Recently my elderly mother returned from a trip to find her air conditioner was out of service. After contacting several companies and being told it would be anywhere from 2-3 days before anyone could help her, I  contacted Tucson A List and ultimately reached Jason Harris of Air Tropics. Jason arrived within an hour (yes, an hour) and assessed the problem and had it fixed in about a half hour for a very reasonable price. Thank you to Jason Harris of Air Tropics for his courteous and kind demeanor towards my mother.
