First let me say that we shopped around (4 or 5 different companies) for price. I was just looking for an honest price with no pressure. Alpine (Mike) was suggested by a couple of friends. And I definitely made the right decision. The technicians were right on time and did an exception job. In and out in less than 7 hours! I can't say how pleased we are. Just wish we did this a long time ago. I will definitely recommend Alpine to all interested in any heating and cooling needs.
