A1 Heating St. Albert Ltd. has been such a great company to do business with. I have used them about three or four times now and plan on continuing to use them. I recently had them come out to do some routine maintenance on my air conditioning unit. I think they added some freon and got it up and working properly. I am a very satisfied customer. The technicians are always very knowledgeable and courteous. A1 Heating St. Albert Ltd. happens to be a local business. Of course, I try to support local companies when I can and this is one of them that I highly recommend. Their prices seem to be competitive too.
