Glad you were taken care of.Most of us HVAC people just want to do a good job and have happy customers. I will say that I bet his next job with your equipment will go better for him. His techs are now also more able to handle more advanced systems which will give them the balls to sell up to better equipment. I am sure after all you went thru you will be happy. Could you please post a pic so we could look at the lines ect?
I hope you paid the man after what he went thru.
