAC industry provides many career opportunities. The HVAC sector is growing quickly as newer and more environmentally-friendly technologies are introduced. People with higher skills can expect a better earning potential and more job security. Keep up to date with the latest developments in your field. This could lead to greater opportunities and satisfaction for you.

As a first step, complete an HVAC vocational program. You will then learn from a senior technician. After you have gained experience and expertise in certain areas, you can decide where to focus your efforts. Some of the most popular choices are commercial and residential service, indoor quality and repairs or replacements.

HVAC careers can be rewarding and fulfilling, especially for people who like to help others. HVAC technicians face new challenges and projects every day. They will find their work stimulating and exciting. It is also a highly competitive industry, with a range of job opportunities and a high wage.

When you've gained the necessary experience in HVAC, it could be the perfect time to move into a management position. This is one of the most rewarding careers, since you will be able to oversee all aspects in your company and help develop new staff. Many of the people who take on this position have worked as technicians in the past and have the skills and knowledge necessary to make a successful career transition.

HVAC technicians can choose to start their own business if they have the experience. This can be a very profitable and rewarding choice, as it gives you the freedom to set your own hours, be your own boss, and control the type of projects you take on. Prior to starting your own business, it's important to have all the resources and knowledge you need.

HVAC technicians who have previous experience may also consider a career in teaching. This is a good career for people who want to give something back to their communities and help new technicians get started. Many instructors are experienced in the field and can offer useful advice to those just starting out. They can help develop curriculum and training materials for continuing education.
