HVAC Certification
Is HVAC Certification Worth The Money?
A lot of people who are new to the HVAC industry are curious as to whether or not it is even worth it to become HVAC certified.
This is an absolutely valid question. I mean, let’s be real, exam prep materials are not cheap and people don’t want to spend their time studying for a certification that isn’t going to give them some sort of return. So is it worth it?
My Take: Certifications Can’t Hurt
There are a lot of different situations and circumstances that could play into this decision, so only you can decide whether or not certification is something you want to pursue. However, I am always of the opinion that if you have the opportunity to get a certification, it can’t hurt.
The HVAC industry is competitive, and there are lots of qualified candidates out there and personally, I want every advantage I can get. Whether its for a position I am applying for, or a position within another company, the certifications will always be helpful.
Companies Like HVAC Certified Employees
Just like you find yourself competing for a job, HVAC companies compete everyday for customers.
And just like you, they want to be able to tout as many accolades as they can. This is why many companies are willing to pay for their employees to become certified – because they want to be able that all of their technicians are certified in one way or another.
This is why if you are applying for one o these types of companies, you are immediately more desirable. They don’t need to invest more money into you because you have already put in the work and time needed to obtain certification.

HVAC Certification Online
A lot of people want to know if it is possible to get an HVAC certification online. There are a number of online schools that offer HVAC certification programs that prepare you to take any number of the HVAC certification exams.
There are many benefits to taking an online HVAC certification course. First, you are able to complete your classes from home without ever having to travel to a physical location. Also, many times, you have the freedom to complete coursework at your own pace. Assignments are typically handed out weekly and due the following week. This gives you the option of working on your assignments at your leisure, and at a time that is convenient for you. Many people who have full time jobs prefer this as it gives them the option of working while still completing the required schooling. Furthermore, many online classes are cheaper than going to an actual college or university. The certificate you receive after passing is generally comparable to that of an actual college.
Although there are many benefits to completing your HVAC certification online, there are a few challenges as well. The biggest hurdle that online students face is being able to handle the flexible schedule. A lot of people struggle with being able to motivate themselves to complete the required coursework. You must be able to plan your time wisely and avoid procrastination. Furthermore, you will lack the direct one on one interactions that are often available in typical colleges. Many online courses offer some sort of interaction between students and facilitators, although it is typically not as often nor in depth as it would be elsewhere. If you are the type of person who needs guidance from an instructor, this may be a challenge for you.
Once you have completed your online coursework, you will likely have the knowledge to take one of the recommended HVAC certification exams. Some exams require on the job knowledge. This hands on experience is often gained through apprenticeship with an HVAC company. Completing an HVAC certificate program online will show potential employers that you are serious about your career and likely make it easier for you to find apprenticeship.
You are probably still unsure about whether or not HVAC certification online programs are for you. It is best to research a few online courses to see if their program suits your needs. Many companies allow you to try out, or see a demo, of what the “classroom” environment would look like so you can be sure you are comfortable within the online environment.
Do You Need to Go to School to Obtain HVAC Certification
A lot of people wonder if there are any education requirements before they can obtain their HVAC certification. Typically, there are no formal requirements in order to become certified. However, it is considered quite beneficial to have some sort of higher education related to HVAC systems.
HVAC Certification Classes
Many universities and community colleges offer several courses related to HVAC. Whether those courses are about heating, refrigeration, electrical, or air conditioning, the added knowledge will be beneficial. Also, there are some HVAC courses that are offered online so that you can take classes from the comfort of your own home. It is recommended that you speak with your possible employer before enrolling in any classes.
If you would prefer not to pursue formal classes, you can get on the job HVAC training through an apprenticeship. Many companies offer apprenticeships to persons who are pursuing an HVAC career. You would be partnered with an experienced HVAC journeyman and work side by side with them so that you can learn the trade.
Landing an apprenticeship often times leads to employment with the same company as a full fledged HVAC journeyperson. The company has invested time and money into your training and as such, will likely want to keep you on to utilize your skills. However, if for some reason they choose not to, having an apprenticeship on your resume will likely improve your chances of landing a job with another company.
There are many options available to obtain your HVAC certification. There is no one size fits all method that works for everybody. The best advice is to find an employer that you would like to work for, and ask them for advice on what they consider to be best. Also, if you are looking for advice, you can ask another HVAC technician for tips on the best actions to take.
In conclusion, no, you do not need to go to school to get your HVAC certification. However, there are some benefits to obtaining a higher education related to HVAC as mentioned above.

