A few fast facts to set the stage

• HVAC technicians earn a median salary around 50,590 dollars in the United States, and demand is rising (see our HVAC industry news).

• The field is projected to add more than 38,500 jobs by 2030.

• Trade school HVAC programs typically run 6 to 24 months and lead to a certificate or an associate degree.

• Apprenticeships usually last 3 to 5 years and follow an earn while you learn model.

• EPA Section 608 Certification is mandatory for anyone who handles refrigerant, and the Universal exam has 100 questions with a 70 percent passing score.

• Section 608 certifications do not expire once earned.

Step 1, meet the education baseline, high school diploma or GED

If you are mapping how to become an hvac technician the starting line is clear. Most employers and training programs expect a high school diploma or a GED. Programs and apprenticeships use it as a screening tool because HVAC work requires reading wiring diagrams, doing load calculations, and understanding safety instructions. If you are still in school, classes in vocational tech, shop, algebra, and physics give you a head start.

Step 2, pick your training path

There is more than one way to figure out how to become an hvac technician. Choose the lane that fits your budget and timeline.

HVAC training program, certificate or associate degree

Technical schools and community colleges offer structured HVAC programs focused on theory and hands on skills. Typical timeline is 6 to 24 months. Shorter programs usually award a certificate, and two year tracks can grant an associate degree. Expect labs on refrigeration cycles, electrical controls, brazing, airflow, and troubleshooting. Many employers prefer applicants who completed a one year certificate or a two year degree.

Apprenticeship or on the job training

Apprenticeships combine paid work with classroom learning. Most run 3 to 5 years. You begin with tasks like insulating lines or cleaning burners and progress to soldering, wiring controls, and full system diagnostics under a journeyman’s supervision. Apprentices typically start around half of a technician wage, about 12 to 15 dollars an hour with periodic raises as skills improve. It takes longer than school, but you earn money the whole time and avoid tuition.

Tip, you can also blend the two paths. Many apprentices take evening or online classes to speed up classroom requirements and certification prep.

Step 3, get your mandatory EPA Section 608 Certification

If you handle refrigerants in any capacity you must hold EPA Section 608 Certification. It is required by federal law under the Clean Air Act. There are four types

• Type I, small appliances

• Type II, high pressure systems

• Type III, low pressure systems

• Universal, all of the above

Most new techs aim for Universal since it covers every category. The Universal exam is 100 multiple choice questions, Core plus Types I, II, and III, and you need at least 70 percent on each section. Good news, once you pass, your Section 608 certification never expires.

You can prepare and test online through an EPA approved provider. SkillCat is an EPA approved Section 608 certifying organization with remote proctoring, instant results, and certificate verification for employers. For a budget friendly route, sign up at SkillCat and schedule your exam when you are ready.

Cost note from a technician’s perspective, an online subscription option can be far cheaper than buying a 100 dollar study guide and paying about 60 dollars per local test attempt. SkillCat membership has been listed at about 10 dollars per month and includes exam access.

Step 4, understand state licensing requirements

How to become an hvac technician also depends on your state. Licensing rules vary. Some states license HVAC technicians at the state level. Others do not license techs statewide and leave requirements to cities or counties. Where a license is required, you usually need to document education or apprenticeship hours, hold EPA 608, and pass an exam on codes, system design, and safety. Contractor licenses have extra requirements like insurance or bonding. Always check your state and local rules before you start applying.

Step 5, add optional certifications that boost credibility

Optional certifications are not legally required, but they can improve employability and pay.

• NATE, North American Technician Excellence, is a nationally recognized credential. Techs pass a core exam plus a specialty like air conditioning or heat pumps and renew every five years with testing or continuing education. Studies show NATE certified techs have fewer callbacks and lower warranty costs. Employers often pay a premium and homeowners who know NATE prefer certified techs.

• R 410A safety training, R 410A runs at higher pressures than older refrigerants, so safe practices and proper tools are essential. The EPA does not require a separate R 410A license beyond Section 608, but many manufacturers request proof of R 410A training for equipment support.

• Manufacturer training, brands offer classes on their products including inverter systems and VRF. Certificates show you are current on brand specific procedures.

• Other useful add ons include HVAC Excellence, EPA Section 609 for automotive A C, and OSHA 10 safety cards.

SkillCat includes NATE aligned prep, R 410A safety training, and OSHA 10 access through a partner. Browse the training paths at SkillCat or dive into our advanced training for techs.

Cost of training and tools

You can build a plan that fits your budget.

• School tuition varies widely. Community colleges and online options tend to be more affordable than private trade schools.

• EPA 608 prep and testing can be very low cost with an online provider. A subscription around 10 dollars per month that includes exam attempts can be less expensive than a 100 dollar study guide plus 60 dollar test fees.

• Apprenticeships pay you during training, which offsets education costs.

• Tools are an incremental investment. Start with employer required basics such as hand tools, a multimeter, and a gauge set. Many shops provide specialty tools and you add gear over time.

• Safety and compliance courses like OSHA 10 are often inexpensive and are sometimes reimbursed by employers.
