We had a lot of problems with A1 Heating St. Albert Ltd. and although the technicians were respectful and friendly I don't know that we would either use nor would we recommend them. They came out to look at our furnace over the winter but the problems with it got worse instead of better. They had to redirect the pipes. Where they redirected them the pipes froze over the winter so we had to call them back again and again. It is an older home and we knew we would have to replace or update things for regular maintenance and upkeep but to have to call the same company back over and over again has become very frustrating. I just don't know if we would use A1 Heating St. Albert Ltd. again.