EPA 608 Certification
The EPA 608 certification is the first HVAC certification you should pursue. Why? Because it is a federally mandated certification! That means that if you are going to be buying or working with refrigerants, you are going to need to pass this test first.
Types of EPA 608 Certification
As discussed in our What is EPA Certification? post, there are 3 types of EPA 608 certification available. They are:
- Type I – Small Appliances
- Type II – High-Pressure
- Type III – Low Pressure
There is a specific exam associated with each of the separate types of certifications. In addition, you will need to pass a CORE exam that is required for all certifications.
The CORE EPA 608 certification exam covers a wide variety of HVAC topics – it is the least “focused” exam, if you will. The exams relating to the Type I, Type II, and Type II certifications are much more centered around their applicable topic, and rightfully so. According the EPA, the CORE exam consists of the following topics:
CORE
Ozone Depletion
- Destruction of ozone by chlorine
- Presence of chlorine in CFC and HCFC refrigerants
- Identification of CFC, HCFC, and HFC refrigerants (not chemical formulas, but idea that R-12 is a CFC, R-22 is an HCFC, R-134 is an HFC, etc.)
- Idea that CFCs have higher ozone-depletion potential (ODP) than HCFCs, which in turn have higher ODP than HFCs
- Health and environmental effects of ozone depletion
- Evidence of ozone depletion and role of CFCs and HCFCs
Clean Air Act and Montreal Protocol
- CFC phaseout date
- Venting prohibition at servicing
- Venting prohibition at disposal
- Venting prohibition on substitute refrigerants in November, 1995
- Maximum penalty under CAA
- Montreal Protocol (international agreement to phase out production of ozone-depleting substances)
Section 608 Regulations
- Definition/identification of high and low-pressure refrigerants
- Definition of system-dependent vs. self-contained recovery/recycling equipment
- Identification of equipment covered by the rule (all air-conditioning and refrigeration equipment containing CFCs or HCFCs except motor vehicle air conditioners)
- Need for third-party certification of recycling and recovery equipment manufactured after November 15, 1993
- Standard for reclaimed refrigerant (ARI 700)
Substitute Refrigerants and oils
- Absence of “drop-in” replacements
- Incompatibility of substitute refrigerants with many lubricants used with CFC and HCFC refrigerants and incompatibility of CFC and HCFC refrigerants with many new lubricants (includes identification of lubricants for given refrigerants, such as esters with 134; alkylbenzenes for HCFCs)
- Fractionation problem–tendency of different components of blends to leak at different rates
Refrigeration
- Refrigerant states (vapor vs. liquid) and pressures at different points of refrigeration cycle; how/when cooling occurs
- Refrigeration gauges (color codes, ranges of different types, proper use)
Three R’s
- Definitions
- Recover
- Recycle
- Reclaim
Recovery Techniques
- Need to avoid mixing refrigerants
- Factors affecting speed of recovery (ambient temperature, size of recycling or recovery equipment, hose length and diameter, etc.)
Dehydration Evacuation
- Need to evacuate system to eliminate air and moisture at the end of service
Safety
- Risks of exposure to refrigerant (e.g., oxygen deprivation, cardiac effects, frost bite, long-term hazards)
- Personal protective equipment (gloves, goggles, self-contained breathing apparatus–SCBA–in extreme cases, etc)
- Reusable (or “recovery”) cylinders vs. disposable cylinders (ensure former DOT approved, know former’s yellow and gray color code, never refill latter)
- Risks of filling cylinders more than 80 percent full
- Use of nitrogen rather than oxygen or compressed air for leak detection
- Use of pressure regulator and relief valve with nitrogen
Shipping
- Labels required for refrigerant cylinders (refrigerant identification, DOT classification tag)

NATE Certification
NATE certification (North American Technician Excellence) is widely considered to the be the gold standard of excellence in HVAC training and certification. Consumer Reports has recently started recommending that any HVAC work you are having done be completed by a NATE certified contractor.
NATE certification does not have any eligibility requirements – no previous work experience or training needed. All you have to do is register for, and pass the exam. After passing, you will receive a NATE ID card to show to prospective employers and/or clients to prove that you are NATE certified.
NATE certification exams consist of a core exam and a specialty exam. You are offered the choice of a focus of either installation or service. There are a total of 21 specialty exams for you to choose from. Each of the specialties listed below are offered with the focus of installation or service.
- Air Conditioning
- Air Distribution
- Air-to-Air Heat Pumps
- Gas Furnaces
- Oil Furnaces
- Hydronics Gas
- Hydronics Oil
- Light Commercial Refrigeratioin
- Commercial Refrigeration
- Ground Source Heat Pump Loop Installer
- HVAC Efficiency Analyst (This exam is a Senior Level exam – there is no specific focus attached)
As an example, you could choose to take the Core installation exam, along with the Air Distribution installation exam to become certified. You could also choose to take the Core service exam, along with the Air Conditioning service exam to become certified.
NATE does not administer the exams themselves so you will need to locate a testing location near you. Testing locations can be found on the NATE website. You must pass both the core and specialty exams in order to become certified. If you pass one exam and fail the other, you will have 2 years to pass the other exam. If 2 years have elapsed since you passed the first exam, you will need to retake both exams. Once you have passed, your NATE certification will be good for 5 years. You may retake the tests prior to the 5 year mark to regain certification for an additional 5 years.
NATE certification exam fees vary so please check with your local testing location for fee information.
Have you already received your EPA Certification? If not, check out our article explaining what you need to know to become EPA Certified.
EPA Certification Explained
EPA Certification
The Environment Protection Agency (EPA) has a certification program that is required by federal law in order to be able to handle or work with refrigerants called EPA certification. This is often the first certification that HVAC professionals pursue being that it is required by law. There are two different types of EPA certification:
EPA 608 Certification
The first, and most commonly pursued certificate is the EPA 608 Certification. There are 4 different types of certification depending on the type of work you will be conducting:
- Type I – Can only work on small appliances containing 5 lbs or less of refrigerant
- Type II – Can only work on medium, high, and very high pressure appliances
- Type III – Can only work on low pressure appliances
- Universal Certification – Someone who possesses Type I, Type II, and Type III certifications.
All of the certification tests also require you to pass a CORE exam. Any of the tests listed above may be taken one at a time, or all together at once in conjunction with the CORE exam.
The EPA 608 Certification is currently the only nationally mandated requirement. However, many states, or even some counties, have their own requirements in addition to the 608. Very few require additional certification (some do!) but many offer a state mandated exam in order to legally work with HVAC systems.
EPA 609 Certification
The EPA 609 Certification is specifically for those persons looking to work on motor vehicle air conditioning systems.
This certification allows the purchase of any refrigerant in any size from an auto supply house for use in the cooling of passenger compartments in motor vehicles. This certification is much less common and is pursued mainly by auto mechanics working with MVAC units. The exam is similar to those listed above. If you have no intention of working with MVAC units, this certification will most likely not be relevant for you.
