Barrus Heating And Air had to come out and fix a refrigerant link. I've used Barrus for years. Bill is a brilliant engineer and he really knows his stuff well. I've been very satisfied with them. It was James who came out to fix the refrigerant leak. James is the nicest guy to work with, and he also knows his stuff really well. I have been very satisfied with my experience with Barrus Heating And Air.
