Mainstream engineering corporation Reviews

It is a great company and they have great products and they are known nation wide I have every license that they carry.

I have taken all of the online courses and tests that Mainstream gives (except for the EPA 608 which for the Universal level has to be proctored). This was out of both interest and because I teach college level environmental science. I found them to be very informative on the topics presented, well organized, and clearly written. In short, they did a good job with them and I learned a lot. It is a pleasure to recommend these courses.

Called with some issues with my certs. And low and behold the lovely lady was able to find my account my certs and they arrived in the mail a week later! Couldn t be happier

I took the Universal HVAC tech test 18 years ago and MEC is still in business, since then I have taken the MVAC and the company is still very professional and more importantly nationally accepted.

What a great place for truckers to deliver loads. Unloaded in no time, the forklift driver NATHAN is the nicest persons ever.

Keep it up guys!

Good and fair price, while covering the essentials during the exam.

The HVAC certifications offered here are immensely industry standard and current. You get all your certifications in one spot so you can always reference back to them if you need to reprint or order more you can get hard cards as well as certificates this is a phenomenal resource for an HVAC professional. Also, their customer service is by far one of the best.

This is where I was able to get my first Certification that lead me to be where I am today in the Industry.
I didn't pass the first time, but after my phone call to Mainstream about my test and the results, an agent was able to see & correct some mistakes that had been made on the scoring, at that time, and then allow me to get my certification. The Mainstream Engineering downloadable test program REALLY helped me a lot with my test. With an almost exact test-like experience on my laptop, I was able to be prepared for the real test.

The EPA course was well thought out with technical definitions and information flow cohesive and understandible.

Great people, I was a contractor for them. Very clean and well organized.
