Overall satisfied. They were very accommodating because I missed their call and they fit me in their schedule later the same day. Very friendly and knowledgeable. This is the second time I have used them and would use them again. The only thing was, I didn't know how to change the filter or the size, so I had to do all that myself after he left and it was really difficult for me with my furnace. Now I'm stocked up and ready for next time.
