We last used A1 Heating St. Albert Ltd. to install an air conditioning unit for us. We had used them before that, and had good experiences so when our unit went out, we asked them for an estimate, and then had them do the installation job for us. Their employees were friendly people, and they did an outstanding job for us on the installation. They were on time, and cleaned up well behind themselves. I was particularly impressed though, when the man who came out to give us the estimate, told us that our cold air return was in the wrong place. Three other companies had missed that. This problem was corrected during the installation, and it has definitely made a difference! Like I said before, impressive!
