I bought a Living Social coupon from AAA HVAC Services for a service appointment on our rental property’s 16-year-old HVAC that I’m preparing to list for sale. The technician kept me posted about his arrival time; was on time; was courteous and friendly; and extremely knowledgable about HVAC systems. He could have up-charged me for a pound of freon, but he was an honest person, and I very much appreciate that. I will look for another Living Social coupon from them and have them out to service our HVAC. Highly recommend!
