The Schedule

Our program is designed so you can continue at your current job while preparing for your new career:

Classes run Monday through Thursday, with Fridays reserved as open days — ideal for catching-up on class work, or getting a few extra hours in our hands-on lab.
Morning Classes are 8 AM to noon, and evening classes are 6 PM to 10 PM.
The entire program is 26 weeks long — about six months.
New classes start every ten weeks.

The Results

Once you graduate, you'll have the skills and know-how needed to install, service, and repair both residential and commercial air conditioning, heating, and refrigeration systems. You'll be comfortable working with temperature control systems, air quality systems, and humidity and refrigeration — and you'll be qualified to work in both the private industry and major commercial companies (such as hospitals, hotels, office buildings, or manufacturers).

With your ATI training, you'll be able to work anywhere in the world.

Once you've successfully completed your ATI training, you'll be able to:

Troubleshoot and repair the mechanical and electrical components of residential and commercial equipment.
Replace residential and commercial condensing units, compressors, and evaporator fan motors.
Install and repair residential and commercial gas heating systems.
Maintain EPA regulations when troubleshooting and repairing residential and commercial equipment.
Service and repair ice machines, walk-in coolers and freezers, and reach-ins.
