Good evening to everyone. Just wanted to say that I am very excited to join the family and look forward to you Q and A's. I am very new to the HVAC/R although, I do have my certification for the last 2 years. I currently work in a multi-family community and have been for the last 10 years. I am responsible for servicing 150+ a/c. My education in this field is not formal, but rather, I've been thrown into the fire and have gained a lot experience and appreciation for all of you that have many years behind them. As I am finding out there is always a new challenge that I encountered and look forward to advice from you, the real professionals. Thank you once again for inviting me into the family.
