New to the industry and newer to the Forum. I have over 25 years in the Sheet metal trade and was looking to transition into something a little less physical and a little more challenging. After a crash course overview of the hvacr trade I tested for my EPA certs and was then promptly thrown in the deep end of the pool. It has been alot more physical than I had thought,and Way more challenging! The physical end of it may be from lack of practical experience, and the realization that the equipment is not always in the most convienent places to work on them. It has definetly been an eye opener.
