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.
Had our unit replaced with them a few years back after repair. Our ac stopped working right two days ago, and it was hotter inside then out. We out in for a service request and we’re back up with cool air before 11 am on Monday :) always professional, always kind, and a great price!
This company is so amazing and there technicians and installation and installers are amazing. I highly recommend this company to anyone. Thank you to everyone for helping us someday to get a new heater installed and take the old one out. Cleaned up and did ?? PERCENT perfect jib. Thank you so much for your hospitality and great service
Our AC seemed to have quit on us shortly before a very hot weekend and no one could get us in. A-1 got someone here the same day. Scott did an EXCELLENT job. Not only did he find and fix the issue, he also helped hook up a thermostat that we’ve been wanting to change out for a very long time. He did great work and was very communicative, explained everything as he was doing it, I can’t recommend him or this company enough. Thank you Scott and A-1!
These guys were great, they cleaned our pellet stove and chimney even with snow on the roof and then a few days later my blow fuse went out and they came back the next day and replaced that too.The workers are very knowledgeable, polite and nice. They took their shoes off every time before coming into our house and answered all of our questions.We heard about their business through a friend who also highly recommended them.
