Is Refrigeration the Same as HVAC?

Although many people think that refrigeration and HVAC are the same things, this is not the case. There are quite a few differences between these two fields of employment.

HVAC and Refrigeration – The Main Differences

Technicians in the HVAC field will usually focus on central heating and cooling systems that are used to improve quality or provide a comfortable air temperature for occupants in a building. While refrigerants typically are also used to lower the air temperature inside buildings, they are used more often to control the temperature in more confined areas such as residential and commercial refrigerators and freezer units. 

Although HVAC technicians and refrigeration technicians will often use many of the same tools, their overall scope of work will be a little different from each other. 

Comparing Tools Used for HVAC and Refrigeration

While tools such as ratchets, screwdrivers, and wrenches will be used by refrigeration and HVAC technicians, other devices will vary between the two:

Commonly Used Tools and Equipment by HVAC Technicians

These can include, but may not be limited to:

  • Manifold hoses
  • Gauge manifolds
  • Temperature gauges
  • Air velocity measurement instruments
  • Oxygen indicators
  • Carbon monoxide indicators
  • Carbon dioxide indicators
  • Vacuum pumps
  • A wide range of tools will be used for bending, cutting, and crimping various types of piping used to install, repair, and maintain HVAC system components

Tools and Equipment Commonly Used by Refrigeration Technicians

Some of the most common tools and pieces of equipment used by Refrigeration Technicians will include:

  • Thermometers
  • Multimeters
  • Refrigerant leak detector units 
  • Refrigerant recovery units
  • Refrigerant recovery tanks
  • Manifolds
  • Gauges
  • Welding torch kits
  • Vacuum pumps
  • Valve core removers
  • Service valve wrenches

Comparing Working Environments between HVAC Technicians and Refrigeration Technicians

HVAC technicians will be responsible for installing, servicing, and repairing systems that comprise a complex setup of filters and ductwork. These systems work to keep air circulating while keeping its temperature constant. As a result, HVAC systems can run hot or cold, keeping building occupants comfortable. 

In most cases, air conditioning units are situated outside a building, while their required furnaces and connecting ductwork are typically installed inside. Because these systems often require servicing and repairs and are located outdoors, HVAC technicians may often have to perform their duties in uncomfortable or cold working conditions outside. 

Technicians who choose to specialize in refrigeration, you’ll work with self-contained units that are designed to cool a particular area, such as a freezer, refrigerator, or large cold storage area. Although there isn’t a lot of ductwork to worry about with these installations, it is replaced by a plethora of tubes and coils that have to be correctly maintained to ensure maximum cooling efficiency. 

Refrigeration units are available in several sizes, models, and types and are mainly used indoors. While this may make working conditions a little more pleasant weather-wise, it can sometimes be inconvenient when a refrigeration technician has to perform their duties in a severely limited space. 

One of the main aspects that HVAC technicians and refrigeration technicians will have in common is that they will often be required to work over weekends and during holidays to perform repairs. 

Is it Hard to be a Refrigeration Technician?

One of the most important things to keep in mind when deciding to become a refrigeration technician is that you will have to be willing to perform a lot of hard physical labor. Therefore, if you are looking for a career path that keeps you physically busy, this will be an excellent choice. 

If you’re not keen on performing physical labor and you’d prefer to work at a job that involves being in an air-conditioned office for most of the day, this will not be the right line of work for you to pursue. In addition, if you’re only keen to log 9 to 5 workdays and be off over weekends and holidays, this job will not be a suitable fit for you.

Does Refrigeration Pay Well?

The average starting salary for a refrigeration technician in the U.S. runs at around $24 per hour, with more experienced and knowledgeable candidates earning as much as $45 per hour in some cases. This means that many of these technicians can earn salaries of as much as $56,000 to $65,000 per year – without taking any overtime or holiday pay into account. 

Once fully qualified and extensively experienced, a reputable refrigeration technician may be able to command a salary of over $70,000 per year – especially if they decide to start their own business. 

The pay rate for a refrigeration technician will also depend on which part of the country they decide to work in because some areas offer better hourly rates than others. For example, Alaska offers some of the highest hourly rates for refrigeration technicians at the moment, while Mississippi offers some of the lowest known rates for performing the same tasks. 

Along with above-average hourly rates of pay, many refrigeration technicians have reported that the companies hiring them offered a range of other benefits as well, such as:

  • Discounts for fuel
  • Prescription drug insurance
  • Partial or even full reimbursement for cellphone bills
  • Paid time off
  • 401(k) as well as matching contributions
  • AD&D insurance
  • Dental insurance
  • Disability cover
  • Health insurance
  • Life Insurance 
  • Vision Insurance

When considering which career path to follow, another essential aspect to consider is the job outlook over the next few years. Will the number of job vacancies increase or decrease for that specific field?

The current job outlook for refrigeration technicians is excellent. Job growth rates are expected to reach more than 34% year upon year between now and 2026, making this career path a superb choice if you’re keen on job stability. 

Refrigeration technicians who are willing to learn and continually update their qualifications and knowledge will find that they will be able to enjoy highly successful and financially lucrative careers for several years to come. 

How Can I Become a Refrigeration Technician?

Although not every refrigeration technician will have to follow the same path to becoming accredited, the information in the steps below will provide a basic idea of what will be required before you’ll be allowed to work in this field.

