I had never used A1 Heating St. Albert Ltd. before this visit. I have a commercial building and was having difficulty with one of the air conditioning units and had called another company out who told me that I would need a complete replacement or have to replace a bunch of parts. Well I decided to get a second opinion and called A1 Heating St. Albert Ltd. They were terrific! They made some small repairs vs. replacement of the unit itself and replacement of a lot of other expensive parts. I think their honesty is outstanding! I would refer them in a heartbeat! I will use them again for my commercial properties and my personal home if I need them! I am very happy with their work!
