My name is Chad and have been in the trade for 10 yrs. after high school started working for York at the factory.Then they moved the plant to Mexico and I thought hey I know a little about A/C's so i went to trade school and said well I guess i don't know as much as I thought. Then after trade school went to work and after some refrigeration calls I really said WoW I have alot to learn . And i am still learning. Thats why I am here.
