A Doubt That Turned Into an Opportunity

I’ve always been curious about manual work. I liked taking things apart to understand how they worked. But between paying the bills and taking a technical course, guess what got pushed aside? The dream, of course. Until a friend told me about a free residential electrician course in English — with certification.

At first, I was skeptical, right? But once I saw it was offered by Alison.com — with over 20 million students worldwide — I decided to give it a try. As a result, everything changed.

Where I Found Free Technical Training Courses

After taking one course, I was hooked. I started finding several international platforms offering 100% online and free courses, including certificates of completion. Here are the ones I liked and trusted the most:

How These Courses Changed My Life

I started with a basic electrician course. After finishing, I did a small project at home: installed new outlets and even replaced the circuit breaker. I gained confidence. When I posted about it on Instagram, two friends asked me to do the same in their homes. And yes: I charged them.

Later, I completed the HVAC course (Heating, Ventilation, and Air Conditioning), which is highly valued in the U.S. Today, even without a traditional diploma, I have international certifications and clients seeking me out.

Real Benefits of Learning a Trade Online

So, besides being free, here’s what you gain:

Total flexibility: study at your own pace, whenever you want
Internationally recognized certificates
No need to leave your house: it’s all online, on your phone or computer
Real savings: no transportation, materials, or tuition costs

Tips to Get the Most Out of These Courses

To help you avoid the mistakes I made early on, here are some golden tips:

Study in English, but use Google Translate if needed — you’ll get the hang of it over time.

Create a routine: even if it’s flexible, set specific days and times to study.

Take notes: especially about tools, regulations, and best practices.

Practice whenever possible: if it’s an electrical course, build a model setup. If it’s about mechanics, watch YouTube videos showing the process live.

In Summary, learning a trade online, for free, with certification and on your own schedule isn’t just possible — it’s a real opportunity to transform your life.