1. Obtain your High School Diploma or Obtain a GED

Although there are no specific educational requirements for becoming a refrigeration technician, most people working in this field will at least have some form of post-secondary training or a degree – and you will need to have your high school diploma or GED before being able to study towards these. 

If you intend to follow this career path, you must ensure that you obtain excellent results in mathematics and science. You may also want to enroll in a recognized vocational refrigeration technician-training course. 

2. Enroll in a Recognized Certificate or Degree Program (Six Months to Two Years)

After finishing high school, many prospective refrigeration technicians decide to enroll in a post-secondary training program to either earn an associate degree (two years of study) or a recognized certificate (six months to two years of training). 

One example of a course that can be enrolled in is that which is offered by Gadsden State Community College in Alabama, namely a two-year associate of applied science degree in air conditioning and refrigeration. In addition, the institution also provides a short-term and regular certificate course in these fields. These programs will cover topics such as math, circuitry, and the fundamentals of refrigeration systems.

3. Serve an Apprenticeship (Two to Five Years)

Many refrigeration technicians get a start on their career paths by serving an apprenticeship – that is, working under a fully qualified, licensed, and experienced refrigeration technician until they have gained sufficient knowledge and experience to work unsupervised.

4. Complete the Required EPA Section 608 Certification

Every technician who intends to work with refrigerant products will be required to earn the EPA Section 608 Certification. Training for this will usually form part of the initial refrigeration training course. However, if it isn’t part of the course being studied, additional training will be needed to earn it. 

This particular certification has four different classifications that require four separate tests. A technician will need to earn those relevant to the types of equipment they will be installing, servicing, and repairing. The four classifications include:

  • Class I – Small Appliances
  • Class II – High-pressure Appliances
  • Class III – Low-pressure appliances
  • Universal – All kinds of refrigeration equipment are covered here

For any technicians who have started working without having been enrolled in a formalized program or where test prep was not included, the ACCA allows them to enroll in a three-hour online EPA Section 608 Certification Test Prep Course for a nominal fee. 

5. Apply for and Obtain the Relevant State or Local Licensure

These days, the vast majority of states will require refrigeration technicians to obtain some form of license before working in this field. Each state has its requirements, so inquiries will need to be made to the relevant authorities to determine what will be required.

The institutions mentioned below offer an extensive range of certifications for refrigeration technicians:

  • HVAC Excellence offers a highly progressive system of accreditation that will enable technicians to demonstrate that they are more than just ‘suitably competent to perform the required tasks
  • North American Technician Excellence (NATE) offers a range of generalized refrigeration certifications for technicians and contractors. Four different certificates are provided for these technicians during the various stages of the first five years of their working in this field – natex.org
  • National Inspection Testing Certification (NITC) offers various specialized certifications for the more experienced refrigeration technicians in STAR HVAC/R mastery and different HVAC/R brazing processes – nationalitc.com
  • The Refrigeration Service Engineers Society (RSES) provides a range of general refrigeration certifications, along with others to demonstrate that a technician has specialized skills such as R-410A, HVAC/R electrical and commercial refrigeration – reses.org

6. Be Willing to Pursue Advanced Certifications

Many more professional prospects will often be available for refrigeration technicians who are willing to obtain certifications over and above the minimum ones required to work in this field. 

Having one or more advanced certifications or qualifications will usually result in additional increases in salary in a current role. Having other qualifications on your resume will also demonstrate to prospective employers that a technician is willing to go the extra mile about learning as much as possible about the job. 

Basic plumbing and electrical skills may sometimes be required when working as a refrigeration technician. 

Obtained your Required Certifications, and are you Searching for a Job as a Refrigeration Technician?

Suppose you’ve recently obtained the required certifications to become a refrigeration technician, but you don’t have any work experience. In that case, you may be finding it challenging to secure a position. However, there are a few hints and tips that will help ensure that your resume and application paperwork stand out as much as possible to prospective employers:

  • Proofread your resume before sending it off. Please have at least two people thoroughly read your resume before sending it off to apply for a position. This will help catch any spelling or grammatical errors beforehand – many recruiters will toss resumes aside that are littered with mistakes.
  • Only apply for positions that match the certifications you have. Seriously. Attempting to use for a place that you are not suitably qualified for could result in you having to demonstrate skills during a practical test that you may not be familiar with – if this occurs, many companies will go as far as blocking your resume to prevent you from applying with them again.
  • Always reply promptly to emails, messages, or phone calls from prospective employers. In most cases, you need the job more than the company needs you explicitly to fill the position, and candidates who are slow to reply – or worse, don’t reply at all – will be eliminated from the pool of applicants.
  • If you’re fortunate enough to be contacted for an interview, ensure that you dress appropriately and arrive a few minutes early. Candidates who arrive late will usually be set aside in favor of prompt ones.
  • Turn your phone off during the interview. There is little else as annoying and rude as someone who constantly checks their phone while they’re being interviewed to fill a vacancy. This could also indicate to prospective employers that you’ll not pay as much attention to your job as you should
  • After your interview, be sure to thank the interviewer for taking the time to meet with you and let them know that you look forward to hearing from them as soon as they’re ready.

Keeping the tips mentioned above in mind when being contacted to interview for a vacancy as a refrigeration technician will help ensure that you leave a lasting memory for interviewers, HR employees, and managers – one that is positive.
