Student Testimonials

In 2014, I  migrated to the United States (Delaware). I developed an interest in HVAC, so I started researching institutions that provided the necessary training. I discovered the Delaware Skills Center, that gives free training.

After twelve weeks of classroom and practical training, I graduated with a level one Certification. Through DSC I interviewed with numerous companies and I got employed with an Commercial HVAC company. Now I  am an Journeyman's mechanic working for the same company. The Delaware Skills Center gives me the necessary training    to get me to this point.

For a 12 week, 5 day a week (almost 400 hrs) course, we learned the basics of basically everything HVAC. I was      lucky to have Mr. Schneider as an Instructor. I say lucky because he also possess  like a thousand yrs as a Master Electrician, and was able to enlighten us with a lot of electrical info that we probably wouldn’t get to until about     our 2nd or 3rd year of HVAC training, much appreciated!
This program helped me land a job at Moon Air, where I’m an installer (apprentice).  I basically got hired on the     spot, in which, I believe that my interviewer was shocked how much I learned in that 12 week period and also obtaining my EPA universal, while there, was the icing on the cake.

Delaware skills center is a life changing school.   If you’re looking for a school that offers free tuition, free books, tools and equipment to use and learn with, then Delaware Skills center is the school you’ve been looking for. They will even ensure that your resume is updated, corrected and geared towards the trade you’re studying. After graduating I had two job offers! Which would not be possible without the Skills Center. There really is no good reason to not apply.

In 2019, I went to college and graduated with an associate's degree. I obtained a job in my degree field but unfortunately was let go due to COVID. So I decided to go back to school and choose Delaware Skills Center, HVAC program for my future career.

In 12 weeks, Monday through Friday classes, I was able to gain the knowledge needed to succeed in the HVAC field through class instruction and working in the shop with the help of Mr. Schneider. Since graduating I have been hired and started working as an HVAC installer. This wouldn’t have been possible without the HVAC program here at the Delaware Skills Center.
