I contacted Airtron on Monday for a Friday appointment to check my AC unit that was making an unusual noise at the compressor, not cooling properly, and running all day. The didn't show up or call me. I couldn't get in touch with them over the weekend so I called Monday morning to tell them nobody showed up Friday. The unit and temperature in the house was getting worse over the weekend. I was set up for a Monday afternoon appointment. Another no call or no show. Now it's hotter in the house and compressor sounds like it might break any minute. Very poor company with horrible customer service. BTW this unit isn't even a year old. Still under their warranty. Maybe that's why they won't come out. I would shop around for a company that will actually help their customers if I were you. there are a lot of HVAC companies out there. Don't use these guys.
