I have used A1 Heating St. Albert Ltd. on a couple of occasions. First, they installed my air conditioning system for me, and then most recently, they installed a new furnace. I plan to have them come back out again and do some additional work for me in the near future. Their employees show up on time, and seem to be very competent people. They are very friendly, and courteous, and they do their job. To sum it up, A1 Heating St. Albert Ltd. is just a very solid and reliable company!
