So, if you’re thinking about whether HVAC is a good career choice, you’ll find out everything you ought to know about a career in HVAC in this article.

What is an HVAC System?

HVAC stands for Heating, Ventilation, and Air Conditioning, and refers to the technology and equipment used to regulate indoor environmental conditions such as temperature, humidity, and air quality. An HVAC system is designed to provide thermal comfort and acceptable indoor air quality for residential, commercial, or industrial buildings.

Here are some of the key components of an HVAC system:

  1. Heating: This component of the HVAC system provides warmth to the indoor environment by generating and distributing heat. Common types of heating systems include furnaces, boilers, and heat pumps.
  2. Ventilation: Ventilation systems in HVAC work to exchange stale indoor air with fresh outdoor air. This process removes pollutants and ensures that there is adequate oxygen in the indoor environment. Ventilation systems can include mechanical ventilation, such as air ducts, or natural ventilation, such as windows.
  3. Air Conditioning: The air conditioning component of the HVAC system provides cooling and dehumidification to the indoor environment. Common types of air conditioning systems include central air conditioning, window units, and split systems.
  4. Thermostat: The thermostat is the control center for the HVAC system. It allows users to adjust the temperature, set schedules, and control the heating and cooling functions of the system.

How Does an HVAC System Work?

The HVAC system performs several functions which are related because they both make sure the home has a moderate temperature. The HVAC system has eight parts, which include:

1. Air return

This is the first process of the ventilation cycle. In this cycle, the system first takes in air and filters it. Then it sends it to the primary system, and this is when we receive the air. Always make sure your system and filter are clean for clean air.

2. Filter

It is the second process of the ventilation cycle. Here, the air passes through to make sure it is clean and conducive to the dominant system. Always clean it properly and change it based on the time given by the HVAC technician.

3. Exhaust outlet

Another part of the system is the exhaust outlet. Here, the exhaust created by the heating system is eliminated through the chimney or vent stack. Keeping the vent spaces free is good for the house and it should be maintained annually.

4. Ducts

This is the pathway where heated or cooled air goes through. Maintenance is key to keeping all these up and running. And it should be cleaned every 2 to 5 years.

5. Electrical elements

This is the most important part of the entire system. Anything that happens to the HVAC system starts from the electrical. A technician should always be available to make rounds just to make sure there are no issues with the complete system.

6. Outdoor unit

The outdoor unit is the part of the system that makes sure that the fan outside functions well to provide good airflow. If anything hinders the outdoor fan, then it will obstruct the flow of air into the house.

7. Compressor

The compressor is part of the outdoor unit and it makes sure that the air that passes through the pipe is cool.

8. Blower

The blower takes in warm air through the outdoor unit. If this air moves well then the system will be good. 

What Does an HVAC Technician Do?

HVAC technicians work on HVAC systems in residential buildings and commercial buildings. Their work involves installing, repairing, managing, and maintaining heating, ventilating, air conditioning, and refrigeration systems.

Connecting wires, welding pipes, testing electrical circuits, reading blueprints, testing for pipes leak, etc are also part of the tasks associated with HVAC technicians.
