"⭐️⭐️⭐️⭐️⭐️ I want to start by highlighting the *above and beyond* service I received from Keep Smiling Heating & Air. In the midst of a brutal Atlanta heatwave, I called in a panic because my newer AC unit had suddenly stopped blowing cold air. From the first point of contact, the experience was incredibly professional and reassuring. I received a confirmation text, a follow-up call when the technician was in route, and even a text introduction with a picture and background info on the technician. Who does that? **Keep Smiling does.** Technician **Byron Solares** was exceptional—knowledgeable, professional, and genuinely empathetic. I explained that I have my elderly father with a breathing condition living with me, and Byron not only resolved the issue efficiently, but took the time to explain everything clearly. Thanks to his quick work, we’re resting comfortably tonight."
