“My husband and I called for a furnace that was not working. Eric came so quickly and thinking it was the circuit board but upon further checking found the heat exchanger was cracked so we would have needed to replace it. Since our furnace was 14 years old and we had trouble last winter we decided to replace the furnace. Eric and Aleck came and installed the new furnace and did such a great job seamlessly and efficiently. They were so helpful and friendly. Great Guys. I would recommend A-1 and Eric and Aleck very highly. They went out of their way for us above and beyond.“
