Do you need to build a Certified HVAC technical team quickly?

What if you could hire based on personality and mechanical aptitude? Add reasonably priced NATE HVAC training with a short-term return, and the job performance stands a good chance of quickly excelling.

What if you can allow someone to succeed in a trade that they would not ordinarily consider? We all remember the company that gave us our first shot!

What if you can build job-ready HVAC technical teams in the short-term instead of the scientists that so many training companies envision that takes years?


Do you want to train, certify and prove your worth to employers and customers?

Training systems have advanced. Content has been modernized. Specialty training companies deliver training that helps you to build knowledge to get in the door and advance. Existing technicians benefit from training that delivers fast results on your schedule.

Qualified candidates that have completed the “book work” and are otherwise employable usually enjoy much higher employment rates than those who start from scratch.

I am (brand) new to the industry. Which training should I take first?

Start with the Ready to Work exam. It is the simplest, can be taken online without a proctor and is the least expensive.

I have less than 6 months experience. Which course is recommended?

This is a good question. If you have never had any formal training in the HVAC field then we recommend that you start with the basics and work up.


Ready to Work – the most basic, intended for anyone on the HVAC field to begin their understanding of the equipment.

 Support Technician or Certified HVAC Professional – Either of these two courses are a great ‘next step’. Both require about the same study time although the NATE fees for the Support Technician exam is probably lower.

I want to start on training. How long will the training take?

Our courses are designed to be completed at your own pace, so there is no set time frame for completing the training. However, we recommend dedicating a sufficient amount of time and effort to fully prepare for the NATE Exam, as you may need additional time to master some of the concepts.

Which of the NATE courses sold here require a proctor?

All EXCEPT the Ready to Work.

Proctors can be booked online for a fee to administer the proctored exam.

Many supply houses employ a proctor that could proctor your exam in person; possibly for a fee.

Trade schools often offer NATE proctoring sessions; for a fee.

The natural order of your courses!

We are often asked about which order of courses someone new to the industry should pursue. Here are our recommendations.

Ready to Work – the most basic, intended for anyone on the HVAC field to begin their understanding of the equipment.

 Support Technician or Certified HVAC Professional – Either of these two courses are a great ‘next step’. Both require about the same study time although the NATE fees for the Support Technician exam is probably lower.

I've noticed NATE courses costing close to $3,000

The eTech Training Center is able to provide the entirety of their Certified HVAC Professional program for under $101 because they are committed to providing high-quality, affordable training solutions.

Unless the program is financially accessable students suffer.

ETech’s instructors are highly experienced and certified in many areas, such as HVAC, air conditioning, and refrigeration. They also utilize a self-paced online learning platform that allows learners to complete the entire course whenever it works best for them. This makes it more economical than traditional classroom-style learning and eliminates the cost of travel or extra time away from work.

Besides, what happens if you hate your career after spending or borrowing $3,000++? Not everyone will continue after training choosing instead a different field or career options.
