I have used Haley Mechanical for years, and they are a great company! They treat you like a human being, and not just like a customer. They are very personable, and they really care about you. For example, one time they came out for the routine maintenance visit, and found that a part had to be replaced. They got the part and came back out a few days later to put it on. But, they only charged for the part, and not the second service call, since they had just been out a few days earlier. It is things like that which makes me continue to use them! They treat you fairly! They are just good people!
