We have used Haley Mechanical for a while now, and we have never been dissatisfied with any of their work. I like the fact that they send the same person out each time, because I do not want a parade of strangers traipsing in and out of my home. I quit using my last heating and air company for that very reason, and then lying about it. I saw the Haley Mechanical truck at my neighbor's home, and I asked her about them. She said they were a great company. She was right! The last time they were here, it was to fix an igniter on the hot water tank. I was bathing my little dog in the sink next to it, and I accidentally splashed water on it and I guess it shorted out. Anyway, they fixed it for me, and they did a great job! The tech is a very nice person, and very professional. I plan to keep on using them!
