My AC wasn't working properly, I was so stressed, I called and spoke to Carlos, who set up my inspection appointment. Nick was the technician who came out to diagnose the issue, he then fixed my AC at the same time, and he didn't try to charge me anything extra. He was extremely helpful, knowledgeable, friendly and super awesome! I will be referring all of my friends and family to them as these guys are pros and they don't try to rip you off. Thanks Nick for making my Friday! I guess I won't be melting this coming weekend!! :)
