The Problem

Sound Familiar?

A/C comebacks are frustrating because pressures alone don't always tell the whole story. Most technicians were never taught how to connect pressure, temperature, airflow, and control strategy into one diagnostic process. This class changes that.

Before This Class

Reading pressures but not knowing what they mean
Replacing parts and hoping it fixes the problem
Can't find the leak — system keeps losing charge
Confused by 1234yf and modern climate control
Comebacks that cost you time and credibility
Not sure if you're CCR 3366 compliant

After This Class

Understand what pressures and temperatures actually tell you
Follow a repeatable diagnostic process, not guesswork
Locate leaks systematically with confidence
Understand 1234yf and modern refrigerant systems
First-time fixes that stick — fewer comebacks
Covered under CA CCR 3366 requirements

The Method

Learn the MAT A/C Performance Logic Map

Oscar's Field-Proven Diagnostic Process

This isn't theory pulled from a textbook. The MAT A/C Performance Logic Map is the same process Oscar uses in the bay and has taught to technicians across the United States, Mexico City, and internationally at Automechanika. It connects every data point — pressure, temperature, saturation, airflow, and control strategy — into one clear decision path.

System Performance Evaluation

Understand what a healthy system looks like before diagnosing a sick one.

Pressure & Temperature Logic

Read and interpret high/low side data in context — not in isolation.

Saturation & Temperature Logic

Use saturation data to pinpoint exactly where the system is failing.

Leak Detection & Verification

Find leaks systematically — not by feel or luck.

Electronic Climate Control

Apply the logic map to modern automatic and dual-zone systems.

CCR 3366 & ASE A7 Application

Satisfy California compliance requirements and reinforce A7 exam knowledge.

What Technicians Are Saying

Real Results From Real Techs

★★★★★

"I live on the East Coast — most of my training has been between NY and Pennsylvania. I can say that making the long trip was absolutely worth it. The quality of the instructors is exceptional. The way Oscar interacts and takes the time to answer questions — even ones outside the topic — is an incentive to come back. Thank you for everything. God willing I'll be back in Rancho Cucamonga for another class at Master Automotive Training!"

★★★★★

"I've been following Oscar and MAT for a few months. His teaching style is genuinely understanding. His process and his passion — that's really not seen anymore. I believe his passion on the West Coast has sparked something across the country. This shop owner from Maryville, TN definitely enjoyed the hospitality and the training. I highly recommend MAT. You will not be disappointed."
