I have been using One Hour Air Conditioning & Heating for about three or four years now, and let me tell you, they are excellent! Their employees are always clean, polite, and courteous. They do very professional work, and I have no qualms at all about recommending them to anybody who needs air conditioning or heating services. Their employees are just super nice individuals, and they are so quick to show up. I mean like Johnny-on-the-spot quick! I give One Hour Air Conditioning & Heating Five Stars in every category!
