What Does an HVAC Career Entail?

As an HVAC technician, that is a heating and air conditioning mechanic, you’ll install, troubleshoot, and repair heating and cooling systems, including domestic refrigeration systems and commercial refrigeration systems. These skilled trade professionals may deal with heating, ventilation, air conditioning, and refrigeration technologies. Customers could be homeowners, business owners, or government entities. As an air conditioning mechanic or HVAC technician, you’ll diagnose problems with old-fashioned mechanical control systems and newer programmable control systems after asking the customer a series of questions regarding the issue. Once you have that information, you can inspect the unit and attempt to pinpoint the issue. Once you’ve determined the problem, you present the customer with a solution and an estimate for the cost of the repair, whether than includes simple maintenance or replacement of all temperature control equipment. If the customer agrees, you order parts as needed and start to repair the unit. You might also be called upon to help a customer determine the right size unit for their home. This is done by examining the layout of the home, finding out which rooms will be connected to the system and matching this criterion with the overall climate surrounding the home.

Various excellent employment opportunities throughout the HVAC industry require certain industry certifications if you expect to get the job. Many of these industry certifications are available only through the Environmental Protection Agency(EPA), which requires hands-on training and the passing of exams. Type I covers small appliances, heating and air conditioning technology, and domestic refrigeration systems. Type II, HVAC-R, covers high-pressure appliances, heating, air conditioning, and refrigeration technologies. Type III is for low pressure appliances and chillers. And the Universal certification covers all of the above.


Components of A Successful "HVAC Career"

Once you earn an Associate of Applied Science in Heating, Ventilation, and Air Conditioning (HVAC-R), you’ll be ready to work for companies that offer HVAC-R services. Contractors may need a refrigeration & HVAC technician for new construction and renovations that are incorporating new heating, ventilation, and air conditioning systems. You’ll also find work repairing and replacing existing equipment in both residential and commercial refrigeration settings. Depending on your geographic location, the predominate system can vary, so being knowledgeable about the entire HVAC system is ideal because it makes you more versatile than someone who knows how to fix air conditioners or furnaces but not both.

How to Become an HVAC Technician

What Does an HVAC Technician Do?

HVAC_technician_do HVAC technicians install and repair heating, venting and air conditioning units. They assist with new construction by installing HVAC units and wiring, and they also troubleshoot, repair, and replace existing systems. HVAC technicians work in both commercial and residential segments and are knowledgeable about the requirements of each. HVAC technicians also conduct routine inspections for the HVAC systems and their wiring to ensure the system is in good condition and in compliance with pertinent laws.

What is the Difference Between HVAC and Air Conditioning?

The difference between HVAC and air conditioning is that an HVAC system is more complex. With an air conditioner, you are dealing with a unit used to cool a home during warm months. The unit might be small, fitting in a window; or large, installed outside the home. A Heating, Venting, and Air Conditioning unit (HVAC) not only provides air conditioning, but heating and ventilation as well. The air conditioning and heat are distributed throughout the structure through a series of vents that go to each room. The HVAC system is generally a larger unit that is installed outside the home, either in a side or back yard.

Trade School Requirements

To apply for admission to a HVAC training trade school, a student should have a high school diploma or GED. Depending on the institution, an ACT or SAT exam score might be required.

Typical HVAC Certifications Needed

HVAC_technician_certifications_needed Certification requirements generally vary by state, but there is one certification that HVAC technicians who work with refrigerant recovery and recycling must go through. If they are working with refrigerant, because of the materials involved, they must complete and pass an EPA-approved training program. The Section 608 Refrigeration Recycling Rule that was added to the Clean Air Act of 1990 requires all HVAC technicians who work with CFCs know the rules of compliance to protect the environment, such as leak repair compliance, recovery cylinders for dangerous materials, and ozone depletion.

Academic Standards

Students enrolled in an HVAC training degree or certification program will have to demonstrate understanding of the courses taught by achieving passing grades in all required classes, including major classes and general requirement courses. Once all courses are taken and passed, the student is prepared to take specific certification classes and exams in whatever area of HVAC they choose to explore.

Exam and Experience Needed for Certification

No prior experience is required to start an HVAC training program past the desire to learn how to install, troubleshoot, and repair the equipment. Some two-year schools might require potential students to take the ACT or SAT exams or complete a skills assessment for English and math placement.

HVAC Degree & Certification Options

Here are the main types of HVAC Training programs:

  • Certificate in Heating Venting and Air Conditioning
    This program takes between six months and a year to complete. During the program, students will learn about HVAC system and design, residential and light commercial systems, electrical systems, and refrigeration systems. At the end of the program, students will be ready to start an entry level position in the HVAC industry.
  • Associate of Applied Science in Heating Venting and Air Conditioning
    This is a two-year program that covers everything the certificate program covers, but in more depth and with additional focus on physics, metal fabrication, heat pumps, and electrical system design. Graduates will be ready to work as a HVAC tech and do a variety of jobs from fabrications to installations and repairs.

Certificate of HVAC Cost

The price of these certificates varies by institution, but tuition, books, and fees for a certificate program at one technical college was $6,300 for in-state students and $7,500 for out-of-state students. The two-year program will cost roughly double that amount, so $12,600 for in-state students and $15,000 for out-of-state students.

Potential Careers & Salaries for HVAC Graduates

An HVAC technician with an associate degree might enjoy increased pay because the extra year of school provided education in areas that the certificate program does not address. That said, the biggest determiner for pay in this field is experience.

HVAC Tech Median Salaries by Occupation

Annual Median Salary by Occupation
