A1 Heating installed a new furnace for me. They were very prompt. My furnace had stopped working and they were here within an hour of when I called. They got it running again, but we knew it was short lived. They didn't charge for that visit, but scheduled the installation of the new furnace for a few days later. The installation went very well. They had some questions about where to put the venting and that sort of thing. When they were done, the inspector came and said it was all good. It's a very nice furnace. I thought the price was very good. I hadn't used their service before, but I would go back. They'r really reliable, efficient, and competent. They knew what they were doing and they did a good job.
