I fall into that dreaded category of DIY. Mostly, I find myself on the receiving end of very poor service and want to learn more about diagnosing faults before calling the professional. As you all know U-toob is full of HVAC screw-ups and nightmares and I've experienced my share of them. I honor those who take the time to do it right, take pride in their work and get the job done. I just have to find out who you are!
Reality is that the HVAC business is locked up tight. I cannot get word one from an HVAC parts supplier, nor am I allowed to purchase parts from most sources. Sometimes this is a good thing for everyone's safety. Sometimes it is just downright silly. So, I will be interested in reading the info on the forum. Thanks for having me around.
