I have been using Precision Heating & Air for a while now and I am generally happy with the work that they do. Within the last year, I have bought 5 heating and air conditioning units from them. The technicians follow all the right procedures when doing the work. They are also very clean and thorough. I liked that the office team with very attentive when you call them and don't dismiss any concerns. I have no doubts that I would use them again in the future.
