HVAC Technician at work

The Technical Training Institute is in our 15th year as a board-approved provider of the most comprehensive contractor Professional Development and License Exam Prep courses in North Carolina; teaching our students the latest industry and license exam information.


Exam Prep Courses: We take the anxiety out of the licensing an testing process. Our course covers hundreds of sample test questions in two fast-paced days for NC electrical, plumbing and heating applicants. Over 90% of TTI students learn to use the code books and apply simple techniques to pass their license exams the first time. 


NATE Technician Certification:  One-day certification courses to build the knowledgeable,

well-trained and highly experienced technicians sought by employers, contractors and consumers.


Professional Development:  Engaging, multi-media presentations teach real-world skills our students use the very next day in the field.


Design Services: TTI now offers load estimating and hvac system services. Our mechanical design staff starts with a detailed plan analysis and provides complete room by room loads based on your specifications. This program also offers technical assistance, design reviews, and field consultation services. Technical excellence, responsive scheduling, and fast, efficient results are just a few of the benefits of TTI's design service.


Research and Development:  In 2012, a collaborative effort between contractors and

leading chemists resulted in a  polymeric sealant that cures "Dirty-Sock Syndrome", the

coil-odor problem that has plagued the hvac industry for decades. 


VindEX Ultra is the only field-applied cure for "dirty-sock" syndrome, that locker-room

smell that affects aluminum coils.  With a 100% success rate; professional application

takes minutes instead of weeks,  greatly reducing the downtime required to seal the coil

and eliminate all odors.  Did we mention it's cost efficient? Less than $70 to seal and protect

a residential system, for  more  information, visit  www.vindexultra.com or visit your local supply house.
