When the weather outside is too hot or too cold, we rely on our Heating, Ventilation and Air Conditioning Systems to keep us comfortable. If they show signs of deterioration and damage, it would be a good idea to have them checked or better yet, fixed. Fortunately, this is where the expertise of an HVAC Technician would Step In.

Job Duties

The role being played by an HVAC Technician is in ensuring that all types of HVAC Devices, like refrigerators, air conditioning units, and heaters, would function at all times especially when they are needed the most.

The scope of their work could include performing diagnostics, repairs and replacements for the parts in an HVAC system. Of course, this would require for the technician to brave extreme working conditions to make sure the unit is in working condition.

Not to mention, their work would require them to deal with refrigerant and Freon gas which could have a serious environmental effect once improperly handled. Thus, it is required the HVAC Technicians to be able to handle pressure, danger and various work-related factors.


To become a Licensed HVAC Technician, a prospective individual will have to meet a few certain requirements. First, they must have at least passed through high school and have above average marks in the field of chemistry, physics, mathematics.

In addition, a person has to have familiarization over concepts like blueprint reading, mechanics and electronics. Lastly, a person has to have a willingness to endure certain work conditions like heights and cramped spaces and possess an affinity towards safety procedures.

Education-wise, a person has to undergo formal training and education. This will involve tutelage under a recognized HVAC curriculum, on-the-job training and even apprenticeship under the supervision of a licensed HVAC Technician.

Finally, the student has to undergo certification as their final step towards becoming a licensed HVAC technician. This certification will gauge their specialisation towards certain services in the field and most of all, their competency towards rendering services. In addition, the certification process will gauge a person’s ability to deal with refrigerants which can pose a threat to the environment if not handled properly.

After the certification is received, they are now ready to provide HVAC Services for whatever client they will meet after employment.

Job duties by level of Certification

The EPA Section 608 Certification, commonly known as the Certification for HVAC Specialists, is given to anyone who has deemed themselves capable of handling, disposing and repairing refrigerants without causing problems in the environment.

There are actually four levels of certification given by the board that will determine what types of work an HVAC Specialist can take once fully licensed. We look into more details on certification here. But, in terms of job duties the differences are:

Type I Certification

Technicians with this level of certification are able to provide services to small and light HVAC devices like vending machines, window air conditioners and refrigerators for residential properties. In addition, their services are limited towards repairs and diagnosis

Type II Certification

This is granted towards Technicians who are deemed capable of handling high pressure refrigerants found in residential air conditioners, heat pumps and refrigerators for industries and supermarkets.

Type III Certification

For technicians whose job revolves around dealing with low pressure refrigerants found in chillers, getting a Type III certification is considered a must.

Universal Certification

Considered the highest level of certification for HVAC Technicians, this is granted towards technicians who have the ability to service all types of HVAC units and are capable of providing various services for them.
